O-ring size for Tisco TS300

def38 · Oct 25, 2017

I'm going to remove and free up the TS300 diverter valve on my M-F 231.

It is stuck with paint and possibly corrosion. I'll want to be prepared with the correct replacement O-rings prior to forging ahead. I have searched for the parts but to no avail. Does anybody know the size(s) of the O-rings used on this valve? There seems to be no gasket between the valve and the mounting surface on the tractor, just o-rings. Help.

Thanks.
