Disassembly; Assembly - Reliable Equipment LR 88.5 Operator's Manual

CHAIN AND MOTOR ASSEMBLY
WARNING
Complete disassembly is not recommended. Return the unit to an authorized dealer
for total disassembly and/or repair.
All maintenance or disassembly should take place on a flat, clean work surface covered
with towels or wipers so as to have a clean space for the disassembled parts.
Inspect each part during disassembly for wear, scratches, and cuts. Discard the worn
or damaged parts and replace with new parts.
O-rings are sensitive to sharp edges. Inspect closely for cuts or damage. A small cut
will cause a leak. When assembling or disassembling O-rings, use hydraulic fluid as
a lubricant to help disassembly or installation.
MOTOR AND BLADE ASSEMBLY
Adjusting and installing saw chain is an ongoing task. Fig. 6 may be found on page 16.
See Fig. 6 exploded view as a reference to explain this procedure. Start by removing
two hex bolts (6) and pull off cover (7). This exposes the blade assembly for
maintenance, adjustment, and replacement of the chain blade. Inspect and clean oil
groove (14) to allow for correct chain lubrication. Remove saw chain (2), adjusting
screw (5), chain adjuster (4), and chain bar (3). Remove lock nut (8). This allows for
the removal of: (9), (10), (11) and (12) from drive shaft (13).
See Fig. 5 for motor disassembly. Remove 8 screws (18) and lift motor cap (17) off.
Remove motor gears (14), gasket (16) and idler shaft (15). Bearings (12) and (13)
should not need to be removed unless extreme wear has occurred. Bearing
replacement would be a factory function only.
Remove lubricator screw (9) and O-ring (8). This completes disassembly of the motor
head, chain, and chain guide bar.

DISASSEMBLY

Before any disassembly, disconnect hoses from the Chainsaw!
Any residual pressure within the unit can and will spray at high
velocity, injuring the person doing the disassembly. Hot or
pressurized hydraulic fluid will cause serious injury to the body!
Accidental movement of the chain can cause serious injury,
dismemberment of a hand, finger or any other part of the body.
