Assembly

Inspection
1. Bearing (18): Hold the center hub of the bearing
between your thumb and index finger. Roll the outer
surface against the palm of your other hand. Motion
should be smooth with no rough spots. If any
roughness is noted, replace the bearing.
2. Needle Bearings (4): Hold the motor cap or saw
head motor body in one hand, or place on a flat
surface. Insert drive shaft of idler shaft in the
bearing. Spin the shaft. The shaft and bearing
should turn smoothly. If any roughness is noted,
Greenlee Fairmont recommends replacing the saw
head motor body or motor cap as an assembly with
the bearings already pressed in.
3. Saw Head Motor Body (1) and Motor Cap (13):
Mating surfaces, gear cavities, oil passageways,
etc. in the components must be smooth and free of
grooves or nicks. If either component has grooves
or nicks, replace the component as an assembly
with the bearings already pressed in.
4. Drive Shaft (17) and Idler Shaft (15): All surfaces
must be smooth and free of grooves or nicks. If
either component has grooves or nicks, replace the
component.
5. Spool (10) and Sleeve (6): All surfaces must be
smooth and free or grooves or nicks. If either
component has grooves or nicks, replace the
component.
6. O-Rings: Always replace O-rings in components
that have been disassembled with new O-rings
during assembly. A packing kit is available that
includes all O-rings and gasket.
7. Gasket (14): Always replace gasket when motor
cap is removed from saw head motor body.
8. Drive Sprocket (41) and teeth must be not chipped
or broken. If the teeth are worn, all teeth must be
worn equally. If not, replace the sprocket. If the
sprocket teeth are worn and a new saw chain is to
be installed, install a new drive sprocket.
9. Guide Bar (44): Guide bar must be straight. The
rails and groove must not have excessive wear.
If it does, replace the bar.
10. Saw Chain (45): Saw Chain must not have exces-
sive wear, broken or damaged components.
If it does, repair or replace the chain.

Assembly
When assembling parts, refer to Parts illustrations
(page 28) for correct orientation and placement of parts.
Clean all parts with solvent, then dry with compressed
air. Do not expose O-rings or other packing components
to solvent for long periods of time.
Inspect all parts as they are assembled for signs of
damage, wear, cracks, etc. Do not install any parts
which appear to be damaged.
Apply clean hydraulic fluid or O-ring lubricant to all
O-rings and all metal surfaces which O-rings must slide
over. When installing an O-ring over a sharp edge, use a
rolling action to avoid damage to the O-ring.
Wherever assembled parts are metal-to-metal contact,
coat the surfaces with clean hydraulic fluid or O-ring
lubricant.
Saw Head and Motor
1. Install a new O-ring (3) in the saw head motor body
(1) using an O-ring tool. Be careful not to damage
the O-ring during installation.
2. Install the two dowel pins (22) in the saw head
motor body, if they were removed. Install the gasket
(14).
3. Press the bearing (18) on the drive shaft (17).
Generously lubricate the drive shaft and install the
drive shaft and bearing in the saw head motor body.
Press the bearing into place. Secure with a 1-3/8
inch internal ring (19).
4. Install the Woodruff key (20) and one gear (21) on
the drive shaft (17).
5. Install the drive pin (16) in the idler shaft, if it was
removed. Slide one gear (21) on the idler shaft (15).
Install the idler shaft with the gear (21) in the saw
head motor body.
6. Install the motor cap (13) on the saw head motor
body (1) aligning the scribe marks that were made
during disassembly.
7. Secure the motor cap using eight 1/4 x 1 inch
socket head cap screws (23). Torque the cap
screws to 80 inch-pounds. (See Figure 19 for
torquing sequence.)
Metering Screw
Install a new O-ring (24) on the metering screw (25).
Install the metering screw (25) in the saw head (1).
