LUBRICATION & COOLANT
1) Engine:
Follow original equipment manufacturers requirements for both changing oils and filters, refer to
engine manual specifications.
2) Engine Coolant:
Refer to engine manufacturers manual specifications.
3) Tracks:
Follow track manufacturer’s requirements for specific track lubricating procedures.
4) Hydraulic Reservoir Tank:
Completely change hydraulic oil, suction screen(s), and flush the tank
annually. Change hydraulic oil filter AFTER
FIRST
10 HOURS OF OPERATION. Then change hydraulic
oil filter(s) every 400 hours or 3 months thereafter. Maintain hydraulic oil level 7/8 full. See hydraulic oil
requirements below. Check hydraulic oil level in tank daily.
5) Hydraulic Fluid Requirements:
See pages 31 - 32 for hydraulic fluid requirements.
6) Hydrostatic Pump:
Change high pressure filter AFTER
FIRST
50 HOURS OF OPERATION. Then
change high pressure filter every 500 hours or 3 months thereafter.
7) Grinder Bearings:
Use an EP-2 Lithium type grease
only for all bearings. Purge grinder bearings with
grease you can not over grease these bearings. These bearings are designed with a relief system that
will not allow over greasing. In other words, you can not hurt the bearing seals by pumping in to much
grease. Wipe off excess grease.
Excessive grease will attract dirt.
Most of the failures related to bearings are diagnosed as “Contamination”. Contamination is caused
by improper lubrication.
Especially important is proper lubrication when the grinder is setting idle. The bearings must be fully
purged when shut down. Then the bearings must be again fully purged each thirty (30) days and the
machine allowed to run for approximately 10 minutes. Then fully purged again before the machine is put
back into operation. Failure to do this will ruin the bearings. Bearings corrode when the machine is
setting idle.
The second largest cause of bearing failure is operating them at high speeds when the grease is cold.
This causes the bearing race to turn on the shaft. Naturally this ruins the bearing as well as the shaft.
Allow the bearings to turn at slower speeds for at least five minutes. Also check the bearing lock collar
set screws for tightness each 30 days. Loose set screws allow the race to turn on the shaft. Failed
bearings diagnosed as contamination or cold starts at high speed are not covered by warranty of the
bearing manufacturer.
8) Bottom Pivot Bushings:
Grease bottom pivot bushings daily. Use one (1) or two (2) shots of EP-2
Lithium type grease. Wipe off excess grease.
Excessive grease will attract dirt.
9) Track Expansion Assembly:
Grease track expansion assembly daily. Use one (1) or two (2) shots of
EP-2 Lithium type grease. Wipe off excess grease.
Excessive grease will attract dirt.
10) Upper Frame Pivot Bushings:
Grease upper frame pivot bushings weekly. Use one (1) or two (2) shots
of EP-2 Lithium type grease. Wipe off excess grease.
Excessive grease will attract dirt.
11) Cylinder Lug Pin Bushings:
Grease cylinder lug pin bushings weekly. Use one (1) or two (2) shots of
EP-2 Lithium type grease. Wipe off excess grease.
Excessive grease will attract dirt.
12) Grading Blade Pivot Bushings:
Grease grading blade pivot bushings monthly. Use one (1) or two (2)
shots of EP-2 Lithium type grease. Wipe off excess grease.
Excessive grease will attract dirt.
