Thanks for the video. With the old backhoe stranded in the backyard, I bought a new injector pump + a sealing kit. I thought that once the old pump is removed, I might as well try to clean and reseal it. It went really well. My 13 year old son was in charge of the iPad, playing the video step by step, while I was getting my hands dirty. The pump was all clogged up with rust from the old fuel tank. Yesterday, I installed the old pump again and the 50 year old Perkins started right up. I have just returned the new pump and saved 700 USD. 😀

Did the round rear part as described in your video so well, the valve was a little sticky, put it back together, still no go for diesel out injector tubes, popped the top off and hello stuck valve on the kill lever. Running well now. Thank you again.

[@johnsouth4667]

i am extremely appreciative of your video, as a person who started a diesel mechanics apprenticeship in 1983 and the advice back then was , leave injector pumps to the professionals, also i learn by watching more than from the manuals, well! for $14 for parts and an hour or so to dismantle the top of the cav injector pump. my MF 50A backhoe isnt leaking fuel from either throttle shaft or stop shaft. i cannot thank you enough and i will be revissiting bears shed again im sure.

Absolute gold mate, thank you so much for posting, you got me sorted. You are a carbon copy of my father in law who died 20 years ago now, he worked all his life on tractors, Land rovers and an absolute wizard on balers, made his own service tools too. Keep up the great work sharing the info, your wealth of knowledge can then be used for ever and a day, unlike his, most of which died with him. Wonderful delivery too, you should be on tv. I've passed you on to others I know who will be interested too, thanks again.

Thank you Lance, retired farmer here who ran MF for a fair few years an now collected a fiat 550 with the CAV pump that needs work. Your video is great mate and what I like most is your bloke to bloke how you did the job and no bull shit or useless commentary. Your hour was all useful information. I've seen too many of 10 mins with 30 seconds useful. :) Congratulations job well done and I'm keen to see what else you have filmed in your workshop

[@franktaormina2073]

Hi Lance, I finally was able to get my CAT416 started. After working on it for 3 days I finally figured out what was causing my issue. I purchased a kit and clean out the top and side of the pump only. It had all kinds of gunk inside which was causing it to not start. I decided to keep the pump on the backhoe as to not disturb the timing. On the first day I removed the four bolts that connect the injector lines into the pump. Each one going to a piston head. I didn't notice at the time when I took the bolts out but one of them had a spring in the middle of the bolt. When I put the bolts back on I must have put the wrong bolt into the wrong line. I also didn't remember if the washers went on the top of injector line under or underneath the line. I started the fuel purging process by turning the ignition key on and using the manual lift pump on the other side of the engine. I couldn't get any fuel to bleed from the top bleeding screw. I checked the plunger and the veins as you said and all seemed fine. I then tightened each bolt on the injector lines and then continued using the manual lift pump to get the fuel into the injector pump. I followed the purging process from the manual. Finally after turning the engine over for a few times it started coming to life. It then stated but was very rough and I couldn't rev the engine at all. I then noticed one of the injector lines leaking badly and that's when I figured out that one of the bolts had a spring in the middle. I then swapped it out with one of the other injector lines and this time making sure I put a washer on the top and bottom of the injector lines. Made sure all bolts were nice and tight. I then started it up again and this time no leaks and the backhoe ran normal. I'm not positive if the bolt with the spring made the difference or the washers. It seemed I had air in the system and this may have caused the plunger to not work correctly. Still not sure if I put the washers on correctly but all seems to be working fine. Thanks to your outstanding video I had the confidence to open the injector pump and clean it up. Next time I just need to pay better attention when taking things off. This was by far the best video out on the web. Thanks so much Lance! I bet your video will come in handy for many visitors to come. Take care!

[@BundyBearsShed]

Frank Taormina Glad you got it sorted it makes you feel good when you finally track a problem down. Thank you for the kind words.

