[QUOTE="peebeeaitch, post: 62643, member: 8318"] [U]27 Jan 2013[/U] I have spoken of the score lines. I decided that I should strip the other motor to see if the score lines were also present. Score lines: [IMG]http://bobcat.thesouthpole.co.za/BloodSweatAndTears/2013-01-27_ScoreLines.jpg[/IMG] The score lines are not present in the other motor. So, I am guessing that short of buying another motor, I will need to surface grind the bearing housing? Now, on to another point. The manual is great at describing the explosion of the motor.
