Lifter replacement


PEE WEE

Recommended Posts

The only way to replace a lifter on an etech engine is to remove the camshaft. The lifters will have to be supported by magnetic tipped rods slightly longer than the pushtubes. There is a special tool that clips onto the rear of the cam to aid in removal. The cam weighs about 90 lbs with the gear.

Are you replacing the lifter due to damage? Better take a good look at the cam lobe, it could be damaged as well.

If lifter is damaged cam most likely has damage also so... do not reuse cam unless you are for sure it is ok , will need to remove unit pumps and rollers also to get cam out cam gear gets pressed off and heated up to be reinstalled.

If you think the cam is damaged, you can have it reground. I did one in my 94 E-7, reground the cam, reground the lifters, and had to buy one new lifter, saved a boat load of money compared to buy a new cam and all new lifters. Sent them out and had them back in about a week. If you need info on where I got them done, let me know and I will have to look for it.

Staxx i am or was like you untill i found out about a new method of grinding. No heat in this method. Its all in plating the lobs and then polishing or grinding and some i know of has been out two years that i have been around. Now the lifers have the finish reinstalled by a slice of something refused or welded to the face of the lifter . My self if i need a cam and have no more which i will not run out of them i will use these guys.In the past i have seen rewelded cams with bad results but this sounds like a good process to me.

Are you talking about the e7 or etec big differance on cam etec has rollers not saying it couldnt be done just dont know anyone that has had it done to a etec engine cam.
The E7 and the Etec would be a total mistake and i never tought of it cause i have only been two of those before i retired.Both had the dowel pin broken in the block.

Seeing how you guys are talking about the cam and Hrings I have a push rod that does not spin it seems to fall into a pit when I try to spin it and only spins half way and stops. Its causing the bridge on the valves to jump off.  Does this sound like the roller, H ring, or Cam?

Trying to see if this is a sign of either one. Am I removing head or just cam.

You need to be specific about what year truck you have on tool questions.

If It's an E-Tech the cam shoe google Mack J 41682.

The hold magnets google J 42425.
