Sounds great Dougal, I'm guessing the MSA is invincible? I am interested. is it a RR lt77 position or 90/110?

Yes the MSA's are bulletproof. This one was fitted to my rangie from ~1992 to 2007 when I changed to another MSA with different ratios.

This is the early RR LT77 long stick position where the gear lever is in front of the LT230 transfer lever. I think it's the same as 90/110 but I've never had them out to check.
The short stick position in later RR and discos had the gear lever behind the transfer lever. It's not one of those.

There is a catch, I'm still using bits of it. I need to finish some other stuff before it'll all be available.

Dougal, is it possible to bolt a 4HF1T to where a 4BD was? 4.3L DI

They use a different bell-housing. It's possible to put the MSA-4B series bellhousings on MXA boxes so it should be possible to put the MXA-4H series bellhousings on MSA boxes.

The biggest problem with the 4H series is the rearward facing starter.

I was trying to get some more information on the PERKINS 850 Series.

3.3L turbo diesel, industrial purpose, but low rev. dont know if it is suitable.

Recent Perkins are running 1.1L per cylinder. Is that a 3 cyl?

Industrial diesels often use a governor that is unsuitable for use in a road vehicle. They are may be constant power or constant speed governors, depending upon the application.

For road vehicles the governor needs to be a variable speed variable load type.

I'm going back to the first post and want to ask about why the 15B at 86Kw is better than the 4BD1 at 88Kw?

Are you aware that Landrover diesels had variable speed governors rather than variable power for 25 years? Same as many typical industrial diesels.

JCB have some real animal diesels now. I saw a pump yesterday, 4.8L turbo 4 cylinder.
115kw at 1500rpm.:eek:

But the most interesting thing, JCB list flywheel inertia in their engine specs. I've long suspected the 4BD1 has the lightest flywheel in it's class by about half.
