I built the driveline this weekend. I had to remove about 6” from the front shaft and weld on the new 1710 series yoke. This thing is huge!
I measured a 5” drop in 74” from the centerline of the crankshaft pulley to the centerline of the output yoke on the old transmission. Since the bus has 3 sections of driveshaft, I gave the center section the same degree of drop which also matches the rear pinion angle. No vibrations, weird sounds, or heat from any of the u-joints or carrier bearings. I need to change the remaining 3 u-joints as they feel pretty rough. They each took about 8 pumps of grease before they started oozing.
We took it for a short test run and it is so much fun floating through those gears! I found out that it will take off just fine in 3.5 gear (low gear, high range). This means that I will likely drive it like a 5 speed using only high range in normal conditions. I’ll have 6 additional gear choices if I want to go slow. It creeps in low-gear-low-range-deep-reduction.
