1120 AF Build in Norway

[Madoxen]

It might be specific to your model as on my 1835 there was nothing to come off other than the dual tyres and then the super single went on, there were no spacers or shims or rings (which is what i think he is suggesting) but maybe there is something more on the 1120 AF

It was a couple of years ago for ours but I do not remember a ring being removed. Maybe it depends on the rims being installed?

The same rims you have i think (110 offset)

Today was a learning experience,we couldn't release the parking brake (because we didn't know how it worked correctly).

Plus side we tilted the cab and followed all the neumatic lines and values to their respective ends back to the tank. The truck has been sitting for 2 weeks now but we still had about 6 bar in the system although we did find a small leak at one of the tanks..

All in all a successful learning experience!

The next time you have your can tilted could you take a couple of pictures of the hydraulic ram that tilts the cab? Especially the attachment point to the cab. Really wish ours had come with one.

Sure, no worries! How do you tilt the cab currently?

Hi, this is my one on a double cab fire engine. Hope it helps

We have the not so reliable "Armstrong" system ?. Seems the Swedish firemen were plenty strong to heave the cab up. From what I have gathered MB used a bunch of different lifts, depending on the size of the cab. From the bit in your picture it looks like the one that would have been installed on our truck. We have the bottom mount on the chassis but I think I am missing the attachment point on the underside of the cab.

It should be illegal and it’s definitely immoral to produce a cab-over truck without a hydraulic cab lift. How the hell does one access the engine in the middle of nowhere by oneself or with one co-pilot?
It can easily be lethal.

The "Armstrong" system has a bit of assist with a spring, sort of like a garage door, then a locking strut once in position. It was actually pretty easy when we got the truck but adding about 100lbs of sound deadening, air ride seats and a rooftop AC really made it a bit more difficult. If I can figure out (and buy) the cab mount I will add the standard MB ram with possibly a DC reversing hydraulic pump (easier to package as our batteries now sit where the manual pump looked to be located).

Perhaps you have already tried this, but on the Fusos which are 'unassisted' cab tilting, if you open the doors it shifts the CG forward and makes lifting the cab easier.

I would be very reluctant to tilt my cab (1017) with the doors open. They weigh a ton and would probably rip the hinges off Neil

UPDATE AND DISCLAIMER - I would not attempt this, even as a trial to see if it helps, if you feel the build quality of your Mercedes is substandard to a Mitsubishi, or you do not want to add a tether to your door. As always YMMV

I actually opened the doors while tilted. They are not that heavy IMO (comparing to modern land rover doors) and certainly didn't rip off ?

I think the doors on the older NG cab were a lot heavier. I remember when we painted it we had to offer up the doors to refit with a forklift. There were physically too heavy for two of us to lifrt ip and getbtge bolts in place .

I've opened the doors (front) on my 1979 1017AF dreifachkabine when the cab has been tilted (not to 'assist' in raising as I had a ram) for maintenance and they did not 'rip off'. Of course, I opened them 'under control' supporting them down to the stops. IF I was doing that routinely I would either add a support cable to the back latch or even better a support rod in case of wind gusts. I will agree that they are too heavy to use 'human power' to install when not attached to the truck, due to their weight and height above the ground (extrapolated opinion, no direct removal/install experience).

 

[Joe917]

I agree with Neil, the doors are too heavy to leave open while tilting the cab. The hinges will be under huge stress as the cab stops moving when tilted. I would not even leave the door open without support when the cab is tilted.
