How to Reseal Your CAV Injection Pump Part1 (From an International Harvester B414)

This video is part 1 of stripping a CAV injection pump to reseal it.
Hello, I'm Lance (aka Bundy Bear), and doing these videos is my hobby. I do own Queensland Tractor Spares in Australia where I sell parts and offer technical advice to customers.
Parts seen in our videos can be purchased from www.queenslandt...
We have a lot more than we can offer on our website available to us and in our store. If you don't see what you would like please email [e-mail] or call 1300 850 097 and we will help where we can.
I do try and help with technical advice at [e-mail] if you have a question or are having trouble with your project.
The CAV manual is in the technical section of the Queensland Tractor Spares website above.

Lance!! I sure wish I had your knowledge and expertise!!!! YOU ARE THE MAN!!!!!!!!

Thankyou.

What a talented mechanic ( technician) you are Lance. I completely dismantled the CAV. DPA Injection pump on my old MF 30 (French horror horror) Tractor and rebuilt it with a kit from Queensland Tractor Spares. I followed the instructions from your MF video No. 14 & 15. I found it so easy to do although I did at times have a few nervous moments. In particular when the governor weighs fell out of the basket. I did think “What a bastard.” But I got them back, bleed the system and away it went. I must admit I was relieved when fired up. Thanks to your instruction I saved myself a lot of money.

[@BundyBearsShed]

That is good news, that is half the reason I do the videos. When Im parked up it will be too late to ask me.

[@charleshart6992]

Excellent video Lance - you always make understanding the process relatively easy!

[@BundyBearsShed]

Thanks Charles.

Lance, 5 years ago I followed you resealing another CAV and was able to get my JD 5300 back in service. My issue was the pump head had seized and sheared off the rotor. It took me a while to find a new pump head, but was then able to get it back together and working ..It runs great and I wanted to send my thanks! Regards from Pennsylvania!

[@BundyBearsShed]

Thankyou, That is good news.

G Day Lance, just the job, just getting home from Aberdeen after visitng Marshall for a week and needed something to chill down to, traffic was crap and I see you've got a new video out, bottle of wine and Lance nothing could be better. cheers many thanks Barry

[@BundyBearsShed]

G Day Barry, Im with you on that, a sip of red and a bit of KZbin is very calming.

It's been 50 years since I have taken an injector pump apart. Loaned a friend my book on doing this and never got it back. My 285 MF started getting fuel into the sump. Changed the lift pump and still leaking. Dealer was to busy to do it so I have taken it off. Going to a shop for repair. I know it will cost but know it will be checked out. Thumbs up Lance

[@BundyBearsShed]

I did a thorough video on the pumps in the MF135 6 speed playlist, videos 14 and 15 that might help you out.

Hi Lance - I have a fascinating "feature" with my 35x that has been there for 24 years (so not a major issue!) She starts and runs perfectly. However, just occasionally, if I have been running her at lowish revs (below 800 rpm) for a while she will hesitate in picking up when the throttle is opened (even running off load). She sits at about 800 rpm, sometimes for 10 seconds or so - no smoke and no sign of labouring. Its as if I have only slightly opened the throttle rather than opening it fully. After the hesitation she runs up to full rpm just fine and can then, usually, be throttled back and opened up just fine. She will run all day at 1500 rpm or over without missing a beat. I have over time serviced the lift pump, cleaned the tank and replaced the tank strainer, renewed both fuel filters and replaced the vanes in the high pressure pump (and stoned the slight marks out of the vane pump end-plate) and made sure the valve on the input to the pump fell under its own weight as you showed. None of this has made the slightest difference. Bleeding the system also seems to make no difference. Given that she works fine most of the time I'm slightly reluctant to pull the pump apart completely as I can obviously make things worse! Any thought would be welcome. Thanks.

[@BundyBearsShed]

G Day Colin, I think you may have a sticky metering valve, when the governor opens up it sticks for a little bit. You can pull the top ott and remove it without a full stripdown of the pump and polish it up and see how you go.

[@ColinMill1]

@@BundyBearsShed Many thanks indeed for the reply. I'm gradually overcoming my fear of delving into the pump - a fear that comes from having spent a week in the fuel injection repair shop at Ministry of Works in Nairobi when I was about 10 years old (a very long time ago now!) This left me with the impression that pumps and injectors could only be worked on by gods in immaculate white coats working at spotless stainless benches in a room that would shame an operating theatre and with a huge green Hartridge pump tester at its centre around which they would periodically gather and nod sagely as it clattered away.

Very informative video Great job Lance.. Thankyou for making your videos very easy and understandable for the lay person....

[@BundyBearsShed]

Glad you enjoyed it

[@pm270100]

good vid well done but i got an old TEF ////PS how hard is hard as 🤔🤔🤔🤔😁

[@BundyBearsShed]

I have a video on the old TEF pumps somewhere in the bowells of KZbin.

[@operatingengineer]

another awesome video! thanks you!

[@ulfrogeriversen2123]

Is it the same pump sitting in an 3 cylinder disel, mf 135 1971 model ?

[@BundyBearsShed]

Yes but I did 2 videos on the 135 pump in the 135 6 speed playlist videos 14 and 15

[@ulfrogeriversen2123]

Thanks for the answer 🙂. I have 8 speed not an multipower. but maybe it's just the gearbox which is the only difference on the tractors.

[@BundyBearsShed]

@@ulfrogeriversen2123 yes the engine is the same

[@jefftheaussie2225]

Lance, We have a Massey 1105 with the turbo 354. The pump has a pulsation damper on the front of it which is letting fuel out of the equalisation hole in the front of the damper and making a big mess. From my internet research it appears there are two different ones depending on the pump serial number. I will get that number later. Does QLD Tractor spares have these dampers and is there anything I should know about replacing it? Thanking you, Jeff.

[@BundyBearsShed]

We may still have them but we sell very few and if we don't have any in stock we could order some I'm sure. Call the 1300 850 097 number.

@@BundyBearsShed How to buy

[@jamesbarron1202]

I’m getting a lot of diesel in my oil after my tractor sets (Ford 3600) Is that from the main seal at the 35:00 point in this video? If so can that be replaced without tearing into the other parts of the pump? I guess I can just buy that seal instead of the whole rebuild kit?

[@BundyBearsShed]

Yes it can be replaced on its own
