PTO ClUTCH TROUBLESHOOTING
1. ELECTRICAL DATA-
a. See wiring diagram in Section
2 of this manual.
2. CLUTCH DOES NOT
ENGAGE-
a. Check electrical system for
broken wires or bad connections.
b. Check voltage at clutch lead.
Vottmeter should read more than
10 votts. If vottmeter does not
register a reading, look for broken
wires or connect clutch lead and
check resistance reading of clutch
coil. A normal resistance reading
should be between 3.0 and 2.3
ohms. A reading outside these
values indicates a fautty coil. The
field assembly should then be
replaced. Check armature/ rotor
gap. this is done by inserting a
feeler gauge in the four (4) slots
provided in the brake flange. The
gap should be between .010 ·-
.020" (0.25mm-0.51 mm) wtlh the
clutch/brake swtlch in the "off"
postlion. If the gap is greater, re-
adjust brake as described in
"Maintenance" (below).
3. ENGINE DRIVEN
ATTACHMENT ROTATES
SLOWER THAN NORMAL-
a. Check for loose betts.
b. Inspect engine driven
attachment wtlh clutch batt
removed. Attachment should turn
freely.
c. Check clutch/brake pulley grooves
for grease or oil.
d. Check clutch/brake worl<ing
surfaces for grease or oil.
NOTE: REMOVE GREASE OR
OIL FROM CLUTCH/BRAKE

PTO ClUTCH MAINTENANCE
If the clutch/brake has not been
used over a long period of time,
the following procedure is
recommended prior to tls use:
a. PosHion transmission in
neutral position.
b. Start tractor engine and put
throttle in 'FAST' position.
c. Turn clutch/brake switch on
and off six times, engaging and
disengaging driven attachments.
NOTE: ALLOW ENGINE
DRIVEN ATTACHMENTS TO
COME TO A COMPLETE STOP
BETWEEN ON-OFF CYCLES.
The clutch/brake is now ready for
continuous, trouble-free duty.
