PTO & Pump Installation
In some cases the customer or his agent may have to install a compressor, PTO, and pump.
These instructions will provide general information to assist with installation. The pump may be
installed either directly on the PTO or may be driven by a driveline.
PTO Installation
A power take-off (PTO) must be properly matched to the vehicle’s transmission as well as the
requirements of the crane. In order to properly select a PTO the following information is needed:
1
Make and model of transmission in the carrier vehicle.
2
Power requirements of the crane being driven.
3
Necessary PTO speed.
4
Direction in which the PTO must turn.
5
PTO torque required.
If possible, use a hydraulic pump directly mounted to the PTO. This will eliminate an auxiliary
driveshaft and it is easier to install as it eliminates driveline angle and phasing errors. It is also
quieter and should require less maintenance since driveline lubrication will not be necessary.
PTO manufacturers provide specific installation instructions with their products. Their
instructions should be followed when installing the PTO. The following steps are provided as an
introduction to the installation.
NOTE
IT MAY BE NECESSARY TO REMOVE AND MODIFY EXHAUST COMPONENTS TO
PROVIDE SPACE FOR PTO CLEARANCE.
1
Chock the wheels of the vehicle.
2
Secure any part attached to or on the vehicle which could move or pose a hazard.
