It is missing the two external cone shape rubber drive inserts. As old as this is I understand them missing. Anyone here have an idea where I could purchase replacements?

I pulled the concave rubber drive out of the metal driver, turned it over, stuck it in the freezer in my garage. Chucked it in my drill motor and held it against the turning grinding wheel of my pedistal grinder. Will work till I find rubber stock. Thanks [Reply]  [No Email]

I just stop at any good hardware store and buy rubber plugs/stoppers. I then trim them with a utility knife to about the size I want. I then finish them off with the screen type emery cloth. I usually get them to fit tight enough that they will stay in without any help. If I get one that is loose I just clean everything up and silicone it in. Let it dry and trim the extra off.

I have found somethings they don't quite carry. I needed a radial spring for my JD LUC carb choke. They didnt have one that was exact enough. I ended up going to a piano repair shop with my calipers and got the correct size of piano wire and made my own. [Reply]  [No Email]

If so I get them at my local New Holland dealer. Same size fits in 8N Fords. [Reply]  [No Email]

If it was mine I think I'd start on the pages of the McMaster-Carr Supply catalog and see if they have anything rubber that is close to what I needed, might find some O-ring stock or maybe even one of those funky round rubber belts, rubber extrusions, some kind of packing or round gasket stock.

But, how about some RTV in a tube and kinda shape it before it sets up? ohfred41 [Reply]  [No Email]
