Is there anyway of changing the gearbox on a 300 tdi Disco without taking the engine out? As in how do you get to the top bolts of the bell housing?

discovery i presume?
use a long extension bar when you drop the rear end of the gearbox down a bit

Sorry forgot to say it was a Discovery
 

You did say it was a disco         just some people dont read 

Gearbox crossmember can be fun tho

On top:
1) Remove the center console stuff (cubby-box; rear-aircon pipes; etc)
2) Remove the rubber seal around the leavers, and the handbrake cable
3) Sling a rope around the box, with the support strand running up between the high/low/difflock lever and the front-prop drive-flange
4) support (lightly) from an engine crane or similar

Underneath
5) remove the gearbox crossmember
6) Remove clutch slave cylider
7) remove the bolts around the bottom half of the gearbox
lower the gearbox using the engine-crane/string/whatever (the whole engine/gearbox mass will tilt back on the engine mounts, until the back of the head is resting on the bulkhead)
9) remove all electrics & free handbrake cable from the body
10) undo the bolts round the top half  (and as piper5 says - you need 16"+ of extension bar to get the very top bolts)
11) pull back to release from the engine

"Assembly is the reverse of disassembly"
I confess I tend to leave out the top three bolts when I'm refitting 'boxes

Thanks for that, Pilot,

Don't suppose you fancy a holiday in Spain do you?

:laugh:

I reckon I can do a complete box-swap in a day these days (way too much practice).... but not in the heat of Spain ;-)

Can be done in under a couple of hours if you have a ramp ;-) depends on the age and rust factor though!
