67RModel Posted October 22 Share Posted October 22 Didn't know where to put this one. Here or in the for sale section. This 1973 400 series DM is coming up for auction in a few weeks. There is actually a pair of them this 73 and a 74 but they are specd the same. They are DM487Sxxxx. I don't think I have ever seen this engine before. I think this was well before the times you could get a Scania so what is this? Also these trucks have a strange Eaton 13 speed I have never seen before. They actually have 15 different gears but 13 progressive.

Solution The Heinz Posted October 22 Solution Share Posted October 22 (edited) I'm getting good at figuring these old Mack VIN's out. According to Impact, it shows to have an ENDT475 SCANIA in it.

Mark T Posted October 22 Share Posted October 22 That's a little tiny direct 15 speed. Probably called a thirteen cause a couple of the LoLo ratios overlap with ones in low range.

mowerman Posted October 22 Share Posted October 22 I’m thinking it’s probably that shifter with the chrome round dome with a three speed switch and yes, it does look like a Scandia. I didn’t think they were using them in those years either, but I have seen them and R models.

Mark T Posted October 23 Share Posted October 23 That sticker is way newer than the truck. Quote Link to comment https://www.bigmacktrucks.com/topic/74669-what-engine-is-this/#findComment-560577 Share on other sites More sharing options...
Brocky Posted October 23 Share Posted October 23 The 6613 I had attached to a 555 Cummins, not in a truck so no stickers, had a splitter box on the back like a 9513.. Was told when I bought it, it was and underdrive splitter??? Came out of an asphalt oil distributor / sprayer truck.. 1 Quote Brocky Link to comment https://www.bigmacktrucks.com/topic/74669-what-engine-is-this/#findComment-560589 Share on other sites More sharing options...
67RModel Posted October 23 Author Share Posted October 23 That is interesting. Honestly, that engine doesn't really look like the other Scania engines I have seen in Macks before, which have been very limited. The ones I have seen in early 80s R models If I remember correctly had 3 separate heads. This version seems to have a single head. Also, I thought the Scanias were a late 70s, 80s thing. Didn't realize they existed back in '73. Interesting. Those two DMs would be neat to have just because of the uniqueness of them. The frames and chassis are in near perfect condition and they will probably sell for next to nothing. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74669-what-engine-is-this/#findComment-560593 Share on other sites More sharing options...
The Heinz Posted October 23 Share Posted October 23 As for the transmission, it was built with a Fuller RT613. Forward drive diff is a CRDPC921, rear is a CRD931, both in 5.13 ratio. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/74669-what-engine-is-this/#findComment-560596 Share on other sites More sharing options...

Vladislav Posted October 25 Share Posted October 25 That steering shaft adaptor on the steering box looks like was specially designed to clear the turbo tube. A factory part definitely. Don't remember seeing such ones on DM's. At least of 600 series.

Terry I used to see a double U-joint link with an angled steel bracket. But I mostly saw later DM's. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/74669-what-engine-is-this/#findComment-560900 Share on other sites More sharing options...
