trojan Posted October 9, 2014 Share Posted October 9, 2014 my 13/60 has oil leak timeing cover oil seal, after takeing it apart it looks like the pulley has done the damage to the oil seal there is a bit on it which is rough to the touch and if i emery cloth it away i dont think a new oil seal would seal it, and the timeing chain tensioner has two slots worn in it by the chain so i guess thats had it, is there anywhere i can get a replacement crankshaft pulley for a reasonable price its a spitfire engine the po has put in it FD endinginHE cheers billy Quote Link to comment Share on other sites More sharing options...
junkuser Posted October 9, 2014 Share Posted October 9, 2014 If there is damage on the part of the pulley body where the oils seal has been running, using a seal of a different design, preferably one with two sealing lips, will result in the lips running on an undamaged part.I don't have the part number of the double-lip seal I used but another member followed this advise recently, so a search may find the relevant posts.With the tensioner wear you describe it would be wise to check the sprockets and replace the chain as well.

Clive Posted October 9, 2014 Share Posted October 9, 2014 I would add that some modern replacement oil seals are much thinner than originals, they are recessed into the timing cover when fitted, unlike originals that sit flush (this is looking from inside)Getting a different seal to what is fitted may well move the seal point?

junkuser Posted October 9, 2014 Share Posted October 9, 2014 P.S. My reason for going to double lip seal was that the two seals I tried, that were supposed to be to original specification, would not seal satisfactorily on a perfectly undamaged pulley.Double lip overcame the problem.(Put grease between the lips {of the seal of course} when fitting or the outer one is likely to run dry) Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 9, 2014 Share Posted October 9, 2014 chris witor shows a double lip seal.some aftermarket seals are too thick and dont stay located in the cover especially the thick plastic bodied ones.the old oe tin body are better.Pete Quote Link to comment Share on other sites More sharing options...

nang Posted October 10, 2014 Share Posted October 10, 2014 Of course if all else fails you could fit a speedy sleeve on the pulley body.Tony. Quote Link to comment Share on other sites More sharing options...
