I will be installing new inner cam bearings when I get the installation tool, but what about the other end where the cams rests in the cam support plate? One end of each cam turns in needle bearings, the other end just turns in the cam support plate. Doesn't it wear out also? How do you check it? I don't see any bushings that can be pressed in, so if it is bad, do you buy a new cam support plate? Couldn't find anything in the manual addressing this.

 

I agree with your reasoning but the cam plate is seldom if ever an issue concerning wear. A full race set up may be another story. Hope this helps.

 

im pretty sure they spin in a constant pressure bath of oil supplied from the oil pump through the cam plate. That being said, there is very little wear on the plate or the cams.


older twin cams had bearings in the cam plate. Newer models don't, they just slide into the cam plate.

 

Ya, it seems wrong, but they seem to work fine.

This. Pressurized oil.

 

the wear should be minimal, inspect the lower hole that goes over the crankshaft, that's the race that will get more wear on it. It's also a good idea to check the crank run out while your in there.

 

I was still worried about my cam plate, so took it into a dealer on my way to my daughters. They said it was too sloppy, probably because of a defective or low output from my oil pump. The service manager said my cams had too much slop on the non-bearing side although the manual didn't have any inspection criteria.

 

If there was too much slop you would see the wear marks in the camshaft bore in the support plate.

 

My Spidey sense tells me your dealer wants to sell a cam plate.

And a lot more!
