impeller

[David Arnold]

I replaced my Sherwood impeller this afternoon;  after I had buttoned everything up and started the engine I realized that I had not put in the "O" ring.  There is no leak anywhere around the pump.  Can I leave the water pump in without the "O" ring or am I looking for trouble by not putting in the ring?

david, the o-ring is there for a purpose. you should take the cover back off and replace the o-ring. maybe nothing would happen, but do you really want to take the chance, especially at an in opportune time...jeff

Yup, just as I thought... I guess I know what I'm doing next weekend...  Now if only the darn bolts were facing front instead of being accessable only from behind the water pump.  Wonder who was asleep when they designed that one?

anyone have any experience with a "Speedseal" cover for the Sherwood pump? I see they make one, but I can't see how they adopt the quick fix cover. The Sherwood pump has no face plate and the either the entire pump ,or the entire cover must be taken off to replace the impeller. Any info appreciated before I send them the money.
Thx

David : The whole idea behind the "O" ring is to keep the water from leaking out between the bronze pump body and brass plate.  If it isn't leaking I'd just keep an eye on it and replace the "O" ring when you get a chance. 
With no leak you must have a great seal, so watch it.

Ron, That famous photo of Napoleon with his hand in the front of his uniform.  I think he was holding his o-ring.
