testing a diesel pump by installing in a 134 g

riveroadrat · Jan 22, 2021

Can you install a 172 diesel pump into a gas motor so you can spin it with the starter?

probably yes.... as long as the diesel gear mates correctly with the gas gears, it should work. Gota wonder if you could rig up a drill instead?? Weld a pipe coupler to a nut, and reduce down till a drill chuck will fit?

I might try that, could be a lot easier.

The pump gear will nor fit into the gas block. The bore in the lower guide for the gear is too small. The drill is a better way unless you have the injector connected and then it will take more than the drill to make the injector pop.

You can test one by mounting it in a soft jaw vise, and spin it with a electric variable speed drill. A 172 pump spins counter clockwise as viewed from the drive end. Al

I didn't want to pull the distributor anyway, thanks. I have a drill that I'm almost scared of, I might have to ductape a board to it.
