cummins 12 valve cam and tappet/lifter install

Instructional video showing process of installing cam and lifter in 12 valve cummins. Process would be similar on all 5.9 and 6.7 cummins. Always a good idea to run new lifters with a new cam, especially with a higher mileage engine like i have (200k)

Really good in depth video hoping to see more

[@carlt6932]

You are a great mechanic and a pretty good fisherman. Very good video.

[@buixote]

The best video on this topic!

[@syquest3]

agreed!!! great job man!!

[@HelloKittyFanMan.]

...that you're aware of.

[@daviddominessy]

Great job. Now, I'm ready to do the same thing

[@MikeD-ey3sx]

Hey man, you just happened to have 2 not so common projects the same as I am doing. I was doing some KZbin search to familiarize myself with the two projects and you happened to have posted both. You are very informative and thorough. Good job man😃!! Lt1 411 swap and a 12 valve Cummins cam swap.

[@HorsepowerTube]

Thanks buddy! You obviously have great tastes lol.

[@failingdisciple938]

Unbelievable. You’re one hellava mechanic.

[@josephlbrociousjr3951]

I'm number 53 Thanks for the video. I am a first time 2nd gen 12v owner for almost a year I need all the info I can get. I thought my front main was bad though now I Have learned its just the tappet cover up behind the power steering pump where you cant see , all I can see is the oil oozing down the side. I didn't even know there was a tappet cover there. anyway thanks again. I am more confident in tearing into mine now . I couldn't help but to subscribe and comment, there are not many videos out there that are profanity free.

colorful language keeps it real, I laughed at the 'holy shit' at 25:10 ! Patient job..

is that your purple heart plate? much respect! im a DV but not a purple heart. thanks for the video and your service. =)

[@daddadboy666]

Genius!

[@weepweep2225]

Like your content brother, question for you, went to do the kdp on my 97 and found some bad bad things in there 😒. PO had it fall out and it cracked the timing case so he took it to a shop I assume and they replaced the broken gears and what not but all they did was leave the dowel pin out and JB weld the case, it leaks very small amounts of oil but I would really appreciate what you think should be done or if it will be ok in your opinion? Apparently I’ve been riding with it like this for close to 90k miles and never knew the real issue inside. Subbed cause you make your videos well and are good enough that I can feel comfortable to attempt the jobs myself brother so thanks!

[@davidangel2083]

Hey man Do you think you could do something like this with a lifter job on a hemi? I’m a dealership tech and have been trying to think of an idea to replace the lifters without pulling the cylinder heads and this got me thinking

[@thecurtray]

i noticed that firebird auto tag and much respect to you sir. not easy to achieve a purple heart if that is what i am seeing. america-love it or leave it please. happy veterans day out there america

[@HorsepowerTube]

I tried joining the military but they wouldn't accept me for health reasons. My brother went and that's his tag on the car. Didn't bother putting it in my name until I had it running good. Thanks for the message I will pass it on to him.

[@thecurtray]

@@HorsepowerTube well your brother is a big of a guy to me. i would want him right up front with me. purple hearts do not come easy. try to find the respect he deserves and i understand the sorry ass brother thing as i had 4. thanks for video

[@HorsepowerTube]

@@thecurtray Purple heart is for being wounded in combat. The truck he was in was attacked by a guy in a car bomb. He didn't kill anyone tho so no virgins for him. I like to pick on my brother but I do respect him.

[@pacemetalfab]

Job well done! It would have been nice to see the lifers being pulled into place but I understand you are working alone too😀. And placing cameras has to be a heck of a challenge.

[@HorsepowerTube]

Pace Metal Fab Thanks! Yeah, that's the one shot I wish I included. But it really was as simple as it sounds, pull up. I'm sure this will help someone!

[@pacemetalfab]

HorsepowerTube , It's certainly helped me. I look forward to more of your Cummins work 😀😀😀

[@thankfullife7968]

Helluva job brother. Appreciate you sharing. Other than larger surface area with the 24V tappets, is there any advantage compared to replacing new with the 12V Tappets ?? Blessings from Canada 🇨🇦

[@HorsepowerTube]

Thankful Life nope 12v works fine. But if you have wider lobes on an aftermarket cam you get less wear. Either would probably last a very long time. Price is pretty similar so I went with 24v.

[@mdbadalmiah6808]

Please check engine timing mark settings and engine model check engine flaring mark settings thank you sir

[@renegill6389]

I never seen something like that some guy on KZbin didn't do the same thing you did working on a Cummins 12 valve

[@weepweep2225]

Hey brother love the content! Can I replace my tapper cover without removing the injection pump?

