From memory, 3/8" BSP.

I'm not sure the oil will have any reason to move backwards & forwards through the pipe and heat transfer would be slow through the pipe section.

Mike, what's the drain plug thread ? I'll see what banjo fittings we have at work.

I will check the tread tomorrow and let you know. I doubt if the oil will move back and forth. I was just trying to increase the capacity . I could put a cooler in line and run a pump through the catch can and back into the casing through a tapped hole at oil level height . Finding a tiny little pump that didn't overfill the OD would be a problem. :)

glad to hear it was an easy fix!

you can get the alloy transfer case cover they use with the roamer drive as well and it drops the heat a bit.. stops a couple of weeps as well!

my toro pumps it's oil into the transfer case! bloody thing it is....

might try pulling the seals like dandylandyman

i thought i read they are supposedly making the fairy overdrives again from november this year, so all the parts will become available again...

so I take it that they all leak and you just have to put up with it, and the can is like a slow top up system , the sight glass is a good idea.

Eventually they all leak into the transfer case mine hasn't lost a drop try now with 200 is and it's going well. I found a oil cooler laying around while cleaning up today and I'm thinking of adding it in between the OD and the catch can it will increase the volume even more and help cool it . I have noticed the OD does get quite warm. Trouble is finding a place to mount it so it gets flow through air but won't get a stick or rock through it. :)
