Bendix air pump replacement

[Jay Darst]

Haven't noticed any water or oil in the tanks. Replaced the governor
about a year ago. Serviced the dryer as well. The dryer looked like
it had a fair amount of water and oil mix in it. Looked like a milky
vasoline or similiar...

The governor did prevent the air pressure from reaching normal 135-
140psi, it would get to mnaybe 75psi.

Takes about 15 minutes to air up.

Detroit. Speedo says 48K miles so we'll have to assume the hours is
the correct indicator... probably has 135,000 miles on it now.
