compare it to other trucks and nobody can compete with it.
as for the wading depth ive no idea, id say the top of the tyres would be safe as a guess, but dont quote me on that :) and yeah, the hubs breathe through the axle, which breathe through the diff, then through the torque tube, then on some (depending on the year) the rear axle breathes through the gear box as well.
-
I had wondered why there was a 1.2m limit. Doesn't seem much for a vehicle the size of a square cab mog.
What's the wading depth of a standard U900? And what needs to be done to increase it? First on my list will be a new filler cap and tank breather - mine are pretty messed up! The breather from the torque tube is present, and I understand the hubs breathe through that section too?
-
in theory the manifold is higher than 1.2 meters, so you shouldnt get any water into the engine ;)
-
In answer to what happens with a cab mounted stack in deep water with the mushroom bottom my mate found out whilst helping out with the floods in Somerset. You get a fountain!! The exhaust gases drew the water up the stack and out of the top whilst running :D. He found it very off putting to begin with and those on the back found it very wet :)
-
Neil, the stack pipe i have i will re use it was all the other pipe work thats being renewed, mines is just a length of pipe fixed to the cab with some bends in it to connect to the silencer box, it has no flex fixings or mushroom bottom to it. i place a can over the top of it if the hogs not working to stop the rain getting in, never had a problem with it rusting away or breaking off its mounts with over flexing.
-
That makes more sense. I've only ever studied an upright stack on a U1000 and that was how it was fitted there. I was surprised that it isn't sealed, but it clearly works just as well.
If the vehicle is used in water does this system change? Surely then the water will get in through the open joint and fall into the upright bit that goes into the stack? Probably not when running, but if you stall or shut it down?
-
That's good to know. I've been thinking about putting one on mine to send the mogstink up over my head when I'm working near it.
The upright stack actually has a mushroom bottom to it, then the tail from the box goes into this mushroom WITHOUT TOUCHING THE SIDES, this means the water doesnt go down into the box, instead it goes down the sides of the mushroom and drips off :) if you have an upright exhaust it needs to flex freely, forgot to mention that, if its just a normal tail pipe it literally bolts on.
-
If your current one isn't knackered, do you want to sell it? I don't want anything fancy as long as it works for now. I can't afford to be too fussy! :-[
-
That's all mine is at the moment but I'm getting a nice stainless one made by a mate who makes custom stainless exhausts.
Tried to work the chipper with a side exit exhaust it was horrible, though you have to watch how close you take the mog to the tree with the stack I've been smoked out in the canopy before :D
-
Can you buy one ready made or is it a case of making your own? Pretty much every one I've seen has been different to the next!
I was thinking just a straight stainless tube with a bend in the end to keep the rain out would do, and attach it with the dreaded flexi pipe! :D
-
i think an upright exhaust is a must with mogs and chippers. even wose with a turntable chipper and your feeding in from the exhaust side!!
-
landies, the marmite of vehicles :D
Yes the flexi pipe is only to join the silencer box to the stack, i will have a new section of bent pipe that sits snug under the body into the stack soon.
-
That's good to know. I've been thinking about putting one on mine to send the mogstink up over my head when I'm working near it.
-
theres no flexy on a 406 :) the box is only held on by 2 bolts, so that flex's with the chassis :P
-
I'm not a fan of landies
All of a sudden I'm going off of you.. But it's ok, Brian will be your new best mate! ;)
Is it a good idea to lose the flexi pipe on the exhaust? I thought it was there so the cab (and attached stack) can move independently of the chassis. Mogs are designed to flex so I'm thinking something attached to the cab and the chassis without the means for some amount of movement will break something? Probably the exhaust?
You've only got to watch one with a large back body driving off road to see how much they do twist. It's pretty incredible.
-
I have a few vehicles as I find it's difficult to get the perfect vehicle for every task, some of my work is a bit of a drive so I take tipper if the chips have to be removed, some the chips to be left off road so I take the hilux. Local or off road site jobs I take the mog. I am thinking of getting a 130 defender tipper this year to do away with my tipper and hilux. But I'm not a fan of landies ohh decisions decisions :D
-
Meant to say thanks for the welcome. Yes I got a surprise with merc too, my local dealer had one in stock!! Not the full system the main silencer box and exit pipe £82.00 inc vat. I won't use the exit pipe so I gave that to my mate who is going to make me a return section to go into the stack to get rid of the flexi. :)
-
hi Robert, welcome to Unimog Club UK, and thanks for saying its informative :) we do try :P
amazing to hear you got an exhaust of merc cheap! normally redonculously expensive! :o
-
How come you run two rigs? Distance/comfort of travel or cost perhaps?
I don't really know why I've got one when it comes to work. I have work I can use it for, but I sure don't need it! My thinking was that I wanted one, so I bought one. If I can make it pay for itself, or even nearly cover it's cost of upkeep, I'll be happy with that.
So far all it has done is cost me money! But then that's what these things do and I knew it probably would before I bought it.
-
you did so :)
I've been running the one i have for 2 year and i had one for about 5 year prior to that with a break of about 5 year in-between. when i ran an assortment of vehicles doing tree work. i do like my mog but it does not get used everyday, i have a tow behind a tipper for most jobs.
-
I so did! :-*
I look forward to seeing your setup.
See! :D
-
welome Robert.
nice to hear another u900 hard at work despite its age. They really do run for ever with a bit of TLC. How long have you been running a mog for? if you have any comments or questions about unimogs by all means chip in,the more ideas the better!!
And as NJC didnt say (hang your head NJC :P) if you have time it would be nice to see your mog setup
cheers Casto

Hi Robert. Welcome to the forum.
I see you've made another post here already so I'm off to read that now. It's nice to hear of U900's being used for what they were originally intended. I've just picked one up myself with the intent of fitting a chip box... It's a big advert to drive around! I'll eventually have a chipper for it too but one step at a time. I look forward to seeing your setup.

Nice forum, some great information here. i personally run a 406 with chip box/chipper for my tree surgery business just fitted a new exhaust direct from merc that was surprisingly affordable. :)
