Komatsu — 10 HOUR (SHIFT) Lubrication and Maintenance Checks

Maintenance - Section 4 08/07 OM4016 Page 4-6 Lubrication and Service 10 HOUR (DAILY) INSPECTION (continued) WHEELS a. Check to see that all wheel lugs/wedges are in place and tight. b. Inspect rear wheels for any leakage that may be coming from inside the wheel housing that would indicate planetary leakage. c. Check rear dual wheels for any rocks that might be lodged between dual tires. d. Check that rock ejector is in good condition and straight, so that it can not damage a tire. After each wheel mounting operation, recheck wheel mounting capscrew tightness after 4 - 5 hours of operation.

Check again at the end of the shift, and then periodically until all capscrews hold at the prescribed 225 ± 25 kg.m (1628 ± 180 ft.lbs.) torque (dry threads). This is prescribed for both front and rear wheels. Tighten wheel nuts in the order as shown in the diagrams. COMMENTS CHECKED INITIALS
