LT230 transfer case upside down

Recommended Posts

crazy idea ?  ( probably ) 

fitting a LT230 to a P38 would require mounting the case upside down.

for my application, I am doing an engine swap at the same time, so making brackets and divorcing the new engine from the transfer case anyway ( even if I stick with the borg warner )

other then the obvious case venting issue, anyone see any issues with proper lubrication, seals etc ?

 

anything im missing ?  ( probably )

I'd turn it around and drive it through the PTO. Was just discussing this in another thread.

There's no room. And you'd have to change the rear too. It's not a Jeep, both axles are offset.

Yep, the hole in the middle of the input gear runs right through so the splines are accessible from either side. You'll just need a slightly longer input shaft, but as you're doing a divorced setup that won't be a problem.

There's already remote LT230 kits from various places - I'm sure I saw one recently from somewhere like Rakeway or Milners, same place was doing stubby front output housings.

does anyone see any issues with lubrication ?  I saw somewhere ( cant find link now ) where some custom application with dual boxes and one was vertical mounted ?

I've never used them but several people have told me Rakeway can be very variable for custom work in terms of timescales (both promised and actually delivered)

I think that one is parked up at the Range Rover Specialist near Witney, Kingsley Cars. There was certainly a red one there when I popped my head in a couple of years back.

The intermediate propshaft bearing in Mouse was from Rakeway. 😉 Not cheap, but good service when it needed replacing.

This pic shows the transfer box arrangement of the esargo:

Definitely the second transfer box driven from the PTO side.

Good to know it's been done. Now if only we could swap the front and rear output housings, so handbrake stays at the rear...

I like that, simple and clever, at the same time.

The technical drawing says that it's faily different:

Handbrake is a secondary problem to solve though isn't it? There's plenty of ways to skin that cat.

Well, preferably it'd look stock... for MOT reasons in Belgium.

no, but that is pretty cool !  this one was vertical ( mounted on its end )  so input was on top, and outputs on the bottom.

 

my main concern is lubrication, but seems like if the gearing is properly wetted the oil will get slung around pretty good.  

also would need to make sure venting was taken care of.

so im going to attempt mounting and running the box upside down, and install a new vent line, and plug up the old one.

Well, not really "upside down" as the input side is higher then the output side vertically, but I will flop it over, so the "pan" is facing upwards and the selector shafts are facing down.

I have found and secured a CDL locking dicso 2 LT230 and its on its way.

 

my only real concern is lubrication, and seals.

lubrication:

should I adjust the fill level to ensure "wetted" gears stay wetted when at rest on level ground ?

or just put in the same amount of gear oil the manual specifies ?

also concerned with inter sling and whatnot getting oil into all the places it needs to lubricate.

 

 

seals:

mostly concerned with the selector shaft seals, they were not designed to be submerged in oil all the time.

anything else on the "top"  ( which is normally not submerged in oil ) which in this installation would be on the "bottom" that I should be worried about ?

 

any and all feedback is welcome !
