The seal sits in the cavity of the wheel shown with the 4 locating pin holes. The seal has the pins so that it does not spin with wheel rotation. The springs force the seal against the wheel and the flange that carries the pin. This seals the end of the pin from dirt and allows for some motion between the flanges. It seems to seal two opposing surfaces allowing for the motion noted rather than the OD of the shaft. I like your delrin idea and can add pockets and springs. The key are the bellows to seal between the 2 faces. Maybe some cut cv boot but then tying that to each delrin piece=ugh

Yup, I think he's on to something with the delrin as well. Delrin with O-ring grooves and possibly rope on the ends...

I would really need a bit more info but trying to seal a flat surface that is rotating is not ideal . If the wheel is on a fixed shaft, it might be easier to fix the seal housing to the wheel so it rotates with it then use a conventional type shaft seal to seal on the shaft . These types of seals allow for both rotating and in and out movement . This way if you only need to seal the wheel, whatever you use for a seal housing does not need to extent to the opposing surface.

If you need to seal both opposing surfaces, you could also possibly make 2 seal holders with a spring in the middle and a torrington bearing on the side that needs to rotate with the wheel etc.

I considered both of your suggestions. A simple seal like a rear main seal would be easier but because of the dirt and abrasives that can pack in the hub, I assume that is why this bellow type is used. I'm your second design which is similar in scope, they just used a flat bronze washer to scuff against ( once again due to dirt and silt etc). Thank u for your ideas

Mama mia! That thing is in nice shape!

[3 Wheel Drive]

It has not been started in years, im the 3rd owner. The previous owner only admired it, he never started it up. It feels like it has tons of compression.

I had the original title from 1971 but the WA liscence kept it. But they gave me the faded carbon copy. The
odometer reads 300 miles, from the condition it looks like it too. The original owner told the previous owner that he rode it from Seattle to Portland once, thats 173 miles.

The inside of the tank is just as clean as the outside. Previous owner never put fuel in it because he didnt want to varnish up the carb. Im going to inspect it before trying to start it up on a grassy field, lol.

It weighs twice as much as a Honda CT70.

That's a neat story

Not as cool as a Benelli but I took my little Yamaha to the weekly cruise night. She was missing a few items so I couldn't ride her there.

Heres the start of my QA fiddy rebuild, Ill probably start with the auto clutch then replace the bearings.

I just uploaded this vid on youtube, it basically only drove in first gear because 2nd slipped very bad. I got all new gears and pawl to replace the old ones.
