HI all here is a picture of my new UNIMOG it will be transported home in 2 or 3 weeks

Cheers Rob

Looks good Rob. Travel safely.

 

[Dreadnought]

Hey it looks like a twin brother to mine (albeit one that,s just been in a fight outside a pub!!!!!) I,m sure you will have it fighting fit soon enough and if you decide to bring it down this way I will show you round the tracks of Salisbury Plain. Have you noticed how being LHD doesn,t matter in a Square Cab Unimog because with no tilt on you can see all round in traffic conditions, I feel safer in the mog than in my Pinzgauer.

Where is home Rob?

 

[6 pot]

normalbloke home is Leicester.
Cheers Rob

 

[rostige]

Best of luck with it Rob; Leicester?...the home of Red Leicester cheese? (I only know it from the Python sketch) every time I think of it I laugh.
Small note Rob...make sure they get some kind of rain cap on that air intake (it looks missing) before they send it preferably...don't like to see water get in there.

Cheers, rostige

 

[needmog]

I'm with Rostige

Here is one you can buy:
Unimog DB LKW Zyklonfilter Regenkappe Schnorchel NOS bei eBay.de: Transport Logistik (endet 07.02.10 20:49:06 MEZ)

It'll make your mog look like new

Just on the subject of that snork cap, one of the little jobs you should think about, (especially if that cap has been off for any length of time) is getting the filter out and having a look and then cleaning up the tin drum it lives in! Mine had some nasty rust. It is well made so even big flakes dropping off like on mine were not too bad, check all the seams, water seems to run down and pool around the seams, I cleaned all the rusty bits first with a screwdriver to get the chunks off and then with a wire brush, after which I greased it all. Its no good thinking all is Ok then going into deep water which gets in through a rust hole hidden under the filter drum causing ££££ damage. Just on the subject of the odd water splash, I note that there is a rubber (leaf/debris collector in the bottom of the filter drum and I,ve seen vids of SBU,s in deep water with the fans/pulleys throwing water all round the engine bay and out through the filter side of the grille!!!!!! doesn,t water get sucked through the rubber thing into the engine???? or when going through deep stuff is there a blanking cap????? I check my filter often enough that I can live without the rubber thing and I am going to blank it off. Is there a special reason why I shouldn,t blank it off?

 

[normalbloke]

Mine only has the rubber teat on the heater housing, not the air filter side.I don't know if mine has been modified by a previous owner or it came like that.Don't forget to remove your primary fan belt before wading.Thats why it is the outer belt and has the tensioner so that you can do it by hand in <60 seconds.

 

[Dreadnought]

Ah another snippet of very useful information, I will be blanking that teat off. I can,t see the sense in it, having seen the wading that the German Forces do at their driver training bases, but who knows? perhaps some Mercedes engineer will say NO! the design of the teat is such that it will not allow a dangerous amount of water to be ingested!!!! I hope not to have to go in that deep, but in the area of Poland that I will be living, a lot of the forest tracks seem to cross (blue wiggly lines on the map) which may be rivers, brooks, or just little streams, but having said that I,ve been out in a Landrover in mountains and crossed a trickle of a stream in the morning only to find on return in the evening that the same stream is a raging torrent barely passable by a Landrover!!!!!!

 

[coachgeo]

if it is on there... it's on there for a reason. I would in no way go blocking it off unless I understood rather FULLY everything about it.

With all the Mogs out there fording water.. odds are good there is something in its design to keep it from ingesting water. My guess is there is positive pressure on it that pushes outward so water wont go inward. Like a check valve. It's one way only?

But.. your right to not assume. Keep searching and asking you'll find your answers. Odds are the answer will be its designed not to ingest water.

Ff it is on the bottom of the airbox,it will almost always be under negative pressure.If it fails and there is water about, it will suck it right in.

 

[Dreadnought]

Yes the 'teat' is on the bottom of the airbox, it is a round rubber moulding that is formed into a slit at the bottom. I have noted that some have this teat/debris collector and some don,t! some also have that summer/winter flap, mine certainly doesn,t. I think I will remove the teat and plug the hole, but will check the airbox every few months to make sure debris/condensation water is not building up. Having the teat or the flap seems to make a mockery of having that big snorkel? I have always been told that all joints must be completely water tight from top of the snorkel to the inlet manifold.

 

[dxmedia]

Exactly the same as my old trooper had. They are designed for draining water out of the airbox which is sucked in via the air feed in. If you've a snorkel with a cyclone top on it then blocking that rubber teat will have no ill effect. If your pulling air in which may be effected by rain then you'd need to keep an eye on the airbox to stop it getting any amount of water in.

According to the manual, the rubber valve on the bottom of the air cleaner is for dumping out any loose dust that has settled in the air cleaner housing. By squeezing the bottom part of the rubber, it opens up the slit, allowing the dust to drop out. Care must be taken that when closing the slit, no dirt is left on the lip. This will ensure a proper seal and prevent anything getting sucked into the housing from below, be it water or dirt during normal operation or fording activities. That is the theory at least. It is part of the regular maintenance to check that valve.
You just have to squeeze the teat once in a while.

Congrats Rob, Would you have more photos you would care to share?

Best of luck to you and your 'new' mog!

Now thats showing how technical a simple rubber 'teat' can be. I thought it would be something like that and that it is no more than a 'slit' when working, but I,m still a believer that nothing should be left to chance when negotiating deep water. The valve may work, it may not? If it doesn,t work on a Bundesheer Unimog and she sucks in water, then a big recovery truck will just drag her home and they will rebuild the engine or put in a new unit courtesy of the German Taxpayer. Me..I,ll be up the proverbial creek without any sign of a paddle, so I,m going to blank mine off and check the filter box much more often, I,m a stickler for servicing so I,m not going to forget it.
