Thread: puma transfer oil change interval

Blknight.aus
What type and brands of oil do you use in the transfer and gearbox.

FWIW I'll put a plug in here from personal experience for Mobil Agrifluid 424 SAE 80 tractor transmission oil for use in transfer cases. I put it in the TF case of my P38 several years ago and change it out every three years regardless, as there is both a time and heat cycle deterioration on lubrication fluids. It's great for extreme heat, shearing stresses caused by heavy bearing loads and resists moisture deterioration etc. Further, the TF case became substantially quieter in its operation... It's not readily available in the "city". Prob. need to get it from a farm supplier/produce store etc. or a Mobil depot
cheers

I would hesitate to use that as it is twice as thick at 100C (approx) than the ATF that Land Rover and Borg warner recommend. &0-80 about 14.7 centistrokes at 100 C vs ATF at about 8.
I did some research a while ago and all chain drive BW transfers had ATF recommended and Borg Warner only recommended ATF on their site. I was hoping for some thicker recommendation but it wasn't to be.
The reason it seems is that they have an oil pump which can break with heavy oil on a cold morning.

Hi All. I did the modification to the transfer case by using the enlarged, finned sump and it took approximately 0.9 L extra oil to fill. This is on a TD5 130. I bought mine from Ben at Modern Motors as well. Cheers, 130man.

dex III for the box 80/90 for the Tcase unless I was expecting the next 50K Km to be predominately high speed work in which case it would get dex III as well

I dropped my transfercase at about 8-10k KM after i got mine, The oil that came out already looked a bit off and the new stuff that i used quietened down the drive train noise quite a bit, i was surprised at the difference considering the stock oil was so new. Reason for the change was i accidently dropped some oil out playing with the output flange so i decided i didnt want to mix new/old oils so dropped the lot.

as mentioned, this affliction seems to be confined to the puma models only.

On my now sold Puma, every six months. I only did long distance trips in it with a load and boat behind. Not worth the risk at the cost of a couple of litres of oil.
