The Girling clutch slave cylinder on my CJ5, 1981 with the AMC 150
four-banger engine is Jeep Part #52000070. Inside the cylinder ther are only
two parts, a metal pison and a rubber seal that follows the piston in and
out. I want just the rubber seal that goes on the piston but can not find
one anywhere. I dont want to pay $70 for a new unit as the bore and piston
is in fine shape. Only the rubber seal is worn.
Can anyone direct me to a source for this seal   OR
if its not available is there any treatment I can give the rubber to swell
it or such? I have tried silicone paste but that had no effect. The leak is
sligh. Needs bleeding every week or two.
