I’m in the process of assembling my newly rebuild engine, and I'm installing the timing cover. The Shop Manual calls for special tool “Timing Gear Cover Centering Gauge“, J-966 to be installed over the crankshaft to center the cover. Well I don’t own such a tool and I not sure I could even buy one. Once again my lathe to the rescue. I didn’t have any stock large enough so I used a piece of hardwood and turned a sleeve to fit over the crankshaft with the OD the same as the harmonic balancer. Before I put a micrometer on the OD, I cut it a bit too small so I added a few wraps of the painters tape. Now its a perfect fit. Ready to install the timing cover!
