GASKET-CYLINDER HEAD 2822470 - Caterpillar

SMCS Code: 6501-086; 6502-086 For some applications of the machine, the repeated duty cycle of the front linkage may only require small angular movements of the boom or stick. There might not be enough angular motion in order to distribute the grease between the pin and the bearing. The operator should operate the boom, the stick and the implement in order to distribute the grease within the joint assemblies.
Illustration 24Service a new machine after Every 10 Service Hours only within the initial 100 service hours.After the initial 100 service hours of operation, service the boom, the stick, and the implement linkage after Every 50 Service Hours. If the machine is operated under severe conditions that might cause abrasive material to enter the cylinder bearings, service the boom and the stick after Every 10 Service Hours.Wipe all fittings before you apply lubricant.
Illustration 251. Apply lubricant through the fitting at the base of each boom cylinder.
Illustration 262. The fittings are at the base of the boom. To lubricate the lower boom bearings, apply lubricant through fittings (1) and (2). To lubricate the boom cylinder rod, apply lubricant through fittings (3) and (4). To lubricate the stick cylinder head, apply lubricant through fittings (5) and (6). To ensure proper lubrication of the lower boom bearings and of the boom cylinder rod end bearings, lubricant should be applied through fittings (1), (2), (3), and (4). Apply lubricant first when the boom is raised and any implement is suspended. Then apply lubricant when the boom is lowered and the implement is rested on the ground with a slight downward pressure.
Illustration 273. The fittings are located at the end of the stick. Apply lubricant through fittings (7) and (8) in order to lubricate the connection point of the boom and the stick.Apply lubricant through fittings (9) and (10) in order to lubricate the rod end of the stick cylinder.
