Thwaites dumper gearbox identification / parts.

[Edenboy]

I'm quite familiar with many dumper gearboxes i.e 40M, 85M and JCB type torque converter. I've recently took a manual gearbox out of an early Thwaites 4-5 ton dumper which has this Newage gearbox I don't recognise. I've attached a picture of the ID plate but get nothing on Google. Any ideas?

What's wrong with it ?? and what sort of age is it

Two gears have shredded. Probably late 80’s.

Is it a gearbox with a manual forward/reverse shuttle?

Yes thats the one.

Ok its not good news then. There is a shaft or gear set that is a common fail. Parts for the gearbox are not available as far as i know. They would be late 70s to early 80s. Most of these are 4 speed but there are some 5 speed. If your dumper has a ford engine i am told it is possible to fit a ford cargo gearbox but only 1 reverse gear then.

Thanks very much for the info. Think ive found a 4 speed Cargo box which will work 👍
