gearbox mainshaft

[keith douglas]

Ladies and Gents, I have a good second-hand mainshaft from an early TD gearbox to replace the damaged one from my TF. (Sorry this is not strictly a tabc question) The replacement is missing the keyway for the speedo drive but more importantly also the indent that allows the ball in the 3/4th sliding hub to locate this hub centrally on the splines. As this modification was made early in the life of the box I guess the tendency of the hub to float between the two cones was causing excessive wear of the brass synchromesh rings. I don't therefore want to use the shaft as it is. So can anyone recommend a person or company in the UK with the expertise necessary to drill or otherwise machine the exceptionally hard surface of the shaft? regards, Keith Douglas.

Keith, Brian Cherrington at BM Auto Equipment Ltd offers a gearbox rebuilding service for the Riley RM models, so he might well be able to help. Contact phone/fax is 0121 308 2354 or mobile 07973 749 608. Alternatively, I have always found Barrie Dean (Triple-M man) to be very helpful, with lots of contacts. Tel: 0115 920 8416 - mention my name and he'll charge you twice as much! By the way, have you got the video on rebuilding the TD/TF Gearbox featuring T Register Technical Adviser Barrie Jones (obtainable from me at 15 plus 1 postage) and Barrie's new book entitled "Barrie's Notes" and sub titled "Maintaining a 1955 MG TF in the 21st Century" (obtainable from me at 6 plus 1 postage)? The book is full of technical information, including a section on strip down and rebuild of the gearbox.