[@tommyboygunz3449]

Some people said they’ve done it but I feel like your best bet it to remove the pump. It’s really not that bad

[@Bigislandguy]

How long is your dowel your using? I bought 1/2” x 2” and I’m wondering if it’s too long.

[@windage]

did you already take care of KDP earlier? couldn't tell and you didn't mention it, also, did the dowels pull out of the tappets easily? Neat trick!..I am 2 hours East of Covington in hill country..I see you are in KY, but in the flat lands near a major airport...

[@HorsepowerTube]

windage I think kdp was done after before putting timing cover back on. Dowels weren't hard to get out with some pliers. Yup in KY right next to CVG.

[@ricardoleyton4913]

Pero es un motor cummins 6bt..y tiene la tapa lateral...y puedes cambiar el levas..pero en el modelo cummins 8.3 no se puede...alli es donde estoy preocupado..

[@Tbmx8]

Great video man @horsepowertube super helpful. I’m currently in the process of doing the timing case seal in my 2nd gen 12 valve, as far as making sure it’s all timed right I just make sure the plastic plug goes into place turning the crank clockwise, and then mark all the gears and I’m good to pull it? Thanks again

[@HorsepowerTube]

Yup that will work!

[@alejandroalejandro1562]

I know I am quite off topic but does anyone know a good place to stream new movies online ?

[@abelkairo4280]

@Alejandro Alejandro flixportal :)

[@alejandroalejandro1562]

@Abel Kairo Thanks, I went there and it seems like they got a lot of movies there :) I really appreciate it !!

[@abelkairo4280]

@Alejandro Alejandro no problem :)

[@laugh1958]

This is a great video, thanks for the hard work. I pulled my cam and buggered up the cam bearing. Does anyone know how to pull that bearing without pulling the head off?

[@HorsepowerTube]

I don't think pulling the head off would help any. Might have to pull the pan.

[@laugh1958]

Ended up buying a cheap blind puller and that did not work so we ended up cutting it with a hack saw. I was not crazy about doing it that way but we were careful and kept a vacuum running by the saw so hopefully the filings wont screw anything up. Thanks again!!!

[@HorsepowerTube]

Good luck!

[@nicks3012]

When you install the cam gear on the cam shaft is there any kind of markings to line up for tdc

[@HorsepowerTube]

Nick S it is keyed it only goes on one way.

[@MountEverestMetaverse]

I was replace the timing cover seal and I was turning the balancer pully to get it off and I didn’t know about the pin. Do I need to go in and replace it now?

[@MountEverestMetaverse]

I didn’t have the injection pump bolted off I just took off the belt and went straight to the balancer

[@3siddoway]

so my camshaft only comes out like 2" then it seems to be getting held up somewhere? the lifters seem to lift up the same distance but a couple of them are not lifting as high as the rest. Any suggestions

[@HorsepowerTube]

I'd say the couple low ones are the problem. They all gotta be up!

[@3siddoway]

Figured it out! The fuel lift pump needs to be removed before it comes out.

[@HorsepowerTube]

@@3siddoway that makes alot of sense lol

[@yuriypono3666]

What is the benefit to replacing the tappets to 24v ones?

[@HorsepowerTube]

Probably nothing on a stock cam. But the lobes on this cam are wider they are the width of the 24v tappet. More surface area to spread the pressure of the springs onto. Probably a good thing since I have upgraded stiffer valve springs.

[@andreyzagoruyko5390]

Only vid on how to do this, but I would say WHY you started drilling the holes instead of threading through the eyelets . . . because the string binds up in the guides and you can't pull it up unless you use tweezers or needle-nose pliers. But whatever, it's already said and done. I had to use a 3/4" x 3/4" 4' piece of aluminum edge to get the tappets out, but putting in was easy; I HIGHLY advise a second person who can hold the strings and pull them up and down as you do this; I also used a hi-powered flashlight but of course it was a cloudy day. Round the rough edges of the aluminum if you do this, so you don't damage anything inside, though it is a soft metal but will also help you slide smoother. and not get caught up on anything. Same way coming out and going in; top facing you. If they are smooth dowels like I had just cut a sliver in the top about 3/8 deep and make a tiny bevel to get it started; I used fishing strong fishing line and only left 1/4" excess past the knot. I was able to reuse my dowels but they were TIGHT, so be your own judge, had to wiggle them out with pliers. As for the height of dowels, no taller than 1-1"4 . . . the 24v are about a 1/4 shorter so going back in is faaaaar easier, with the half-pipe. -THANKS A TON!

