Cab Air Conditioning

I wanted to have an separate air conditioner for just the cab alone, After a bit of research i decided on a Weaco RT 880 its a stand alone 24volt system that requires nothing but a 24v connection.

It has a remote control and four outlets in the cab. it fits directly to the roof of the cab usually in the roof hatch hole,  Unfortunately my Tatra does not have a standard roof hatch, As the cab was originally a military cab It has a gunners hatch.

Now, as much as i like the idea of a gunners hatch in my off road camper i feel that in reality there's probably no need for it. So i set about modifying it to take the air conditioner instead.

the hole had a 20 mm flange that sticks up from the roof in order for the hatch to fit over it and seal, i had to cut this off and grind it back to the roof level, the remove the hinges that were welded to the roof for the hatch.

Once the aperture was ready i made an adapter plate from 3mm aluminum that would  fit to the roof aperture and take the air conditioner unit.

This plate will be sealed to the roof with sickaflex and sealed rivets.

Roof Rack Started

I started on the roof rack, its purpose is to hold a couple of kayaks and act as a mounting point for some LED lights.
There wont be much room up there once the  cab air conditioning unit is fitted and the aerodynamic drag reduction system is fitted.
The will be a small amount of space for non mission critical stuff.

Windscreen protection.

I started on what i call windscreen protection, essentially its two steel bars that run vertically from the bumper up the front of the truck art the sides of the windscreen, they connect to the roof rack at the top.

The point of this is that any branches that would normally hit the screen will instead contact the steel bars and be deflected up and over the cab, effectively protecting the windscreen from the branches.

i started by removing the corners of the cab and attaching some 40mm x 6mm steel directly to the chassis of the cab, this only has to support the 40mm box section upright, i used 2mm wall thickness here to keep the weight down on the cab. Bearing in mind i will be adding two massive seats and two more seats as well.

the brackets on the cab will be bolted to the uprights with m12 stainless bolts and locknuts.  there will be a n additional bar going horizontally between the two uprights at the bottom of the windscreen, this will serve to mount some LED Light bars onto.

Cab Heater Finished

Today i finished the Webasto Cab Heating system. I fitted a 2000ST  2Kw diesel powered heater, as there is no water cooling on the engine an alternative source of heat is required.

I coupled the 2000ST to a MultiControl HD, its the latest controller from Webasto and enables the heater unit to be used as a ventilator as well as all the usual timing functions. It also looks pretty cool.

the exhaust runs through a silencer and out under the passenger side of the truck.

Steering Box Universal Joint

Whilst working on the dash, i noticed that there was a slight bit of play in the steering column. On further investigation i found it was the universal joint between the column and the steering box. \\It was a simple and cheap job to replace the UJ with a new one.

Dashboard switches finnished

Today with the help of my buddy Andy Linton (thanks andy) we managed to work out the complex hazard warning switch with its multiple wires.
Once again an old type Bakelite switch similar to the ones Noah used on the Ark.

It was the last one to sort out, so now all the dash switches are working and looking good.

Heater controls next, then that's the dash finished.

Here is the offending switch:



And here is its replacement, (far right)


Update, heater controls fitted.
