4. MAINTENANCE 3. Tires and Wheel Nuts Inspect tires for wear or damage. Check and inflate tires to correct pressure: 12.00 x 16.5 ...........40 - 45 PSI (276 - 310 kPa) Tires can be inflated to 50 PSI (345 kPa) when operating on hard, flat surfaces. Torque Wheel Nuts 100 - 110 lbs. ft. (136 - 149 Nm) To prevent shearing of the wheel studs and rim damage check wheel nuts for proper torque 100 -110 lbs. ft. (136 - 149 Nm) daily (Fig. 4.3C). After changing a rim, Check wheel nuts hourly, until the reading stabilizes. 4. Track System Inspect track system. Remove debris and any items imbedded in the track. Check sprocket hub nut torque (100-110 lbs.ft. (136-149 Nm).
Inspect Scrapers (See Fig.4.3D). Fig. 4.3C 5. Safety Equipment Check all safety equipment for proper operation and condition - seat belt, lift arm supports, seat bar, parking brake, quick tach lock, shields, safety treads and control locks. Lubricate all linkages, springs and pivot points with a silicone based lubricant. Repair or replace if necessary. Torque Nuts 6. Decals Check the condition of all safety and instruction decals. Replace any damaged or missing decals. Refer to Section 5.3 for decal description and locations. Fig. 4.3D C4467 7. Lubrication (Wheel Loader) There are sixteen (16) grease fittings located on the wheel loader that require lubrication every eight hours.
Lubricate with a good quality multi-purpose lithium based grease. Apply grease until excess shows. Refer to the service schedule for complete service details. (See Fig. 4.3E). The sixteen (16) lubrication points are: Rear Lift Arm Pivots (2) Lift Cylinder Bushings (4) Bucket Cylinder Bushings (4) Lift Arm Supports (2) Quick Tach Pivot and Lock Pins (4) C4394 Fig. 4.3E 41
