I am kind of confused on how to measure thrust bearing clearance. So if you can get your .0025 clearance on the thrust bearing but you cannot get your .0030-.010 then you have to sand away the thrust bearing right? now do you measure your clearance with the crank pryed all the way forward? Books are kind of vague.

 

no manual here at work but i believe the thrust clearance is more in the .015 to .020 range, lot more than you said. put an indicator on the crank snout where the dampner goes and the crank rearward and zero the indicator then pry the crank forward and note the reading. i guess you could do it with feeler gage too, but i never have.

 

You're not ever supposed to sand on a bearing, not for any reason.

To measure thrust clearance, pry the crank all the way forward, then all the way rearward. The thrust clearance is how far the crank moves. .015" is typical for a new crank, .020" or more is typical for a reground one.

See your other post for more info.

 

what i meant by sanding is the thrust surface not the bearing surface that mates with the crank and yes you can do that. But I found my problem it is in the post of squealing. Very interesting. Thanks.
