If you rotate the engine in the normal direction only, all the slack will be pulled out of the correct (left) side. It is taken up on the right side by the tensioner.

I will have to look up the installation procedure for the IP on th 603 -- I believe you must pre-tension the timer, it's not like the one on the 61x engines.

Proper procedure is to install chain and set cam to crank timing correctly, then install IP with engine pointer on 15 ATDC. It's a good idea to verify the pointer when the head is off, but I'd leave well enough alone now!

I'll post again after I dig this up on the CD.
