[TR] cam end float

[Gary Nafziger]

I'm assembling my tr-3 engine and don't understand this problem.  I've put on 
the front plate, inserted the cam and bolted down the front cam bearing only to 
find I have at least 1/4 inch of end play.  This is the same cam and front 
bearing i took off the engine.  In looking down the tappet holes it seems the 
cam lobes don't line up "centered" on the holes when the cam is pushed all the 
way back but they do line up when pushed farther forward.  Leading me to wonder 
if there's a spacer or something at the rear of the engine.  The machinist had 
already installed the end cap/plug at the rear of the block so i can't see in 
there to see if anything is missing.  I see one of the cam bearings has a set 
screw............but I assumed the front bearing controls the end float not the 
bearing set screw.  


any suggestions?
