Title: My first Mog (the rust files)
Post by: Capstankid on April 03, 2016, 11:03:36 pm
How do?
After looking about for a few years now I ended up finally buying a u900 with the cascade box, front and rear hydraulics and a rear PTO.
There is a lot of rust on the cab ( I am surprised I haven't fell through it yet). Sometimes I wonder if it's to much. Mechanically it seems pretty sound apart from an air leak and the brakes sticking on. First plans are to try and tackle the rust on the cab and put supports in to get the cab off so I can sort it out in a whole. Whilst the cab is off I am going to rub down the chassis and wax oil everything I can and just give it a good overhaul of service parts and cleaning it up.
its going to be used for Arb work so the plan is to get a 10inch ground fed chipper on the back and build a tipping chip box that goes up to the cab, this may change as I am thinking of putting a hiab behind the cab and the chipper on the front for nasty Hawthorne.
Going to try and make this thread picture heavy as I have took a few photos but I can't seem to upload them of my phone at the moment.
There's a few questions I have been meaning to ask;
Where's the best place to get service stuff like oil and brake stuff,
Does anyone have two spare doors because I think they are beoned repair.
The diff lockers wouldn't work, would this be due to the air leak, I was making 4 on the little dial, what is it meant to be?
What's the words of advice with projects like these what mistakes has anyone made? I think my first mistake maybe thinking about leaving the straight through pipe on.
I am useless with computers so there maybe a delay in replays.

Cheers
Joe

I'll just post a quick reply as I'm working, I'll get back to you on the other stuff later.

Do you have any pics of the inside of the doors? They look pretty repeirable compared to many I've seen! :P

Nice little mog you have, don't worry about rust, it can all be cut out and welded.
The doors look ok to me, you can get repair panels for the door bottoms and door pocket. Sounds like your building a mog like I had in mind! I've a tp 760 chipper for sale soon if you want to get up and running quickly? Brian knows the one I have ☺
Title: Re: My first Mog (the rust files)
Post by: casto on April 04, 2016, 07:38:45 pm
Forgot to add, which type of air actuator have you got in your mog? If it's an early mog, it's a big handle you pull in the cab, or if it's a later mog its a small switch in the cab?
Title: Re: My first Mog (the rust files)
Post by: Capstankid on April 04, 2016, 08:23:39 pm
Cheers casto, it seems like me have the same plans.
Yeah I am not to worried about it because I use to be a fabricator and the mog was cheap but still I need to get it working to make its keep. What's the Tp chipper like from a using point, I love jensons but the just a bit pricey, I have got my eye on a Farmi 260 that I use to use it just needs work done to it too.
Where do you get the door panel bits from this maybe easier than me trying to patch everything.
It's a 1977 disk brakes mog I think and I haven't found the air actuator yet, it was hard enough for me to figure the gears out ha.
Another thing is it needs the cab rubber mounts are perished and I wouldn't mind replacing them, I seen someone was on about Lamborghini rubber mounts do they do the job or are the originals easy to source?
Also it needs rear linkage is there any other tractors this can be switched from?

Wish I had the mog for that photo of the oak 😢 

Cheers
Joe

The tp produces realy nice chip, nice enough to put in wood chip boilers (which is why I bought it but the job didn't come of) and for a 8-10 inch chipper runs realy well with low hp. Other advantage with this one is the pto comes out pritty much in the right place without a banana box.
Have a look o  the german ebay, there's a lot of parts on there, or there are a few dealers over here that will have it in.
I'll try get some pics of the air switch that does your 4x4/diff lock

77 u900 should be a lever right next to your leg pull it up two clicks you should hear air valve clicking.ten inch chipper is big for a u900 it will drive it but don't push it to hard as the pto box and clutch spline will suffer.
Ready your post your sticking brakes need sorting don't drive it with the brakes dragging as you'll cook the hub oil and that will destroy the hub gears very expensive to fix.

Post by: Capstankid on April 05, 2016, 12:46:31 pm
Cheers Castro, you will have to send me some photos of it.

