Water in final drive

[Sylvester]

Just drained the rear Hypo oil and there was milk in the oil. It was changed in March and about 7000 miles ago. I went on a rideabout to Omaha-Dallas-Charlotte and rode in a fair amount of rain but not terrible. What seals do you think are failing? The bike has 131,300 miles.

Are you seeing any leakage?

 

On the top of the pumpkin is a covered vent. I would think some water may have come in thru there. Also, check the O-ring around the speedometer pickup.

No leakage, vent appears clean and I have no other thoughts.

i can't believe all the miles on that bike!! gives me hope for mine, i only have 30,000 but were sure trying to put on more.....

I don't see how any of the oil seals would let water in but not let oil out. I would guess to say that the water came in through the vent on top. It doesn't take a lot of water to make gear oil look messy.

the water can wick into the vent when driven in a heavy downpour, however it is more likely to be from condensation being parked or stored in a damp area, or stored under a tarp when the engine is still warm.

if you don't see any leaking, or loss from your fluid level, then don't change any seals.

just service it often.

Have you used a pressure washer on your bike???

 

Did you wash it at the car wash?
