1969 Mack DM615TX steel nose

[Arnd]

Hallo all
Here is the start of another project. I hope to keep it running until it is finished with out heaving too big Problems and brakes. I was inspired for this by the TV series American Logger, I just saw it hanging on the top of restaurant and then started to search for this type of trucks in the internet. And after receiving a lot of information from you guys, thanks a lot, I would say that the right type would be MACK DM 611 SX. Please correct me if it is wrong.
It should be a tandem axel tractor for pulling logging trailers. I not sure about the capacity of and number of axels for the trailers now; I will have to talk to the Mack enthusiast up here, to know what will be possible with this truck.
I started the whole thing with an already started DM 800 kit with missing parts so there will be some modifications and many parts will come from the spare box, my own junkyard.
The pictures are not very well, sorry it was quite late last night and the light was bad.
Here are some first impressions of the truck
The start.




Now the first questions
Is it normal that the gab between the rear tires has to be so big? Can I use the rear suspension from the AMT Junk Yard Mack, too? I want to go with 22 inch Italeri cast spoke rims with standard Italeri tires on the front and heavy duty Revell on the back.

The kit includes two engines with two different transmissions. The V-8 would be too big for a normal DM. I will have to use the inline six but which? Mack or Cummins? Which one would be used for such a truck?

Thats all for now, hope to have some time this weekend to work a bit on the Mack.
So long
Arnd

Arnd,the standard engine for the DM 611 SX was Mack's own END-673E (inline six cylinder) standard transmission was Mack TRQ-7220 18 speed quadtriplex (two sticks) the spacing between the tires in the MPC kit represents Macks proprietary 65,000 pound axle configueration (very heavy duty) but the 34,000 pound Mack "Camelback" rears from the AMT kit were also available in the 1:1 truck................Hope this is some help to you! will surely follow this build,as a am a HUGE Mack truck fan/owner!..........................................Mark
