can i change a gearbox

tuborg_man

I have a 1.4 seat cordoba that's gearbox has gone bust. (Have another car and it isn't worth much soit's a good car to learn on)
I have being doing my own servicing and fixing basic problems before but i want to get a bit of practice in the harder job's to do.

My question is can I manage it, is it justa case of unbolting it from the crossmember and detactching the driveshaft's and the linkage's,
Could i reuse the clutch or would it be pretty useless and does anyone have any hints or advice,
Thanks a million,

That's starting at the top then! First thing would be to get a Haynes manual and see what you are getting into.

If you bear in mind that you might end up with a big unfixable mess and that gearboxes weigh an awful lot and you might end up shearing bolts on an old engine (been there, done that, wished I hadn't) then go nuts! Don't drop it on your foot and tell us how you get on

Edit: I'll add that I've disassembled and reassembled a gearbox on the bench, requires organisation and discipline but that's all really. I've never replaced one in a car so I'm in no position to talk. But I don't think a mechanic would tackle one without a ramp. Or on his own.

Out of curiousity I asked:

You will need to drain the oil from the box, remove the battery and tray, air filter, starter motor, speedo, reverse light switch and any other conns like earth straps and manifold brackets. Remove driveshafts, gear linkages and the engine mounts.

You'll need a good set of spanners and sockets, jacks and axle stands. And a ball joint splitter I think. Plus a burly friend or two and if married, a really understanding wife.

Take pictures and if going to hospital, move country first. Some help I am!

ok cheers thanks for that, ye i've had a good look under at it, gear linkage is easy enough to get at, as is the driveshafts and where it's bolted to the crossmember of the chassis, speedo is also easy to get to, bit worried about a few things but i'll go have a look at a manual and see how i go from there,
car when running right wasn't worth to much so at least there's no massive financial drain if it goes belly up

two wheels good

A trolley jack to support the box as it comes away would help.
Support for the engine is reqd to so as not to strain the mountings. A second trolley jack or even a scissors jack would do
If you want to strip the clutch mark the components so that they go back in the same position. The components are balanced - AFAIK

Just to add if u take your time and watch everything.anybody can strip things down but it takes the good mechanic years to get experience to get the know how when reassembling things to prevent accidents further down the line and how to get things right first time.
