To do the frame alignment I needed empty cases so I stripped the engine and found zero crank end play. It was run at the lower limit but seems to have disappeared totally!
In addition to the high speed engine vibration I regularly felt what I can only describe as bearing rumble. Found the drive side bearing not as smooth as the timing side. I noticed there was some radial play with the crank in place in both bearings, ie with them dry the crank can be lifted 0.0015" measured at the centre of the flywheel. So 2 questions:
1. Is the play reasonable for 17000 mile bearings?
2. Is there a right and wrong way to install them? ie. smooth side of brass
cage facing crank or to outside.
Both bearings were from the original engine blowup so could they have got damaged from the hammering the crank gave them? Have done 10,000 miles since then. Crank is the same item and did not get bent and has minimal runout according to the guy who balanced last January.
Appreciate any help and opinions. Thanks.
