As i am going to be getting a refurbished gearbox soon i was was wondering how hard it is for a novice to remove the gearbox and then put the new one back onto it. I have looked at the haynes manual and it doesnt give that much detail on it. Also i was wondering what tools are needed to remove the gearbox and refit it.

Thanks for your help.

Hey dude

Its not so much of a case of removing the gearbox, as removing the power unit, splitting the engine from the 'box, then fitting the new box.

Its not *hard* as such, but there's many things you need to get right first time, as there is no room for error with things such as seals, gears etc.

Basically, drain the fluids, remove the engine, remove the flywheel cover and flywheel/clutch assy complete, remove the transfer gear cover, split the engine and box, clean gasket surfaces, refit box' to engine with new gaskets, 'o' ring and 'u' seal, refit transfer gear cover with new crank seal and gasket, refit flywheel assy, refit flywheel cover, refit engine, plumb up, job done.

Make sure the gearboxes are compatible (ie both A or A+, both rod change or remote etc), and I would definitely fit a new oil pump into the engine, no matter how good your oil pressure, for the £15-odd its well worth the piece of mind.

If there's anything more detailed then just ask, but if you're going to ask things like 'whats the flywheel and how does it come off', then I really wouldn't consider doing the job - it might sound a bit harsh but the last thing you want is to get halfway through the job and get stuck, and end up with a dead car till you get it sorted.

Hope thats of some help!

Sounds easy enough really, will have to get some things first. Was going to change the clutch and oil pump anyway, just need a flywheel puller and ill be fine.

Thanks.

Instead of trying to lift the block onto the box, turn the block upside down and but the box on it that way - loads easier. Make sure you put the block on something clean that won't damage the face like a big of wood board.

Using an engine stand it's a piece of piddle...

but yes much easier to put the box on the block, unless you have a hoist which you can lower it down onto the box..

did this the week before the showdown. it took a day to separate the old box and fit the new one and get it all ready for fitting to the car....i did take my time tho, and ensured everything was right. take pictures if you have a digital camera, and make a check list, to save you thumbing through your haynes comic for torque settings

May invest an engine stand then as i dont have one, dont have a hoist either :S o well ill sort things out.
