    Merkabah: MB 2626 AK 6x6 tipper to expedition truck conversion

    Good to hear all is good with you and Merkabah is still progressing! I took a punt and went with the center of the chassis for the twist point as it seemed to be pretty close to it with a basic frame test. I then tacked the two pivots in place and twisted it using a jack and blocks. it all...

    Mercedes 1222A.. The beginning!

    If I had the space for two fuel tanks, I'd run the original tank as well as the large semi tank I now have. Working on where I can hide water tanks so I can do that. I have provision for 100lt of diesel in jerry cans.

    Mercedes 1222A.. The beginning!

    Hi Jason. Yeah, it's coming along. Re chains, in all the places I've been, I've never had to use chains... but it is a good point. The rear arch shape is a copy of the front, so in theory if chains would fit the front on standard tyres/arches they should fit the rear. As for the...

    Mercedes 1222A.. The beginning!

    Here it is bolted in place. The beginning of making the whole thing look like it was meant to be!

    Mercedes 1222A.. The beginning!

    Lastly to finish the surround and outlet. How to keep the outlet pipe flush and tidy.... Make it rectangular!! I think it's worked out well. :)

    Mercedes 1222A.. The beginning!

    Next was to weld up all the tacked mountings for the muffler box, and complete the surrounding 'tinwork'... Some of you will have spotted the large piece of RHS... Yes, this is the inlet to the exhaust muffler. I had to work a way to get the gasses from the gearbox area into the muffler inlet...

    Mercedes 1222A.. The beginning!

    With the muffler box in place I could start fabricating the 1mm steel around it to make it look like it should be there, and form part of the finish skirts.. This also involved making a new mount for the cab tip pump, so it's closer to the outside of the truck. The slot and hole in the skirt...

    Pneumatic clutch assistance.

    Hi Niel. I'd be looking to see if the clutch save cylinder on a 1222a is interchangable with yours... Mine has a 6 speed box in it, and the clutch slave cylinder is air assisted. Clutch won't go down until the air pressure is up, but once at pressure, it is very light (car light). I'll have a...

    Mercedes 1222A.. The beginning!

    On with the build! Last night I couldn't be bothered to do anything noisy or productive, so I cracked open a beer and pottered about! Out came the cardboard. Time to work out the depth of the side skirts and shape/size of the rear Jerry Can and recovery gear lockers... With a 100mm gap (black...

    Mercedes 1222A.. The beginning!

    Sooooooo.... Question time. I have to chop the rear 600mm/24" off the chassis, which includes a nice factory riveted rear X member. I plan to reinstate the original rear X member flush with where the inner stepped section of the body finishes. This will put it approx. 1m/40" behind the rearmost...

    Mercedes 1222A.. The beginning!

    And here's the picture of the chassis twist (Approx 50mm/2" up on the left rail and 50mm/2" down on the right rail). It should be noted that I can remove the pin locking bolts and tap the pins back and forth in the newly fabricated carriers, so I think I have the pivot points in pretty well the...

    Mercedes 1222A.. The beginning!

    With both mid mounts in place, ideally I would have taken the truck outside and cross axled it on a few soil banks, but at the moment I have every air line from the battery tray/air tanks disconnected as I'm shifting the tray and tanks under the Pax door to give me more room for other stuff on...

    Mercedes 1222A.. The beginning!

    With all 4 droppers fabricated and welded, it was time to move one poorly placed body X member (hard to plan this far ahead), and add 3 more. Once I had 4 X members in place I could position and tack the 4 droppers in place using the pivot pin to support and position them. Here is the first of...

    Mercedes 1222A.. The beginning!

    Next was to cut, shape and assemble the 4 'droppers' from the body to the base plate... which kinda went like this!

    Mercedes 1222A.. The beginning!

    I've fabricated two of the base plates so they utilize two cross members on the chassis. The two that are linked directly to the spring hanger mounts of the rear axle. I figure that having the body supported on cross members that act directly on the spring hangers then leaves minimal load/stress...

    Mercedes 1222A.. The beginning!

    Those RHS supports will become part of the body, which will pivot on 2 (poss 3) of these base plates. Grease nipples yet to be fitted.

    Mercedes 1222A.. The beginning!

    Another weekend, most of it 'playing truck'. I have managed to get the body sat on 4 points. Here is the start of the process. The diagonal supports.
