valve lash kills them!....they are like a set of rods..when there done theyll tell ya......keep checking the rollers and bearings for wear,i guess
Who changes their solid rollers and how often? I have had some guys say never and others each year. I have 66 hours on a offset set of Cranes and am wondering if I should risk another season.

I clean them in solvent. Clean all oil out of the roller needle bearings. Check the roller wheel for obvious "skating" or flat spots. I check the links to be sure they are ok. Then I roll them with HARD PRESSURE on the roller. Any tight spot...I feel anything and they are tossed. Otherwise I put em back in.
keep a tight lash on them.......trust me,lol
I do believe that's what "Rev kits" are for!..

rev kits???..didnt they use them in the 80's?
Yea, and some of us still have our lifters from the 80's because of them.
The last 20 hours this engine has not been over 6k rpm's. but it was built in '01. I keep the lash at .020 across and it has never been off but when one of the rollers craps out I will be pulling the engine which is what I dont want. Its not worth the risk I guess but I know a few guys that have over 300 hours on individual sets.
I doubt they are getting 300 hours on off set lifters. Its not worth the risk, I change them every 2 or 3 seasons depending on the amount of use.
If the boat see's alot of idling then I would pull and inspect every season. If the engine doesn't see a lot of low speed idling then I would check every 75 to 100 hours.
