Just stripping down my 01 250 and noticed the water pump impeller had come away from it's shaft. I've got a new one today and Sherco have changed it, the old one was an all cast alloy affair but the new one has a brass center and a plastic body.

The old alloy one had seperated it's self from it's thread and would have not been circulating the water around the engine, I've only just bought it so I cannot say if it ever was getting hot....might be something to look at if your Sherco is overheating for no apparant reason.

I would guess that the later bikes would have been changed by the factory...but you never know

later

Marky, it was caught and sorted at the time, with better attachment of the impeller, I know RYP did it under warranty for those early models that had the concern, some may have slipped thru the net but three years after the fact is a bit late for warranty.

Hi Ishy

Mine must have slipped thru

The cylinder bore looks fine with no 'blueing' or score marks so I guess I'm lucky, the new one wasn't very expensive so no big deal.

I'm guessing that the old 'broken' one would still pick up on the shaft now and again, and spin the water thru a little bit.

Big rush to get the mains bearings in and the motor back in the frame for all those trails over the xmas break :santa1:

I have found Sherco good at correcting things like this, instead of pretending the concern isn't there, they fix it as soon as they know about it.

It isn't just about having a good product, you also need good quality control and after sales service, or the punter just goes elsewhere next time.

Yeah - do you remember GasGas? Whatever happened to them? They made those disposable indoor bikes with the water bottle under the seat.

I am the worm that turned (2 weeks ago to Sherco)

Hey John, I tested my impeller last night :santawink: seems in fine fettle, hows yours doing.

Steady Ishy it's not his birthday until the end of the month. :santa1:

Here's mine, good un and bad un (sorry for the crap pic)

One less thing to worry about now I've got the plastic one

Sherco probably figured that most of these got changed while replacing seals.

Your's must be one of the last still in the bike.
