Placement examples are shown in the PTO Owner s Manual IN84 03. 34 After installation of the hydraulic system and filling the reservoir with the. proper hydraulic fluid operate the system and listen for noise It is a common. occurrence that this PTO system will produce a rattling noise Most of this. noise can be attributed to the total drivetrain torsional vibration which is. transmitted through the components and amplified by the heat shield system. installed around and to the PTO When the hydraulic system is energized and. placed under a load this noise should greatly diminish If this is the case then. the noise should not be detrimental to the application If not then double. check that you have used the proper mounting gasket 13M13541 030 to. mount the PTO Then remove PTO for inspection of transmission and PTO. 35 To operate the PTO be sure that the engine is at idle speed Turn the rotary. switch to the On position, 36 Enclosed are operating instructions for the switch and throttle advance. 37 The vehicle is supplied from the Dealer with the preset throttle option If. you desire the variable throttle option the vehicle control module will need. to be changed by the Dealer,PTO OPERATION, Recommended procedure for engaging a PTO Auto Transmission. 1 For stationary use Shift transmission into Park P. 2 Rotate PTO control switch to the on position The. PTO will engage while vehicle is stationary or,mobile if the engage criterion is met.
3 If the engine speed is below the PTO engage, speed limit the PTO will start The blinking LED on. the PTO control switch indicates PTO engage is,requested When the PTO engages the LED on the. PTO control switch changes from blinking to steady state. Using PTO speed control in Preset Mode Factory Default Setting. 1 PTO engaged, 2 Select PARK P or NEUTRAL N Range Recommend applying Park Brake. if Neutral is selected Torque Converter Clutch TCC lockup is not available. in Neutral TCC lockup is available in Park if above 1100 rpm. 3 Foot off brake pedal and off clutch for manual transmission. 4 Select desired engine speed for PTO operation Please read the following. Preset Mode section regarding operation,Preset Mode. PTO speed control mode used for stationary applications. PTO will remain engaged while mobile in the preset mode. however PTO set and resume speed controls will be inop. erative This mode provides a default standby speed of. 800 or 850 rpm depending on the engine transmission. combination and two default PTO control speeds PTO. Set Speed of 1250 rpm and PTO Resume Speed of 1700. rpm Please note that the standby speed 800 850 rpm is. not to be used as a PTO control speed Vehicles not equipped with cruise control. will not have the resume speed capability The graphics on page 15 depict how to. achieve the desired speeds with the set and resume switches. w o Cruise,Variable Mode, PTO speed control mode used for both stationary and.
mobile applications This mode allows PTO to be con. trolled in a fashion similar to which a cruise control con. trols vehicle speed The operator can set to a RPM,between 800 and 2200 with the set switch on the. cruise stalk or with the set position on the PTO,rotary switch The operator is then able to tap up. in 100 rpm increments with the resume switch on,the cruise stalk or tap down with either set. switch on the cruise stalk or the PTO rotary,switch Vehicles not equipped with cruise control. will not have the tap up capability, Using PTO speed control in Variable Mode while Mobile.
1 PTO engaged,2 Vehicle speed greater than 5 mph, 3 Foot off brake pedal and off clutch for manual transmission. 4 Obtain desired engine speed with foot pedal and select set on the PTO. rotary switch or the cruise stock, Using PTO speed control in Variable Mode while Stationary. 1 PTO engaged,2 Vehicle speed less than 5 mph, 3 Foot off brake pedal and off clutch for manual transmission. 4 Obtain desired engine speed with foot pedal and select set on the PTO. rotary switch or the cruise stock, Note All engine speed values listed above are factory default values With the exception of the TCC. lockup speed 1100 rpm and the tap increment 100 rpm all of these values are programmable and. can be adjusted by your GM dealer or body upfitter with a Tech 2 service tool If your vehicle PTO soft. ware settings do not match the settings shown here then they may have already been altered by the.
