timing chain replacement
 
OK...!"/$%?&*...I am in the process to replace both timing chain on my 3.2...Left side is done...no problem there...On the right side, I linked the new chain to the old one and turned the crankshaft to feed it...No problems...I was almost at the end of the process...just to engage the master link...and the !"/$%?&* chain slipped off the intermediate shaft sprocket...I am probably not the first one to do that...so...How can I put back that chain at the right place on the intermediate shaft sprocket...??? Please...Help...!

What procedure were you using to replace the chains? Please explain in detail. It's important (IMHO) since you do not have the benefit of the strainer access.

Did that once,

The engine came out,
Cam chain housing removed,
Fished around with a coat hanger, wire, string, fed the chain around the sprocket and turned the engine by hand over.

Pain in the butt!

I used the procedure detailled in Benthley's manual and in the Wayne's book on 911 engine...Tensionner and idler are removed...I removed a link on the old chain...I removed the pin and the cam sprocket...Put the 930 at 45 degrees...attached the new chain to the old and turned the crank clockwise. All went very good...When I put back the cam sprocket and attached the master link...the chain got some slack and has fallen from the intermediate shaft sprocket...I know I will have to work to put it back on the sprocket...I just want to know if somebody got a better trick to do it...

Read this:

Notice where he made a flexible plastic tool. You might be able to use this tool to get the chain back on the intermediate sprocket.

If not, you may be able to use the tool in reverse and pull the chain back, reset everything, and start over.

Thanks Patton...I will work on that this week and will keep you informed with the winning method...
