Hey everyone, new to stovebolt. Recently purchased an awesome 42 chevy dump truck that has set since 1959. Drove 5000 miles round trip to pick it up in Great Falls Montana and bring it back to NC. Having a great time bringing it back to life. Found that the flywheel gear had broken, possibly the reason it was parked. Originally was red with black fenders but has been painted military green at some point inside and out. Don't know we're it severed but assumed it was used state side during WW2. Still quite a bit of green on the interior with a great mixture of red, black and green outside. On my first stop on the way back I took the oil cap of and filled the motor with diesel until it ran out of the canl vent and pulled the plugs and sprayed the cylinders wit PB blaster. Got it back when I rolled it off the trailer, popped the clutch and it turned over. After some wiring and a new battery found that the flywheel gear was broken. Tack welded it back to the flyw3 temporarily to see if I could get the motor started. After unsticking some valves, carb and fuel clean out and a tune up it fired up, runs great. Pulled the tranny and replaced the gear, clutch, pressure plate and throw out bearing.. Now it moves on it own for the first time in 60 years. Just started on complete brake rebuild. So after all of that this is my first question I hope someone can help me with. It has a two speed axle that is shifted with a second shifter by a cable. Not sure how to use it. Know about electric shifters but not these.. Do you shift the same as an electric? Shift on the fly up and down as you would a later model axle? Don't want to tear up the rear grear. Thanks for any info you might have.
Hy Gulfsuper, welcome, that sounds like a great project you have there. Am I correct in my assumption that your truck has a Timken double reduction two speed differential? I have seen those differentials shifted by rod linkage, cable linkage and vacuum diaphragm, but I have yet to see an electric shift unit. Good luck with the rest of your work.
Thanks Master Gabster. Believe you are correct on the double reduction. Do you shift it the same as later two speed axle? It has a four speed gear box. Do you change the axle as you go through the gears?
