70 SERIES DRIVE HEAD ASSEMBLY
NO. 25200
LUBRICATION - DRIVE HEAD
Location:
Filler spout is located on the inspection plate assembly on
opposite side from pinion shaft (119).
Oil:
ISO grade 150 hydraulic oil with rust and oxidation inhibitors
and anti-wear additives. Viscosity to be 150-220 cSt @ 40 °C. The
base oil viscosity at the bearing operation temperature must be
a minimum of 40 cSt.
Quantity:
Four gallons (15.2 liters) – Drain oil by removing plug (82) from
the housing assembly (77) and two plugs (87) in the pump
sump assembly (84). Remove breather vent (127) to equalize
pressure when draining.
Check oil flow at sight tube (92) located on inspection plate
assembly (94). Oil flow will be a small stream and begin
approximately one minute after startup.
Oil Change Interval:
Every 4000 operating hours
LUBRICATION - CRANKPIN BEARING
Location:
Grease at single fitting located on top of crankpin.
Grease:
Extreme pressure (EP) multipurpose type with NLGI No.2 rating
and base oil viscosity of 160-240 cSt @40°C (nominal 875 SUS
@100°F). The minimum viscosity index of the base oil must be 95.
CAUTION: DO NOT USE GREASE CONTAINING MOLYBDENUM
DISULFIDE ADDITIVES BECAUSE BEARING WILL BE DAMAGED.
NOTE: FOR BEARING OPERATING TEMPERATURES MORE THAN
140°F (60°C) THE BASE OIL VISCOSITY MUST NOT BE LESS
THAN 40 CST AT THE BEARING OPERATING TEMPERATURE.
Quantity:
25 grams or approximately 25 pumps from a standard
lever-type grease gun
Interval:
Every 750 operating hours
NOTE: THE LUBRICANTS AND SERVICE INTERVALS SPECIFIED
ARE FOR NORMAL OPERATION IN AREAS BETWEEN 40°F
AND 140°F (4°C-60°C). CONSULT ROTEX IF BEARING
TEMPERATURES ARE MORE THAN 140°F (60°C) OR THE
MACHINE IS OPERATED UNDER SEVERE CONDITIONS.
