450F Water Pump Woes

For all you Dub Yar 4 poke owners, keep an eye on where the water pump impeller shaft, plugs into the counter balancer. Over time the ovalish shape wears out, and stops turning your water pump. As you could guess, that will end with nothing good.

So for Timo, the motor is on the bench, ready to split the cases tonight, and RMATV will deliver my $300 worth of parts on Wednesday.

It's part number 9 if anyone cares.

I'm thinking it might be a problem for the YZ also. Of coarse, not your YZ's.

The sale was a zoo, but stuff was too cheap.
