BACKHEAD DISASSEMBLY
Unscrew and remove the inlet bushing, No.867883, for inspec-
tion and cleaning of the air inlet screen, No.869171. Replace the
screen if clogged or torn.The throttle valve and related compo-
nents may be removed by unscrewing the valve caps, (2) No.
203362 and No. 203360. To remove solenoid, unscrew solenoid
retainer No. 203369. Remove flow valve, No. 203036, by un-
screwing with screwdriver.
REASSEMBLY
—GENERAL
All parts should be washed in a solvent and inspected for
damage or wear. Particular attention should be given to all
bearings, gears, gear pins, and rotor blades as failure of these
parts could cause damage to more expensive parts. Rotor
blades should be replaced every repair cycle or if they measure
less than 3/16" on either end.
Inspect and replace any "O" rings or seals that show signs of
wear or deterioration. During reassembly all parts should receive
a coating of No. 2 Moly grease. Reassembly of all of the various
sub-assemblies is in the reverse order of disassembly; however,
the following paragraphs list some of the more important reas-
sembly procedures.
"K" RIGHT ANGLE HEAD REASSEMBLY
Slip pinion needle bearing, No. 869864, (unstamped end first) on
the pinion, No. 202200, and press (press on the bearing's
stamped end) the bearing to a depth of 7/8" from the face of the
bearing bore. Install pinion ball bearing, No. 847846 and bearing
retainer, No. 863564, in the head and tighten retainer securely
using the 5/8" hex nut and 5/8" deep socket. Using a suitable
driver through the hole in the top of the head, drive the pinion
back to make sure it is seated properly in the head.
"M" RIGHT ANGLE HEAD REASSEMBLY
Assemble the spindle and related components in the head and
securely tighten (left hand threads) the bearing cap, No. 864396.
Use bearing spacer, No. 869050, to press the pinion needle
bearing, No. 863360, (press on the bearing's stamped end) in
the head. Install ball bearing, No. 847846, and bearing retainer,
No. 863564, in the head and tighten retainer securely using the
5/8" hex nut and 5/8" deep socket.
15° & 30° ANGLE HEAD REASSEMBLY
Install a pinion needle bearing No. 847746, on the pinion and
press (press on the bearing's stamped end) the bearing and
pinion assembly into the angle housing until the bearing bottoms
out against the shoulder in housing. Insert the needle bearing
spacer No. 869206, into the housing and press (press on the
bearing's stamped end) the rear needle bearing into the housing
until it bottoms out.
MOTOR REASSEMBLY
Assemble the rear rotor bear-
ing and rear bearing plate
(press on the bearing's inner
race) onto the rear rotor shaft
until there is approximately
.001" clearance between the
plate and rotor. Assemble the
five (5) rotor blades, cylinder,
front bearing plate, and front
rotor bearing (press on the
bearing's inner race) to the
rotor assembly. After final as-
sembly, the cylinder should be
held firmly, but not tightly be-
tween the two (2) bearing
plates and the rotor should
turn freely and not rub either
bearing plate.
SOLENOID ADJUSTMENT
If the solenoid No. 203363, is replaced or needs adjustment, turn
adjustment screw No. 863241, clockwise until it stops, then
back-off one full turn.
SAFETY CHECK
After repair or replacement of parts, tools equipped with an
automatic shut-off device should be tested to verify that the
device is functioning properly. The torque setting entered into
the torque control monitor must not exceed maximum torque
range of tool or the automatic shut-off device will not function and
the tool will operate as a stall tool. Operator should be prepared
to resist torque reaction until throttle is released.
.0015" (.038mm)
Clearance
Must be replaced if less than
3/16" (4.7mm) on either end.
