Engine and/or gearbox changes in IIa (etc)

**Slunnie** · 23rd January 2012, 01:40 PM

Hi all, sorry if this has done the rounds.... many times, though I couldn't see it (perhaps I should see an optomitrist... ironically).

Engine and gearbox changes to a series - I've always done these with the body off. A new challenge for me may shortly be to do one with the body on!

I have a IIa 6cyl ute. Gearbox is dead. Engine might also need replacing.

Can I just confirm the following:

Engine change only - Just split the gearbox and pull the engine?

Engine and gearbox - Will the gearbox slip out from under the firewall with the motor or does this need to be split off the motor and dropped through the chassis, or pulled up through the cabin - an if so does the seat box need to come out?

Gearbox only - Likewise, will this drop through the chassis, or will does it need to go through the cabin - and if so does the seat box need to come out.

Thanks for this.

Edit: This is the ol' girl!

Bearing in mind I have only done this on a 4cyl...

Engine removal: split engine after removing rad and bonnet, engine can be lifted out fairly easily.

Gearbox: Up through floor after removing floor/tunnel/seat box. That was until I fabricated a removeable gearbox crossmember.

Thanks for this!

Do you know if the motor and gearbox both come out (looking like it will happen this way) if the gearbox will come out through the engine bay also?

Ahhhhh, actually thinking back to when we pulled the spare engine/gearbox, we had to lift the firewall...... hmmmm. Thanks for this.

As an addendum, remember that it is possible to disconnect the transfer case from the gearbox in the vehicle - I suspect with it disconnected, you can remove the engine plus gearbox, although I have never done it, and it is then probably possible to remove the transfer case without removing the seat box, but again, I have never done it!

if you drop the Tcase off and the shifter then yes you can pull the gearbox out with it still on the back of the engine, if the radiator bulkhead is removed it actually balances pretty nicely with the COG about inline with the last bolt in the rocker cover.

If you don't want to remove the seat box, it's possible to separate the gearbox and transfer case and then drop each out below the vehicle. It's a wrestle to get the gearbox out, but possible.

I have never done it in one piece. However you would need to remove the t-case and rad support as mentioned. You would also need access under the middle seat to help unbolt everything before splitting t-case.

Jeez there are some brilliant minds on here!

Thank you all very much for this, it sounds like splitting the transfer off and then sliding the lot out will be a lot easier for the full R&R than the other options. The seatbox is a pain to do and I'd probably almost be better just lifting the entire cab for the ute.

Hopefully I'll come back grinning rather than recovering from a dose of tourettes.

I have seatbox removal and Tcase removal (once the shafts are off) down to about 20 minutes each..

Er, I mean that I dropped the transfer case out and then....maybe I somehow upended the gearbox and lifted it up and out, forward of the seat box. Or maybe I didn't. Can't remember. Either way it came out, I definitely did it.....

I guess if you tried it, the Landy would show you how it wanted it done.