[@robbro137]

My tractor has a leaking injector pump. Leaking externally more than you would run the water to keep the pipes from freezing. I don't smell diesel in the oil but that lip on the front is likely hard. So I figure I'll take it out and reseal it. Thank you for your video ti give me a heads up as to what I'm getting into. I am a millwright working in a shop, but first and foremost a tinker that tries to fix my own things. So, once you showed it disassembled I thought ok this is something I can do. I am glad you are showing how to repair something that is sorta alien to onters.

Hello from England. I have to message my heartfelt thanks for all you have done for us old tractor owners. I was directed to your videos by a gentleman on a UK forum, when my top spindles were leaking on my Fergie 135's CAV pump. I have today used your video again, to give me the knowledge to strip and clean the inlet filter/housing. Thank you again, if you're ever in the UK, I would like to be able to return the favour in some way. Kindest regards.

You, sir, are an absolute legend!! I really appreciate your taking the time to go through the complete pump overhaul - my Leyland tractor currently won't start, and I'm pretty sure the metering valve is sticking (good fuel pressure to pump, nothing from injectors). Having watched your video I have complete confidence in taking the pump apart and getting the old girl running again. Thank you!

[@simonfarley7708]

And to close this out, I took off the inlet and top of the pump, followed your instructions, and she now starts as she should!

Good work, well done.

[@OlaGbolahan]

I'm having the same issue with my Leyland 245 with no fuel to injectors. I believe I need to open the top of the injector pump like you mention at 24:24 since it seams the shut-off must be stuck. Bundy or Simon, where did you get the gasket kit for this?

[@baxtersheakley5793]

I just serviced the pump top on a Yugoslavian IMT 539 deluxe, replacing the o rings on the engine stop and throtle spindles, to stop some significant fuel leaks. Your video is just spot on with detail and the brilliant advice. Once I'd watched this, the hardest part was the air bleed. It's a long time (circa 40 years!) since I did any engine work and this was really helpful, thanks a lot.

[@BundyBearsShed]

Nice work! Glad it helped.

[@jimward3458]

Lance... I've watched your videos on the cav pump dozens of times. Thank you so much for going slowly and making comments. I've been working on mine for many weeks now. I think the best words you said is, "notice the rotation." I had my regulator pin mounted to the right. Which no fuel could be sent to the head of the pump. Changing this pin in the regulator now forces the fuel into the head then of course into the injectors finally. Thank you so much for your efforts and advice. I found that the pump was very easy to work on. Thanks a million.

[@BundyBearsShed]

Thanks Jim, I did a better video in the MF135 6 speed play list videos 14 and 15 that you might like. I got more involved in the pump.

[@bernieduplan7181]

Thank you for taking the time to make this video! At 24:00 you explained my exact problem and I was able to easily fix it. You probably saved me over $1000 and it was easier than removing the pump and taking it to a shop.

Great news.

[@rickmiskovich3469]

Your video just solved my issue. I was driving myself crazy bleeding my 1960's MM G450 tractor and sure I was going to have to send in my injection pump. I could not get the fuel from the second bleed to the Injector lines. The tractor had not been run for more than five years, I got it started and moved out of the way for another project, the lift/primer pump leaked terribly. Replaced that and the filters and bled it many times. No fuel at the injectors. Tapped a few friends and called the dealer for help, everyone was of the same suggestion, "AIR". I bled it again and again. Pulled it several times over two miles. It was like the kill was pulled. Thanks to your video, I got the courage to open the cap and eventually found that the Metering Valve was not moving freely. I cleaned it with WD40 and that removed the film from the old fuel. Was able to bleed it cranking it and it is back in motion. Thank you, thank you, thank you.

[@BundyBearsShed]

Thanks Rick, I think I did a better video in my Massey Ferguson 135 6 speed series videos 14 and 15. I re watched this quite q while after doing it and thought I could have done a better job so I have a few out there now.

[@JohnWatkinsUK]

Thanks for this video. It helped me fix a problem I had on an engine that had been sitting for a couple of years. Fuel was getting in no problem, but not coming out the injector ports. I checked the end cap gubbins, which was all OK. I figured it had to be the pistons were stuck in, not enough pressure from the lift or vane pump to push them out. I removed the fuel in line (on the end cap) and poked an airgun on my air compressor into the hole (convenient that the connector has a rubber gasket!), then pressurised whilst turning it over. Boom, the injector ports started ejecting fuel, connected everything back up, and she now works perfectly!

