BEARING-SLEEVE 2810905 - Caterpillar

The operator presence sensor is a passive membrane sensor. The sensor alerts the chassis ECM if an operator is in the seat.Seatbelt Beacon Relay
Illustration 4 g03323937The seatbelt beacon relay controls the operation of the seat belt beacon. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the seatbelt beacon.Horn Relay
Illustration 5 g03323937The horn relay controls the operation of the horn. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the horn.Floodlamps Switch
Illustration 6 g03583708The floodlamp switch controls the operation of the flood lights. There is an ECM contact associated with the switch, allowing the ECM to determine if the flood lights are turned on.Heated Glass Switch
Illustration 7 g03583771The heated glass switch controls the operation of the window heaters. The switch has an ECM contact that the ECM monitors to determine the operator request for heated glass.Heated Mirror Switch
Illustration 8 g03583771The heated mirror switch controls the operation of the mirror heaters. The switch has an ECM contact the ECM monitors to determine the operator request for heated mirrors.Seatbelt Switch
Illustration 9 g03350093The seatbelt switch is a single pole switch. The switch has a normally connected and a normally open contact. When the switch is not engaged the normally connected contact is connected to the return, and the normally open contact floats to a high voltage state. When the switch is engaged, the normally open contact is connected to the return and the normally connected contact floats to a high voltage state. Based on the voltage state of the two ECM contacts, the ECM determines if the switch is engaged. The switch alerts the ECM of the state of the seatbelt.Heated Glass Relay
Illustration 10 g03323937The heated glass relay controls the operation of the window heaters. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the heaters.Front Heated Window Relay
Illustration 11 g03323937The heated glass relay controls the operation of the front window heater. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the heater.Heated Mirror Relay
Illustration 12 g03323937The heated glass relay controls the operation of the mirror heaters. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the heaters.Fuel Level Sensor
Illustration 13 g03583114The fuel level sensor is an active analog sensor. The sensor has a tube which is filled with fuel at the same height as the tank. The output voltage of the sensor is proportional to the level of fuel in the tube.Backup Alarm Relay
Illustration 14 g03323937The backup alarm relay is controlled by the Chassis ECM and allows power to flow to the backup alarm when the relay is activated.
