the handle, torque to 20  foot-pounds (27.1 
N·m), pull  the trigger lever  to be sure there is 
a minimum amount of trigger play present 
before actual "triggering" occurs.  If too much or 
too little trigger play is present, it is necessary 
to  disassemble the trigger mechanism, alter 
the overall 5.120" (130 mm) length dimension 
as required and  then reassemble the trigger 
mechanism. 

 

d. Install new o -ring  seal (2) in its groove in 

dowel tube (13)  and install  the dowel  tube in 
handle  (12).  Apply Henkel Corporation, 
L o c t i t e   2 7 1 ,   to the threads of screws (1) and 
secure the handle assembly to cylinder (47) 
with the screws. Torque the screws to 25 foot-
pounds (34 N•m). 

 

e.  Apply Teflon sealing tape to the threads of  the 

oiler and hose  assembly.  Screw  oiler  and 
hose assembly (49) into handle (12)  and 
torque to 25 foot-pounds (34 N·m).   

 

6-4.12 REASSEMBLY AND INSTALLATION OF 

TOOL RETAINER ASSEMBLY 

 

a.  Insert front bumper washer (19) (chamfer side 

first)  into cylinder (47) and then front bumper 
(20). 

 

b.  Insert balls (18) into holes in retainer body 

(21). To retain the balls in the retainer body 
it  may be necessary  to apply a small 
amount of Chemplex 

710 

Silicone 

Grease, FUCHS Lubricants Company, Harvey 
IL. 60426. 

 

c.  Install release ring (17) and release ring spring 

(16) over retainer body (21).  Apply Henkel 
Corporation, L o c t i t e   2 7 1 ,   to the threads of 
the retainer body and then screw the retainer 
body onto cylinder (47).  

 

d.  Install retainer service tool (15) into retainer 

body (21) by pulling back release ring (17), 
inserting the retainer service tool with the ball 
recesses entering the retainer body, and then 
release the release ring.  Rotate the retainer 
service tool until balls (18) engage the recesses 
locking the retainer service tool in the retainer 
body.  Insert a tool bit through the hole in the 
retainer service tool and firmly tighten the 
retainer body into cylinder (47).  Pull back the 
release ring and remove the retainer service 
tool.   

 

e.  Install setscrew (38) and (43) hand tight into the 

cylinder (47) using Henkel Corporation, 
L o c t i t e   2 7 1 , on the threads.

6-5   OILER AND HOSE ASSEMBLY REPAIR 

 

6-5.1 DISASSEMBLY OF OILER AND HOSE 

ASSEMBLY. 

 

a. After 

the 

oiler  and hose assembly has  been 

unscrewed from  the Pakhammer, unscrew 
connector (1, Figure 6-2) from ferrule. 

 
b.  Only if hose (3) or either ferrule (2) is damaged 

and necessitates replacement should the 
ferrules be removed from  the hose. If removal 
is necessary, hold hose firmly and unscrew the 
ferrule(s) (left hand thread). 

 
c. Unscrew 

fill 

screw (part of  full screw and  cable 

assembly) (5) from housing (6) and drain oil 
from the housing. 

 
d.  If the fill  screw and cable assembly are 

damaged, carefully pry drive screw (4) out of 
the housing. 

 
e. Unscrew 

housing 

(6) 

from 

inlet 

(12). 

Remove 

and discard o -ring seals (7 and 8) only if 
replacements are  available.  If  replacements 
are not available and the old seals are worn, 
cut or otherwise damaged, they may result  in 
oil leakage  from  between  the  housing and 
inlet but must be reused until replacements 
become  available.  Inspect the  housing and 
inlet for damaged or worn threads, cracks and 
other similar damage that may result in oil 
leakage. Inspect the inlet for wear or damage 
to the quick disconnect end. 

 

f. Unscrew 

filter 

screw 

(9), carefully pull out filter 

disc (10)  and o-ring seal  (11).  Discard  the filter 
disc and o-ring seal only if replacements are 
available. If replacements are not available the 
old filter disc and o-ring seal must be  reused 
until  replacements become available.  Be 
sure the orifice in the filter disc is clear and 
not obstructed.  Clean as required. 

 
6-5.2 REASSEMBLY OF OILER AND HOSE 

ASSEMBLY. 

 

a.  Insert new o-ring seal (11) and new filter disc 

(10) in recess in inlet (12) and secure in position 
with filter screw (9). 

 

b.  Install new o-ring (7 and 8) in recesses in inlet 

(12). Screw housing (6) onto the inlet being 
careful not to displace the o-ring seals. 

 

c.  If drive screw (4) was removed, install drive 

screw through the eyelet on fill plug and cable 
assembly (5); carefully drive into housing (6).
