'93 vn750 - excessive thrust in water pump shaft
Well, a few weeks ago my old hoss started making a pretty irritating squealing noise from the right side engine cover. Through process of elimination, determined it was a water pump problem.
Ordered some seals and parts, and tore into it today. Bad news - I was hoping I had a "wobbly" impeller causing it - turns out that it seems that I have an excessive amount of thrust in the shaft and it's putting the impeller into the engine cover *sigh*
From what I can tell in the shop manual, looks like this means a full tear-down into the lower housing (unless anyone knows a way I can do it short of that).
Although I do have a pretty solid mechanical background, I haven't worked with engines larger than lawnmowers lol - so looking for a bit of advice:
1. Is it really worth it? Ok, I know it probably is, but I need some reassurance.
2. Is it worth it for me to do it? Or are there any good leads on somewhere that I could get a rebuilt at a decent price? My local Kawi shop is telling me "anywhere between $500 and $4000" for them to rebuild it...
3. Any guidance on what parts (other than the obvious - bearings, seals, gaskets, etc) I should plan on replacing, if I am to do it? ANyone know of any rebuild kits/gasket kits, or do I have to order everything individually? So far having no luck tracking any kits down...
4. Any good sources for parts other than my local kawi dealer?
5. Any general words of wisdom?
I prostrate myself before the great gods of motorcycle mechanics seeking knowledge lol. Seriously - any thoughts/suggestions/insights/etc would be more appreciated than I could ever express...
