The planetary gear group is being held onto the sprocket housing at this time only by Tooling (H). The approximate weight of the planetary group is 163 kg (360 lb). Be careful not to allow the planetary gear group to slide outward.
Remove bolts (3) and ring gear (4) from cover assembly (2). Apply Tooling (K) onto cover assembly (2). Install the cover assembly (2) onto the final drive. Install bolts (1), and tighten to hold oil in the final drive. Fill final drive with oil. Refer to Operation and Maintenance Manual, "Final Drive - Oil Change".

At operating temperature, the hydraulic oil is hot and under pressure. Hot oils can cause burns.To prevent possible personal injury, release the pressure in the work tool hydraulic circuit (boom, stick, bucket, and swing), travel circuits, and the hydraulic oil tank at the filler cap before any hydraulic lines or components are disconnected or removed.Remove the filler cap only when the engine is stopped and the filler cap is cool enough to touch.

Illustration 13 g06314884Note: Use the identifying marks on the upper structure, on the swing gear, and on the undercarriage to align the undercarriage with the upper structure for assembly purposes.Note: Loosen bolts (16) that will be over tracks before swinging upper frame to 90 degree position for removal.
Remove tube assembly (15). Remove two bolts (16) from swing gear. Install Tooling (F) into swing gear to maintain alignment for assembly . Remove remaining bolts (16). Use Tooling (D), Tooling (G), and Tooling (E) to raise the upper structure off the undercarriage in increments of 13 mm (0.5 inch). Raise the upper structure until the upper structure is