I wondered if a ten inch chipper would be to much, to be honest I wouldn't be putting massive stuff through it all the time because most of the timber will go for logs but it's Laylandi that I would just blast through it.
I never knew that moose, luckily I haven't went far in it as it's just coming in and out of the garage.
Title: Re: My first Mog (the rust files)
Post by: casto on April 05, 2016, 06:51:05 pm
Lol sounds like you chip stuff like I do anyway! The chamber of the chipper is at 45 so will cut timber better. As moose says, 10 inch is a big chipper on a u900.
Title: Re: My first Mog (the rust files)
Post by: Capstankid on April 05, 2016, 09:26:11 pm
It's the only way to make money  ;)!
45 degrees is better for the chipping and it's less stressful on the mog. I am not sure about the side feeding especially because it's the wrong side.

Anyways had a spare couple of hours so I did a bit more grinding and I have made a few more supports up but I need to get some 90x40 box for the sills. Then put the plate in and take the cab off and give it a good scrub up ready for painting.

Had a look for the lever next to my leg and couldn't find it, I guessed it was next to the handbrake but mine is knackered.

Title: Re: My first Mog (the rust files)
Post by: Capstankid on April 06, 2016, 10:25:39 pm
Yeah it still doesn't work, hopefully it's just because of the air leak. Rear left and front right were spinning.

Got another couple of hours done. There's less and less to each time but still a heap to do. Got the structure about sorted so just need to get the cab off now and patch the holes.

Still not sure about the doors tho Castro, there in fairly bad shape.

Casto got someone else to weld his cab up, so he cant say that they're not that bad! :D
I'd just get new door basically, there's a lot of work to weld them up.
Title: Re: My first Mog (the rust files)
Post by: Oliver on April 07, 2016, 02:23:31 pm
Regarding the Diff lock lever and solenoid.
The solenoid valve your looking for is mounted on the top of the gearbox at the very back, look straight down inline with the back of the cab. You can see it in your photo of the back of the cab! :D
There's 2 air pipes on the valve, 1 of them splits into 2 disappearing off down the torque tubes.
The other heads back to a valve of sorts, I believe it only lets air through at a set pressure. Possibly more than your 4 bar.. 

I'd be checking the lever is all the way up, has it made the 3rd indent looking underneath the cab?
From my own experience the rubber boot on the solenoid goes extremely hard, stopping the plunger operating.
Take a measurement across the plunger before and after you've engaged the hand lever, has it moved?

He didn't rebuild the doors thought! It's has approved merc ventilation 😂

I was meaning it would be easy enough to weld in the re pair panel that you can buy!

Will pm you moose!

Cheers Oliver., it was definitely at the top but I didn't heck if it was on the 3rd notch. When I get a moment I will check it over. Glad there's forums for help of you lot.

How do you know the difference in the cabs moose?

Casto, do you get them of German eBay. I really wish I had paid attention in German at school now!
Title: Re: My first Mog (the rust files)
Post by: Villager on April 09, 2016, 09:41:52 pm
The difference in cabs is the 120 and the 121.

the 120 is the canvas top, although they're predominantly flat screens the doors are flat (no curve at the top), and they aren't as tall.
They also built some with a round screen (like your cab, which is a 121, but the 120 had a soft top), the round screen cab shared the same doors as yours.
 
The 121 is the hard top cab like you have, they did crew cab versions off this cab, including the 145 which was a 406 (short wheel base) and was only sold to the military).

so in conclusion, you can tell a 120 if it's a soft top :)
Title: Re: My first Mog (the rust files)
Post by: Capstankid on April 10, 2016, 09:07:02 am
Cheers villager. I will have to do some looking about for doors as it's coming on nicely, I did a late nighter (2am) on it last night and got a bit done.

Anyone noticed the rear linkage on ebay?

