furse Posted January 29, 2016 Report Share Posted January 29, 2016 Can anyone tell me where this washer should be? Took the sump filter off today and it was lying in the bottom, it's about 22mm diameter Quote Link to comment Share on other sites More sharing options...

denbee Posted January 31, 2016 Report Share Posted January 31, 2016 I agree with aawil it looks like the flange of end of camshaft bush, and looking at the lip around outside it as been going round in the crankcase ? Quote Link to comment Share on other sites More sharing options...
charlie prescott Posted January 31, 2016 Report Share Posted January 31, 2016 Hi Guy's. Hi Furze . I did not want to jump in with both feet untilI had thought about it. And I also think it has come from the camshaft bush, If you go to my site and look at the "Duplicated C15F engine" page you will see that I had the same problem. Through lack of lubrication to the camshaft, the bush sticks to it and uses the crankcase as the bearing, This makes the camshaft hole in the crankcase bigger and the only cure is to turn up an oversize bush for the camshaft to run in. It is not that difficult if you have the use, or someone who has a lathe. Regards Charlie. 2 Quote Link to comment Share on other sites More sharing options...
furse Posted February 12, 2016 Author Report Share Posted February 12, 2016 Stripped the engine now and I think you guys are right, but the bush is not loose in the crankcase, and doesn't look like it has been turning, crank hasn't been rubbing on it, but have noticed oil feed hole doesn't line up.

furse Posted February 12, 2016 Author Report Share Posted February 12, 2016 Just had another look and the flange to this bush is on the timing side, not crank side, also although bits are distorted it's too big in diameter to be from that bush!!

aawil Posted February 14, 2016 Report Share Posted February 14, 2016 hi furse just a thought on some sump plates bsa used the perforated metal strainer had a brass washer riveted on where the pick up pipe goes through ,whip the 4 bolts off and check that ,, will Quote Link to comment Share on other sites More sharing options...
furse Posted February 14, 2016 Author Report Share Posted February 14, 2016 Hi Will, that's where I found the bits, much bigger than the brass washer in the strainer, puzzled me where it has come from. Can't think where or what is was to end up in the sump ? Quote Link to comment Share on other sites More sharing options...

norman_wisdom Posted February 16, 2016 Report Share Posted February 16, 2016 Hi Furse, Don't forget the 'cockup' theory....in this case that's the possibility (feint I know) that this was never intended or meant to be in there in the first place...crankcase sat under a bench for years and this little fella just fell in..... Do you know the history of the bottom end? Quote Link to comment Share on other sites More sharing options...
furse Posted February 16, 2016 Author Report Share Posted February 16, 2016 It is suppose to be a new rod along with all bearings etc Quote Link to comment Share on other sites More sharing options...
