Differential Seal Replacement - GL1000

Post by BIMWing »



Does anyone have any information about replacing the seals on the Differential for a GL1000?
I've been reading some of these threads on diff oil leaks but I didn't see anything on how to replace the seals.
Not sure which seals to purchase or how to go about doing it.
Or should I try the "restore" method first using some of the recommended oil additives such as AT-205 or Bars leak 1040?
I would prefer to do the seals then I know it's done properly, but I'm always up for advice... thanks.

None are available from Honda anymore. You should be able to match them up at a bearing house.
OIL SEAL (70X90X8) 91265-371-003 is the wheel spline seal.
SKF has this. https://www.skf.com/us/products/industr ... 20CRW1%20R
OIL SEAL (32X67X8) 91261-371-013 is the pinion seal.
123 bearings shows this. https://www.123bearing.com/seals/seal/r ... 2X67X8-NBR
OIL SEAL (35X52X8) 91265-371-003 is the axle seal.
Here is an NOS but it will be old. https://www.nospartsnow.com/nos-honda-g ... 3-371-006/
Here is a new one that would probably work and hasn't been on a shelf for years drying out.

Snake oils rarely work and not for long. Replacement is the real answer. However, because getting the new parts is not a slam dunk, if your leak is minimal, you might try something that will swell the seals. If so, run it for a little while until the leak stops then change the fluid again to keep the seals from just swelling up until they turn to goo. I've taken apart a lot of things that have had those type of treatments and sometimes all the rubber parts have been turned nasty. Maybe it stopped leaking long enough for someone to sell it, but it was no "fix".
