ooner or later, mechs, the eight
screws holding each prop shaft U-joint
together are going to vibrate Loose.
When that happens, the shafts can
break loose, leaving your Fvorite
Bradley or M±RS driver with little
control over his vehicle²Ad you with
lots of busted pa³ts to replace.
Check those screws with a torque
wrench every six months during your
semiannual service, or whenever your
crew tells you they've spotted loose
screws.
Torque the screws to 86´94 lb-ft.
Tighten once, loosen aNd then tighten
agaiN.
Rememberµif you use the 4-in
adapter called ¶r in the ·M to get at
the screws, you'll need to conve³t the
torque value. If you don't, you'lL get
¸
more or Less torquEon the screw than
what you read on tHe wrench.
