tjc transport 418 Report post Posted September 3 Tulsa manufacturing and Marmon-Herrington are two that i know of. as for cost, it would probably be more than the truck is worth 1 Share this post Link to post Share on other sites

Jamaican Bulldog 27 Report post Posted September 3 Maybe an ex- municipal single axle 4X4 RM plow/sander truck may be a good donor. It may be easier to convert one of those to a dump rather than vice versa. 1 Share this post Link to post Share on other sites
Lucky dogg 3 Report post Posted September 9 Hello, I am into doing this. I am currently making a b model tandem 4x4. You will need to located a front axle with the same ratio as your rear pig first. You will also need a transfercase. Lxq is a place in toledo Ohio that's has alot of these things. Fabco is a good manufacturer to work with. If your savey with parts you can keep an eye on ebay sometimes people list these things. The transfer case is usually air selenoid controled. You will need a good Mechanic / fabricator to assist in this project. You will also have to have someone redo your drive shaft for rear and front. It will probably cost more then it's worth, however-- if your like me my stuff is never worth anything except what it's worth to me. When I want to buy something it is always top dollar. My feeling is sometimes being satisfied cannot hold a true cost. But if you Penny pinch and are patient and get the right parts and take your time it for sure can be done. Manders diesel is a great place to check out also. Keep in mind ritchie Brothers and Manders always are trying to sell wrecked or totaled trucks (4x4 bucket trucks ect) one went last auction for $2800 bucks. The transfer case was worth more then that. Good luck! 1 Share this post Link to post Share on other sites
Vladislav 1,901 Report post Posted October 7 By chanse I have both front axle and transfer case Marmon-Hrringtone made off 1991 RD. Can't tell the ratio right at the moment but the rears were 5.73. Too suppose my location would give frustrations to a person who's looking for such setup at West side of Athlantic. Share this post Link to post Share on other sites
fullfuel01 353 Report post Posted October 7 I have a Mack RM 6x6 if it can help you. We also have DMM mack with transfer case and front driving axle but the ratio will need to match your rear end ratio Share this post Link to post Share on other sites
j_martell 415 Report post Posted October 7 There's a handful of ex-mixer DMM chassis (8X6) sitting at Vision Truck in Cambridge (former Cambridge Mack)....they've been there at least 5 years, not sure what they're doing with them. Share this post Link to post Share on other sites
