Hello. I'm new to 5 tons and the forum. I never drove one until after I bought it. a couple weeks ago. So I'm trying to fix all those neglected things and am puzzled by something that was done to the truck long ago judging by the weathering. (1983 AM General M923) The air return lines attached to the front brake chambers (air line without the spring) were deliberately cut off but left attached to the frame and brake chamber on BOTH sides in exactly the same place. I'm wondering if I replace the lines I'll then find out why they where cut in the first place.
Also on an unrelated issue the automatic transmission seems to shift to early under load, 1400 rpm or so. Different on different gears. I don't have enough time behind the wheel to get a good handle on it. I'm thinking I should be locking out the shifting with the 5-1, 5-2, 5-3, 5-4 control when pulling a hill to force the engine into the power band and run it closer to the governor. I used to drive a 1964 White Constructioneer tractor with a 250 Cummings and a 10 speed Road Ranger grossing 92,000 lbs. It slowed down on the hills big time but it did it. The M923 is only 21,600 lbs with basically the same engine is a dog empty. I'm concerned if I throw 10 tons of coal in it it won't be able to get out of its own way.
