BEARING-SLEEVE 1140752 - Caterpillar

System Operation Description:Use this procedure under the following situation:The vehicle wiring and the ECM are suspected of not functioning properly for the features of dedicated PTO.The following background information is related to this procedure:INPUT 1INPUT 1 is used for the circuit for the PTO On/Off Switch when the PTO configuration is programmed to Cab Switches, Remote Switches or Remote Throttle.When the PTO On/Off circuit is on, the ECM will be in dedicated PTO mode.When the ECM is in the dedicated PTO mode the engine retarder is disabled and the PTO Top Engine Limit (TEL) and the torque limit are activated. The engine may proceed directly to the PTO Engine rpm Set Speed if the parameter is programmed. If a PTO Switch ON Lamp is connected to the OUTPUT 1, the PTO Switch ON Lamp will turn on whenever the PTO On/Off circuit is on. If the problem is with undetermined PTO kickouts, use the following procedure:Operate the vehicle in PTO mode.After the kickout, review the status on the Caterpillar Electronic Technician (Cat ET). The status on Cat ET indicates the cause. This must be performed before the ignition key switch is turned off. It is important to remember that the status will only indicate the last kickout since the ECM has been powered by the ignition key switch.This status is blank when the ECM is first powered up. If this status is blank, "No Occurrence" is indicated. This status remains blank until the ECM detects the use of the PTO mode. Also, this status remains blank until the ECM detects the disengagement of PTO mode. Refer to table 1 in order to interpret the status screen.The status is available for the following kickouts:
PTO KickoutPTO Interlocks may also be connected in series with the PTO On/Off switch. The Interlocks are intended to prevent the PTO On/Off circuit from activating unless certain conditions are met.INPUT 2The INPUT 2 is used for the PTO SET/ACCEL Switch when the PTO configuration is programmed to Remote Switches or Remote Throttle.INPUT 3The INPUT 3 is used for the PTO RESUME/DECEL Switch when the PTO configuration is programmed to Remote Switches or Remote Throttle. The PTO Configuration Is Set To Cab Switches.When the PTO configuration is programmed to Cab Switches and the PTO On/Off switch is on, the following circuits can be used to interrupt a set rpm:
Cruise Control Set/Resume Switch
Service Brake Pedal Position Switch 1
Service Brake Pedal Position Switch 2
Clutch Pedal Position Switch
Neutral SwitchThe engine speed can be limited if the "PTO Configuration" is programmed to "Cab Switches" and the PTO On/Off switch is in the On position. The engine speed can be limited by setting the "PTO Cab Throttle RPM Limit" parameter:
Low Idle
PTO Top Engine Limit
Top Engine LimitThe "PTO Configuration" is set to Remote Switches or Remote Throttle.When the "PTO Configuration" is programmed to Remote Switches or Remote Throttle and the PTO On/Off switch is on, the following circuits are ignored:
Service Brake Pedal Position Switch 1
Service Brake Pedal Position Switch 2
Clutch Pedal Position