[@BundyBearsShed]

Good job!

[@furyjay]

Long as I have been working on tractors I have never worked on one of these pumps. Now we have high pressure pumps with fuel rails pushing over 20000 psi under heavy loads. Sometimes I feel like a parts changer as we just replace the part and go about our business these new pumps cant handle contaminants like the older fuel systems of the day could. Thanks for the video sir enjoyed it from one mechanic to another always learning something new.

G day Eddie, Good to hear. This is a popular video alright and it has helped many, that is why I do them.

[@ludditeneaderthal]

That CAV pump is basically a slight modification of the Roosa Master/Stanadyne pumps used on all kinds of diesels here in the states, so this vid basically covers those for the most part as well. The differences are in the injection advance and fuel stops mostly, along with governor linkages under the top cover. The basic guts, however, are the same beasty, lol. The Ford IDI v8s (and the International IDI v8), GM 6.2 and 6.5 mechanical injection, even the Olds 350 diesel use practically the same as this CAV. Great vid! Nice step by step coverage, superb shooting, and great practical hints!

[@m16ty]

The Roosa Master and the CAV are very similar from a mode of operation standpoint, but some aspects of the pumps are very different. Pretty much everything under the top cover is vastly different. The drive on the 2 pumps is very different too. At least the CAV doesn't have the dreaded flex ring that comes apart.

[@timo294]

Hi Lance Just wanted to say a sincere thanks for this brilliant, instructive video. Your step-by-step approach, what to look out for and general commentary is what gave me the confidence to successfully tackle this job on the CAV pump on my Massey Ferguson 50A Industrial Tractor. As it transpired, the most difficult part for me was removing and re-installing the pump because of all the front bucket related bits that restrict access. Many thanks from a smallholder in the UK! PS. If you ever get the chance, would be great to see a video on re-sealing a Rotary Swing Cylinder on a Backhoe!

Thank you Lance for this video and all your other videos as well, it gave me the confidence to strip my 35 three cylinder pump that was not injecting after sitting for over 20 years with the pump empty of diesel, 43:09 in your video is where the problem was in my pump, the two plungers were stuck down and was not letting fuel in so as the rotor turned there was no fuel being pumped to the injectors because the plungers were not reaching out to the cam ring, got it all built and running again, now im not afraid to tackle another one. Cheers from Northern Ireland.

Dear Lance.I am repairing a Massey Ferguson 690 that suddenly lost power and ran unevenly with no engine power.There is blue and black exhaust emissions. She reached full revs eventually but is running very rough! I have changed the main fuel filter and there was fine sandy stuff in the sediment trap! I/we have completely drained the twin tanks and renewed the diesel fuel. It took 6 gallons minimum before the lift pump would deliver. I have cleaned the small tubular filter on the end of the CAV DPA Pump. Now then: because the filter which was completely "clogged" and did not come out reasonably I completely lost track of the re-assembly order!I would not have had a clue how it all went back together if it was not for your excellent and most helpful video! The Fibre Washer, Springs, Plungers etc have all got to go back in there somewhere and correctly! I am now going "Out There" to reassemble it all!The tappet clearances are all OK! I do hope it is not the head gasket "Gone"! She has history on that issue! That "Short Engine" has given me grief since we fitted it! When it is going it is fine but it has not done 20 hours as yet, trouble free! When it is going all seams well! Usually I/we do get good results with our efforts but I guess there is always one!I will let you know how I/we get on.All the best Lance. Rob Allen.

Yeah I dont worry we are well over 1 million views so we are helping many. I think I did a better video in my Massey Ferguson 135 6 speed series videos 14 and 15. I re watched this quite q while after doing it and thought I could have done a better job so I have a few out there now.

[@spreader4]

WOW this must be the most informative video have ever seen makes me feel i can do that on our scrapper tractor ,and i'm a cowman .

