Re: Piston top groove

Looks good on there mate, What size is the mechanical seal in the water pump, I still have one or two from my days as a catering engineer, I think they are 19mm 22mm O D ceramic, shaft size was about 1/2" I think.

Re: Piston top groove

You are probably right with those dimensions John! But I didn't measure anything when I stripped it, so relying on John Walker and his engineer. Cheers Ron
