Thread: Puma 130 Transfer case issue(s)

I had a transfer case failure:

Transfer box failure

I had an intermittent growling noise from the gearbox /transfer area, when I drained the transfer oil half the input gear teeth came out with the oil. Might be worth draining your transfer oil and see if there are any lumps in it, might give you an indication of whether that is where the problem lies. I sourced all new internals from ashcrofts and rebuilt the transfer case.

Hi,

Just got my MY2010 110 Puma back after transfer case rebuild/replace at 146,000 km. The main gearbox and clutch had been done at 85,000 km. And I reckon I and fairly gentle on my truck.
A couple of monthe ago it was in for a service and the indy found 5 broken teeth on the magnet sump plug. There was no excessive or unusual noises and the truck seemed normal. But I did not try it in low range !
2 weeks ago I took it to Bruce Davis to get it fixed. Seems a previous indy had not put the shaft back in properly after replacing the rear seal with the result that the gears were not meshing properly. So an upgraded case , replacement for the damaged gear ( 2nd hand), upgraded coupling shaft and 2nd hand inter gear and it was back on the road in less than 4 days.
But after about 20 km got this very disturbing woo, wooo, wooo noise particularly on over run.
So back to Davis' and they replaced the replacement gear and the original gear with 2 x 2nd hand parts and now it drives like a charm.
An interesting exercise.

You can use a late model Discovery 2 (say a D2a) transfer case....

*Same ratio, gears etc.
*Same front nose cone, but the D2a has 2 diff lock switches (Defender TDCi has one)
*Same front lower detent on the front nose cone.
*Same diff lock switch (the later larger thread).
*Same additional casting ribs on the top of the case.

*D2 rear nose cone does not have the provision for the speed sensor.
*D2 Front input flange is bigger.
*D2 the diff lock top mount has three bolts, 2 of them are longer as they hold the diff lock cable bracket in addition to the top of the diff lock lever, they need to be spaced or replaced with the correct shorter bolts.

OK, so I have a second hand transfer case - it appears to have been rebuilt at some point looking at the sealant on the case and the input splines appear to be in good condition. It is a 36D and has a speed sensor on the output housing so its not a D2a. It looks like it has been sourced from a wrecker as the handbrake cable has been cut with bolt cutters. A question for the brains trust:

Will this case bolt into a Puma as is ? My current tentative plan is to bolt this box into the Defender to give me time to get mine rebuilt properly with the insert done to stop that bloody leak and most likely an Ashcroft centre diff fitted.

Does this make sense?

the 36D is from a late D1, yes you can use it but you will have to swap the high / low lever and you wont have the switch for the hi/lo but this is not too important,

Pulled the cover off the second hand box today and everything looks pretty good inside. It's obviously been rebuilt, is there any way to tell without disassembly if it has an ATB in it?
Made up a bracket for the trolley jack and need to get some 30mm rod this week to finish it off.

If it has an ATB fitted, you shouldn't be able to turn the front and rear output shafts in opposite directions by hand as it is a pre-loaded worm gear design.
