I have a pair of R&M LJT1 angular contact bearings that fit in the separate housing of a D-Type back axle. I have fitted them with the 'thrust' engraved faces together. Is that correct?
Tony Press published a 'How To' article about these stating that using standard LJT1 bearings in a later D-Type back axle would result in the pinion moving forward by 1/32" unless one carried out some machining. He stated as an alternative there were special versions of these bearings made with a reduced width outer race on the non-thrust side.
I do not understand why the bearing outer race width could cause this problem or be alleviated by reduced width so maybe someone can explain that?
My LTJ1 bearings do have the reduced width outer race on the non-thrust side so I guess I am ok with those although I cannot see any markings to say they are not standard bearings.
