Solid Lifters for 2019+

That's a lot of money to just modify the lifter and the rest of the parts. Before I'd do it, if I ever have say a push rod failure, how do I avoid having to buy another complete kit ?

Pushrod failure? What?

This is a fix for the collapsing lifters in 2019+ Cummins. Doesn’t apply to your engine anyways so don’t worry.

There’s been cases of cam wear and you can hear lifter noise under normal conditions on the 2019+ trucks. Time will tell just how robust the lifters are.

In any case, if my truck ever eats the cam, it will need the cam and lifters pulled anyways, so this would be the solution.

What I'm saying is the rockers are OEM Cummins. Are the push rods ? The piece they are making to install in the lifters are made by somebody. What if I need more parts ? DO I have to purchase the whole package, or are individual parts available. AND we do have some of these trucks where I work.

No idea about pushrods. EDIT: Looks like they are made by Manton for Wagler. 2019 uses a different ball end and on both sides, so custom pushrods are needed with different length, different ball end on one side, and the rocker cup on the other side.

Those spacers might just be machined by who offers the kit (Wagler). They are simply a replacement for the internals of the factory hydraulic lifters used in 2019+ Cummins. I’m sure they could also be made by someone with a CNC machine.

I’m sure if someone buys a kit, and ever needs parts, then they’ll sell them individually. By time parts will be needed though, I’d imagine there will be more options.

So are the hydraulic lifters part of why the new Cummins are so damn quiet? I was standing by a newer one today for the first time and could hardly tell the damn thing was running.

That’s one small reason, and it just gets rid of the slight ticking noise of the earlier engines. The main reason it’s quieter is because they added another pilot shot that’s only used at idle speed.

When I reduced that idle pilot, my truck sounded like a 2014-2018… so I added it back! Lol

I thought they had a true solid lifter upgrade, as well as the spacer / internals swap kit...

??? It is a true solid lifter upgrade.… Or are you thinking flat tappet?

From a performance and friction standpoint, solid roller lifters are great. Roller lifters usually only fail when the hydraulic part collapses and it bounces. Solid ones can’t collapse.

elephantrider said:

right. i think they offer a full kit with a correct cam and all the fixings... I should look vs. conjecturing on the forum lmao

The block design has changed with the new ones. Different bore diameter and new bore has a key way for the roller lifter centering key. The Cummins roller lifter cannot rotate in it bore, it can only bounce.

With that, it is impossible to just drop in flat tappets. FWIW, solid rollers are superior to flat tappet for a variety of reasons, hydraulic or not.

Ah but do you have to cut your frame to get the cam out??

Nope!😀

Shock88 said:

wait…this is all just to do the lifters?! i understand doing this for the cam but lifters?! maybe i haven’t looked into these newer engines too deep yet

Lifters and/or cam. The lifters come out through the cam hole and a stupidly expensive Mopar special tool is needed to do the job.

I decided to go with a Wagler Stage 1 tow cam as I’m not putting a hollow China cam back in.

krashDH said:

Easier eh? I take your world for it since you have a newer gen, but damn, when I did my 3rd it was a process!

Are you planning on doing a complete write up for your gen or just posting a few pics here and there on this thread?

Click to expand...

Of the actual cam and lifter install, I’ll do a write up.

Pulling the front end, no. Way too many steps. EDIT: Maybe I will when putting back together, didn’t take any pics taking apart as I was rushing as usual.

So the 2019+ roller lifters are not able to be removed from the top and not able to be installed from the top?
And it doesn't sound like wooden dowels can be used to hold the lifters up for cam removal/installation like on the 5.9L engines?
And the timing cover still has to be removed to pull the cam?
And a special tool for installation of the roller lifters.

Click to expand...

Pretty much. As the special tool is out of stock, I’m experimenting with magnets holding the lifters up, but I may buy/make another tool once I have a lifter in my hand.

StealthDiesel said:

Good grief, Cummins could have made some changes with the 2019+ engines to make it easier to service the cam and lifters.

Lol the idea is to make newer vehicle less serviceable and more like cellphones. Last Cummins to have a tappet cover was the 98.5-02 24v.

holy hell…well i have an appointment for a dealership near me for next wednesday…fingers crossed

Good luck with that.

It’s seems there was a hardening and hydraulic issue, but I won’t know until I get the lifters out. I’ll look over the rollers real good.

I’m contemplating spending more $$$ on going with the Jesel lifters too. Super expensive, but if this is the quality we can expect from Cummins, then I have no choice.

Also, I called Cummins and was refused sale of factory lifters as Chrysler has “exclusive rights” to sell those lifters.🤦🏻‍♂️

Stock valvesprings right?

Are any of the rockers galled or binding? Common on the early 5.9L CR engines..

Yes.

No.