Post by: Capstankid on June 22, 2016, 11:46:11 pm
Finally got round to getting the parts for the unimog, I now have the Rams and everything apart from the lifting arms for the rear of the mog. Hopefully at the weekend I will have a din plate for the front and a front din linkage to go on but I think this could be off a later version.
Struggling at the moment to remove the rear bar where the pto attaches to. I am trying to remove it so I can wire brush everything back then I am going to Raptor spray the full chassis. I also found a leaky air pipe on the front that's put my air pressure up to 7.5 bar!
Will upload photos shortly.

Thats great, i was just wondering the other day how you were getting on with things.
Title: Re: My first Mog (the rust files)
Post by: Capstankid on June 28, 2016, 01:57:58 pm
Finally got half a day spent on the mog today. Had to grind out 2 bolts that held the x frame on because they rounded. you can notice in one of the photos that there is a pin welded which holds the back on, is this normal? It was a nightmare to get at to grind out and knock the pin out but it came of easy enough after I did it. It's been a bit of a nightmare but I am glad to slowly be making progress. Next job is to rub the chassis down then I can get on painting it!
Title: Re: My first Mog (the rust files)
Post by: moose on June 28, 2016, 06:40:45 pm
If it's the pin I think it is yes it's standard you need to take the rear crossmember bolts out first then take the side ones out to release the cast brackets always best to spray these bolts well in advance.
Moose
Title: Re: My first Mog (the rust files)
Post by: Capstankid on June 28, 2016, 09:34:30 pm
I did that the other day, thinking that's how it came off but problem was the the bloke who had it before decided to weld the brackets on so I was a bit stuck between a lot of grinding or a little bit.
Just been told I have 3 days to move as well as the bloke who owns the shed I have the mog in is moving!
Title: Re: My first Mog (the rust files)
Post by: Capstankid on July 02, 2016, 08:41:10 pm
Had a full day at it today but the rain was that bad it was coming in the shed and I only got one photo before my phone died.
The x frame on top has been fully rubbed down and ready to paint, some of the back is brushed up. I have just got a couple of pipes to change and do a bit more with the wire brush then the back will be getting painted and then just fit everything back together.
I also changed the engine oil, gearbox and rear axel.

A few more photos of stuff done. I haven't had a lot of time at the minuet but slowly getting there, rear linkage is about finished. Sorted the diff locks out and was well impressed where it could go even on bald tyres. Has anyone found that knocking the diffs in and out uses a lot of air?
Title: Re: My first Mog (the rust files)

Using the diff locks shouldn't use a lot of air only a hundred cc's or so are they leaking normally given away by the smell of EP oil coming from the top of gearbox.

Title: Re: My first Mog (the rust files)
Post by: Capstankid on September 06, 2016, 06:48:13 am
I don't think they were leaking, I had a look around to see if I could hear any leaks but I couldn't find any. If it's left for a few days the tank still holds air in it. You can smell like gearbox oil but I kind of thought that was just normal.

Anyways, I did a 738 mile round trip at 16.6 mpg on the way back and bought a chipper and tipping box which was off an old transit then converted for a u900. I am well pleased with these buys. I am giving myself a bit of a push and going to try getting them on and working for the weekend. Started getting the hydraulics all connected up. Do you have to have the link arms all the way up when you go to use the tipping ram, I am really struggling to figure out how it all goes.

If anyone has a spare set of link arms I would be interested in purchasing them.

Has anyone get any tips for insuring the mog, I went to go through Nfu but they told me that they don't insure unimogs and Trust insurance is quoting me 800!

