DIY Gearbox refurb
Padstar - 15/5/12 at 06:00 PM

Is this a good idea or is it best left to the pros? I want a fully refurbished box not just a cleaned down used unit. They don't seem that expensive to buy refurbished by professionals, but where is the fun in that.

Is any specialist equipment required to get one looking spiffing in my own garage and is there a manual that gives instructions on how to go about it anywhere (or good websites)?

With a bit of common sense and a methodical approach, it's fairly straight forward. A workshop manual can help though. I'm a bit like you...why pay for someone else to do it you can do it yourself!.

Which box are you looking rebuilding?.

Type 9 or an MT75 to suit a ford engine build. Are there manuals specifically for refurbishing gear boxes?

An old Haynes manual for the 2.8 capri, sierra etc covers the type 9, and they're pretty straight forward. The only odd thing you need is a 36mm socket to get the 5th gear nut off the layshaft, and that's a bit bigger than most socket sets go up to.

Can't comment on the mt75 as i haven't pulled one in bits, but gearboxes aren't rocket science!.

I've not checked this thoroughly but when I got my MT75 I did do some research and it looked as though refurbishing it at home isn't feasible. (I believe the Haynes manual also states this as special equipment is required though how special I don't know).

type 9 are quite simple,the MT75 need a few special tools that aint cheap

The Type 9 rebuild is covered extensively in the Haynes gearbox book, (AUTOMOTIVE GEARBOX OVERHAUL MANUAL), (along with several other boxes). The MT75 though is not covered, although it is quite possable to rebuild them. You do need some "special" tools, but if you are a bit handy you can infact make them yourself. There is a rebuild an MT75 post on the "Ford Power" forum which is easy to follow, plus it shows how to get over the "special" tools needed, as well as how to fit a better ratio first gear. HTH Ray
