"Make sure you take your time and do this correctly" as you tighten the nut instead of loosen it 😂 all jokes aside this is a good video. My truck sprung a massive leak between the vacuum case halves

[@alleycatiron4395]

Thanks for the video. 9 years later it helped me out. Great job helping us shadetree mechanics keep our rigs going and keeping money in our pocket. Cheers

[@thoroughbreddiesel]

Our pleasure!

[@hidros1461]

Thanks for the video boss, helped out a ton!

[@thoroughbreddiesel]

We are happy to hear that.

[@robertswanson4505]

Great video as always guys!! Thanks for sharing the knowledge

[@thoroughbreddiesel]

Thank you. That is why we make the videos.

[@rotohead1]

there is a support bracket that attaches to the side of the block and the pump. Make dam sure you re-attach that support bracket back on after you do the repair. This is a long heavy assembly that can cause other problems if you don't. It's a pain in the butt to get to it and get the bracket attached but it is a must to attach.

[@thomasmcglone6000]

Thanks for reminding me

[@CurtisDrew1]

Just pulled my P7100 Injection pump because I found diesel in the injector pump with the oil. I figure the Seals got hard, or brittle inside it. That means the engine oil has some diesel in it too. So I decided to go ahead and reseal the entire engine and vaccum pump while I have it off. (Had to strip the side of the 5.9L 12 valve because it's in a FERD, Class A, RV and it has to come out the bottom because the dog house makes getting to the left side of the engine impossible. Engine is under the floor) This video lays the vaccum pump rebuild out so easy. 2 Thumbs up! Going to bump up the ponies on the injection pump while it's being rebuilt because, Why Not! My 33 years old Coach sat for the last 10 years, (health issues) so ALL the hoses and belts in the Coach are being replaced as well. Something most UTube Channels fail to mention when rebuilding old equipment.

[@rodolfoplasencia4953]

Min 18:28 to hook up the reservoir in, you can rotate the cogwheel it'll make the dog hook/connect the reservoir male easier. Great video! Saving us the commons 1000s. Take care!

Oh man am I happy to have found this video. Sounds exactly what my problem is. Driving home on Friday I lost alot of power, truck was rolling mad coal (unintentionally 🙃) and I felt like I lost my power steering as well. I'll be looking at my hydraulic pump and vacumm tomorrow.🙏

[@gabe1254]

What was your problem? You get it fixed?

[@Countryliving_Drifter]

@@gabe1254 boost leak. Before going into resealing your vacuum pump. Check for boost leaks. I had a blown intake manifold seal. Plus other leaks in the system.

[@gabe1254]

@@Countryliving_Drifter Nice!, glad it wasn’t something serious. 👍

[@johnnytiboni6745]

​@Steve Saenz yes on the vacuum pump there's a vacuum line that goes to the brake booster right in the middle of that line is a T valve for a nipple for vacuum that little vacuum line feeds a little relay and distribution on the driver fender it looks like a little relay well there a nipple on that where a 1/4 inch vacuum line feeds from the T on the pump to there they rot off and then you have no 4x4 , a/c & heat only works on defrost vents until your mobbing on the freeway and have enough rpm then it works and also IT affects cruise control

[@Mj-CWO4]

@@johnnytiboni6745my issue is ac/heat on defrost only plus cruise control haven’t experienced steering or 4x issues yet

[@lotsofgtos]

So you install the "culprit" seal dry. Question, do you lube the seal before you insert the hydraulic pump shaft through it when you are engaging the drive dogs? Thanks !!! I need to do this on my '99, extremely good video !!!

[@theguy9234]

I put on a borgeson power steering pump and a vacuum pump from peter gould. It worked for a couple hours. Are borgeson hd pumps junk?

[@jimmcdonald546]

Why do we install the main seal dry instead of with oil?

[@truckcampertraveler7369]

Thank you !!! Great vid

[@thoroughbreddiesel]

Thanks!

[@jamessheldon8206]

My 01 leaking oil bad in the general location of the power steering pump is it more like this leaking and not my tapper cover or more likely my tapper cover? Leave a big puddle of oil after driving

[@RanmaSal]

Can you link the part number or where you got the new dog coupler?

[@itscountryboy1659]

Is there anywhere where I can just buy the seal retainer sleeve by itself?

[@jlnismo1004]

What power steering pump did you replace it with?

[@kevinr1704]

Would that seal being bad allow oil to come out of the top of the vacuum pump? There looks like a little weep hole on the top side and is leaking engine oil pretty bad and soaking everything.

[@knottreeservice6552]

Nice video

[@supermo26]

Grandpa's truck doesn't have the ring to press out of the bracket between power steering pump and vacuum pump. Is this stock?

[@kendallmastre3356]

i thought my power s pump went out so I changed it and still not my steering or my brakes work..i looked in the end of the vacuum pump and started it and the vacuum pump was spinning but I didn't check the drive dogs on the vacuum pump so that probably what happened is they broke off

[@currypendleton4051]

How different is this from a 1993 vacuum pump?

[@jacobboudreau3166]

Do you know if they make a kit for the earlier 5.9 12valve Cummins because I'm have a similar problem on mine.. Thx

[@thoroughbreddiesel]

If you have the earlier three piece vacuum pump I would suggest contacting Gould Gear and Electric for a rebuild kit.

[@dixiemae5042]

I saw someone else replace that inner seal without removing the seal retainer(collar) of course there’s the o-ring

[@jakevan45]

Mine is leaking from the main seal butted to the timing cover.

[@jeffweber144]

I bought a replacement pump gor my 95 and it came with one less tooth on the gear and won't mesh up!!

