Maintenance _____________________________________________________ Weekly crawler track take-up bearings
Lubricate the right and left hand crawler track take-up bearings (Fig. 33). The fittings (one per side) may be reached through the slot in the end of the crawler frame on the outside of each crawler. Pump grease into the fitting until new grease can be observed coming out of the bearings. Fig. 33: Crawler track take-up lubrication

Check the conveyor chain tension. With the machine running, visually inspect tail shaft to ensure shaft is turning and conveyor shaft is not sliding across tail shaft. If adjustment is necessary, see Conveyor chain adjustment procedure in this chapter. Due to the machine being subjected continual shock loading and vibration, close attention to all mounting bolts and screws is required. Loose fasteners will cause premature wear and failure to bearings, couplings, etc. Inspect and tighten as required the following fasteners: ■
head shaft bearing bolts
■
breaker shaft side plate bolts
■
conveyor drive motor mounting bolts
■
tail shaft retainer hold down bolts
■
all cover and guard retaining bolts
Visually inspect all electrical cables and glands for signs of wear or damage. Visually inspect all hydraulic hoses and fittings for signs of wear, damage or leakage. This inspection should be performed with machine running.
