5. Apply a small drop of Loctite No. 601 to the small
outside diameter of the spindle upper bearing shaft on
the Spindle (102).
6. Apply 2 to 3 cc of grease to the Spindle Upper Bearing
(103) and a light coat of grease to the gear teeth on the
Spindle. Press the Spindle Upper Bearing onto the
Spindle and allow the Loctite to dry a minimum of ten
minutes.
Do not get any Loctite in the bearing; damage to
the Bearing could result. Do not get any on the inside
diameter of the Bearing; grease will prevent the
Loctite from working.
7. Insert the Spindle into the Angle Head until the Spindle
Upper Bearing seats into the recess of the Angle Head.
Make sure that the Bevel Pinion is pulled outward
toward the Bevel Pinion Bearing before inserting the
Spindle into the Angle Head.
8. Slip the Lower Spindle Bearing over the end of the
Spindle and into the angle head recess.
9. Install the Spindle Bearing Cap (110) finger tight.
10. Spindle must turn freely.
11. While holding the Bevel Pinion out of engagement with
the Spindle, measure the amount of end play in the
Spindle. Subtract .002" (.051 mm) from the reading to
determine the required shim thickness.
12. Unscrew and remove the Spindle Bearing Cap. While
pulling the Bevel Pinion outward toward the Bevel
Pinion Bearing, remove the Spindle from the Angle
Head.
13. Insert the required number of shims, as determined in
step (11) into the upper bearing recess of the Angle Head.
Shim Packet contains three .002" (.05 mm) shims
and two .005" (.13 mm) shims.

14. Reassemble and test the Angle Head as indicated in
steps (6) through (12).
15. Once proper shimming has been achieved, remove the
Angle Housing Cap, clean the threads on the Angle
Head and the Angle Housing Cap, and apply a film of
Vibra-Tite ** VC3 to the threads.

16. Install the Angle Housing Cap and tighten to 35 in-lb
(3.9 Nm) torque.
17. Install the Rear Thrust Bearing Seat (108)
bevel pinion shaft with the flat face against the Thrust
Bearing.
18. Slide the Coupling Nut Retainer (112) and the Coupling
Nut (l l l), threaded end trailing, over the notched end of
the Angle Housing.
19. Compress the Coupling Nut Retainer, and work it into
the internal groove in the unthreaded end of the
Coupling Nut.
Assembly of the Tool
1. Apply some grease to the spline of the rotor shaft and
screw the Gear Case and components into the Motor
Housing. Tighten to 15 to 18 ft-lb (20 to 25 Nm) torque.
This is a left-hand thread.
2. For Models 1LLlAl and 1LJlA1, align the pin in the
Rear Thrust Bearing Seat with the notch in the Gear
Case (38) and screw the Coupling Nut onto the Gear
Case. Tighten to 18.4 to 22.1 ft-lb (25 to 30 Nm) of
torque.
This is a left-hand thread.
3. For all other models, slide the Drill Chuck Spacer (50)
over the threaded end of the Drill Chuck Spindle and
install the Drill Chuck (51).
