sprocket on water pump

[Thom Kelly]

Ron here is a picture of my water pump. The markings on the block says IXB5 is this not the motor for this machine?
Thanks Thom.

I havenÃ,´t seen that construction for a waterpump on a OC-3
as i know the engine called ixb3 for oc-3 and they have magneto ignition and were mounted on the rightside of engine.

either the engine been changed or itÃ,´s some experimental made

maby someone else has a better awnser.

Somebody changed engines. Cletrac/Oliver only ever used the IXB-3 engine. The IXB-5 has five timing gears instead of three. That is how they drive the water pump on the IXB-5 Before say 1940, The Silver King tractor used the IXB-5 engine as well as some fork lift trucks.

The Leader tractors also used the IXB-5. That sprocket drove a flexible coupling made from a double roller chain. It drove the hydraulic pump on ours.
