I have a question for anyone that may have done a camshaft replacement on a 929 or 954. I was lucky enough to get my hands on a set of cams for my 929 and Im about ready to remove the old cams.
My question is where to set the timing. According to the service manual for the 929 it says you should turn the crankshaft till the index marks line up. This can happen a couple different places. To be sure it says to line up the marks when cylinder 1 is at TDC on the compression stroke. Cool easy enough. Done.
I then looked ahead at the installation portion of the manual and found that the marks on the camshaft sprockets were opposite of what they should be. To get the marks where the manual says, you must line up the marks on the crankshaft when cylinder 1 is at TDC on the exhaust stroke.
So we have two different possibilities and the manual contradicts itself. Has anyone else ran into this problem? What did you use for crank alignment?
Also what did you do about the chain tensioner? The book shows a tool that needs to be made to release the pressure. Is there any way around this?
Any help or info would be greatly appreciated.
