I have acquired some 28 non emergency brake worm drive internal parts that I cannot use:
2 wheel bearings (i assume? look like wheel bearings but smaller diameter and longer than my 29's worm drive)
2 axle shafts ( teeth look great, axle nut threads are great, taper is good, kinda gooey sticky but not much rust)
carrier with 2 spider gears and cross shaft (appears good, spider gears look great)
worm gear itself and bearings for it, also short maybe foot long splined drive shaft attached, very little wear on any of it
worm ring gear, has wear and very tiny chips on the tips of some teeth (chips are way smaller than a pin head)
Thats the major stuff I can think of at the moment, I rescued this stuff from a guy who sold his AA truck and was going to scrap these parts that have plenty of life left in them so I'd like to sell/trade them to a good home.
I can get pics of the stuff but will have to be next week.

Re: 28 non emergency worm drive guts
how can you tell? count number of teeth? Only way i know is to spin axle or worm X number of times to get wheel to turn once, i suppose i could mock that up.

Re: 28 non emergency worm drive guts
Shoot, I know when I compared the worm with my known high speed 29 it has less teeth on the worm which would make it 4 tooth I would guess...
Well sorry for the "bad news" as i know the low speeds are rather unpopular. Looks like its destine for a doodle bug.
