exposed during disassembly can be replaced.

PRIOR TO REASSEMBLY

1.  Clean all parts with a degreasing solution.

2.  Blow dry all parts or use lint-free cloths.

3.  Ensure that all seals exposed during disassembly are

TOOL DISASSEMBLY

GEAR HOUSING

1. Remove the chuck (33) from the output shaft (36) by 
holding the seal nut (35) with an open end wrench and turn-
ing the chuck counter-clockwise.

2.  Remove the capscrews (31) and lockwashers (32) se-
curing the gear housing (69) to the main housing assembly 
(76). If the tool has a trigger guard (80), remove capscrew 
(34), nut (20) and trigger guard before removing the gear 
housing.

3. Remove the ring gear (27), roll pin (5) and gasket (71).

4. Remove the retaining ring (29) near the planet shafts 
(23) before removing the planet shafts. Remove the seal 
nut (35) by using the planet shaft holes to keep the output 
shaft from turning. Pull the output shaft with  attached parts 
from the gear housing.

5.  Remove the planet gears (26) from the output shaft. 
Inspect shafts, gears and gear bore bushings (see CLEAN-
ING AND INSPECTION procedure).

6.  Spin the ball bearing (28) on the output shaft. The bear-
ing should turn smoothly. To replace the bearing, support 
the outer race and press down on the output shaft from the 

chuck end. Do not reuse the ball bearing once it has been 
removed from the output shaft.

7.  Remove the output shaft seal (30) by pressing it from 
the gear housing bore.

8.  Check the end faces of the seal nut and output shaft for 
nicks and war (see CLEANING AND INSPECTION proce-
dure).

MOTOR CAP

and push the valve spool (59) out the spring cap end of the 
main housing.

TRIGGER

15.  Remove the trigger by fi rst removing the capscrews (8) 
and lockwashers (32) and removing the trigger and trigger 
mount (78) as an assembly. Drive out the roll pin (21).

REVERSING SPOOL

16.  Remove the retaining rings (67) and end caps (65).
