1930-1934 Water Pump Bearing Set with Roller Bearing, Leakless, Zinc

This assembly will replace your rear water pump bushing and pack nut. The short shouldered washer pictured presses into the back of the water pump, the other larger part that looks like a pack nut presses into the front opening of the rear bushing bore. The part that looks like a pack nut has a sealed roller bearing inside of it. This gives you smooth rotation of the shaft and eliminates the need to grease the rear bushing of the pump. Also eliminates having to tighten/pack the pack nut. The bushing bore in your pump casting must measure 1.015/1.016" in order to use this kit. U.S.A.
