There is generally just a smell of EP90 anyway as the first time i engaged the difflocks one or more of the breather tubes which run up to the underside of the gear linkages on mine had a fair quantity of oil in it. Consequently when the locks were engaged and disengaged it coughed badly and rust proofed a fair amount of the underside of the cab and chassis. :-)

according to dad, if its a three piece axle, yes it would. but the later ones had a 2 piece axle with an external difflock actuator, so then it wouldnt.
if the difflock is leaking on a three piece axle, there is generally a smell of EP oil when the lockers are engaged.
-
Ah I get you. Yes pipe in place.
As for breathers and air. If the Difflock seal was leaking would this cause the axle and consequently the hubs to get pressurised? In my logic it could.
-
the pipe is the hub breather, the breather goes from the hub, into the axle, into the torque tube, and up to the top of the torque tube and out. (early 406/416's had the breather go into the gearbox it self and then out, i assume they stopped doing this due to the manufacturing costs) if the flexy hose is not connected, which they often are missing, or loose, then muck and water can get into the hub and cause damage, as part of the weekly check over this pipe should be checked.

Villager. There is a pipe between the hub and the axle. I am intrigued as to why that could make a difference?
Just for you NJC

Sorry to hear about the hub. You'll be cursing that poor mog soon (if you're not already?!). I hope it isn't too complicated.
On a lighter note, I bet you gave a few people a good giggle having your recovery truck towed... :-[
-
looks like fun :) shame about the hub :-\ have you made sure the flexy from the hub to the axle is connected?

NJC, there are 3 unimogs that i know of that are currently used for recovery on stage rally's. Mine, the orange one and a yellow one. All 3 are substantially different. The orange one is the original and in my opinion the best. The owner has had it for 12 years of refinement.
Craig, my mog came with a 5 ton hiab behind the cab, the hydaulic winch mounted high up between the lockers at the back and a hydraulic under lift for lorries / buses on the back though i doubt that ever had the power to work properly. I purchased the back off a 7.5 ton Iveco and re-engineered the bed and spec lift that is now on it to fit. New different length rams, pipework, valve blocks, winch mount at the pivot point, multi direction roller fairlead on the spec head, changed the angle of the main dropping beam, lengthened the main dropping beam, mounted the spec chassis on the old hiab mountings behind the cab, fabricated / mounted the back of the spec lift body to the rear cross member, rewired and refitted the rear lockers. On closer inspection those in the know would realise that this is only version 1 of the spec lift mounting as with the hiab mounting plates (15mm thick, over 700mm long along the chassis and in the region of 500mm high) and the fact that i have bolted the spec to the rear chassis cross member this has removed the flex out of the rear chassis. In time i may change this to allow for flex but in the use that i intend to give it this is really not a high priority at the moment. It took mos weekends between the end of August and the start of the WRC to get as far as we did.
As for how the weekend end well it did all i asked of it until i picked up to tow the caravan home. I managed 30 miles from the camp site with 70 more to go and pulled into a garage for fuel. It was dark and until that point i had been moving and had not noticed an issue. However upon stopping smoke was billowing from the front offside hub. On inspection it was boiling the oil out of the hub as i think the bearings have collapsed. I moved it to a gateway and called a commercial recovery operator that i know. The net result was sleeping in the caravan and being collected the following morning. It was cheaper than a sunday night call out. As yet i have not had time to get the wheel off and start stripping the front hub to assess the damage. That will now be my winter project.

That looks like great fun! Cheers for posting the pictures. How many mogs are there in the group?
-
looking good :) nice to see pics of mogs out earning there way. how did she did in the end? any problems?
i see your not the only one with a mog there ;)
-
Thanks for sharing, looks like you had a good weekend.
Did you put the spec lift on, and build it up yourselves?

This is why I bought my Mog
