Safety Information

Using Set Screws

WARNING: Auxiliary driveshafts may be installed with either
recessed or protruding set screws. If you choose a square head
set screw, you should be aware that it will protrude above the hub
of the yoke and may be a point where clothes, skin, hair, hands,
etc. could be snagged. A socket head set screw, which may not
protrude above the hub of the yoke, does not permit the same
amount of torquing as does a square head set screw. Also a
square head set screw, if used with a lock wire, will prevent
loosening of the screw caused by vibration. Regardless of the
choice made with respect to a set screw, an exposed rotating
auxiliary driveshaft must be guarded.

Pump Installation Precalculations

Use a bracket to support the pump to the transmission if:
■ The pump weighs 40 pounds or more.
■ The combined length of the P.T.O. and pump is 18 inches or
more from the P.T.O. centerline to the end of the pump.
Increased torsional vibrations found in high torque low R.P.M.
engines can lead to premature wear of the mating shafts and is
accelerated if the shafts are not lubricated. Each Chelsea P.T.O.
that features a female pump shaft will include a packet of lubricant.
Apply this to the male end of the pump shaft before installing the
pump to the P.T.O.
This symbol warns of possible personal injury.
