3 Speed Gearbox Jumping Out of top

[D Johnson]

A friend has a 1929 OHC morris with a 3 speed box that keeps jumping out of top.

Is this a common problem if so does any know of a fix

Thanks

Hello David,

I haven't experienced this problem myself - but I'd suspect perhaps worn selector ball springs or badly worn teeth? Is this one of Brian's tourers? Does it feel at all sloppy when selecting top?

The only problem I have ever had with a Minor box is it locking up when allowed to roll backwards when first gear is selected. Don't ask me how this happens, but I spent an embarrassing few moments at a green traffic light years ago - and rocking the car forward and back is the only way to free things up.

I now have a four speed box in my 1933 sv two seater. This jumps out of third gear when 'driven' and fouth on over-run, i.e. when approaching a roundabout and you take your foot of the accelerator. When going uphill fast in third gear I keep the gear lever in gear with my hand (not difficult and I am now used to it). What caused this I do not know. I did restore (rebuild) the gear box But I am no expert and just cleaned everything and put it all back together. I do not remember if I had this problem 6 years ago when I purchased the Minor. Then I did not realise one had to use third so much when climping hill and used to struggle up in forth!!. There must be a reason for this jumping out of gear - come on chaps - answers please.

Maybe the end of the gear lever has worn, and the square 'lump' needs building back up again to get slightly more 'travel' when selecting gears.........

I have this morning sold my 2 seater to a member of my Golf Club. Never even drove it!! When I drove him round the block I told him to hold the gear lever when going up hill in third gear. He did not mind. Thanks everyone for your help in the past. Will have a few spares to sell - dynamo, starter, carb and manifold etc. Highlander.