I put a new vacuum and power steering pump and it leaks at the shaft what can I do to stop it its brand new already

When I halfed the vacuum pump the dogs from the pump side are gone like mentioned. Where can they go I see em no where!?

Mine keeps leaking oil. It leaked a lot. I took it apart twice already and it still leaks. Not a little bit a lot... what could I be doing wrong?? Plz help

[@c-man6376]

I bought this kit from you guys and just finished re sealing the pump and am getting ready to put the vacuum pump back on, When installing the vacuum pump back on the gear case,which direction does the big gasket go on? The gasket seems to have a raised lip on the inner portion and don't know which way its supposed to face. Please help! I don't want any leaks

[@thoroughbreddiesel]

Give us a call!

[@codyaubin8626]

It appears to only be leaking from the main seal on the pump itself, can I remove it from truck and just clean main seal and put new gasket then put back in, or should I complete the additional steps you have in the video?

[@codyaubin8626]

Just going off the knowledge of fix only what's broken and only appears to be leaking from main seal

Goodnight ,guys Nice video , l need a vacuum pump ,!!

[@MrMagnum7220]

What about the vanes in the pump? Need to replace them if low vacuum?

[@thoroughbreddiesel]

They can wear out but we don’t hear of it much. Several 300K plus motors out there with stock vanes.

[@bmsperformance772]

I have a 95 12 valve would this kit work for that year?

[@thoroughbreddiesel]

The kit will work but this video is for a 2 piece vacuum pump so some of the processes may be different.

[@andrewstevens9246]

Do you have to remove the front cover to get the pump off?

[@thoroughbreddiesel]

No, the pump is removed by detaching it from the back of the cover.

[@hunterbuchananbailey]

Same thing happened to me! Lost my heat first, now I have no power steering or brakes! Will this fix it?

[@thoroughbreddiesel]

No, sounds like you have something going on in your power steering pump. Resealing the vacuum pump will stop any oil leaks and get the vacuum pump back working correctly.

[@LoganC1988]

It really is this easy. Getting the assembly off the truck was a nightmare

[@thoroughbreddiesel]

Your right, it takes more time to get the vacuum pump off than it does to rebuild it.

[@1stgenclub619]

Quick question would a vacuum pump off of a 2001 24v automatic work on a 1999 24v manual?

[@thoroughbreddiesel]

Yes, the pumps are interchangeable.

[@1stgenclub619]

Thoroughbred Diesel ok thanks

[@onlylikenerd]

my 2nd gen is leaking power steering fluid right under where the pump is, so this is probably the issue?

[@thoroughbreddiesel]

Possibly yes.

[@onlylikenerd]

Thoroughbred Diesel kits only 30 dollars so I'll go ahead and buy one and change it anyways.

[@texas4434]

Where is the leak point Mine is leaking at the point where it connects to the block. Could I just un bolt and slide a new contact seal

[@thoroughbreddiesel]

Ours was leaking at the seal between the bodies. If yours is at the mounting gasket, go for that.

[@JohnDoe-ud2cc]

If you have a vacuum leak somewhere, will it make steam or vapor come out your oil cap???

[@thoroughbreddiesel]

A little vapor is normal at operating temperatures.

[@cholochedd6752]

Got a 97 dodge 12Valve I got no power steering and no brakes! Could it be the vacuum pump?

[@thoroughbreddiesel]

Could be the power steering pump or the vacuum pump if it has a booster.

[@rubikrawler]

I'm going to do this in a few days. I have a question for you though. My PS works great all the time, but I seem to have an occasional vacuum problem that makes my brakes feel as though there is no vacuum getting to them (solid pedal). It always goes right back to normal. If there something on the pump I should be watching out for, or look for the issue elsewhere? Also, thanks for the Bean's tappet cover, can't wait til it gets here.

[@Dirtyol12valve]

Could simply just be a vacuum leak.

[@rudychacon7175]

I have a solid pedal in mine too but all the time. I started to tear into it

[@TriStarGearhead]

Are you sure that your brakes are vacuum? These trucks use hydro boost brakes.

[@rudychacon7175]

@@TriStarGearhead 2500 uses a brake booster. 3500 uses hydro booster

[@TriStarGearhead]

@@rudychacon7175 Vac and hydro are both brake boosting methods. I have a 2002 2500 ram with hydroboost.

[@Mj-CWO4]

When removing the vacuum pump do you need to remove engine oil first? Also, what is the part # for the dog if broken?

[@thoroughbreddiesel]

No you don’t have to drain the oil. If the dog is broken, I would replace it.

[@Mj-CWO4]

Thank you

[@algorithmscollide8489]

Does this work on a 93 12valve?

[@thoroughbreddiesel]

The seals are the same, yes, but getting the 3 piece pump apart is different than the assembly shown here.

[@haywardstewart2825]

Can the power steering pump be rebuilt ?

[@thoroughbreddiesel]

We do not offer a PS pump rebuild kit. We actually do not see a lot of PS pump failures in these trucks, but I assume someone offers a rebuild kit for it.

[@timothyball3144]

Thanks for this. I also like the hint of checking to be sure that one nut is tight before loosening it. I do that quite often myself. I'll be sure to check the vac pump before doing the tappet cover.

[@thoroughbreddiesel]

Thanks!

[@methodatx01]

Torque specs? So I don't over tighten...

[@thoroughbreddiesel]

Bearing housing to vacuum pump housing = 22 ft lbs, power steering pump to vacuum pump = 18 ft lbs, the two bolts holding it to the gear case = 57 ft lbs, pump support bracket to block = 18 ft lbs, nut on power steering pump = 18 ft lbs.
