I am installing smart tire on the bus and thus am taking the tires off. Have found quite a mess there and am cleaning it up.
Something I am having trouble with is cleaning the valve stem pocket found on the outside of the wheel in the dished area. It is very dirty and corroded and needs to be clean to properly seat and seal the stem.
The best way to see it is with an inspection mirror and a magnifying glass. I am wondering does anyone know of a special tool for performing the task and where to get one. Something that fits the hole and attaches to a drill with maybe skotchbright inserts or what.
After removing a wheel I found a leaking tag oil seal. and learned about wheel wear on the mounting flange.
Lots of work to get these buggers into shape.
