The PM Scoop
Air Chamber Clamp
Vibration loosens nuts and bolts that hold the brake
actuator air chamber clamp together. When that happens,
air leaks from the chamber. No air means no brakes.
So grab the clamp and see if it’s loose. If it is, get your
mechanic to torque the nuts to 70-80 lb-ft. Between
scheduled 250-hr services, look for loose nuts, shiny
spots or rust around the bolt heads and nuts on both the
front and rear air brake chambers. If you spot any, report
them to your mechanic.
•
Use two wrenches to
keep from twisting the
hose when loosening the
connection on the upper
hose for each forward
lift cylinder. It takes a
1 1⁄4-in and a 1 3/16-in
open-end wrench to
loosen the connection.
•
Get a buddy to hold the hose about an inch from the steel line while you tighten
the connections.
•
If a hose is worn through its outer cover, replace it.
•
Paint any bare spots on the steel lines.
