FILLING PROCEDURE
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.
WARNING:
Use CAUTION when removing screws, air bleeder assembly (704153) and fill bottle assembly (745263). Hydraulic oil may
be under pressure.
CAUTION:
Before filling handle assembly, air piston assembly should be all the way down.
CAUTION:
When forcing piston rod assembly downward, with head cylinder assembly removed, hydraulic oil will eject forcibly from
handle assembly.
CAUTION:
When bleeding tool, ensure tubing is free from kinks or other obstructions.
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 545 or equivalent or a non
-
hardening Teflon® thread
compound such as Slic
-
tite®. Tighten until fitting feels snug and then continue to tighten 1/2 to 1 full turn.
CAUTION:
Over tightening
can easily distort the threads. DO NOT USE TEFLON® TAPE.
CAUTION:
Teflon® tape is an excellent thread sealer, however, if it is not
properly applied, pieces of Teflon® may enter the hydraulic system and cause a malfunction or damage.
1.
Put the piston rod wrench assembly (704149) into the top of handle assembly (704132), pushing down firmly until piston rod
assembly (704138) is completely in the down position.
2.
Fill oil passage and reservoir with Automatic Transmission oil Dexron® III or equivalent. The reservoir is the area surrounding
the power cylinder (751131). When looking at the top of the handle assembly (704132) the oil passage is the hole that has a
counter bore for o
’
ring (S832). Do not overfill causing oil to go in air passage hole.
3.
Re
-
install o
’
ring (S832), gasket (704129), button head cap screws (A
-
928) and manifold
-
handle (744303) to handle assembly (704132),
keeping hydraulic hose (A
-
336) towards plug (704313), located on handle assembly (704132). Torque button head cap screws
(A
-
928) to 40 inch lbs. (4.52 Nm).
4.
Push piston (751307) full forward. Install gasket (704129), o
’
ring (S832) and socket head cap screws (400061 & 400066) on manifold
-
head assembly (744306). Assemble head cylinder assembly (703124) to manifold
-
head assembly (744306). Apply Loctite® 242 to
all socket head cap screws and torque socket head cap screws (400061 & 400066) to 40 inch lbs. (4.52 Nm).
5.
Remove lever assembly (724017) from manifold
-
head assembly (744306).
Coil tool hoses up on bench and lay handle assembly
(704132) down on side so that the hole marked #4 on the manifold
-
handle (744303) is to the top. Set manifold
-
head assembly
(744306) over a small bucket or can. Completely fill up fill bottle (745263).
6.
Remove button head cap screw (402482) and stat
-
o
-
seal (S572) from manifold
-
handle (744303) hole #4 and manifold
-
head
assembly (744306) hole #4. Connect fill bottle (745263) to manifold
-
handle (744303) hole marked #4.
7. In one continuous squeeze force oil into manifold
-
handle (744303) until oil starts to flow from bleeder hole marked #4 on the manifold
-
head assembly (744306). While still squeezing the fill bottle (745263) use other hand to replace button head cap screw (402482)
and stat
-
o
-
seal (S572) on the manifold
-
head assembly (744306). Torque 35
-
40 inch lbs. (3.95
-
4.52 Nm) Do not over tighten. This
may require two people.
8. Remove fill bottle (745263) and replace stat
-
o
-
seal (S572) and button head cap screw (402482) on manifold
-
handle (744303) and
torque 35
-
40 inch lbs. (3.95
-
4.52 Nm) Do not over tighten.
9.
Proceed to bleeding instructions to remove air from hydraulic system.
