Thread: Isuzu MSA Gearbox to LT230

Thanks. That was an interesting read. Nothing is new eh.

Actually looking back through my notes he said pick which diameter.
409.3
404.94 mine
416.0 or
397.5

Isuzu 4BD1 Bell-housings..

Yes, I found that out too That put an end to my Allison AT540 project ideas...

I just happen to have a truck with a 4BD1T and an Allison AT 545 sitting in my shed, it was converted by Detroit diesel back in 1987 and is still going strong.

They used an adapter for the bellhousing and bolted the flexplate to the manual flywheel. No pics for a while though as I'm stuck at work.

Are you still making your MSA Gearbox to LT230 adapters? If so do you have any?

Still making = Yes. Do I have any right now = no.

Does it require a spacer on the crank to be made for the spigot ?
Once again sorry about the questions but I'm trying to get things underway on driveline as the motor is almost sorted...

The Ring adds 25mm thickness, bringing the landrover housing (80mm) out to the same thickness as the Truck housing (105mm) so no spacer required on the crank.

Ok here’s the deal, two options in regards to the housings;

1. Continue with weldments

Price will go up to take into account some process related costs I didn’t factor in.

2. Move to Aluminuim casting

I can maintain the current price, however would need at least 20 people to commit before I outlay to get this going – although these people who committed would get a discount.

And to show my appreciation to those that have joined in on funding the development of this conversion – those that have purchased a steel weldment version would be able to swap out to the Aluminium Housing for free if they so desired (in exchange for the return of their current housing).


In regards to the Shift Kit, once again, two options;

1. Stick with the current linkage kit – prices to go up as per same reasons as above.

2. Move to the replacement top cover plate that utilises the LT85 selector (Defender/County only so far)

I would need at least 20 people to commit to this before I develop this any further. For anyone that commits I will keep the price no more than what the current shift kit cost and if it actually works out cheaper I will pass that saving on.

Once developed, I would then offer the same swap out to those that already have a kit – although most likely at a fee.

As it isn’t developed far enough yet, I cannot confirm any prices.


Of course you could always rig up your own shift kit and I just supply housing/shaft.
