Gearbox Found!


Gearbox Adapting

So looks like a suitable ‘box has been found!

I’m going to use a Toyota T-18 5 speed. These are strong and feature an alloy case. Plus they’re great to service with a split case. Bearings will be replaced before final installation.

Had a bit of trouble finding one that had the shifter in the right place (so it wasn’t too far back) and that would accept a flywheel of 295mm (as I’m using the Rover one because it has the signals for the crank angle sensor.

Trialling different boxes (T18 5speed I’m using is in the middle and was chosen for the forward most position of the gear lever and flywheel capacity):

Dash and wiring / instruments removed (I’m going to fabricate a totally new dash from scratch):

So now I’ve measured and drawn (I’m a draftsman) an adaptor plate to be bolted to the engine and allow me to mount the gearbox.

My plan is to use the OEM Rover starter motor, but mounted on the engine side which will mean I’ll have to have it reversed by an auto electrician.
