Drill and Tap Gear cover. 18.75 to 1 ¼” NPT

Most of our gear boxes have drilled and Tapped four holes in the cover side of the 18.75 to 1 gear box.

This will allow you to remove the engine with out splitting the gear case.

We will drill the cover so the 1/4" NPT HEX SOC PIPE tapered plugs can be installed.

The four plugs are included, one has a 1/16" hole drilled in it for a Vent. 

This can be machined in both the OUTSIDE and INSIDE drive gear boxes. 

Most all gear boxes after 8-10 have this option, now standard.
