Re: 1939 Gearbox: Disassembly of main Shaft: A Cautionary Tale

Hi, all who read this,

We found the problem with the main shaft was a replacement shaft (not factory - not sure whose, perhaps Max Merrits), where a new shaft & gears had been very well made & machined: However, second gear was screwed & spot ended onto the top shaft, with brass bushes. (I have no idea where I got it from)
The weld had come undone resulting in second gear unscrewing itself & the car selected two gears simultaneously with rather disastrous results.

We have made up the necessary gear to press fir the collar as in the original factory top shaft: the roller bearings & other minor parts came from Max Merritt, so we now hopefully have a New "As From Factory" top shaft.

I'd caution against using the other style shaft which can come undone

If you use your car at all, rebuild it as the factory did.

The other will probably fail!
