MAINTENANCE SECTION
Always wear eye protection when operating or
performing maintenance on this tool.
Always turn off air supply and disconnect air supply
hose before installing, removing or adjusting any
accessory on this tool, or before performing any
maintenance on this tool.
LUBRICATION
Each time the Series 6W Angle Wrenches are
disassembled for maintenance, repair or replacement of
parts, lubricate the tool as follows:
1. Work approximately 1.5 cc of Ingersoll–Rand No. 67
Grease into the Rear Rotor Bearing (35), Front Rotor
Bearing (42), and the Spindle Bearing (61).
2. Work 6 cc to 8 cc of Ingersoll–Rand No. 67 Grease
into the L ratio gear train and 10 cc to 12 cc of the
grease into the gear train of all other ratios. Grease
the Planet Gear Bearings (47, 52, and 54), the gear
teeth inside the Gear Case (56) and the planet gear
shafts on the Spindle (43) and the Gear Head (50).
3. Work 0.5 cc to 1.0 cc of Ingersoll–Rand No. 67
Grease into the Lower Spindle Bearing (113).
4 Work 0.5 cc to 1.0 cc of Ingersoll–Rand No. 67
Grease into the Upper Spindle Bearing (104), Bevel
Pinion Bearing (106), and Bevel Pinion Thrust
Bearing (112). Apply 2 cc to 3 cc of the Grease to
the Matched Bevel Gear Set used in 6L2D6 Angle
Attachments.
DISASSEMBLY
General Instructions
1. Do not disassemble the tool any further than
necessary to replace or repair damaged parts.
2. Whenever grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws to
protect the surface of the part and help prevent
distortion. This is particularly true of threaded
members and housings.
3. Do not remove any part which is a press fit in or on a
subassembly unless the removal of that part is
necessary for repairs or replacement.
4. Do not disassemble the tool unless you have a
complete set of new gaskets and O–rings for
replacement.
Disassembly of the Angle Attachment
1. Carefully clamp the flats of the Coupling Nut (122) in
leather–covered or copper–covered vise jaws, with the
Angle Housing Assembly (101) facing downward.
The Gear Case (56) has left–hand threads.
2. Using a wrench on the flats of the Gear Case, loosen
the Gear Case from the Coupling Nut. Remove the
tool from the vise. Unscrew and remove the Coupling
Nut from the Gear Case.
3. Carefully grasp the Angle Housing Assembly in
leather–covered or copper–covered vise jaws with the
Spindle (118) facing upward.
The Spindle Bearing Cap (120) has left–hand
threads.
4. Using No. 8SA32–26 or No. 141A12–26 Lower
Bearing Cap Wrench, unscrew and remove the
Spindle Bearing Cap.
For 6L2D6, remove the Spindle Seal (120A).
Withdraw the Socket Adapter Spindle Assembly (118)
from the Angle Housing.
5. Inspect the Lower Spindle Bearing (113) for looseness
or roughness. If either of these conditions exists,
replace the Bearing as follows:
For 7L3D6 Angle Head
a. Remove the Bevel Gear Retainer (114).
b. Press the Bevel Gear (105) from the Spindle.
c. Press the Lower Spindle Bearing from the Spindle.
For 6L2D6 Angle Head
a. Grasp the square drive end of the Spindle in
leather–covered or copper–covered vise jaws.
b. Unscrew the Bevel Gear Retainer (114) and lift
the Bevel Gear (105) off the Spindle.
c. Press the Lower Spindle Bearing from the Spindle.
Do not remove the Upper Spindle Bearing (104)
unless you have a new Bearing ready to install.
This type of Bearing is always damaged during the
removal process.
The 7L3D6 Angle Head will require a new Angle
Housing Cap (103) when the Upper Spindle
Bearing is installed.
6. If the Upper Spindle Bearing appears rough or loose,
press it from the Angle head.
7. Remove the Bearing Seat Retainer (108) and slide off
the Rear Thrust Bearing Seat (107), Bevel Pinion
Thrust Bearing (112) and Front Thrust Bearing Seat
(109) from the pinion shaft.
