the manual oiler assembly from the top of the valve
handle.
3. Using snap-ring pliers, remove the retaining ring,
then remove the washer and coil spring. Push the
plunger out of the oiler plug. Remove and discard
all O-rings.
Note: The two holes in the small diameter section
of the oiler plug should be open for proper oiler
function.
REASSEMBLY

Lubricate and install the O-ring in the oiler plug bore.
2.
Lubricate and install the O-ring on the plunger seat.
Lubricate the plunger and push into the oiler plug
from the end opposite the hex.
3. Install (in this order) the coil spring, washer, and
retaining ring on that portion of the plunger protruding
from the hex end.
4.
Lubricate and install the two O-rings on the oiler plug.
Install the manual oiler assembly in the valve handle

HYREVZ MOTOR REPAIR
REMOVAL
1.
Remove the two bar clamping nuts and washers,
chain guard, saw bar, and chain.
2.
Remove the motor shaft jam nut (LH thread) by
clamping the drive sprocket so that it cannot rotate
(a chain type vise-grip works best).
3. Remove the sprocket, sprocket key and spacer.
4.
Remove the four capscrews securing the chain saw
adapter to the valve handle assembly, sepa rate
these assemblies.
5. Insert a hooked instrument through the oil tubes and
pull them out. Take care to avoid damaging the oil
tube bores in the motor and valve handle.
6. Remove the two oval head machine screws to
allow the motor to be withdrawn from the chain saw
adapter assembly.
DISASSEMBLY
Note: The saw can have either a two- or three- piece
Hyrevz™ Motor. Identify the motor used on your saw
1.
Place the motor in a vise (with soft jaws or V- blocks)
around the bearing end, output shaft down.
2.
On three-piece motors, scribe assembly marks
across the bearing retainers and the gear housing.
Make sure that the marks will be visible during
reassembly.
3. Remove the eight socket head capscrews se curing
the bearing retainers and the gear housing.
4.
Pry the rear bearing retainers or gear housing away
from the mating part. Be careful to lift the retainer or
housing straight off. Use the inside groove provided
at the split between parts to prevent scratches on
the surfaces between the parts.
5. On three-piece motors, pry the gear housing
assembly away from the front bearing housing in the
same manner as described in Step 4.
6. Remove the two gears, motor shaft key (or roller)
and the idler shaft.
7.
Remove the large face seal O-ring(s); being careful
not to damage the O-ring grooves or sur rounding
surfaces.
8. To remove the motor shaft from the front bearing
retainer or bearing housing, remove the large
retaining ring securing the ball bearings. Place the
retainer or housing on a flat surface with clear ance
for bearing removal. Push on the small end of the
motor shaft until the shaft and bearing(s) slide free.
Be careful not to bend the motor shaft.
9. The ball bearing(s) should be removed from the
motor shaft only if they must be replaced because
damage can occur during removal. To remove the
bearings from the motor shaft, press on the threaded
end of the motor shaft while supporting the outer
race of the bearing(s). Dis card the bearings.
10. Remove the retaining ring at the bottom of the ball
bearing bore to service the motor shaft seal(s).
11. To remove the seal liner and associated parts on
current two and three-piece motor assemblies,
