1,500 miles back I did a complete engine rebuild of my Comet- that included new everything except for cases, conrod and flywheels. Up to then I had covered almost 5,000 miles and the primary case oil was always clean.
Now, 1,500 miles after the rebuild I have discovered that the primary chain case oil (it is actually ATF) is dirty with speckles of steel (its attracted to a magnet) in it. There is a seal on the mainshaft into the primary chain case and the oil in the sump and UFM is pristine and clear.
Now - I suspect that with the rebuild the lateral position of the mainshaft on the drive side may be different than before resulting in some misalignment of the ESA and the clutch basket sprocket and thus the metal chards.
I have some ideas on how to check - and fix - the misalignment of the primary drive chain though I have never actually done it so I wonder has anyone come across this before and what is the correct and/or proper way to check and fix misalignment in this area?
