Still for me I would certainly like to know what grade of steel tubing they use for the crush tube as this will play a major part in keeping the end float at its original setting? By the way your work friend described another way that I was used to in setting up this type of bearing. We always used Shell Retinex but I cannot remember the grade ,as there is grease and grease, remember clutch bearings!. This might also be an area worth exploring?
Taking your point; was it assembled dry/? Reading my Brown Book para18, it could be interpreted that the bearing race is not packed with grease but only the housing at 1/2 full?
