192 OPERATION
PTO Classification
Rear-mounted PTO units, for MACK transmissions, are categorized according
to operation.
Intermittent Service —
The PTO unit is operated, under load, for less than
seven minutes and then allowed to cool before it is operated again.
Note:
If a PTO unit is operated for less than seven minutes but is "not" allowed to
cool down before operating again, it is considered in Continuous Service.
Continuous Service —
The PTO unit is operated, under load, for seven
minutes or more.
Note:
Rear-mounted PTO units operating under the Continuous Service guideline
must not be run at more than 70% of the PTO output-rated torque/horsepower.
Side-Mounted PTO Locations
The first choice location for Side-Mounted PTOs is either of the PTO openings
on the main box.
The second choice, which is the compound PTO opening, is restricted to
those applications specifically requiring multi-speed PTOs with reverse
capability, such as some mechanical winches or unique speed or multiple
PTO requirements. However, a word of caution is in order when using these
locations. Operators should be trained to understand and follow the proper
operating procedures as described in the cab instructions, and avoid using the
neutralizing feature as a power disconnect for vehicle propulsion.
PTO Operating Procedures
Specific PTO operating procedures are described at the end of applicable
transmissions in the following section.
