Was asked some questions today about fitting this seal, as someones just done it and its still leaking.
1) They unsure if there is supposed to only be the one seal at flywheel end of crank?
2) Is there such a thing as on "oversized" oil seal, so it makes a tighter seal on crankshaft?

I've always been lucky and never had to strip a Reliant engine yet so don't know the answers...anyone know?

speedy sleeves the answer if you cant get a tighter seal,,,
the shaft may have a groove in it, it,l fix it, permanent,




or

try asking for dennis in the stores at michaels of selby , he knows EVERYTHING  about reliants,
he is a reliant god

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....)

I speedy sleeved mine,and took great care in fitting it etc,but it still leaked! Gave up and left it in the end!

I ended up making up a rubber sleeve over the prop/axle flange on one of my trikes to catch the drips!

Good idea that! As Fifer said  a while back,its an old design engine that may never have a perfect seal.

Thanks for your input guys, however it turned out there is a small crack in the crankcase and thats where the oils coming from. Mate recons he can tig it up easy enough.
