I have a Yanmar 2GM20F the raw water pump is leaking at the weep hole. I contacted my local Yanmar dlr the $ for the pump is approx. $500.00 + shipping & tax. Thats alot of money for a small pump. Any suggestions?

I do not think there is a rebuild kit for these pumps. If you can take the pump to a shop, they may be able to re-bush it.

No Kit available but the individual "wear" parts are standard .. Pretty sure that your pump uses 6202 Z ball bearings (2) and a standard lip seal (TC 13287, or Yanmar part # 124223-42080; check for your engine) which keeps the water inside. A good auto mechanic shop can easily rebuild it if you are not comfortable with the rebuild process.. Usually, changing the bearings is not necesasary but it is good practice.. The seal should be about $10 and the bearings should be around $20 for the pair.. A shop should be able to thoroughly clean it up and rebuild it in about a half hour.. unless there is something major wrong with it.. Good luck..

Call Depco Pump. They rebuilt my similar raw water pump for about $160 and stood behind it and repaired it again for free when I installed it wrong by over tightening the drive belt. These guys are very good to work with.

That kind of sucks?? Looks like Kloudie has already pulled numbers off bearings & seals though. The only glitch would be if the shaft is scored and they don't sell those..

Ron D, I rebuilt mine for less than $20. Buy the oil seal, bearings, O-ring, C-Clip from a bearing supplier (brought those parts I strip from the leaking pump there so that they could measure and supply me the correct ones). I wrote an instruction for this rebuilt as a reminder to myself. Send me your email and I'll mail it to you.

Yeah, the shaft is readily available too but it is a bit expensive.. If you are lucky and have a good small machine shop nearby they could make a shaft for you for less..??
