JD 4400 Compact Water Pump

1880 Views 3 Replies 2 Participants Last post by  Jon
Water bearings failed while doing some slashing over the weekend. Managed to pull the pump off the tractor, after removing the radiator. But my question is, do I need to lubricate the "o" ring that seals the connection into the block or leave it dry? And do I need to torque the bolts holding the water pump to the block to any particular setting?

The technical manual seems to lack any information about the removal and refitting.

Thanks.

Welcome to DT!

I always lubricate O-rings with a lightweight oil or hydraulic fluid. If no specific torque specs are given, then you can just follow the chart in the manual fornthe given size of the bolt.
