Water Pump Seal Replacement

 Part Numbers used:
  • 92049-1416 Water Pump Seal All years
  • 92055-1271 Water Pump O-ring
  • 92055-1424 Large O-ring this number shows different for an ’86 and an ’03. I ordered the part number for the ’03 and it worked for my ’86.

The three parts cost me $14.00 from my local dealer.

Remove the belly pan and the lower left fairing. Drain the oil and the radiator.

Remove the water pipe mounting bolt, the bolt is located under the water pump at about the 7 o’clock position. Pull the pipe out of the pump case. This is a metal pipe located behind the rubber hose.

Remove the gear shift lever
Remove the gear shift bracket
Remove the clutch slave cylinder. Here's the clutch push rod. The manual says to remove the rod, but you don’t need to, just be careful not to damage it.

Remove the hose attached at the bottom left of the water pump.




Next, remove the water pump cover.
Pull the pump unit out. The easiest way to do this is take the two screws from the cover and screw into the pump and that will give you something to hold on to so you can pull the pump out. You may have to wiggle it back and forth. The bolts are at 9 and 3 o’clock.

The pump with the bolts in place.

The seal is located on the shaft.

Remove the seal and replace with the new one.

Remove the two o-rings and replace them also.

[ Editor's note: when my seal started to leak, I happened to have a spare pump and used that. The mechanic at the local dealer told me that he had a 90% failure rate when replacing seals. Gene Kinzell, the best mechanic that I know, told me to put a little red Locktite on the seal after installing it. ]

Reverse the process to put things back together. The hardest part is aligning the pump shaft female end with the male shaft coming out of the engine. Make sure the pump is fully seated; when it is you cannot turn the pump by hand.
When you put the water pipe back on the bottom of the pump housing there is an o-ring on the pipe. Make sure it is on the pipe and push it all the way in until the pipe seats.

Fill with fresh fluids and check for leaks before putting the Tupperware back on.
