About two years ago, at 60K miles my '77 wing developed an oil leak. I was advised

by people that should know that it was the water pump!!!! After $140 I realized that it was the oil pump seal, which I replaced. Now it leaked worse that before. I did this two or three times. Finally using a sheet metal screw to stop it.

Now, I am not that bad a mechanic. Since the new water pump was different from the old one I was wondering if the newer pump required a different oil seal?? I checked and there was indeed a new part number - but is the same size as the old one - 10X25X7 (paaart #91207-580-003).



The old seal was the same as the one for the shift shaft.



Any help would be appreciated.

Thanks in advance

Hi B.J.

A failure of the main seal in the pump will cause cross contamination between the oil and coolant, not a leak as you found out. The waterpumps though a bit different all fit the same and use the same o-ring seals. About the only way you can get oil or water coming out of the weep hole is if one of those o-rings fail. They are tricky to install because it's very easy to nick one and then the new one leaks. Lubricate the seals and the area they make contact with while being installed to help ease them in. Also check the area carefully to make sure there's no burrs or nicks in the metal that might snag them.

Failure of the water pump oil seal will cause an oil leak. It comes out of the water pump housing thru a small hole in the bottom of the water pump housing. The hole is there, I suppose, in case either the oil or water was to become under pressure.



Thanks,

there can be three causes of oil coming out the weep hole.....

1. failure the the water pump seal on the "oil" side;

2. nicking the O-ring on installation (very easy to do)

3. leaking around the crush washers on the three bolts which hold the water pump in the housing

I just noticed an oil leak,small, coming out of the weeping hole. It looks to me like oil,not mixed with coolant. Can I still ride the bike,81 gl1100,till the end of season,or I should rather fix it asap? And one more question to more experienced,is it oil pump?
Thanks, Mathew

Welcome to the forum mustasz!

You can ride till the end of the season but keep an eye on the oil level. Mine leaked for a few months before I replaced the seals. The leak was getting gradually worse as time went by. I bought a water pump seal kit from the dealer for about $17.00 I think. I thought about replacing the pump at the time but it was another $140.00.

I replaced my sealsabout 2.5 years and 30,000 miles ago. Haven't had a problem since!

It's definately not the oil pump producing the oil thru the weep hole, the oil pump is behind the water pump and inside the case with another seal between IT and the weep hole.
Now it is possible with the way the oil pump and water pump are driven by the same shaft with a seal in between the 2 that oil could get into the water (less likely) or water get into the oil (more likely because coolant is under a pressure when the engine is warm)
Either way you "should" (cross fingers) be ok riding til end of the season but keep a close eye on oil and antifrezze contamination and coolant/oil levels.
Coolant in the oil has the effect of wasting the internal bearings so I wouldnt advise putting it off, at least I wouldnt on my bike (that is, once I get it back together)

Serious sweet trick when you put the front back on the motor when changing waterpump or seals. Spray the entire area, all the orings , everything with silcone spray. It slicks everything up so well it just slides together with zero friction. No pinched orings!
