Engine/Transmission (1994 - 1998) Those with new camshafts

[CBlack]

What were the rates for the install of a new camshaft?



I've heard anywhere from 12-15 hours of labor.

Mine was billed at ~10 hours.

 

[SRadke]

It shouldn't take more than 10. It can be done in 6-7.

Are your experiences with the long way or taking the "short cut"?

 

[Joseph Donnelly]

Replacing the lifters takes a while but is worthwhile.

Agree, even with 55K on my lifters it was worth the replacement.

Short cut?

 

[JMcCoy]

What performance increases are you guys experiencing?

Short cut?

Don't know if that is the right way to describe it, but I saw a guy who posted on another forum and used wooden dowels in some sort of way to remove his cam and replace it.



He said it saved him from braking down the engine.



That is the "short cut" I was referring to.

Spool-up is faster and EGT is noticeably lower. Also picked up a mileage modest increase. No down side, all good.

Thanks for the quick reply. Looks like one more thing to add to the list. hehehe!

That is standard procedure. Wooden dowels are used to pull the tappets up so the cam can be slid out from under them.

Same results I saw.



Peak boost may be slightly lower, depending on fuel/turbo combo. The air flow is still the same, but less resistance from more duration means lower boost for the same flow.



I noticed on mine it spooled quicker to 20-25 psi, 25-30 was about the same as stock, and 30-33 was a little slower than stock.



Stock cam I hit 30psi at about 1950 rpms, now I hit it at about 1975-2000 rpms, but its a lot more air at 30 psi vs the stock cam.

That is standard procedure. Wooden dowels are used to pull the tappets up so the cam can be slid out from under them.

Exactly, its a kit sold by Cummins.
