Tractor gearbox rebuild

[tcfengineering]

Hello, I have an International 956XL with a knackered gearbox. Wondering if anyone has ever done a complete strip and rebuild on a simple tractor gearbox. I have never been inside one and I am wondering how daunting it is. Rebuilt plenty of engines and diffs, but never a gearbox. I have the workshop manual, a clean workshop and lots of tools.

 

Any advise either way would be appreciated

Cheers

Cant comment on complexity but Im sure whilst your in there its best to do the handbrake band at the same time! cab off job if that goes so might be best stick a fresh one in if worn.

 

Whats gearbox done or not doing? hope no shite gone to hyd pump etc

Funnily enough I was expecting the handbrake to be in lots of small bits in the bottom but it looks like new. One of the main bearings in the gearbox is shot, so it is making nasty noises when you turn it. Will have to see what else is knackered, thats why it needs pulling apart.

 

I think I am tempted to have a go and just take my time. Usually with these jobs, you dread it and then once you get on with it, you think what was all the fuss about. At least then I will learn how to do it.

One thing aswell is condition of clutch.... If you do change you have to have surface of flywheel machined and the same removed off the mounting part. 

 

Like you say could be a simple job. It's just time and if you can afford it to be down in bits / only machine.

 

I usually fall into the last category of only machine and can't afford it down long. 

 

One thing I have learnt though is that sometimes it's just easier to do things yourself as the workman ship of some out there is shocking! No good agri mechanics about here

Have a look at this to give you a brief look at what's in front of you. 

 

Foreign video and crappy music but I'm sure some will be relevant

Mine looks just like that one in the video, only a lot more oily !

 

I am the same as you, I just dont trust a lot of people to do a job like this right. I am not bothered if it takes a while I have got other tractors and a Unimog.

 

I think I will have a go, first job clean everything !
