b61fred Posted September 20, 2005 Share Posted September 20, 2005 Hi, I have got my new prize home and started scrapeing off the greese and crud and finding numbers on the engine, trans, and axles. The engine is a NH220L cummins, the trans is a 15 speed triplex, the front axle is a 9500# with no brakes, any ways the rear tandem is not Mack it is a timken worm drive with power divider, 7.45 : 1 ratio, Is this factory?? it looks like it belongs there and also it needs some work on the bushings and rods that center it in the truck, where do you get such parts?? I never seen a old mack with anyting other than a mack rear. I have sent in to the museum for the info but that will take some time to here back from them. the truck was from montana, It has a jake brake and a exhaust brake, Let me know what you think Fred Quote 15 gears...no waiting!
