NOTE:
Milk white grease indicates that the grease has been contaminated. Consult your SANY dealer in order
to change the grease.
6. Reinstall cover (b).
Top Roller Bolts - Check
1. Inspect mounting bolts (a) that secure the support roller
to the side frame for rust, damage or looseness.
2. Replace any damaged or defective bolts and tighten any
loose bolts.
NOTE:
Use anaerobic sealant when tightening loose
bolts and installing new bolts.
Track Assemblies - Check
NOTE:
Step 2 applies to metal track only.
NOTE:
Use a pry bar to shift and/or lift the track shoes as needed to perform this procedure.
1. Remove as much accumulated dirt as possible from the track assemblies. Excess dirt requires more energy to
operate the crawlers and causes severe wear of moving parts of the track.
2. Check track pads (a) for damage, wear, unevenness, looseness, raised sections, and tightening of crawler pads
or any other abnormality.
3. Check idler (b) track roller (c) and supporting rollers (d) for wear, leaks, lubrication and proper operation.
4. Check crawler final drive motors (e) for wear and lubrication of the gearbox.
