Title: Setting TDC..
Post by: ZeroG on May 19, 2007, 08:05:02 PM

I am in the middle of replacing myu headgasket, I have the timing covers and chain removed as well as the cam sprockets.

I currently have the head tq'd to the block and the head is a TDC with both Cam lobes for cyl. #1 pointing in.

My problem is setting the block at TDC, I pulled the spark plugs, and placed a extention in cyl #1 so that I can watch the piston go up and down.  No matter what I do when the cyl is at the top I cannot get the TDC pin in.  I know that this totally has to be perfect or the cam timing will be off when I put it back together.

Does anyone have any ideas of how this problem can be solved.  No matter how many rotation of the crank, I cannot get the TDC pin in to put the timing chain back on the sprocket.

I think I figured it out..  I''ll keep my fingers crossed and report back.

Nice good to hear.  I ended up just sticking an extention in cyl 1 and then rotating the crank until it was at the top not moving or or down.  I also made sure that the waldorff key was facing straight up, and both cam lobes for cyl pointed in.
