No need to replace. The bearings in the older models did have a recall may years ago. There is no need to change the bearing. The OEM bearing are of good quality and will last as long as any other bearing in your engine. If your being told that they are week, then why not replace the crank and rod bearing also? Just my opinion. Good insurance would to be buy the extended warranty.

I replaced mine. The OEM bearings may be OK, but I know the Torringtons are good.
I wish I would have thought about getting the puller from Autozone, still it never hurts to have another tool....and since its a tool, it really doesn't count towards the cost of the cam install..

OK, I have replaced them. I now have another question. My rear cam gear is .020 lower than my crank sproket. The book says no more than .010. How many of you have even checked this after changing the cams let alone made the adjustment? I want to fire this thing up today....

Do a poll. Has anyone on this forum PERSONALLY experienced a inner cam bearing failure? The answer is NO. Many will tell you about a friend that had a failure, but non have experienced them selfs. That is a myth that has grown feet and has not stopped running. I read another post that a guy has 80,000 on his 09 Harley and has only completed normal services using non syn oil and has experienced NO mechanical issues. Bike is all stock, no upgrades, just rides the bike and changes his oil. I changed my cam myself and did not change the inner bearing. at this time i have not experienced any problems.

Torrington/Timken if you check closely have closed down their biggest plant in America and is mainly making bearings in Asia, this was due to Timken aquiring Torrington and needing to slash costs and maximize profits. I think Timken has 1 small facility here in the US. INA is a euro company with plants worldwide and a few in asia. This is just some info I have found while checking out this idea that some how a full compliment bearing (Torrington/Timken) in a low load higher rpm application would be superior to a caged version(INA) that is much more open to lubrication. Think this is leftover paranoia from the evo days.

>>Good insurance would to be buy the extended warranty.<< he is changing his own cams.....The warranty isn't worth using it to wipe up the oil he will spill..

Timeline?
I see George's website offers "B148" for the TC88 motors. Does my '04 RK (TC88) have the same inner cam bearing worries?