[@LegendMuscle]

How much different is the 12v from 24v besides the injection pump

[@HorsepowerTube]

Very. I think crank is the same. But design is similar. You can swap alot of 12v parts into a 24v.

[@LegendMuscle]

@@HorsepowerTube thankyou. Great video. New sub here

[@carlt6932]

I wsh you would have retorqued the inner timing cover.

[@HorsepowerTube]

Yeah that would have been a good time to take it off and reseal it. Ended up taking it back apart later to do that 🤦. Crank pressure from 55psi of boost will find a way out if she's not sealed up tight.

[@1HSYURIDIA]

Why do you have replace cam and tapets??

[@HorsepowerTube]

I didn't have to. Just wanted to upgrade to a performance part.

[@1HSYURIDIA]

@@HorsepowerTube I asked because I have cumins 8.3 24valves. The rocket arm bridge came loose and came off and the shop guy said was unable to put it back and calibrate it and to much lash on cilinder 4 He said a cam problem or a Lifter He aske to put a new cam and tapers. .$3000 job thats why i asked What do you think..?

[@themechanicman3865]

How did you know that your cam was bad what symptoms were you having and are the tapets are bad I have an issue right now I started to have an issue with a my injection pump to wear the number one delivery valve was working intermittently ordered a rebuild kit for the pee pump but there's a lot more to it than just seals and aluminum little cups that you tap into the thing there's a lot you have to know about it show Ray shortly after that the thing started to develop a check and low oil pressure to where it sounds like it's coming from the middle of the engine I'm going to be doing piston rings I already got a new head new head gasket and I'm going to do rod main bearings also while I'm in there with wrist pin bearings for the rods haven't replaced the oil cooler yet but I'm planning on doing that too but I was thinking about going with a heavy duty push rod brand new tablets in a brand new cam just to be on the safe side I had a valve spring that broke it dropped the valve but it didn't destroy the piston and ever since that happened shortly after it's developed low oil pressure and a tick I wouldn't think that that happening would cause low oil pressure unless that was meaning to go anywayit had high miles on the truck over 400,000 me now but I originally had about three something on it when I bought it close to 5 years ago when I pulled the head off the day prior it says standard on the Piston so somebody's either put pistons and rings in it I don't know what else they've done but just to be on the safe side I figured I might as well throw a cam in it too Samsung fixing everything else let me know what your thoughts are and also the cam bearing should I replace them and could I be getting that rattler tick from them Cam bearing if one of them is bad thanks a lot

[@HorsepowerTube]

I didn't have any symptoms. I noticed wear when I took it apart. If you're having low oil pressure that would be from a worn oil pump or more likely excessive bearing clearances from 400k miles. You could try putting a fresh pump on it. Probably just needs a full rebuild. Or grab a 1-200k motor off someone for cheap. There are plenty around. As far as ppump goes I would have a shop rebuild it. There's alot of very expensive tools you're not going to have to make sure it's working properly such as flow benching the pump. Use yours as a core on a rebuilt one.

[@cwags4824]

You really should have installed a new gasket behind the gear case. It will be leaking soon

[@HorsepowerTube]

You're right. Would have been a pefect time to do it.

[@ervinfetherman9215]

Good video. way to cheat the system!

[@1HSYURIDIA]

Isnt better remove cilinder head to chk valves?? Also?

[@HorsepowerTube]

What do you need to check on the valves? Do swap a cam out no that's not necessary at all.

[@1HSYURIDIA]

@@HorsepowerTube Ok I see May be to chk for tapets or push rod. Or cilinde head bended valves ??

[@1HSYURIDIA]

@@HorsepowerTube I have cumins 8.3 24 valves When we opened engine we Had a rocker arm bridge came loose mechanic tryed to adjust it back too much lash but was unable because rocker arm was unable reach a push rod so mechanic said we need to replace tapets and camshaft without pulling cil. Head. But another mechanic said he have to remove the cilinder head to inspect valves and nake sure no bended. So i m trying to know whats the right and best job to do??

[@HorsepowerTube]

@@1HSYURIDIA should be able to verify valves aren't bent doing a leak down test or checking the height of the valve stem.

[@1HSYURIDIA]

@@HorsepowerTube ok You mean Dont have to remove head then??

[@johnniezuniga6841]

That's not the proper way to keep lifter from dropping down.
