Packing for Hershey and need to know how many disks are in the early 1928 MULTI DISK clutch stack. I call the ones with teeth on the outside OUTERS, and the ones with teeth on the inside INNERS, I know one on the end is slightly tapered. Hope there are people looking for these and other NOS AR parts. Thanks for the info.:)
 
I will count the discs on the one I have this afternoon. If you don't find a usable one at Hershey send me a PM. Going to try to get the one I have apart next week with a home made compresossor. When I had the 28 rdstr pu I made a decent one from 9 used clutches. Sols my compressor last winter as I did not plan to mess with them again. Got what looks to be a nice one in this last pile of parts I bought, will confirm it shortly. Rod
 
Thanks! If you want to borrow my K.R.Wilson compressor all you have to do is cover postage both ways. Bob
 
Thanks for the offer, I may take you up on that depending on afew factors which I should have resolved by the 15th. If I end up sending my brake shoes to Bert's for arching I will likely try to borrow theirs, so atleast there will be parts in the box each way. I think I am getting close to finding the right clamp for brake shoe sander, so will let you know. Rod
 
Driving and driven:
The series of disks that make up a multiple disk clutch are divided into two categories, the driving disks, and the driven disks. There are four driving disks; each has outer teeth that mesh with the inside teeth machined into the flywheel. Both sides of the driving disks have a composite clutch material riveted on. The material is the same as used on a single disk clutch. The design provides eight sides of composite clutch surface. The driven disks are made of saw blade material and in fact look much like a circular saw
blade. There are five driven disks. The inside diameter of these disks have teeth that mesh with mating teeth machined on the clutch assembly drum that is attached to the input shaft of the transmission. The driving and driven disks are alternated in the assembly providing a metal surface for each side of the eight composite surfaces to rub against. Henry's killer spring tightly sandwiches them together whenever the clutch is engaged.​

One of the driving disks has a notch in one of the teeth. This disk has different dimensions and goes at the head of the stack. For a complete description of the mult-disk clutch go to www.ocmafc.org web site. On the menu at left click on "tech articles", it will pull up another menu. Click on "Tom Endy's articles" and it will pull up another menu. Go to multi-disk clutch and click.

I use about a 15" piece of 3/8" threaded rod as a spring compressor to take the clutch pack apart or put it together. I use a pair of screwdriver shafts to align the discs as I tighten the pack when reassembling. This works fine.Just remember the notched disc is the one closest to the ****** when assembled.
