Are the Cummins cams made by garbage?

that whole lifter difference in the build and detail is so odd.

Wagler stage 1 as that’s all I knew about when ordering. I didn’t even know Hamilton had a setup.

I don't see any Cummins camshafts on the Wagler website at all.
Is it possible that Wagler is simply selling the Hamilton roller cam?

Their main site is outdated.

Anyways, Wagler doesn’t give specs, that’s why I recommend anybody to use Hamilton. They at least publish specs.

Yeah they definitely redesigned something. Even the body is more machined near the roller pedestal than before, which increases cost.

How the tool moves the lifter into position.

Magnet inserted into ball cup.

Lifted into position.

All lifted into position.

Cam installed.

Rockers and pushrods installed with .010” intake and .018” exhaust.

Your engine oil dipstick is inserted upside down.

Don‘t bullllllyyyyyyyy me; I DO NOT have OCD.

Timing cover and the whole front of the truck isn’t on yet…

And I’m also doing the HVAC box replacement TSB while I have the R134 and coolant out. So now I have to pull the dash🫣.

It pissed me off when I looked closer, but by then, I wasn’t going back out to flip it around lol.

Made these with my label printer.🤓

All things being equal, the engine will be louder with solid roller lifters versus the original hydraulic roller lifters!
However since the engine is "lighter" and has a custom ECM tune, I'm sure you won't be able to tell.


@cumminsturbofreak what is the black clip/retainer on the cam gear?


Man I would have been tempted to install head studs at the same time.
However lack of stock and I noticed yesterday that ARP 625+ head studs now retail for US$1600 (CAD$2200). Holy heck...

 

[elephantrider]

yup, wasn't sure how the lifter would affect the overall noise, with the other enhancements for nvh with the cgi block.

That is a spring loaded scissor gear. It removes lash and eliminates gear train noise.

I was thinking about headstuds, but I can’t afford that kind of expense right now for a maybe. I’m out about $3500 in parts so far. Maybe at a later time.

I should hear a difference actually because the cam has slightly different duration and timing.

Ordered that stage 1 kit myself....did the jessel lifters tho...I'm local to wagler and later this summer I'll have them install them...with the change to the lifters are you @cumminsturbofreak going to run 15-40 oil again or?

Probably.

 

[cumminsturbofreak]

WOW!

So I started it, and, boy is it QUIET! No more ticking above 1500rpm!

And as a bonus, exhaust sounds great with the cam!

Right on man!

Not sure I would want that anti-rattle assembly to ever fail in the gear train.
KDP all over again. Hopefully it is stronger, thicker, more substantial that it looks.


The engine does sound great.
Running it at 1500 RPM to break in the roller cam and solid roller lifters?

There is for sure a break in procedure for flat tappet cams plus a zinc additive at break in time but I don't recall a break in procedure for roller cams.
Of course my experience is with roller cams in gas engines like my older 5.0L Mustang and various GM LS truck engines.
