Maintenance 4-1 HP6A Manual
Chapter 4 Maintenance:
Lubrication:
Refer to the Material Safety Data Sheets in Section 8 for information on proper use
and handling of lubricants mentioned in this maintenance section.
Refer to illustrations on page 4.3 and a list of manufacturers and oil types on page 4.4.
Grease Fittings
There are two grease fittings located on the rocker arm pivot bearings. On the block hold down fixture
there are two grease fittings. Each optional clamp arm assembly has one grease fitting.
Every 175 hours,
these grease fittings should be greased, using Unoba EP 2 Multi-purpose
grease, or equivalent NLGI-2 grease.
Gear Housing
The gear housing is located at the front end of the rocker arm. The gear housing is what drives and
adjusts the hone head.
Every 1,000 hours, check the oil level in the gear housing. The arm must be in the horizontal position.
Remove the plug on the upper left side of the gear housing. The oil level should be up to this hole. If oil
is needed, add to this hole. Use any 20-weight (ISO VG-) non-detergent motor oil.
NOTE: DO NOT OVER FILL! If over-filled, oil will spill out of breather cap. To drain oil remove a screw
from the stop sensor bracket.
U
niversal Joint
The universal joint connects the hone head adjusting shaft assembly to the gear housing.
Every 8 hours,
Lubricate the hinge points of the universal joint with 30 weight (ISO VG-) machine oil.
Automatic Lubricator
The oil injection lubricator is located on the back of the main base. The oil injector lubricates the stroking
cylinder. The automatic injection lubricator is controlled by the program. The controller will activate the
injection lubricator at a predetermined time interval. The time interval can be changed in the controller.
See Machine Parameters.
When needed, add hydraulic oil to the reservoir. Use Mobil DTE 24 hydraulic oil, or any equivalent,
highly refined, turbine, or hydraulic S.A.E #10 (ISO VG-46) or lighter petroleum oil (non -detergent)
with medium aniline point (ASTM oil #2). Rottler sells lubricator oil by the quart, part # 514-3-93A
NOTE: Only use oil that is compatible with Nitril seals, and will not cause them to swell.
DO NOT use compounded oils containing graphite, silicones, soaps or fillers. Hydraulic fluids containing
phosphate esters (skydrol, fyrouel, pydraul, etc.) or fire resistant oils containing phosphate esters.
