Rebuilt or Repaired Gearbox Assemblies    
Somerford Mini Ltd. offers a gearbox rebuilding and repair service, courtesy of its workshop facility.  We can carry out repairs or rebuilds on late-model 
gearboxes, but can only realistically offer a repair service for the earlier designs because of, frankly, poor overall parts availability in the marketplace.  
Please contact us to discuss your Mini gearbox requirements - it would be helpful if you could supply us not only the details of what's gone wrong with
your gearbox, but the age (if known) and type (3 or 4 synchro, A or A Plus, gearchange type and driveshaft type).  The more you can provide us with, the 
better we can ascertain how we might possibly help you.    
         
It has to be said that at time of writing, spares availability for 1959-68 3 synchromesh gearboxes is not very good at all and unfortunately because of the 
high cost involved in reintroducing some components, the situation is unlikely to get much better in the forseeable future.  Rest assured, however, that 
we will always do whatever we can to help you.  The later 4 synchromesh gearboxes fare much better, especially of course the rod change variety which
were in production between 1973 and 2000.  Having said that, there are some surprising gaps in parts availability, even for 1980s rod change gearboxes.  
The general rule is that the older the gearbox type, the more components are not available new and the less likely a totally comprehensive rebuild will be 
possible.        
         
5 Speed Gearbox Assemblies    
5 speed rod-change gearboxes have generated much interest for some years now, with several organisations producing their own designs (Jack Knight Developments, KAD and Mini Spares, for example).  Please contact us to establish which are currently available.

Selector shaft oil seal failure was always a problem on rod gearchange Minis (as any late-model Mini owner with oil drips on their garage floor will know).  
The most common remedy effected by owners in the past was to put two oil seals one behind the other on the selector shaft (there's just enough space to 
do so), the outer one of the two acting both as a secondary seal and also as a secondary shield behind the gaiter, protecting the inner seal from under-body 
muck and grit.  Most importantly, the second seal helped to support the selector shaft and hold it in alignment in the gearbox casing.  Factory engineers 
finally came up with a remedy in 1985, fitting a modified selector shaft bush with a new O ring to improve the selector shaft alignment.  We of course 
supply all these parts separately, but we've also put them together as an easy-to-buy, easy-to-fit kit for the owner to modify a pre-1985 Mini or repair a 
later model.

The DAM3745 bearing with sleeve was intended to allow a post-1979 service gearbox to be fitted to a 1973-79 car, retaining the original idler and first motion shaft drive gears in that car.  Nowadays it makes a useful conversion part for those wanting to mix and match their gearbox, idler and drive gears.
