I have an old Merc 407d camper van, the engine has died and it has been sat in a field for quite some time, various small animals have spent more time sleeping in it than I have and I either need to do something with it or get rid.
I would like to put a more up to date merc engine and gearbox in but I don't have the money.
I have a spare Land Rover 200tdi engine so I think this is my best option, I know and like these engines. So the next question is which gearbox? I have a disco box which I think is an LT77, but there is no point fitting this as it would have to be converted to 2 wheel drive, which is pretty pointless.
I know other rear wheel drive/two wheel drive Rovers an others Leyland vehicles used an LT77, but did these vary?
If so which would be best to go for?
Do they all have the same bell housing?
Thanks in advance

It was a 2.4 4 cylinder. Which I took out and someone stole it, it was knackered anyway but had some good new parts on it that I could have sold.

I don't know if it would fit, or how much you want to spend. But I've got a merc om606 lump floating about here, 137hp non turbo.

LT77 was used behind the V8 SD1 and IIRC Peugot lumps in Sherpa vans. They're the 'heaviest' I can think of. It was first found in the TR7

A 6 cylinder engine wont fit without chopping into the cab, I would still need to find a suitable gearbox as well as the 407 one is geared very low. Cheers for the offer though. |

Is it not just a case of taking the transfer box off leaving you with an LT77?

The latest development is the R380, mid '90's on, externally almost identical to the LT77. I had a picture but I can't find it right now, where I'd fitted a Land Rover 200tdi bellhousing to a rwd LT77 for a mate for him to put on his 200tdi. Was a simple case of removing the rwd type clutch pivot pin, swapping the bellhousing over, and making a spigot bush to suit. |

Yes, essentially the same gearbox, except the clutch pivot pin sits in a different place for the rwd and 4wd types, I can't remember if the release arm is the same, compatable or different. My spare clutch arm parts had all got mixed up and I don't know exactly which one come from where. |

The R380 is certainly a much stronger box than the LT77.

Looking at the various box types I think the Land Rover position of the gear stick is probably reasonably close to the original. The rear wheel drive boxes put it a long way back, possibly to the extent that it is not suitable. Any ideas?

Have you looked at the Sherpa/LDV type gearlever? Apart from that it is a case of being creative or a big bendy magic wand.
Fitting the Land Rover type gearlever stuff to a rwd gearbox won't work without extensive re-construction of the rear casing, do-able I reckon, but not easy in any way.

Hi, I would advise against using a Land Rover g/box because the mainshaft out the back of the box is a different length and configuration to fit a 2 wheel drive tailhousing. Land Rover also played about with the depth of the bellhousing and consequently the length of the first motion shaft. Sherpas circa 1986 used a LR deisel engine with LT77. R380 2 wheel drive boxes do exist but are usually fitted in TVR,s There is choice of gear lever mounts SD1 and TR7 one,s move the lever just behind the propshaft flange, Sherpa,s keep it forward over the tailhousing. So in short you need a RWD box, a shallow LR bellhousing and a Sherpa gearlever mount.

The LT77 is available in RWD with bellhousing already attached for the 200TDi. You need to track down a gearbox from a 2.5na Land Rover powered 400 Series Freight Rover / LDV. The engine was a common upgrade for Series Land Rover's and at one time plenty about. The 2.25 Land Rover belhousing is the same as 2.5na, 2.5 turbo and 200TDi hence the 400 Series gearbox will fit.

Found it   Looks like a nice fit. I am a bit naive as to how the linkage works on this gearbox (I have rebuilt a couple of series LR boxes but that is the extent of my knowledge). Is selection done purely with the 1 rod at the back and by rotating it either way and backwards and forwards? If so making an extended gear linkage may be a bit of a low cost but interesting challenge. |

If so making an extended gear linkage may be a bit of a low cost but interesting challenge. Yes, you got it, the sherpa remote has a ball socket that slides onto the selector rod and drops down so the bottom of the gearstick acts directly on the selector rod, the saloon types extend rearwards over the output flange. The Land Rover type has a different rear cover, and a different selector end, which takes the movement upwards then from that a seperate selector mechanism is bolted which either takes the gear remote forwards or backwards a bit. I reckon it would be possible to fabricate a forward mounted remote selector using bits off both types of gearbox, just depends on how far your knowledge and capabilities go. |
