GB Water Pump Repair

Curt Cooke · Nov 28, 2014

Mine is in need of service. Discovered last night that I don't have an IT manual for my GB. Could someone scan me the page on the water pump? I think I have to separate the front of the tractor from the engine, but I sure don't want to if I don't have to.
Thanks,
Curt

You can remove impeller and water seal only by removing the front six bolt cover. The impeller is held in place with a roll pin in a castellated nut and LEFT handed threads. If you need to remove the pump for more involved repairs, you have to remove fan, radiator, and pulley from crankshaft in order to access nuts/bolts to remove pump.

As already stated; about the only components to the water pump are the seal and impeller. The only need to go further is if for some reason the bushings or berings in the accessory drive are bad. That would be the shaft that drives from the camshaft timing gear with water pump on front; hydraulic pump ( or magneto if it is old enough) on rear and distributor drive at the top... seldom see the drive bad.
