I recently helped a friend with a very tight motor after a fresh rebuild. We could not turn the motor over with either the starter or the crank. I made a tool that I could use the breaker bar with and bolted this plate to where the starter is mounted. With the mechanical advantage and also the leverage from the 14 inch breaker bar, it was almost effortless to turn the motor over.

| I used an old bendix drive gear to engage the ring gear. I used an old cluster gear shaft (.75 inch diameter) for the main shaft. I drove the bushing out of the starter end plate and used the collar that is staked to the bendix and holds the gear on the drive. This collar maintained the same spacing as the normal bendix drive would have in order to mesh properly and fully with the ring gear. I installed a .75 inch bronze thrust washer and a .75 inch collar with a set screw on the "outside" face of the starter plate. The collar is used to take up any end play from use of the tool. I drilled a grease hole and pressed in a modern grease zerk so the tool could be lubricated. I cut the shaft from the smooth end of the shaft. For the drive nut, I used a .75 inch nut and with a drill bit, drilled out the threads. I placed the nut on the shaft and filled the cavity (cavity is created by shaft notch for the retainer (part # A-7155, Countershaft & reverse idler shaft)) with weld and welded the nut to the shaft. The bendix drive gear is welded to the other end of the shaft. Use the same bolts as one would use to install the starter. Correct direction of travel with the tool is a lifting motion with your wrench towards the motor. TED Kuchta (member MARC & MAFCA)
