Hello fellow enthusiasts!
I am rebuilding a 73 TR6 engine. I have had to purchase a new
replacement cam which I believe is original stock. It is not a modified
cam (performance cam). I have installed the cam and was putting on the
keeper plate with the two bolts. Before tightening the bolts down, the
cam was able to move freely. Once I tighten the bolts down, the cam is
very difficult to move. I put on the cam timming chain sprocket to move
the cam and found it hard to turn. I was told by a reputable source that
the cam should move freely and the bolts to the keeper plate should be
very tight. How many lbs? I am using the original keeper plate which
shows some signs of wear where it rubs against the cam. I am using the
bently book for assembly instructions and find no mention or any helpful
hints regarding the cam keeper plate situation. Any suggestions? I
really need to hear from someone who has rebuilt there engine and or
knows what they are talking about.
After I get past this small bump, I will be preparing to time the cam.
Any elaborations would be helpful.
Thanks for your help in advance.............Mike (S.E. Michigan)
