Anyway, yesterday I dived in and removed the top cover of the gearbox, in a bid to find out why top gear went AWOL on the return from a recent pub meeting. This also required the removal of the handbrake assembly, fortunately once the floorboards have been lifted the access is very good.

As I suspected, the pin that secures top gear on its shaft had broken/dropped out, allowing the gear to slide up and down the shaft, away from the gear it should engage with.

The high speed gear in the centre, used when top is selected, also doubles as the speedo drive so should be in a fixed position at all times. The red arrows show where it should be pinned in place.



I fished out a piece of the original pin with a magnetic pick-up tool, once the oil had been drained off. I found a few small metal filings in the oil. Unfortunately, there isn't a lower pan that can be removed from the 'box, so all I can do is fish out what I can from above, and hope that the rest has found its way through the drain plug (I've yet to check all the oil that came out).

Next is to decide on a suitable method of pinning the gear back in place. There's not a great deal of load on the high speed gear.

I adapted a pin to fit and popped it into place over the weekend. The box was treated to a fresh quota of Transoil 250 lubricant. This evening I re-installed the top cover; getting the selectors to re-engage wasn't as bad as I thought it'd be, but the temperature in the garage this evening made working out there not all that pleasant.

With the engine running and the back axle in the air on stands, I was able to go through the gears and things appear to be working once more.

The floor needs to go back in, then I'll take it for a run down the road and see what happens.

Sorry I missed your request for help removing the top but it looks like that went O.K.

How did you fit the pin to stop it coming out?

In the end I opted to go non-original with the pin. I found a large oversize, old-stock, split pin. Gentle filing and a lot of trial and error saw it reduced just enough to fit in comfortably. The pin isn't under any great strain that I can see, given that the gears rely on the castellations in the shaft for shear.

With the small access panel removed from the top of the 'box, I can just about see the pin, so it should be possible to keep an eye on it. A test run out today for a few miles was completed successfully, I'll monitor things and do a few more runs and see how it goes.

A few more test runs have been completed, latest being this evening.

Dad (in his Traveller) and me (in little Dodge) met up for a shandy in town, we picked a pub that had a collector/classic club meet taking place. As it happened, we - non-members - were the only ones to turn up in something old - everyone else it seems had turned up in modern-ish cars, maybe the oldies descended after we'd departed?. As it was it didn't matter, I didn't want to stick around long as I wanted to get back before it got properly dark, so left after an hour or so.

Splendid....I have noted a tendency for these old motor meets to have fewer proper old motors too...so now I don't bother......Sometimes I even think I've got the 'wrong night'....

Being August there may well have been people away on holiday, depleting numbers, but I'd taken my camera thinking there may have been one or two things in the car park to take a snap of.

Or when I go off-roading!

You'll note the tinted upper screen, I assume someone in Australia decided it'd help with the bright sunshine. Not so much of an issue here Smile
