installing cam on 750
« on: April 11, 2007, 12:35:21 PM »
Searched, all I found was a bunch of timing posts for ignition.  I need to know where to start on actually installing my cam back in place after a rebuild.

I'm used to single cylinder stuff where I just faced the cam upwards, turned the engine to TDC, and viola!  Finished!

But the 4 cylinder stuff is a little more tricky.  Can you guys tell me the process.  I should be able to pick up on it with just a brief overview.

Thanks in advance,
JP

     Set engine to Top Dead Center on 1&4( "T" mark on timing plate ).  Install cam so that key notch on the end of the cam is at "12 o'clock" position and slot is paralell to gap between cam tower lower bearing and upper bearing. Hope this is clear, manual states it better.

Thanks Scondon,

That was perfect.  I know exactly what you are saying.  What I was confused on was which piston would be at TDC, I figured lining up the cam would be similar to others that I have done- and it is.

Thanks again and wish me luck,

Thanks again :)  It is always best to have all the supporting info though, and the pics and diagrams as well ;) ;D

Treat it as four seperate singles and it dosenrt matter which of 1& 4 is at the top as they both are and the firing order aint determined till the cam is in, or to put it another way pick a cylinder to put at TDC then face the cam lobes for that cylinder correctly

Good point bryan, it never even occured to me to treat each cylinder as an individual.  And thanks for the post jonesy, deffinately will help to clear up any issues I may run into.