[@BundyBearsShed]

Thanks I did 2 better ones in the MF 135 6 speed series video numbers 14 and 15. I go further in and explain more.

[@bearwill4737]

Thanks Lance, I appreciate the walk through, and taking the devil out of the rebuild. Devoted fan from now on.

[@BundyBearsShed]

Thanks Bear, Bloody good name that lol.

[@bearwill4737]

Thanks Again Lance, I like it better than Barry. Also, I was going to tell you, Nice Viking beard you're sporting. Have you ever had your DNA done? Reason I ask, under your bottom lip, full hair across, not like an Englishman with bare butt spots under the corners of your mouth...lol I just had mine done for $100 bucks, I 'm 60/40, 60% Viking & 40% Native American. I wish we lived closer, I'd really like to do some O.J.T. with you in the outback. I'm already a certified mechanic from the service, auto's & trucks, but wanted to rebuild diesels from the ground up. but No openings. Best to you in the outback.

Thanks Regi

[@ElderlyIron]

Lance, Thank you for the informative video. I acquired a non-running Massey with the Perkins 3.152. I found the filter full of mud, which is the bacteria growth. After changing the filter and bleeding, I had no fuel to the cylinders. I cleaned the entire fuel system and then the inlet screen you show in this video. I installed an electric pump downstream of the lift pump and bled everything that was bleedable. After a few cranks, she lit off! I turned off the electric pump and it ran steadily on the mechanical lift pump. Now for the rest of the story... After 45 mins of idle time to come up to operating temperature, I drove it off the trailer. After checking out all the hydraulics and such, I slowly brought it up to max RPM. After about 5 seconds against the governor, it shut off just like you had pulled the fuel stop. Oddly, it was blowing quite a bit of black smoke when it got to the higher RPM range. I pulled the inlet again to check the bottom plunger and spring you mention, and all was well. I'm now at a no start condition with no atomized fuel exiting the exhaust. Aside from the shut-off and that inlet screen, what else could give me a no fuel, or no start condition? You just gained a subscriber as well! Jeff

[@jacobhamilton6065]

I have a ford 2000 with those same symptoms . Thrown more money at it than I care to admit . Didn't know there was another screen in the pump. Going to try that this week. Hope that's my problem. I'm to the point of just doing a rebuild on the whole pump.

[@BundyBearsShed]

I did a better video on in the Massey Ferguson 135 6 speed series, video numbers 14 and 15 where I go in further to the rollers and main pump plunger etc. that may well be of help. Also look at my web site www.queenslandtractorspares.com.au on the technical tab there is a free pump manual download. This is a good breakdown of what is going on.

[@watchjaredwork1487]

Love watching Aussie mechanics haha especially the ones that know what they’re doing!

Hey Lance really appreciate this video it's one of the best instructional videos I've ever seen.Really easy to follow.I just used it to rebuild the pump on a MF135.

[@BundyBearsShed]

Thanks, I have other videos in the MF135 6 speed restoration series. Video 14 and 15.

[@davidlanyon4780]

great video. I have a JD 1040 that is underpowered and no indication that governors are doing their job and this video has saved a lot of time with unnecessary stripping to check their operation. Thank you.

[@BundyBearsShed]

Glad it helps.

[@davidlanyon4780]

@@BundyBearsShed had the top cover off today and all seems well. Tractor is still unresponsive and when i used her yesterday the running was a bit erratic in that when at a set rev, a small movement of lever made a large increase in revs. Still under powered though. Any suggestions please ?

[@jhoncho4x4]

Thanks from the US. I bought an International 1800 Loadstar truck, with the rare for these trucks 6-354T Perkins turbo diesel; 152hp I drove the truck a few miles from the auction to my workplace for storage. It did seem to run very well, and the whole truck drove like it has been maintained; in good original condition. Has power steering, air brakes and drives better than I expected. I am researching this engine now and I think I like it alot along with the rest of the world. Nice to see a pump that I can rebuild myself. Items like the pump is what I was worried about; parts availability, cost, etc. Pleasantly surprised I can rebuild the pump myself. Mine has the Delphi unit; I will look for a spare to rebuild and store it under the seat. Thinking about fixing truck up and making a camper / tow rig out of it. Be easy since it's already in good shape. Tires look new and currently has a short dumping grain bed with removable sides to make a dumping flat bed.

