2.3 RECOMMENDED LUBRICANT SPECIFICATIONS
2.3.1 Hydraulic Fluid
McCoy Global recommends using high-quality hydraulic fluid containing rust & oxidation inhibitors and foam
suppressant that meets the following requirements. Operating this equipment using hydraulic fluid that does not
meet these requirements greatly accelerates equipment damage due to (but not limited to) premature component
wear, premature seal failure, cavitation, and fluid starvation.
!
CAUTION
OPERATING THIS EQUIPMENT USING HYDRAULIC FLUID THAT DOES NOT MEET THE LISTED
REQUIREMENTS GREATLY ACCELERATES EQUIPMENT DAMAGE.
Hydraulic Fluid Standards
Characteristic Requirement
Maximum viscosity at cold startup <1000 cSt (<4600 SUS)
Operating viscosity range 100 to 16 cSt (170 to 80 SUS)
Minimum viscosity (intermittent periods only) 10 cSt (60 SUS)
Hydraulic uid operating temperature range 86 - 140°F (30 - 60°C) - measured in main reservoir
Maximum uid temperature 180°F (82°C)
Fluid cleanliness Filtered to ISO 4406:1999 (22/18/13)
Hydraulic fluid should be chosen with due regard to expected climactic conditions and equipment load. Note that
this equipment may have been tested using hydraulic fluid that does not meet operational requirements beyond
those specified in the above table. Therefore, McCoy recommends purging and flushing the equipment’s hydraulic
system before connecting to a hydraulic supply.
NOTICE
MCCOY GLOBAL RECOMMENDS PURGING AND FLUSHING THE EQUIPMENT’S HYDRAULIC SYSTEM
BEFORE CONNECTING TO A HYDRAULIC SUPPLY.
2.3.2 Gear Fluid
McCoy Global recommends using a high-quality universal gear uid in gearbox and torque hub assemblies. If
required, the gear uid should meet VG150/VG220 or AGMA 4EP/5EP speci cations. However, in more extreme
operating conditions it may be necessary to ll the gearboxes on the equipment with gear uid more suitable to
the ambient operating environment. Refer to the following table to determine McCoy Global’s recommendations
for gear uid selection.
Gear Fluid Standards
Operating Condition Requirement
-4°F to 41°F (-20°C to 5°C) meets ISO VG100 or AGMA 3EP speci cations
41°F to 104°F (5°C to 40°C) meets VG150/VG220 or AGMA 4EP/5EP speci cations
greater than 104°F (40°C) meets VG320 or AGMA 6EP speci cations
2.3.3 Grease
McCoy Global recommends use of a high-quality EP multi-purpose grease with an NLGI consistency grade of "2"
and an NLGI performance grade of "GC-LB" for general lubrication of bearings and metal-to-metal contact.
McCoy Global recommends thoroughly greasing the equipment before first use as per the lubrication instructions
in Section 5.
