Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Hints and tips whilst replacing kingpins/bearings

Sorry about that Arwyn but I did say in the first paragraph that these observations, discoveries and shortcuts did not form in any way a full guide to the job, which has been well documented elsewhere anyway.

Regarding the bearing cones, Cain replaced for me which did involve heating the hubs in an oven and freezing bearings overnight. As well as not having a press I didn't have the custom drifts so it was a no brainer for me.

He also pressed In/out the stub axle bushes (in very short order) and reamed them. Seems his Mulfab supplied hard chrome kingpins have fairly constant diameter so he just uses reamer pre-set to last bushes. First set he did were spot on but the reamer had been in his cold garage for a while before he was ready for second set. They came out just a tiny bit tighter so he put reamer on top of small radiator for a few minutes then gave them a second pass. Made me realise how critical this work is.

Timken matching taper roller set numbers if needed.



BTW I was looking at an old TM bearing adjustment thread involving a 2009 4/4 with stub axles being found to have two split pin holes at right angles to give better adjustment options. I cleaned my axles in a bath prior to painting and only found the one horizontal hole in each. Unlikely I would have missed one so wonder if later axles differed in this respect
