i can understand the smashed bottle of booze at the back of the bench, having disassembled and reassembled my box twice due to no 4th gear; very useful reference video none the less.

Thanks for nice video, I'm rebuilding Panther m75 1952 it has same gearbox.

The drive sprocket should be done to around 70 ft lb. A 52mm box spanner (Land Rover Axle size cheap on ebay) works a treat along with a chain whip to hols the gear. Simple. Always use a new lock nut on reassembly.

Agree - we need the build video

So you have to remove the main shaft to change the gearbox sprocket? What a pain! Do you know if this can be done without disassembling the whole thing?

Great video quality.

Ah! but can he put it together again?
