Bearing Splitter 3/8 to 3 in. with 5 in. Gear Puller

A two-piece bearing separator with beveled knife edges that closes from 3 in. down to 3/8 in., paired with a 5 in. pulling bridge, forcing screw and two 3 in. threaded rods. Construction is drop-forged, heat-treated 40Cr steel with chrome and black oxide finish.

On a transmission or transfer case teardown this is the tool for bearings and gears that sit tight against a shoulder with no room for puller jaws: output shaft and countershaft bearings on manual gearboxes, speedometer drive gears, tail shaft and input bearings, pinion bearings, and transfer case shaft bearings. Slide the two halves behind the bearing, tighten the side bolts evenly so the bevels wedge in behind the inner race, bolt the bridge to the separator with the rods, center the forcing screw on the shaft end, and turn it down.

Pulling on the inner race with a splitter keeps the load off the cage and the outer race, so a reusable bearing comes off undamaged and the shaft journal is not scored. The separator also works in a hydraulic press as a press plate for the same jobs.
