Talk Morgan Forums Community Vehicle Talk (non-Morgan) Gearbox Swap.. !

There is one positive from being under house arrest.. I can get some jobs done!

My MG decided to dismantle its 3rd and 4th Gear Hub whilst it was still in the gearbox and being used! Out with the gear oil came 3 springs and some ball bearings..

The TC gearbox is normally very robust, the TC racers use them, but the gearing does prevent relaxed driving in modern traffic. In top gear at much above 50mph the engine is revving quite a bit. So one way to help this is to fit a 5 speed gearbox to reduce engine revs and so improve its longevity and make for a much more relaxed drive.

So this is what i went for.. it took me just one day to strip out, i decided to take it out via the cockpit rather than engine out. If there is a next time I think i'd opt for the latter, its less work. It was also quite a feat as i only have a single garage and cant open up the car doors fully.. much swearing took place!

Rebuilding it took me 4 days of work, but it was well worth it..makes a huge difference..

Anyway, i thought some of you may be interested so here's some pics.. first the old box in situ but partly stripped:



The 5 speed fitted:



And finally all back together! Gearlever still in same place.
