You can never clean a motor enough. When motors are machined the crud goes everywhere inside.
And don't listen to guys that tell you that you have to check your bearing clearance with plastigauge. mic's are the only real accurate way. Plastiguage is verys to much. I do my own work and all I have are a good set of mics', feeler guages, venier calipers, degree wheel and dial indicator.