Title: Re: My first Mog (the rust files)
Post by: Capstankid on September 07, 2016, 10:07:24 pm
Finally got the back on tonight. It's took a bit of figuring out on the tipping ram but it works. The back seems to hang over a foot and I am worried that the chipper will catch on the back. If anyone has a chipper on, could you measure from the back of the mog to the front flywheel plate on the chipper please. I haven't bought the link arms yet so I could make my own up that would be longer.
Sorry for crap photos, bloody late nights.
Title: Re: My first Mog (the rust files)
Post by: casto on September 08, 2016, 06:35:14 pm
The top link will probably foul the body, as both of mine do before it reaches the top of it arc. I wouldn't bother making longer arms as your just moving weight further away from the axel. Either don't lift it as high (as I did) or cut a channel into the floor for the top link to rise through. Are you making a 3 way tip for the chip box or are you going to have to take the chipper on and off to tip?
Title: Re: My first Mog (the rust files)
Post by: Capstankid on September 08, 2016, 09:19:56 pm
Just found that out tonight Casto, the body will only lift 200mm. I am not sure if it's going to work and I need it for the weekend. Cutting the floor sounds the easiest option if I am honest, I will crack on with it tomorrow night. Happy to see it with everything on tho. I have a din plate and front links to go on, I am thinking of just using the front to transport it and put it on the rear to chip. I have a double drum winch that I wanted to go on the front.
Title: Re: My first Mog (the rust files)
Post by: casto on September 09, 2016, 06:25:53 pm
I'd just stick it on the back. U have a tp chipper don't you? They don't sit to low and you'll be suprised how much chip you will get in before you have problems with the chipper hitting the road (usually speed humps to be fair) You'll probably find that it's a pain running to a job with it on the front, then switching it round to the have it working on the rear. Mine hardly used to be taken off the mog as there was only me to hitch it back up again!
Title: Re: My first Mog (the rust files)
Post by: Capstankid on September 09, 2016, 10:51:36 pm
Just a couple I got with the chipper and body on.
Title: Re: My first Mog (the rust files)
Post by: casto on September 10, 2016, 08:48:33 am
Looks good! Err yeah that body is rather long 😂. If it was me I'd loose the tool box off the front , move the chip box to behind the cab. Gives more clearance for the top link and moves the weight of the chip forward. I found with kassy, she would be rather light with the steering when she was full of chip.
Title: Re: My first Mog (the rust files)
Post by: Capstankid on September 18, 2016, 01:43:55 pm
She did the job of running chip back and forth no problem. We figured out it was 21 cubic meters of chip we took away in the end it was a long day!

Yeah still haven't figured out how to mount the chipper on, even thinking of making a top link bracket actually on the chipper body. Will sort it out and get back to it.
Title: Re: My first Mog (the rust files)
Post by: casto on September 19, 2016, 05:31:01 pm
She shouldn't even break a sweat doing that 😊 glad to her she ran ok, did you have a road tow chipping? I've always had a truck to do the humping of chip then put everything else in the mog
Title: Re: My first Mog (the rust files)
Post by: Capstankid on September 20, 2016, 12:35:35 pm
Yeah, I get the road tow really cheap and it sucks Laylandii through like nothing.
That's what I want to do but the young lad I have working for me can't drive yet and I don't trust him driving the mog.

Going to try and get the NATO hitch off tonight, any tips on how it comes off?

Really need to update this more often.

I am still struggling to upload photos tho.

Finally got the Mog sorted to somewhere I was using it, I made a fixed pickup hitch and attached my Botex trailer to it.

Long story short I was coming home in the Mog and went round a right hand corner a bit fast and had a blow out, it through the Mog on it's side and me out of the window. luckily I was ok  but the cab is totalled and I am on the look out for any condition cab just to get it back working.

Crikey you were lucky to be ok after a trip thru the winda. how did you get it cleared up, was it a road blocking police job or or a local recovery wagon on a quiet lane.

Yeah I was really lucky. Fortunately they were silaging next door so we just pulled it over with a chain.

I am back to square one now. I'm going to take everything apart and restore the full Mog. It's been a really good assist to my business and I am going to Gretna tractor soon to do the towing work and make the Mog into a winch tractor!

Cheers for the reply mate!
Yeah I was thinking about getting the 416 and breaking it as it would make more sense. I am.also thinking about just sorting the bottem and welding a cage for the top and a perspex window and replacing the roof when I find one.
I couldn't believe the price of Vos for a reconditioned cab!
