Raw water pump

Hello... both my pumps on yanmar 3 gm 27hp broke down (exhaust water intake and engine cooling) broke down ...shaft seals leaked. Took a month by the time parts arrived in northern BC. Is there a way to repair shaft seals (not impellar - easy) but the seals on the shaft. What special tools would I need.

Thanks in advance

GAry

You have two pumps???
I am not sure what the pump is. I can only imagine they are Jabsco. Many of the Jabsco have a replaceable front seal. You flick it out with a screw driver and tap a new one back in. If not, then you will see a nut the shaft goes through. This type of seal is a packing gland type. Either tighten that nut or if that doesn't help, then replace the packing.

Pump

Thanks Alan... the pump is jabsco 2760-003 also 12066-0000.... those are the numbers on it. As I recollect there is a shaft with a small seal around it. The shaft has to be pounded out and a new seal applied.

Do you know of any place where one might order up a rebuilt pump?

Gary,
Do you have the parts there? I can supply an exploded diagram of the water pump">raw water pump. Usually the circulation pump is replaced as a unit.

Never Monday

Hi.... and thanks for posts everyone. When the pump shaft seals deteriorated and started to leak, I took the pump into a diesel shop. They replaced the seals and gave me back the same pump. What I would like to know is how to do this myself and what tools will I need. I suppose next time I get near that shop I will drop in and see if they will show me how and with what.

Thanks...

Gary

BCguy,

I don't think it's that easy!! I have a pair of 1GM10's and yesterday removed a leaking raw water pump to do essentially what you're suggesting.

Disassembly was easy. However, I'm still working on removing bits of the old seal as they did not pop out in one piece as previously mentioned in this thread. In addition, the pump was loaded with silt and some of it got into the seals. You guessed it.... grooved pump shaft.

I don't believe this is easy at all!!
