........ the confusing part for me is if it worked well as a spacer to exactly preload the bearings how come it works well when you re-assemble without it........ in the Chev MB C2 they talk about adjusting the bearing using ONLY the large external big nut that holds the brake drum... they make no mention of the "1193 spacer and shims"....... it seems to me that the internal cone bearing is held in place by the center piece of the brake drum....simialrly the outside cone bearing is held against the bearing race located at the outer edge of the 6 inch projecting hub and all is held tight, with preload by the large external nut when tightening the brake drum...... almost like a front axle circa 1970..... tighten so it is stiff to turn..... back off to the nearest cotter pin hole.... pin in place and test to see if it turns freely....

Always thought it was easy until I did my front bearing on a 1971 Pontiac Bonneville...... and snapped the front axle.... bearing too tight...... at 2 am on the TransCanada outside of Moncton.... what saved me was the snow storm I was driving in allowed to skid gracefully to the side of the road with the wheel tucked inside the front fender....Yeck
