Re: Kohler K321 rebuild questions
You have to have some clearance between the balls and the races for the oil film, when the motor is running and the bearings are full of oil it takes up the clearance. This is the same concept as journal bearings and why they need clearance.
Allis Chalmers B-12: Front, center, and rear PTO; Hydraulic lift; Two-speed pulley; Front and rear work lights; Rear stinger and doughnut weights; and Bolens outer cast wheel weights w/ Cub Cadet cast inner weights
Still needed: Right hand lift, ball hitch, sleeve hitch, and front counterweight.
