Manual Extract: Track Roller Lower Roller – Filling Procedure

Before proceeding, ensure the completion of the track roller lower roller leakage test (48.138).

1. Position the shaft so the end cap’s mounting surface faces downward, and the filler opening is upward.
2. Fill the roller with the recommended lubricant, as specified in the Capacities section.
3. Attach an air line that can be controlled to a maximum pressure of 275 kPa, 2.7 bar (40 psi) to the filler opening.
4. Open the air line valve to distribute the lubricant evenly to the outer ends of the roller.
5. Close the valve and safely disconnect the air line.
6. Verify the oil fill volume by aligning the roller with the oil fill hole at its top.
7. Use a dipstick to measure the oil level; it should indicate 5.0 to 8.0 mm (0.195 to 0.315 in) above the top of the shaft.
8. Securely install and tighten the plug to complete the process.