[@BundyBearsShed]

Very satisfying doing your own repairs, My best videos on the pumps are in my massey Fergusson 6 speed playlist videos 14 and 15. hopefully that will help.

Awesome. After being told for so long you have to spend $$$$$ to stop the leak your video is a god send. I have a leaking gasket on my Perkins 4-236 with a hydraulic governor I am now confident that with a bit of care I can go a bit further and replace the seals which no doubt will be hard and will fail if not replaced now. Cannot thank you enough.

[@BundyBearsShed]

[@AhmadAli-mx3xn]

this is the most clear vid I've every seen it helped me a lot , but i deadly wanted to see how you but put back the pump in , for the timing cause im taring to disassemble main but i do not have idea about the timing . thanks again

[@BundyBearsShed]

The pump will just go back onto the drive gear in the same spot as there is a dowel and you can not put it in the wrong place. Then just line up the timing mark on the flange and you are done.

[@shafeboles2072]

A very effective presentation, may tackle my pump problem

[@BundyBearsShed]

Well you may as well have a go, what can possibly go wrong lol

[@seandwyer25]

Very useful video for this MF65 owner with a formerly leaking injector pump. I was so impressed I bought the Sparex kit from QLD Tractor Spares as recompense. It arrived this morning and, thanks to the tips and tricks mentioned throughout, I was able to have it sealed up tight in only an hour or so. Very grateful for the hint that the O -rings in the top cover could be replaced with the the pump remaining on the tractor!!! Started and stopped on the first attempt, did a happy dance and then it began to rain...all very good indeed!

[@BundyBearsShed]

G Day Sean, That sounds like you had a win, good stuff.

Hi Lance, I dont have a tractor yet, but I am after a small Ferguson to have for a half acre I live on to use to help pull a trailer while cutting the hawthorn hedge,I have rebuilt a diesel Debat quid, and I have to say this video is excellent in helping me know what to do.Thanks very much for such a detailed video and best for the future from Ireland.Cheers.Jimmy.

[@UltradogMN]

I have a Ford 3000 that the pump is leaking like a sieve. Though I have had the top cover lifted to free up a stuck metering valve, I am one of those who was too afraid to open up the rest of the pump. With your great video and your encouragement I think I will tackle the job. Thank you SOOO MUCH!!

Thank you so much for taking the time to make this video, it's a really excellent and detailed description of how to reseal the dpa pump. One question, are the cav dps pumps essentially the same as I have to re-seal one of these?

Yes I believe they are similar.

Add me to the big THANK YOU list. You sir are a breath of fresh air! I can now open up mine with confidence thanks to you taking the time to help those who are new to these pumps. Thanks for the rebuild kit part number also, its on the way. I have a Dresser Dozer I just bought with a Cummins 4B motor that has the Lucas CAV pump. It wont do anything past about 1/4 throttle and I ordered injectors for it and was looking for a reman pump, but after reading all about the more common pumps, I didn't feel good about tinkering with it, but when I saw this vid, and the details you went to making it easy to learn from, I now feel completely encouraged to redo it myself. Thanks for going out of your way to help people new to these. I would bet my pin is stuck. God Bless You!

@@BundyBearsShed Hi again, I noticed that there is a small amount of diesel weeping from the small 9/16 bolt on the bottom of the pump. There are two bolts side by side on the bottom of the pump. It's the small one. I can't remember what it holds anymore inside the pump. Can I remove it and put another copper washer on it or will something fall apart inside the pump? I can't remember anymore what it holds inside. It was only a couple of months ago when I rebuilt it but I can't remember. Everything else is perfect, just that small weep of diesel. I tightened it more but I am afraid of stripping it. Is there a reason it won't seal even with the new copper washer I put in from the kit? Thanks.
