Here is much cheaper to weld a drive shaft using two different halves with different forks and than balance it. At least so far and if you have the parts for the conversion.

I found it. Not them though. I found some web-store with rubber insulators for small van-boxed trucks. They offered cheap and described as for 2 inch straps. I bought two rolls from them and when recieved found out they are actually for 1.75. With the comment "they could be used on 2" straps"!! Unfortunately when cutting SS strips I ordered them 54 mm, not 51 as I should for two inches. So those rubbers being possible (too hard and not nice) to put onto 2" strips have nothing of intend to fit mines. So now the search continues.

Real Siberia this time. Khanty-Mansi region. RD690S. The year is unknown. It was an oil field truck, some equipment carrier. The company drivers broke one of the differentials and found reasonable to take the truck out of service and put the equipment onto something else. The odometers showed 45K miles. Not sure that's true but see no reason for anyone to turn it back. A bit later a guy ruined an engine in his IH cabover and looking for the solution he bought Mack and put EM7-300 off it into his truck. Still messing with attachment of some minor air lines etc. After that he put an add to sell the rest. Happily he didn't scrap it immediately as many folks overhere do in such cases. It took me almost a year to work the deal out. In the beginning I had to wait no less than 5 month to see some pics more than he originally posted in the net. Than I was told there will be some trucks getting loads from near Moscow so chance to bring it my way appeared. After no less than a month I got some more images of what I was intersted in. At the same time I asked my friend with old Scania to make a road trip. He, being an advanture lover, was eager to help. But the owned resolwed to get a summer holiday to Black sea. For more than a month... Just a week ago the things started to get in order and yesterday I finally saw what I was payed for Had to order a straight truck with a crane since I can't come to my property with a semi. Too tight spot in the street. A plan is to use it for parts. A rust-free cab with decent doors and some of good interior including heater/AC. T2070 gearbox which I was looking for to put in my R for more road speed and less shifts since it's planned as a single truck. A complete bogie on camelback with two 5.73's. Very solid rust and split -free frame which I have no plans for. The same for a newer RD hood and probably radiators. And what is misterious about that truck is someone put Marmon-Herrington front drive axle together with M-H transfer case to make it 6x6. The rears setup is also a kind of "high level engeneering". A frame cut-off with bogie and two pieces of frame rails (off some DM looking for the rails section dimentions) were put right below the original frame and attached with two 3/8 fish plates. Probably for a good clearance or just to level the rear end with the front. If anybody is familiar with such Marmon-Herrington fronts and transfer's I'd like to know their original use. I will probably scrap them having no need in but would be much more pleasant to get a bit of coins finding a person who might have use for them. Vlad

Keep on progress! Looks nice so far

An eye-catcher! As for Tonny Champion it would be much cooler to paint it original way indeed. I'm not familiar with what Ron will say on that matter this time, but in older discussion he stated that's the same truck.

Ja, Ich verstehe die "balltasche". I'm just difficult figuring out what a "balltasche", a man and a door handle have in common??

Paul, thank you for posting that. Looking over the setup on the truck I got figured in general how it works. The said above I meant the truck is not running so I had no experience of how those brakes are good or bad on the road. Relating to the common air style.

Das kann Ich nicht verstehen!

Any suggestions on the origin of the fuel tank? It doesn't seem stock to a F-model. Also what is the can in front of it? Air start tank?

That's right!

Paul, I'm afraid I spent not enough time in NYC to figure out some slang speech figures And Google seemed wilted to help.

The axle with the brakes of the style you describes is fitted in my DMM Mack. And it's a standart factory equipment. Discs with hydraulic calipers. And damn air/juice mixed setup on the left framerail to activate it. I have no knowledge of how it actually works though. The truck is not running.

Candy! If I were you I might be disappointed of what the holes to put bolts in fitting the bogie stand. And a question. How did the stand and the crossmembers relate to the alu rails about the width? Were those parts off a steel frame?

Being at my neck of the woods I'm difficult to became an expert. But from what I saw in multiple Mack sales brochures both trucks with rectangular and round horns were avalible at the same time. Talking to original rectangular horns they were made by Hadley. If Mack sells them there is the sticker almost applied on. If you buy from Hadley dealers the script "Hadley" is right there. And you can buy the sticker from Watts for $1 to make it OEM look. Doesn't save the cost though. Sure in both cases the brackts are included.

From Wikipedia: Escutcheon is an old French word derived from the Latin word scutum, meaning a shield. Hope I will be able to keep that in my mind for more than a minute.

Lesley, are those ones look the same as originals on your truck did?

I'm not for Dolly, I'm for the Superliner. Regardless it's blurry it looks great! Maybe that was the reason they loaded it with lumber of some special sort, not like the red truck had? Thank you for the pictures.

If you have asked me I was able to tell the size since I already had it in a copybook. If I were online though So now I see it tells 810 mm at the outside from the front edge to the rear. At its lower area. The measurments were made on DM truck and it was in the Nethrlands. And the temperature was almost nearly the freezing point. Is that the reason the size differs from what it was in Australia?? And yes, they are similar to ones on a R-model. I already have a pair of them put on my R. Hell, They weren't from DM. It was DMM!!!

Thank you for explaining that. Sounds easy to figure out and keep in mind.

Steve, I suppose it's not too easy to find a chat on B-model's carriers with teeth counts on every gear setup. Seems to me much easier to remove the big side cover on the carrier. It allows to cont both bevel wheel and pinion. In my case I have 9.02's and will have to use my original lower sets due to the design. So the upper ones is the only game to play. In very theory your lower sets might be slower than mines. If so I would achive something faster than 7.49 you have now and it seems good. Although IF you will be so eager to spend time removing the covers and count teeth, and IF the cound is good, I will want you to take the diffs apart and send me the gear sets only. So I'm afraid I'm too cantankerous buyer in this case Vlad

There's also difference in rear hubs. At least the ones with 8 stud shaft flanges exist (small flanges) and the six stud larger flanges. With different bearing inside. I supposed to see big hubs with cast banjo's and small ones with stamped steel (fabricated). But recently found on at least two RD690's fabricated banjo housings with big 6 stud hubs. And if the difference between 34K and 38K is springs only how to determine it for an air ride?

This worth the "Best answer" award!

Wonder who made those diamond-plate aluminium battery box covers? Were they ever offered as a factory option?
