Also check the hydraulic system for excess contamination
in the fl uid and for fi lter condition. Operating conditions
may require changing from a 25-micron fi lter to an over-
sized 10-micron fi lter.
TOOL REASSEMBLY
1. Lubricate and install a new o-ring (5) and back-up ring
(26) into the main housing. Install the seal back-up washer
(34) and retaining ring (16).
2. Slide the reversing spool into the main housing assem-
bly. Insert the spool with the slot toward the idler shaft hole
and the narrow side of the depression in the spool facing
up toward the top of the main housing.
3. Insert the idler shaft (48) with spring (50) and plunger
(49) to prevent the reversing spool from turning.
4. Lubricate and install new wiper seals (70), o-rings (12),
back-up rings (17), and o-rings (3) into each seal cap (71).
Install each seal cap onto the main housing assembly.
5. Install each end cap (72) and secure withretaining ring
(74).
6. Lubricate the seal area of the main shaft (37) and install
it into the main housing. Install the idler gear (35) onto the
idler shaft.
7. Lubricate and install a new o-ring (11) onto the motor
cap (36). Lubricate the bolt (29) threads with an antiseize
compound and install the motor cap with lockwasher (4).
Tighten the bolts to 15-17 ft. lb./20-23 Nm in a cross pat-
tern.
CAUTION
Do not force parts together.
8. Lubricate and install a new seal wiper (67) into the trig-
ger mount (82). Secure trigger (81) to trigger mount with roll
pin (21). Install the trigger assembly to the main housing
with bolts (8) and lockwashers (22).
SERVICE
9. Install a new o-ring (19) in main housing and new o-ring
(18) on valve spool. Lubricate the valve spool bore and
seals with grease before installing the valve spool (65) into
the main housing from the spring cap end. Do not install
the valve spool from the trigger side of the main housing as
this will result in spool seal damage. Ensure that the tab on
the valve spool nose is aligned with the slot in the trigger.
Install spring (83) behind the valve spool. Using Loctite™
242, install spring cap (73) to main housing.
10. Lubricate with grease and install the bearing races (32)
and thrust bearing (33). Install the spacer (47) with the
smaller stepped diameter facing the main housing.
11. Install the impact mechanism. Tighten bolts (8) with
lockwashers (22) to 48 in. lb./5.4 Nm. If a trigger guard (43)
