Which Ford disks go on top and bottom of the stack? Large or small?
Thanks

Would it not be the opposite of whatever the Watts discs are? I've never installed one, but I would think it would only make sense to keep them staggered large small large small, whatever the material.

It's been a while but as I recall, two large disks had to be used on either the inside or outside to get the stack height correct. So if you started with one, you ended with two and vice-versa.

It was just a few months ago, still can't remember what end the odd thickness Watts disc went.. Will check in the instructions when I get home. The Watts discs replaces the large Ford discs, small Ford discs are used in pairs in between the Watts discs as I recall. The last disc towards the push ring must be a large Watts disc to avoid oval push ring pin holes in the drive plate.

Another thing I remember from the instructions - the push ring pins must be shortened a certain amount. When I started driving I noticed the clutch slipped when I had the collar ring distance adjusted to 13/16" from the drive plate - had to adjust the screws half a turn twice to stop slipping.

On early (pre-’16) drums: Install the special Ford thick steel spacer disc first, then one Watts disk, then 2 original “small” steel disks. Repeat with another Watts disk, then 2 more “small” steel disks, and so on until you have installed all 8 “small” steel disks and all 5 Watts disks. The thin Watts disk must be the last disk in place.

On later drums (1916-27): Install thin Watts disk first, then 2 steel disks with inside notches, then a thick Watts disk, then 2 more “small” steel disks, until you have installed all 8 “small” style steel disks and all 5 Watts disks.
NOTE: Some later (‘25-’27) drums MAY require the first Watts disk to have its corners filed to allow the disk to go all the way through to the surface of the drum.

Thank you that is just the information I needed.

The easiest way to check to see if your drum needs the spacer or not is to install the thin Watts disk first, then try to get it to slip sideways, out from under the drum lugs. If it will do this, you have an early drum and need the spacer.

If there's enough demand for them I may make some.

Mine is a later drum but I will check. Speaking of spacers, I went through my stash of parts, I still have 3 of them. Something I will hang on to, never know when I might need them. :-)
