Pinion Depth Tool

Pinion depth is a rough thing to dead-reckon, but that is the way we were taught to set up gears. Jim at AOE has been doing gear setups for a long time and uses this pinion-depth tool to quickly and easily figure out how many shims to add or remove to get it to the nominal depth. In this case, a Dana 44 should have a nominal depth of 2.625 inches and we were 0.015 off. Jim put in the correct shims and had both axles setup and dead-on in about a half-day’s worth of work.
