Slackdabber Posted September 2 Report Share Posted September 2 Just looking at a 199A Crank. No up and down movement in the big end but a lot of clearance side to side. Does this look normal? Link to comment Share on other sites More sharing options...
bullylover Posted September 2 Report Share Posted September 2 That is fine. The spacers on the gudgeon pin keep the conrod in the middle. 3 Link to comment Share on other sites More sharing options...
anotherclean Posted September 4 Report Share Posted September 4 Whenever I split a crank I always measure the width of the wheels so that I can be sure that the tolerance is the same when it goes back in, I have never seen that much clearance and would presume it needs pressing up a bit more. As Konrad observed he doesn't fiddle with antiques which is understandable as they often have unique measurements and need fiddling to get right. Good luck Link to comment Share on other sites More sharing options...
Trials-dabbler Posted September 4 Report Share Posted September 4 The service manual mentions 250cc - 360cc rod side clearance should be .022 - .024-inch (.55 - .60mm). Section 6 (16 pages) in the service manual is on rebuilding and alignment of the crankshaft. 1 1 Link to comment Share on other sites More sharing options...
