Puma 2011 2.4 TDCI Xfer Case Temp

[George_S]

Hi, I have a Madman EMS2 installed on the Puma. Recently I was travelingon hilly tar road at 120-125kph on a hot afternoon and the alarm for the Xfer case Oil Temp (set at 111'C) went off.
Stopped, felt the Gearbox and xfer case - too hot to touch. Traveled on at about 110 kph and temp ran at approx 108'C. As soon as I got to 120 - alarm sounded again.
Does anybody know what temp these xfer cases run at.

I would suspect they run at up to 111 degrees at 120-125 kmh in a hot day in hilly country
Puma boxes run hotter than other models and fail more readily from what I have heard
You could run an extended sump to assist Ashcroft Transmissions
I think the real question is what can your oil type cope with I note that the Roamerdrive oil temp limit is 110 degrees ?
I have a TD5 Defender and have seen 100 degrees under similar circumstances
