Converting Standard COATS ® 40-50 Tire
Changer To Nitrogen Tire Inflation
Before beginning this modification or attempting any
maintenance, remove the air source from the machine;
also, bleed off any stored compressed air by exhausting
through the air blast foot valve.
Tools Required: Speed Handle, 3/8-inch Socket, 9/16-
inch socket, Spinner Handle 1/4-inch, Knife, 12-inch
Adjustable Wrench.
1. To start, remove both the front and rear side pan-
els from the machine. This requires the speed handle
and the 3/8 inch and the 9/16 inch sockets.
2. On the front side of the machine, remove the infla-
tion pedal by rotating the pedal upward and sliding to
the left.
3. Remove the nylon tube from the repeater valve by
pressing the brass tube furl toward the fitting and
pulling outward on the nylon tube. The opposite end of
this tube is attached to the 1/4-inch brass poppet infla-
tion valve.
4. With an adjustable wrench, loosen and remove the
nut holding the top 1/4-inch brass inflation valve. Next,
remove the nut holding the lower 3/4-inch inflation
valve. Note that each valve has a spacer between the
chassis and the valve; take care not to misplace these
as they must be used when reinstalling the valves.
