flexi coupling

[massa]

is it possible to put flexi coupling on wrong way round, i have had a squecking spelt that wrong anyway coming from that area, stripped everything down and coupling is marked it appears by the back of the hub , when coupling is turned round every thing looks better  ?  i noticed on flexi coupling screw holes for splined coupling on one side the threads start immediately on other side not so no threads are not to the end , they are recessed thanks again lads  dave

Hi Dave , I think that in theory it would be possible to fit the coupling the wrong way round but the outer case would have no thread to locate in on that side for the 4 mounting bolts. I would suspect that the spacer between the coupling and the inner race of the wheel bearing has been left out , seems to be a recurring problem here and a short term bodge job when replacing rear wheel bearings. It is all because of the "collapsable" spacer in the the bearing kit that requires special tools to get enough torque on the big nut.  [-/

thanks rusty if the flexi coupling is put on wrong way there is thread either end so 4 bolts would screw in i suppose, the threads either end of coupling on one side are slightly down shaft were as other end they are at top ?

I dug some bits out this morning plus had another look at various manuals. There is an extended shoulder on the inner section of the coupling that presses against the spacer I mentioned. So the four bolts mount into the holes where the thread starts part way down the holes. The main components , less the bearings & collapseable spacer , are shown in the picture. If the coupling is fitted the wrong way round then it would almost certainly rub on the bearing hub and/or the bearing seal  [-/

nice one rusty all was in place , the flexi coupling was wrong way round rubbing on casing thanks again  dave
