I like the way they look in that color. And sure like to see those old trucks running.

I found a couple of pictures of Matt's truck which could put some light on the matter of question. But seems like you have to provide the figuring out yourself.

Welcome! We like truck pictures and stories behind. If you have technical questions put them in the forum related to the subject. Plenty of info is already typed there either. So worth patient readng as a start. Vlad

T2070 has 0.60 top hole. The same for T2060 and T2080. T2090, T2110, T2130 and T2180 all have 0.71. That's why you would like faster rears if go to the most any multi speed transmission. Actually you should count T2070 as a 5-speed (T2050) with two crawl gears. The same for T2060 and T2080 with one and three crowls. They were designed for vocational jobs the most to eliminate shifs in traffic. The additional low speeds spreaded the use toward construction jobs when you operate a dump, mixer or concrete pump chassis driving in a city but need really low speeds for special tasks.

Ha-ha-ha! If you take that synchro out just send it my way

NO front axle had 9.02 ratio.

As far as I know at least one truck is in Europe. A guy from Finland imported it from the States. When I was a kid I had a picture of Big Horn cut from some old Russian magazine. It was small and black and white but I too liked the truck. Didn't know they were so few in number produced. I think the magazine was issued in 1977 or so.

Paul, those are very interesting files, put alot of light on the matter. Thanks. I see they note T2060A transmission in the list. Seems like it was done the same way (or even the same design?) as later T308 tranny. 6 speeds on the main stick require different top cover with one additional shift fork and a rail. All that seems done on T2060A. Wonder how the engeneers could put additional gear set into the main housing of the same size as a 5-speed unit had. And sure I wonder how the gear wheels are similar of the seating sizes to the shafts so I could take everything off two or three transmissions and play with until get dirty and upset. Let's see

That's what i keep in my mind. Originally my truck had T2090 and I would keep it but the sliding clutched got worn during the years of unexperienced driving. Locally I could find T2070 with 0.60 overdrive and put in the truck. Affordable but the gear spacing is up to 70% what is too much for Econodyne E6-350. Fast overdrive is good but one more gear between the direct and the over is required. My current idea is to try fixing the 9-speed using parts off the 7-speed but that newer 8-speed unit could make the deal too having the steps of nearly 60%.

Thanks the great Jim, that's what I was looking for. Interesting that the overall length of the transmission (798mm) is almost similar to T2090. The overgear ratio is also similar - 0.71. Definitely looks like T200 and T300 series have a lot of things in common. But too probably many parts of the content could be found different. Ok, my engeneering addiction gets my thoughts in direction of taking apart and combining/modifying everything I find on my way. This time its possible to install the unit as is since no modifications required to. The last point - I should find the reason

Your fabricator made a great job! At least as long as I can see it on my screen. So far I haven't found a shop which could made such 3D curves. The most of them are newly organized small companies with laser cutters and straight bending presses. Good thing they do exist though. Once again, thanks for the reference pics.

Good point on the bell housing, thank you. Actually the potential use is in a hobby truck. So not many miles are planned. This doesn't bring much worries on the input shaft cond too. As long as I know the engine was taken off just a week back. The matter of the rust seems the truck was parked with another issue (rears) for nealy 5 years as I was told. My main question at the moment is the ratios. Originally I had T2090 with 40% steps between the shifts and now T2070 installed with about 70% which is not what I like. So that unit with 6 speeds in the main box might be a compromize. Depending on the step lenthes and the top gear ratio.

About the same headach at me if anybody is of interest.

I am offered to buy such unit locally. The price tag is reasonable but I have no idea on the ratios, body length etc. It was removed from (as they said) 2004 DM dump truck with some kind of E7 engine.

Wow!! Looks much more exciting now! I'm sure you know what you do by my fingers will be kept crossed. What is the plan for that big 3" U-channel at the bottom of the back wall? Are you going to make a new one? Right at the moment I'm waiting for such part from fabrication but that one will be a straight piece. Hope to get it in the shape by cutting-welding-grinding. My new sills (or rockers?) are also in that order. At least I hope the shop folks will be able to bend what I have drawn

The thing I hope the most the truck will go to someone's collection being not taken to a set of really fresh parts or redone into a working horse to do commercial job as a tractor or dump.

On the other hand a day cab with that long wheelbase doesn't look like a typical MH tractor. And the milage is really small being proofed by the interior condition. They also announced a 18000 front axle.

That's really nice. Here special lights and sirens are property of the government services. And the authorities don't like concurence. As you know America and Russia are a bit different stories

In my country if you're going down the road with even DISABLED but still mounted red or blue light on the roof you would loose your licence for a year or two. Nice and interesting looking R.

By a chance I adopted a couple of pics of MH cement mixer from some trucks for sale site. It was Spanish if the memory serves.

Is that common to have a 9-speed transmission and a 38000 rears in a dump truck? Doesn't look like redone from a tractor but makes thoughts.

Ufff... Maybe it's nice when laying on a beach but I would better showel snow.

Ocassionally I found out that the most of Japanise heavy trucks use those 8 lug wheels. Here are many companies which import used wheels from Japan and for trucks either. I saw pairs of quite good 8.25x22.5 Alcoas for reasonable but had no need in them.

The picture "in red colors" (above) was taken by an owner of L-model firetruck whan he had an issue wth that brake light switch. That unit is relatively small, nearly 2.5" of the body size, a bit less than a quick release brake valve on modern trucks. Body has mounting holes and an airline attachment fitting of nearly 1/2" At the top of the body (looking at the picture) it has black plastic insert (plug) with two screws - wire trminals - sticking out. The most L-models have that switch mounted on the inside of the LH frame rail right to the right of the gearbox. The sopt you seldom research just using or basically fixing a truck. But if you investigate the area you will find it with not much efforts. It could be easily seen on the below picture to the left of the tranny especially if you zoom it in.

Directional light switch mounted on your steering column, you pull its lever when activate turning lights. Brake light switch is too probably mounted on the engine side of the firewall if your 95 Mack is model RD. Relatively easy to find since that's a kind of sensor mounted on the firewall an air line comes to and two wires attached to terminals with small nuts atop of. The switch is operated by air pressure when you apply the brakes. Sorry I have no idea on where such thing was located on CH, CL, MR etc since Mack produced many different trucks in 95. But i'm sure it operates the same way and its location could be found in the same area.
