Tach Drive Oil Pump Plug Removal

#1 Post by Dennis Vogel » Wed Aug 14, 2019 6:49 pm

Is there some trick for getting the tach drive oil pump plug off? I've soaked it in Kroil for days and it doesn't want to budge. I'm reluctant to muscle it off for fear of damaging something.

It's already oil-soaked from the inside. I'd put it in a vise with a piece of plywood on both sides and lean on the socket driver. Or if you have an impact wrench, do the same an use that.

I usually go to heat after penetrating oil, particularly when the steel part is in aluminum. We used to call it the acetelene wrench.

Why are you removing the oil pump plug? Do believe there is excess "end play" in the gear that requires a thicker shim?
