Re: 1946 B.F. Avery Model A Tractor Restoration
This is a distributor version of this engine. The hydraulic pump is driven by the governor in the place where a magneto would otherwise be. Since I was removing the hydraulic reservoir and lift control, I felt obliged to plug the pump, not having a good way to close the opening on the block. Since I wanted to further my chances keeping this puppy dry, I simply removed one of the pump gears so it won't build pressure.
The governor shaft showed no wear and in fact measured the same as a new replacement, so I left it. I did however replace the brass end bushing before reinstallation.
