I am using the same hub that Wayne Schell and Jim Shepard used to drive the enging to right angle box. This way the pullys can be moved in and out to get the best alignment. These are not available so I made it close to their design.

I decided to use a right angle box from hub city. The Eagle factory box is much lower hp rated.

The drive shaft came in at 20" which is a few inches longer than the old one. The 4000 allison is shorter that a 740 which allows the longer shaft. The tranny comes with an 1800 series yoke which is bigger than the 1700 the bus came with. We may need to turn the rear yoke down a little for a little more space.

Nice work Eric.When I but the new drive shaft on my 05 the blue plastic grease cap was a little to long when the drive shaft was at a steep angle. ( would only be that way when you go over a bad bump) I took it off and turned a shorter one made of steel one with a hole in it and tack welded it in place. But you must be sure the inner shaft has a place to go when it is at its shortest point. You mite want to look at that when you tear it apart.
Your project is like the monkey that got his tail caught in the meat grinder it won't be long now.

I think this thread is getting out of hand and needs to be reported to the moderators - oh wait, I am a moderator :D :D :D :D

Eric, I like your crank shaft adapter. Building that shoulder looks like it would add a lot of strength. When I drew up the one that Wayne made, I made sure it was hell for stout. Then when Wayne made it, he beefed it up a bit more.

He made one for both of us and I really like the way it worked. It sure made it easy to mount industrial pulleys (with their bushing system).

Wayne needed a serpentine belt pulley for his application. His used a "K" section belt and there are no industrial pulleys in that section. I gave him the pulley groove drawings and he took an industrial pulley and had the regular grooves machined off and the new groove machined in.

I have talked to another person who took the DD serpentine type pulley and bored it out so that it could be mounted on an industrial pulley that had been machined to the mate with the bore.

I am going to mount my leese Neeville 270 amp alt. on the right. It has std v belt so I can use a 2 pc hub on it. I think the hub is the way to go for alignment also.

Eric, as you know, there are two hub systems for industrial pulleys (I think the strange Browning hub which would be a third system is no longer made). They have the trade names of Taper Lock and QD. The QD has a big flange on the side of the pulley and does not work well on this application if you mount more than one pulley on the crank adapter. The Taper Lock hub is contained within the pulley and does not add width. Any good full line power transmission distributor (Motion Industries is the biggest) will have both types of pulleys in stock.

The pulley on your alternator will probably have automotive grooves and they are different than industrial pulley grooves. The Leese Neeville will likely have a straight shaft (not tapered) and you can install a bushed industrial pulley on that shaft. I would use a 3 groove 3V system. Assuming you have 3V sheaves on both ends, you can use a joined belt (Gates trade name is PowerBand). That will make a great drive.

On the 10, Eagle used 3 each 3V belts to drive the big alternator and industrial belts to drive the fan. You just need to be careful if you try to mix the automotive and industrial systems.

Let me know if you need any help with the belt drive (did that kind of work for Gates for 34 years).

Idler pully from motor to right angle box.
I am using a combination of the Eagle 15 and 20. The pully and arn are for a 15 with a series 60, and the air cylinder is from the ac side of a model 20. I will also have a spring over the cylinder to keep pressure when the air is down.
