Clutch Greasing Guidelines | General Information TRSM0930

Clutch Greasing Guidelines

Caution: It is highly important to follow proper clutch lube

intervals as specified in Lubrication Manual TCMT0021. Failure to do so may result in clutch failure and unnecessary repairs.

The heavy-duty ECA clutch housing has 2 grease fittings on the lower right side. The upper port is marked “CS” for the upper cross-shaft assembly, while the lower port is marked “RB” for the release bearing.

For more detailed cross-shaft greasing information refer to the Release Yoke and Cross-shaft Installation section of this manual. Refer to Clutch Service Manual CLSM0200, for release bearing greasing information.

ServiceRanger Procedure

Grease Interval Count Reset

The Heavy-Duty UltraShift PLUS has an optional prognostic feature that notifies the operator when the Clutch Release Bearing needs greasing. This feature can be enabled or dis abled via ServiceRanger.

At the appropriate grease interval and shortly after each engine start, “GI” will momentarily appear in the gear dis play, along with an audible tone. This will continue to occur at each engine start until clutch service has been com pleted.

Note: “GI” stands for grease interval and may be misread as “G1”on gear display.

The operator can choose to follow this automated lube schedule or the published lube guidelines in the Lubrication Manual TCMT0021. When enabled, it is highly important to reset the grease interval count every time the Release Bear ing is greased.

The grease interval count can be reset via ServiceRanger or Operator-Triggered Special Function.

Thread-In ECA Speed Sensor | Service Procedure TRSM0930

Procedure - Installation

1. Thread Speed Sensor into the Engine Bell Housing until

it touches the flywheel.

2. After the sensor touches the flywheel, rotate it counter-

clockwise 1/2 to 1 full turn.

3. Hold the sensor in place and tighten the 3/4”-16 jam

nut to 15 lb-ft. (20.3 Nm).

4. Apply included material to low-voltage 4-way harness

connector terminals.

Note: Apply just enough material to cover the end of

the terminal.

Note: Use only Eaton lubricant part number 5564527.

(Nye Lubricants NYOGEL 760G. For MSDS safety or other information see www.nyelubri

cants.com).

5. Connect Engine Speed Sensor Connector to the mating

connector on the transmission and fasten harness, if needed.

TRSM0930 Service Procedure | Electronic Clutch Actuator (ECA)

Procedure - Removal

Warning: Ensure the Hand Hole Cover is closed when

removing the ECA.

1. Disconnect the negative battery cable.

2. Disconnect the 8-way and 3-way connectors from the

ECA.

Note: Some models do not use a shield.

3. Remove the 4 cap screws from the ECA shield and

remove shield.

Note: Medium-duty models are mounted with 3 cap

screws and 1 lock nut.

4. Remove the 4 cap screws from the ECA mounting

flange.

5. Remove the ECA.

Note: The ECA has an alignment pin that requires the

unit to be rotated to exit the clutch housing bore.

Note: If ECA will not slide from the clutch housing after

all the fasteners are removed, use the available pusher holes found on both sides of the ECA casting. Place the included jackscrews into the holes. Turn each jackscrew until it touches. Next, turn the upper jackscrew 1 turn; then rotate to the lower jackscrew and rotate it 1 turn. Continue until the ECA is fully displaced from the bore.
