STROKE LIMITER INSTALLATION INSTRUCTIONS
WARNING:
Stroke limiters are designed for the protection of the operator and equipment. Failure to operate tool without the
proper stroke limiter will result in damage to the nose assembly or tool and may result in personal injury.
WARNING:
Do not cycle tool without air bleeder assembly (704153), or the screw and stat
-
o
-
seal, installed in tool head. Severe
personal injury could result.
CAUTION:
Before filling handle assembly (722132), air piston assembly (704121) must be all the way down.
CAUTION:
When forcing piston rod assembly (731333) downward, with head cylinder assembly (731199) removed, hydraulic oil will
eject forcibly
from handle assembly (722132).
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.
CAUTION:
Use CAUTION when removing screws, air bleeder assembly (704153) and fill bottle (745263). Hydraulic oil may be under pressure.
Note:
•
If you are unsure your nose assembly requires a stroke limiter, contact Gage Bilt for assistance.
1. Cycle tool to the rear position and disconnect air.
2. Remove end cap (731417).
3. Install stroke limiter over rear of piston assembly (731211). See nose assembly selection chart to select stroke limiter.
4. Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from front bleeder hole.
5. Install end cap (731417) and torque to 45 foot lbs. (61Nm). Oil will drain from front bleeder hole during installation.
6. Attach button head cap screw (402482) and stat
-
o
-
seal (S572) to front bleeder hole and torque to 35
-
40 inch lbs. (3.95
-
4.52 Nm). Do not
over tighten.
7.
Connect tool to air and using a pair of dial calipers, check for full stroke using instructions a thru c below. (See stroke limiter chart below).
a. With actuator lever assembly (704343) released, check dimension
“
A
”.
b. While holding actuator lever assembly (704343) check dimension
“
B
”.
c. Subtract dimension
“
A
”
from dimension
“
B
”.
If stroke is not consistent within 1/64 (.396 mm) (see stroke limiter chart below), DISCONNECT AIR SUPPLY, remove button head cap
screw (402482) and stat
-
o
-
seal (S572) from front and rear bleeder holes.
8. Insert a
1/4”
Allan wrench in back of piston (731211) and manually push the piston (731211) full forward until dimension
“
A
”
checks correct.
Replace stat
-
o
-
seal (S572) and button head cap screw (402482) into front and rear bleeder holes. Torque to 35
