mumblymack76 Posted March 30, 2009 Share Posted March 30, 2009 This Mack DM 800 tractor is listed as the #2 off the line and the first of its type sold to the public. Could this be true? It seems to need quite a bit of work. I searched under Mack DM on ebay search but here is the link.http://cgi.ebay.com/ebaymotors/1967-Mack-D...ercialQ5fTrucks Quote Link to comment https://www.bigmacktrucks.com/topic/8833-rare-mack-dm-800-on-ebay/ Share on other sites More sharing options...

Would be a little concerned why it was taken apart and not finished?Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

HK Trucking Posted March 30, 2009 Share Posted March 30, 2009 They should take out the Allison Automatic and just sell it without a transmission.I'm sure the truck would bring a better price that way.

Superdog Posted March 30, 2009 Share Posted March 30, 2009 If the VIN is correct,it would have originally had a 237 Maxidyne,so that really doesn't make it that rare.

jeffbyrne Posted April 1, 2009 Share Posted April 1, 2009 DM 865 SX ? I think 65 would be a cummins, a 237 would a DM 885, a GM would be DM 87x I think. Most Cummins engs are in the 6's. It could be a typo. Pretty early DM . There was only about 25 DM 865's built between 67 n 73...

Hey Super, I got a pair 6 mths ago, I hate them. But that DM, I had to look twice, cause I had Maxi V8 in my head because of the 865...

David Posted April 5, 2009 Share Posted April 5, 2009 Does this VIN mean it was the second DM800 or the second with a Cummins? Do all VIN production numbers start with 1001?

David Posted April 6, 2009 Share Posted April 6, 2009 Anyone know how the VIN's are assigned? I am buying this truck and debating on installing a 865/6 or a Cummins. The first thing to go is the kangaroo killer. The second is the 12v71. Rob, let me know what you need for your project, maybe I can recoup some of my investment.

The first thing to go is the kangaroo killer. The second is the 12v71. Rob, let me know what you need for your project, maybe I can recoup some of my investment.Hi David, I'm thinking that my 12V-71T is ready for the conversion. I've bought two 8V-71 engines for the needed ancillary parts like sheaves, brackets, and such. My engine has twin turbochargers and if this one is turbocharged, I might be interested in the engine complete, no matter the condition. I would like to relocate the turbo mountings on my engine is possible.I can't say for sure on vin number assignment. I have my 73 RL797 and the serial is 19001. It is verified as the first RL797 built.Did you do anything with the DMM that was burnt?Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Superdog Posted April 7, 2009 Share Posted April 7, 2009 Starting sometime back in the late 20's-early 30's,the first built of each model was #1001.The exception to this seems to be with the trucks built in Hayward,CA.They evidently just got numbered in sequence,no matter what model.Take Rob's RL797 for example,it should have been RL797LST1001,being it was the first of it's kind.

It is a 1978 Model.Both were produced at Hayward, CA.They musta done things a lot different out there.....Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

B66 Posted April 7, 2009 Share Posted April 7, 2009 Hey guys, after reading this post, I had to confirm something. After working all day I went back to Building 3 at the Mahan Collection to see the DM in the collection, sure enough...DM865SX1001...yes that's correct, the first one off the line. I asked Gary and he said I should let you folks know that there was a 1001 built and sold to the general public. I'll have pics to post tonight.

David Posted April 7, 2009 Share Posted April 7, 2009 Thanks for the VIN info. Rob, the burnt truck is also a DM800. It has a V8 and 12 sp. It also has a lot of parts to complete this project.

Are you going to use the Allison, or go with the 12?Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

jeffbyrne Posted June 30, 2009 Share Posted June 30, 2009 Does this VIN mean it was the second DM800 or the second with a Cummins? Do all VIN production numbers start with 1001?I think it means the 2nd with a Cummins something,from what I can gather if it is a B 615'T' 1001 the next one could be a B 615 'ST' 1002 then 3rd could be B 615 'SX' 1003 there could be ten all the same thru to 1013 then there could be a B 615 'X' 1014 but it would change if it was a B 61'3' T eg 1001 B 61'3' ST 1002 B613'SX'1003, so long as its a B 615 or a B 613 or a DM 865 I dont think it matters what it is behind the cab. Thats what I reckon. Regards Jeffro . Quote Link to comment https://www.bigmacktrucks.com/topic/8833-rare-mack-dm-800-on-ebay/#findComment-37400 Share on other sites More sharing options...
