954 Water Pump Leak

Has anyone else had problems with a water pump leak on their 929/954?

I noticed a small leak along the bottom edge of my water pump. It appears that it has been a small leak for a while but I never had any fluid drip on the floor. I inspected the hole in the back of the water pump and its not clear if the fluid is from a bad mechanical seal or bad o-ring. Since the dried fluid was all across the bottom of the water pump I am going to remove the water pump and change o-ring on the cover and put a new crush washer on the drain bolt along with a new o-ring where the water pump fits in the motor. This option will cost about $13 to get everything shipped to me instead of buying a new water pump. I figure this is worth trying instead of buying a used or new water pump.

Re: 954 Water Pump Leak

You might try taking off your hoses and inspecting them and the hose connection points on the pump. The hose connection points (where the hoses slip onto the pump) were very corroded on mine and caused a leak. I cleaned them up with a wire brush and reattached the hose and it was fine.

The o-ring won't help you if you have an water leak. It is used to seal off where the water pump enters the block. If it were bad you would have an oil leak, not a water leak.

There is a gasket that could be leaking. It's part number: 19226-MCJ-000 and can be had from Cheapcycleparts.com

I have all the parts ordered to try and fix the water leak. I meant gasket on the cover instead of o-ring. I am replacing the o-ring on the shaft that goes in the motor since I pulled the water pump out to work on it. It costs under $2 so why not change it to prevent the chance of an oil leak once everything is back together. I order all my OEM parts from Ronayers.com out of NC. They are much cheaper for OEM parts. The parts plus $5 shipping from ronayers was $12.47 where the parts alone from cheapcycleparts was $11.07 without shipping.

The fluid was isolated to the bottom edge of my water pump so I hope it just a leaking gasket or drain plug washer. The hoses were stuck so tight to the water pump that I had to use a small screwdriver to seperate the hoses from the water pump. The inside of the water pump and hoses are very clean. No corrosion visible anywhere even in the radiator.

Weird coincidence, we removed the panels from the 929 last night and found a coolant leak at the water pump. I was actually signing on this morning to post about this and found this. On mine it appears that the leak is were the pump is attached at the block. I am hoping that it is just the o-ring. I wiped it all down last night and it is still dry this morning. Here shortly I am going to start it and let it warm up to operating temp then inspect. Just to be safe I am probably going to get a gasket for the pump also. I was just curious is it was more common for the O-ring to go bad or if it was more common for the pump to go bad?

There is an inspection hole on the bottom of the shaft behind the water pump. If fluid is coming out there you have a bad mechanical seal inside the pump which is not replaceable meaning new water pump. The o-ring on the shaft in the motor is to prevent oil from leaking out of the motor. I am hoping a new gasket for the cover will stop my leak. I really dont want to spend the money to buy a new water pump. Buying used may save some money but it could be bad or go bad very soon.

Yeah I am going by the book also, I am hoping that it is the O-ring too. A bit of a price differance between the pump and the O-ring.
Glad I noticed this now and not about a week into riding season.

After sitting for a while it appears that it is leaking a little at the block and the bottom of the pump is wet, but nothing at the inspection hole. Parts are ordered and fingers are crossed.

The shaft o-ring is to stop oil from leaking out of the motor not coolant from the water pump. If you have fluid near the inspection hole on the bottom of the shaft then the mechanical seal inside the pump is bad and you have to replace the water pump.

Re: 954 Water Pump Leak

Well I installed both seals and warmed it up and it appears I lucked out. No more oil or coolant leaks and nothing coming out of the inspection hole.
How did yours go backdoc?

No leak after installing a new gasket.
