Upgrading to taper roller wheel bearings on front axle of the 1275 MG Midget

In this episode we fit the new tapered roller bearings to the front axles as an upgrade over the standard wheel bearings for our 1973 MkIII MG Midget.
Taper roller bearing kit for MG Midget is an upgrade over the standard front hub bearings which are angular contact ball bearing type. These original bearings work well but does not allow for any adjustment as the bearings wear. Taper bearings provide better support for fast road and competition applications. The kit utilizes the standard bearing spacer for a simpler installation.
We fit the bearing shells to the hub using a hammer and drift; which is how to do this if you don’t have access to a press and a suitably sized socket etc. to press the bearing shells into position.
After a dry fit we measure and set the end float in the front axle to between 0.002 and 0.004 of an inch in a similar way that the MGB front hubs are set with their taper bearings. We discover our dial gauge doesn’t quite have the accuracy we are needing (we ended up borrowing a more accurate gauge to check and seemed to be ok at 4 thousands of an inch).
Once the end float is set we pack the bearings and assemble the hub to the axle; not forgetting to fit either the dust shield or the new brake disk.

Timeless video I have a bugye with the same setup. My brake system is with the mgb calipers and spitfire rotors. It's not a simple bolt on, but after working out some issues, I'm happy

I’d like better brakes but would need to check the rules for the historic class I enter competition in. Not bad with the servo assist but would be good to have more longevity before getting too hot.

Today I had to remove and refit the hub on my '78 Midget to replace a broken wheel stud, this video helped me a lot, thanks Jerry. Look forward to some more vids on the Midget.

Thanks for the Feedback Lee. I hope to get some more garage time and complete the repairs / upgrades to the other side.

When pushing in the outer bearing ring WITHOUT a press, I use the OLD ring to protect the new one

Ray, that is a great tip, thank you. Seems so obvious now you’ve said it. Will try that technique on the other side if I ever get some garage time.

I froze the race to aid in seating.

That’s a good idea to make life easier. I did consider heating the hub.

Trying to replace my front bearing with tapered roller bearings, but when I put in the new races, the front one all the way seated could be spun in place by hand. Any suggestions on how to fix this without buying a new hub?

Oh that's not an easy one. Are the new bearings too small (relative to spec) / same as old ones? If they differ from the old ones you could have a badly machined bearing. If it is the same size as the old all I can think of is that the bearing has been loose previously. Whilst you can rotate it by hand, does it feel loose in the hub (i.e. up and down / side to side)? How easy is it to move? It might be snug enough to torque up and not be an issue, but as I'm not a mechanic by trade, and I haven't seen it for myself, I'm not really going to be offer you your best solution. Sorry; I suggest you ask a local garage for their thoughts perhaps? Good luck.

@@JerryMotorsport I got them from Moss Motors that are supposed to work for 1972 MG Midgets w/Wire wheels - kit part# 125-822. Not sure the size - but I have tried both of them in the kit and they both can be moved by hand - spin and up and down and feel about the same looseness. I will have to search and see what size they are supposed to be. Thanks for the help and I will let you know what I do and the suggestions I get.

I used a punch around the inner surface of the hub surface and used loctite bearing surface 660. Worked great.
