LUBRICATION
Each time a 1 Series Drill or Angle Drill is disassembled
for maintenance and repair or replacement of parts,
lubricate the tool as follows:
1. Gearing
For 2100 rpm or more, coat gears with 2 to 4 cc of
Ingersoll-Rand No. 28 Grease.
For models below 2100 rpm, coat gears with 4 to 6 cc
of Ingersol1-Rand No. 28 Grease.
2. Angle Head
Inject 2 to 4 cc of Ingersoll-Rand No. 67 Grease into
the Grease Fitting (101).
3. Use Ingersoll-Rand No. 10 Oil for lubricating the
motor. Inject approximately 1 to 2 cc of oil into the air
inlet before attaching the air hose.
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 Tool
1. Each 1 Series Drill is comprised of three modules or
units. In-line and Pistol Drills have a motor housing
and motor unit, a gear unit and a drill chuck spindle
unit. Angle Drills have a motor housing and motor unit,
a gear unit and an angle attachment unit. The tool can
be disassembled for repairs to each individual unit
without disturbing the other units.
2. For Pistol and In-Line models: to remove Drill
Chuck (51), lightly grasp the tool in a copper-covered
vise using the flats on the Gear Case (38). Insert the
Chuck Key into one of the holes in the Chuck and tap
lightly with a hammer. Remove the Drill Chuck Spacer
(50).
3. For Models 1LJ1A1 and 1LL1A1, to remove the
Angle Attachment, use two wrenches to unscrew the
Coupling Nut (111) from the Gear Case and lift off the
entire angle attachment.
MAINTENANCE SECTION
4. Using two wrenches, unscrew and remove the Gear
Case from the Motor Housing (1).
Disassembly of the Angle Attachment
1. Carefully grasp the Angle Head in copper-covered vise
jaws so that the Spindle is facing upward.
2. Using a wrench, remove the Spindle Bearing Cap
(110).
This is a left-hand thread.
Do not remove the Spindle (102) from the Angle Head
until the Bevel Pinion (102) is pulled outward against
the Bevel Pinion Thrust Bearing (106). Failure to do
so could damage the Spindle Upper Bearing (103),
making it impossible to remove the Bearing from the
Spindle. Also, the Bevel Pinion could be damaged. If
tightness or binding occurs, check to make sure the
Bevel Pinion has been pulled outward.
3. Pull the Spindle from the Angle Head.
4. Inspect the lower Spindle Bearing (109) for looseness
or roughness. If either of these conditions exist, press
the Bearing from the Spindle.
5. If the Spindle Upper Bearing (103) appears rough or
loose, press it off the Spindle.
6. Remove the Thrust Bearing Retainer (107), Rear
Thrust Bearing Seat (108) and Bevel Pinion Thrust
Bearing (106) from the Bevel Pinion (102) shaft.
7. Grasp the spline of the Bevel Pinion shaft in
leather-covered or copper-covered vise jaws. While
pulling on the Angle Head, tap the rear face of the Angle
Housing with a soft hammer to pull the Bevel Pinion and
Bevel Bearing (105) from the Angle Housing.
Do not remove the Bevel Pinion shaft and Bevel
Pinion Bearing unless you have a new Bearing on
hand.
After the Angle Head is disassembled, check all parts
for damage or wear.
8. If the gear teeth on either the Spindle or Bevel Pinion
are worn or chipped, replace both parts.
These gear sets are furnished in a matched set and
must be replaced as a matched set.
Disassembly of Gearing
1. Using a thin blade screwdriver, work the Motor Clamp
Washer Retaining Ring (37) from the groove in the
Gear Case and withdraw the Motor Clamp Washer (36).
2. For Models 1P44, 1P21, 1P13, 1P09, 1P06 and
1LJ1A1, tap the motor end of the Gear Case against
the top of the workbench to remove the Gear Head
(42), Gear Head Spacer (41), Drive Plate (43) or Gear
Head Planet Gears (44).
For 1P76, 1P21 and 1P13, remove the Rotor Pinion
(45).
