It is imperative that the slew encoder be adjusted anytime
work is done to the electrical swivel.
11. Activate all systems, cycle all functions, and observe for
proper operation. Adjust the slew encoder in accordance
with Slew Angle Zero Adjustment Procedure, page 6-22
in this Sub-Section.
Preventative Maintenance
It is recommended that a normal inspection of the electrical
swivel collector ring and brush assembly be established. An
example of this could be at approximately 100 to 150 engine
operating hours. When this time limit is reached, perform the
following.
1.
Check the collector ring and brush assembly for any
corrosion, pitting, arcing, and wear.
2.
Check the collector ring setscrews and ensure they are
tight.
3.
Check the brush and arm assembly springs. Ensure
they are holding the brushes firmly against the collector
rings.

SWING LOCK PIN
Description
T h e p u r p o s e o f t h e s w i n g l o c k p i n i s t o l o c k t h e
superstructure in position directly over the front for pick and
carry loads. The pin swing lock installation consists of a large
pin, a control handle in the right side of the cab, and control
linkage that allows the crane operator to set and free the pin.
When the superstructure is directly over the front or rear,
pushing the control handle down drops the swing lock pin
into a socket on the carrier frame, locking the superstructure
in place. Pulling the control handle up pulls the pin out of the
socket, unlocking the superstructure.
Maintenance
Ve r i f y l i n k a g e i s i n s t a l l e d t o a v o i d d a m a g e f r o m
superstructure rotation and is undamaged. Verify pin,
turntable bushing pin passes through, and socket on the
frame are undamaged. Verify all attaching hardware is
secure and undamaged.
Ensure linkage is adjusted properly. If it is, the pin bottom will
stick out about 5.89 cm (2.32 in) from the bottom of its
bushing in the turntable. (If it is too far in, it might not lock
properly. If it is too far out, it might hang up). Using the jam
nuts on the linkage parts, adjust the linkage so the pin bottom
will stick out about 5.89 cm (2.32 in) from the bottom of its
bushing in the turntable; verify the superstructure can lock
properly and the superstructure can rotate without lock pin
hang up.
360° SWING LOCK CONTROL (POSITIVE
LOCK TYPE) (OPTIONAL)
Description
The purpose of the swing lock is to secure the superstructure
in position at one of the positions in its rotation. There are
rou gh ly 12 0 s po ts ab out 3. 0 deg rees a part f or t he
superstructure to lock to in its 360 degree of rotation. The
360 degree swing lock foot pedal is on the left side of the
cab. Pushing the swing lock pedal down engages the lock
between the teeth of the swing gear. Pulling the swing lock
lever up disengages the lock.
Maintenance
Verify cable is routed to avoid damage from superstructure
rotation and is undamaged. Verify swing lock assembly is
u n d am a g e d a n d w o r k i ng p r op e r l y. Ver i f y s p r i n g i s
undamaged and has enough strength to pull blade of swing
