Gearbox gear lever cap bolt

Recommended Posts

The long bolt passing through the gear lever cap (3.5"× 1/4 unf), part BH604281 in the Moss book, is worn along its length, and may be contributing to gear lever rattle/vibration.

I think the standard replacement bolt is not especially hard, and will wear fairly quickly. Has anybody else had this issue, and maybe sourced a higher grade bolt?

Thanks

Or just get another one. 

They seem to last a few decades.

Hi Mike, the gear lever may be vibrating but it won't be the source only the result. I would start by checking the propshaft as that is the closest component which could cause vibration, has it been Ballanced recently and are the UJs ok?.

Have you got the spring & plunger fitted to the bottom of the gear lever ?

60 yr old ones are usually still Ok so I wouldnt have thought that would be a problem, as Bob says more likely the pin and spring has gone walkabouts. https://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/clutch-transmission-drivetrain/gearboxes-components/gearboxes-external-components-tr2-4a.html

Thanks everybody.

 I think I will stick to a standard bolt, but replace the worn one.

Yes, I do have the plunger and spring, and plenty of grease. The large tapered spring under the cap (Item 11 on the Moss page )seems OK, but in any case new ones are nca.

The propshaft is fairly new (30,000 miles), but I will get it checked and report back.

One other thing is do you have the big spring the right way up?

These springs are not that difficult to find : I've just fitted one to a TR5 this morning, taken from a 2000 saloon.

Hi Chris,

Presumably the 2000 saloon 'box is therefore no longer useable?

I suppose it would not be too tricky to make one.

The spring size changed in 1973 ish the smaller hole diameter got bigger and this does not tension the stick into place.
