I recently purchased a 2009 1125CR (Sep 2008 mfg date)which has a very small amount of coolant coming from the water pump weep hole once in a while on warmer days. I am looking into buying the proper new water pump/seal for the future repair. I am getting some conflicting information regarding which water pump will fit. My engine(# YL049C00696)has the sight glass for checking oil instead of the dipstick. I heard that 2009's have an oil dipstick and the 2010 engines or at least side cases, have the sight glass and the 2010 side cases use the upgraded newer version water pump. Just trying to figure out what I have and which water pump to buy that will fit my engine, or maybe the weeping will stop after more riding as the bike sat quite a bit with the prior owner and only has 3,000 miles on it. Thanks for any help on this. Mort | ||

If you have a sight-glass for your oil, you have a 2010 engine. Unsure if it's possible to put '10 side cases on a pre-2010 engine. I have a 2008 manual, so no help. Go to a HD/B dealer and look at the 2009 and 2010 parts books( at the Parts counter) to see which pump you need. I fully expect you need the 2010 water pump if it's different than previous years. A very few folks have had to replace the pump. A fair number of folks have had a "weep" at the drain hole, without a serious leak, that dribbles then quits. If it's just dribbling, keep an eye on it but hold off replacing the pump till it really leaks. My 2¢ Z | ||

Thanks Z Well having the sight glass says the engine is a 2010 but the number stamped on the engine says it is a 2009 so maybe the entire clutch side cover was changed out for some reason. I did have my local HD dealer research the VIN for recall work and the records say it had the rear cam chain tensioner and electrical sub-harness recall work done. Not sure if they have warranty work listed as well. I will ask. The leak is an occasional dribble so I will just keep an eye on it for now. Thanks again for your advice. Mort | ||

I agree with zac, mine weeps occasionally but hasn't been more than ten drips a year. | ||

2010 models were built in 2009 - the build date does not reflect the model year. If you have the sight glass window then somebody has replaced the motor for a 2010 one - probably a warranty job. If it was a warranty job then they would have used the same VIN number as the original motor. The 2010 waterpump housing is Q1425.1AM and comes with the seal. The seal only is Q0426.1AM.

You guys were right. I was able to track down the warranty work and a 2010 engine was installed due to rear cam chain debris at only 700 miles. So now with only 2300 miles on the motor it has the water pump dribble. At least the motor is the néw one and the charging system recall work was done as well. Hopefully the 2010 type improved water pump dribble will not get worse! Thanks for your help guys. Mort | ||

If the leak gets bad then all you should need to do is replace the seals - the "pump" is an amalgamation of parts and not a unit. My 2010 leaks intermittently - it can be months in between episodes - IMNSHO I think it depends on how hot the motor gets, the liquid expands and pushes past the seals. Just keep an eye on the fluid level and check that the oil is not being contaminated by water. | ||

Think Engine Ice would help a bit? | ||

If you work on the water pump, make sure you synchronize it with the crankshaft at front TDC when you reinstall it, as the pump functions as a balancer as well. You don't need the special tool, a drill bit of the right size will work fine. Check the manual. | ||

no man a leak is a leak sorry and DO NOT use sealer | ||

Mine has never leaked while the motor is running. Only in the summer after shutdown will it occasionally weep enough to run down the case, but not enough to drip on the floor. I consider it a non-issue. 15,000 miles and going on 4 years of weeping. |
