Housing Assembly.
2. Slide on Housing Cover (11), ensuring that Transducer
and Motor wires are not disturbed.
3. Slide Warning Label (12) into Label Cover Lens (13).
Note Warning Label and Label Cover Lens slot and tab
alignment features.
4. Slide Label Cover Lens and Warning Label over Motor
Housing Assembly grip area. Orient tabs of Label Cover
Lens with mating slots in Motor Housing Assembly, and
slide together.
5. Install Retaining Ring (14) into groove behind Label
Cover Lens.
6. Place Spring (16) into Reverse Ring (17).
7. Install and depress Ball (3) and Spring (4) and then slide
Reverse Ring onto Motor Housing Assembly.
When replacing the Motor Housing Assembly (1), always
ensure that the Memory Chip (7), Communication Board (8),
Gear Case Assembly, and Attachment are all assembled as
a set with the new Motor Housing Assembly.
8. Install Memory chip (7) into Housing with terminals
aligned with O-ring groove.
9. Slide two O-rings (15) into groove to retain Memory chip.
10. Install Spring (6) on post in middle of Trigger (5) and
install Trigger into Motor Housing Assembly.
11.
For models with Extended Lever (25),
install an
additional spring on Trigger's auxiliary post.
12. Slide Handle Grip (18, 19, 20, or 21) onto Motor Housing
Assembly.
13. Apply a medium strength thread locker to Low Head
Socket Cap Screw (22).
14. Install Low Head Socket Cap Screw into Motor Housing
Assembly.
15. Torque Socket Cap Screw to 10 to 15 lbf • in (1.1 to
1.7 Nm).
16.
For models with Levers
:
a
Place Lever (24 or 25) in position against Handle Grip
and install lever Socket Cap Screws (23).
b
Torque Socket Cap Screw (23) to 5 to 10 lbf • in (0.5 to
1.1 Nm).
WARNING
•
This procedure is to be performed by an authorized,
trained repair person. To ensure proper functioning
of the tool:
•
In the course of disassembling or assembling this
product, beware of any attempt to separate the gear
case from or tighten the gear case to the motor
housing assembly. Destruction of the transducer
wire will result.
CAUTION
•
When replacing an Attachment, always use the Angle
Head Attachment designed for that model. Never
replace an Angle Head Attachment with an In-Line
Attachment.
•
When replacing a Gear Case Assembly, always use
the Assembly designed for that model.
Gear Case - Assembly
1. Ensure that all the gears are free of debris.
2. Apply 2-3 cc of IR #67 grease to the central area between
the gears and the surface of the gear teeth of the 1st
Stage Spindle Assembly (36) and the 2nd Stage Spindle
Assembly (38).
3. Insert Bearing (42) into threaded end of Gear Case (41)
and push it in until it seats against the shoulder in the
Gear Case.
4. Assembly the Retaining Ring (43) into the groove directly
in front of the Bearing with internal snap ring pliers.
5. Support the Gear Case Assembly, threaded end down,
on the inner race of Bearing (42).
6. Position the 2nd Stage Spindle Assembly (38) on the
inner race of the Bearing (42) inside the Gear Case with
the splined end of the Spindle Assembly facing the
Bearing.
7. With an appropriate tool, press the 2nd Stage Spindle
Assembly into Bearing (42) until the Spindle Assembly
seats against the inner race of the Bearing.
8. Coat the inside and outside surfaces of the Ring
Gear (37) with IR #67 grease.
9. Insert the Ring Gear into the Gear Case with the end of
the Ring Gear having an internal groove towards the
motor.
10. Align the Ring Gear teeth with those of the planets in the
2nd Stage Spindle Assembly and slide the Ring Gear into
the Gear Case until it stops against the shoulder inside
the Gear Case.
11. Install the Retainer (33) into the groove inside the motor
end of the Gear Case to secure the Ring Gear.
12. Insert the 1st Stage Spindle Assembly (36) into the Gear
Case and engage the teeth of the gear on the Gear Head
Assembly with the planet gears of the 2nd Stage Spindle
Assembly while aligning the planet gears of the Gear
Head Assembly with the Ring Gear.
13. Install Retaining Ring (35) into groove in the end of the
Ring gear.
14.
For Non-Flanged Gear Cases:
Slide the Coupling Nut
(40) over the output end of the Gear Case Assembly.
15.
For Flanged Gear Cases:
Slide the Coupling Nut (40) on
the input end of the Gear Case (41). Using the proper
tool, slide the Retaining Ring (39) over the end and into
the groove of the Gear Case.
Gear Case Assembly Installation
1. Install the Pinion Coupler Assembly (34) on the pinion of
the motor.
2. Rotate the Gear Case Assembly to the desired
orientation relative to the Motor Housing Assembly (1).
3. Insert the Motor Housing Assembly (1) into the Gear
Case (41).
4. Align and engage the gear of the Pinion Coupler
Assembly (34) with the Planets of the 1st Stage Gear
Head Assembly (36) while engaging the Ring Gear (37)
with the Transducer (31) teeth. It may be necessary to
rotate the 2nd Stage Spindle Assembly (38) to aid in
assembly.
5. Thread Coupling Nut (40) to the threads of the Motor
Housing Assembly and torque to 50 - 60 f t• lbs
(68 - 81 Nm).
