I took the clattering CC HR lifters from my brother's motor and decided to give them a thorough inspection. The CC directions say to not immerse them in solvents to clean, they recommend to just wipe the exterior prior to installation and especially to be careful of the lifter wheel that is pre-packed with grease. When I installed the lifters, the plungers of all the lifters would not move. I could press as hard as I could with a PR and there was no movement, I thought that was strange. Fast forward to two days ago and I decided to remove the retaining clip, which is a spirol lock similar to a piston pin but much smaller. I got the lock out and removed the PR cup and flat disc below it and tried to push doen the plunger and it would not budge. I placed the lifter in a jar of fresh toluene and started to pump the plunger. After a couple minutes I got the plunger to move easily and bottom out, then did the same to the entire set of lifters. There was so much gunk that came out of the lifters that it turned the jar of toluene black. Now all the plungers easily depress and bottom out, all the spring tension is consistent except two of them were slightly stiffer than the rest. Anyone who has a new set test if you can depress them, I have a brand new set and they will not depress at all. After thoroughly they can be depressed like they should. The Crane HR lifters I put in my brother's motor depressed easily and worked flawlessly on first start-up. Apparently the lifters need to be thoroughly cleaned before use despite what CC says, there was so much gunk that they wouldn't depress which blows my mind. I forst soaked them overnight in toluene and tried to depress them but they wouldn't budge, the PR cup gad to be removed to clean them.
