SECTION 3 - CHASSIS & TURNTABLE
3-40 3121714
Preparation Before Disassembly
• Before you disassemble the motor unit or any of its compo-
nents read this entire section. It provides important infor-
mation on parts and procedures you will need to know to
service the motor.
• Thoroughly clean off all outside dirt, especially from
around fittings and hose connections, before disconnect-
ing and removing the motor. Remove rust or corrosion
from coupling shaft.
• Remove coupling shaft connections and hose fittings and
immediately plug port holes and fluid lines.
• Remove the motor from system, drain it of fluid and take it
to a clean work surface.
• Clean and dry the motor before you start to disassemble
the unit.
• As you disassemble the motor clean all parts, except seals,
in clean petroleum-based solvent, and blow them dry.
PETROLEUM-BASE SOLVENTS ARE FLAMMABLE. BE EXTREMELY CAREFUL
WHEN USING ANY SOLVENT. EVEN A SMALL EXPLOSION OR FIRE COULD CAUSE
INJURY OR DEATH.
WEAR EYE PROTECTION AND BE SURE TO COMPLY WITH OSHA OR OTHER MAX-
IMUM AIR PRESSURE REQUIREMENTS.
NEVER STEAM OR HIGH PRESSURE WASH HYDRAULIC COMPONENTS. DO NOT
FORCE OR ABUSE CLOSELY FITTED PARTS.
• Keep parts separate to avoid nicks and burrs.
• Discard all seals and seal rings as they are removed from
the motor. Replace all seals, seal rings and any damaged or
worn parts with OEM approved service parts.
Disassembly and Inspection
1. Place the motor in a soft jawed vice, with coupling shaft
(12) pointed down and the vise jaws clamping firmly on
the sides of the housing (18) mounting flange or port
bosses. Remove manifold port O-Rings if applicable.
IF THE MOTOR IS NOT FIRMLY HELD IN THE VISE, IT COULD BE DISLODGED
DURING THE SERVICE PROCEDURES, CAUSING INJURY.
2. Scribe an alignment mark down and across the motor
components from end cover (2) to housing (18) to facili-
tate reassembly orientation where required.
