Gearbox - how difficult a job

You Guys probably realise im new to mechanics due to the stupid questions..

 

However, learning quickly and once Ive seen a job done once I can do it again...

 

I was going to get my gearbox refurbed but you cant replace a couple of the gears and relatively expensive for the parts plus I would pay somebody to do it for me..

 

Theres a gearbox come up for sale near me with 30K on it for £445..

 

Would I be better taking this option? How hard is it to swap the gearbox? do you think it is something I can figure out as a novice??

 

Cheers

Can't really say if it's a better box or not bud, but swapping a gearbox is pretty straight forward.

 

I had never changed a box either but I managed to do my conversion on my own using just the info on here :)

 

Best of luck with it dude..

easy if you are changing gearbox for gearbox, and that its the correct box for your car (TT to TT or NA to NA)

 

Basically,

 

Battery disconnected

car in the air (Axel stands on all the 4 correct areas)

exhaust off, undo heat shield and tunnel brace

4 bolts on center prop, mark it with tippex across both sections to ease joining it back up later so you don't get vibration

2 bolts on center bearing and remove the front prop shaft

Undo the drain plug on bottom of the gearbox and drain oil into a suitable container

Support gearbox using trolley jack

6 bolts holding the read of the gearbox to the car, undo the gear stick linkage (1 bolt and a nut)

Unplug, disconnect the starter motor and remove out the way

2 bolts and remove the slave cylinder and move it out the way

then lower the gearbox at the back to make the engine tilt, start undoing the bolts holding it to the engine, once all bolts are undone (don't forget where the neg lead bolts to the gearbox)

Prise the gearbox away from the engine and lower on the trolley jack, then get under it and help it off the jack, should have enough room to pull the old gearbox out from under the car.

 

Fitting is a reversal

 

Handy tip, use the front of the prop shaft the plug the rear of the gear box to stop oil coming out.

Cheers Bud... might have a stab at it...

 

bud ill pm you my number, if you get stuck at any point give me a ring.

^^^^ Dont forget to remove your intake/intercooler hoses off the allow for the engine tilting back :)

 

Just have to undo one of the clips bud, let the engine pull it off once the clip is undone then when the engine goes back, plug um back in and do that one clip up, saves having to fiddle about getting it on both ends lol

yeah but you cheat, you have a 4 poster and most likely a trans jack so the engine doesnt lean back :lol: either that or you have been sending zeds out the door with poped intercooler pipes.:lol: (i know you wouldn't)

How long do you reckon it will take me?

 

4 poster in the garage, is that in case you work late and need a nap????:laugh:

If you drop the prop shaft centre support,

make a note of which bolt comes from which side,

I believe there are dedicated spacers/washers for correct positioning.

If you get stuck and i can get over i dont mind helping out. Just give us a shout.

Cheers Bud.. spoke to a couple of people and they think its expensive so might hold out...

Is the gearbox still in a car that can be driven mate? Or can the mileage be proven?

Who siad it was easy changing the gearbox?? Feck me.. couldnt get it lined up, had to tilt the engine...

 

The gearbox isnt as good as I thought. Somebody had bodged the starter motor bolts so had to fix, sensors broken and others..

 

bit gutted really. damaged my clutch and flywheel (only very slightly) as was tired and the replacement bolt was a bit long and tightened it onto them... daft mistake..

 

Love the feel of the shortshifter. havent driven it far as finished in the dark. definately took more than 3-4 hours.... lol...
