gear section from machine. Slide the motor
package from the unit. Disassemble the motor
package to check for wear in the cylinder liner
and to examine the motor blades. Install new
blades if the old blades show excessive wear.
Install cylinder on the end plate; check blades
(20) for proper placement; install the front bearing
support (22). Slide the motor package in place,
carefully dropping the dowel pin # 8010126
(assembled in the rear end of the cylinder) into
the locating hole at the bottom of the case. The
gear case of the 600 RPM tool is a standard two-
stage planetary system and disassembly and
reassemble of the unit is very simple.
Slide the gears from the gear case, clean,
inspect, re-grease and reinstall in the gear
case. Slide the gear case into the housing and
install dowel pin (39).
Reinstall the torque unit on the motor case.
(When installing the cam section on the motor
housing, be sure to depress the trip so the fol-
lower will not jam on the top side of the opera-
ting cam while aligning front case with the
motor.) Once the torque case is aligned in the
motor housing and the screws are installed, the
trip can be released. Before reinstalling the
valve cover, push forward on the operating lever
(11), and manually depress the trip. In depres-
sing the trip with the finger. the valve (SA) will
slide forward. Simulating the operation of the
tool at shut-off. By pulling back on the lever (11).
the outer valve that surrounds the valve (SA),
should slide into the rearward position before
valve (SA) moves within. If the outer valve is tight
to the degree of sticking in the bushing (1) the
motor would run forward rather than in reverse,
causing over-rolling of joints. It is therefore
essential that the outer valve be free in the
bushing.
After the above checks have been made, rein-
stall the valve cover. Ensure adequate lubrica-
tion of al parts during reassembly.
