its quite easy to damage seals putting them in squuwiff and or backwards i would think this is more likely
very true, and its easy on that particular seal, from what i can remember.....
if its whacked in, it can enlarge the inner dia, also....
but check for grooves and the shaft size , incase
imo, a few parts on reliants dont have the correct seal to shaft fit, its only a few thou, but it causes leakage prematurely,
a lot of reliant parts are more hand produced than other cars etc, and suffer on tolerances,
(the input seal on the axle is a good example, its usually quite a few thou too small, and the seal goes early,
the metal its made out of is soft too, i put a speedy sleeve there , gives you the right diameter, fixes any grooves etc and its harder....)
