Important
Rotating shafts can be dangerous. Clothes, skin, hair, hands, etc. can become snagged or
tangled, causing serious injury or death.
Do not work on a driveshaft or pump when the engine is running or without the wheels
chocked.
Great care must be taken in the layout of pump drivelines. Interference and driveline vibration
must be considered. An experienced installer with knowledge of driveline considerations,
proper layout and recommended guidelines should be utilized as well as proper CAD systems
for driveline layouts. Installation of the driveline should not occur until a proper analysis is
performed by either a qualified driveline specialist or W.S. Darley. W.S. Darley utilizes, can
distribute and can train qualified individuals to use the Allison Multiple Joint Driveline Analysis
program.
W.S. Darley requires that Power Take Off (PTO) driven pumps have at most 500 radians per
second
2
torsional vibration and at most 1000 radians per second
2
inertial drive torsional
vibration, as calculated by the Allison Multiple Joint Driveline Analysis program, for a
completed driveline installation. A completed driveline installation includes the entire multi-
driveshaft assembly from the power source of the PTO output flange to the input flange of the
PTO driven pump.
Failure to design and analyze a proper driveline layout could result in severe injury and damage
to equipment, including but not limited to: the water pump, the water pump transmission, drive
tubes, hanger bearings, u-joint crosses, gears, the rear differential, and the main truck
transmission.
Exposed rotating drive-shafts should be guarded.
It is highly recommended by Darley to use safety rings around drive tubes. Especially near
connecting u-joint crosses. Such safety rings would be sufficiently attached to the chassis
frame and sufficiently strong enough to prevent a broken u-joint assembly from allowing a
driveline to slide out from underneath the truck at high speeds while still rotating, causing
severe personnel injury. Said safety rings would be larger than the drive tube OD and provide
enough clearance for dynamic non-rotational movement of the drivelines through loaded and
unloaded conditions, driving operations and where chassis flex may occur.
