Onan 132-0161 Water Pump Seal Spacer
The Onan 132-0161 Water Pump Seal Spacer is a precision length component in the pump shaft stack. It carries no load in the normal sense but it fixes where everything else sits, which is why it has to be replaced with the right part rather than approximated.
Spacers are replaced when they corrode, when the ends fret or pick up, or when they have been damaged during a previous rebuild. Any loss of length or squareness at the ends changes the stack, and the result is a seal that runs cocked and a bearing that is no longer where it should be. This part is listed for Onan water pump 132-0147 on MDJF 15 kW generator sets.

Frequently Asked Questions
Q: Why is my new seal leaking after a rebuild?
A damaged or incorrect spacer is one of the usual causes, because it leaves the seal sitting out of square in its bore.
Q: Does it need lubrication on assembly?
A light film of clean oil on the shaft helps it slide into place without picking up on the bore.
Q: Does the exact length matter?
Yes. The spacer sets where the seal and bearing sit, so a different length changes the running clearances inside the pump.
Q: Can I make one up from tube?
Not reliably. The ends have to be square and parallel to a close tolerance or the seal will run cocked.
