water pump need to be changed with timing belt?

Postby lovemyzx9r » Wed Aug 29, 2012 10:46 pm



i am asking this because i know on honda cars you are supposed to. our 1200 makes an odd whining noise that gets louder with the revs of the motor and sounds like a screw is bouncing around in the timing area when u pin the throttle. the belts were recently replaced and the mechanic didn't say anything about it. any ideas?

No, the water pump is completely separate from the timing belt. The water pump is driven off an internal shaft that also drives the front oil pump. The timing belts are external to the engine, and are driven from the main crankshaft. If your water pump is functioning and isn't leaking, then it doesn't need to be replaced.

There should not be a whining noise however, that can be caused by timing belts that were tensioned too tightly.

When you say it sounds like a screw bouncing in the timing area - do you mean by the timing belts?

if the timing belts are in the front of the engine. then yes the odd noise is coming from there. i'm guessing the belts are not hydraulically tensioned (i will read the manual and figure it out). thanks wingadmin you are the man. i will take a look and make sure. goldwings and silverwings were my least favorite bike to work on but the job security is fast making it my favorite bike to work on :). lots of labor. takes an hour to get to every 10 min job lol. i know its off topic but do the goldwing docs ever organize member rides by state or region?

The timing belts hang off the very front of the engine, underneath the two covers you see on the front on either side. They are tensioned with tensioners that use springs to set the tension during installation, and then are bolted in place so that the tension doesn't change (the belts don't stretch, ever, so no reason for hydraulic tensioners). If the tensioners are set too tight (or very loose!) during installation, you can get belt whine as a result.

No member rides ever organized - think people would be interested?
