SECTION 3. INSTALLATION AND
OPERATION
NOTE: IMPROPER INSTALLATION AND
ALIGNMENT IS THE GREATEST CAUSE
OF GEAR FAILURE. PLEASE FOLLOW
INSTRUCTIONS CAREFULLY.
3.1 UNCRATING AND HANDLING
Tapped holes have been provided for insertion of
eyebolts to aid in handling the unit. Average
weight of HY-7700 is 1230 lbs.
Check parts for shortage and any damage that
may have occurred (the parts information section
may be used as reference). Report immediately
any shortage or damage to your local distributor,
transfer agent or Capitol Gears.
3.2 INSTALLATION PREPARATION
SPECIAL TOOLS REQUIRED
1.
Chain hoist or equivalent
2.
Straight edge
3.
Feeler Gauge
4.
Thousandths dial indicator
To insure proper alignment of driving members it
is recommended that engine flywheel housing,
flywheel, oil dam adapter, and stub shaft be dial
indicated to insure trueness.
1.
(Fig.3A) Dial indicates the bolt face
of the engine flywheel-housing
flange. Rotate engine flywheel.
Record reading. Face deviation
must not exceed a total indicator
reading of .007 inch.
2.
(Fig.3B) Mount indicator with stern
riding on flywheel housing bore as
shown. Rotate flywheel and record
reading. The bore eccentricity must
not exceed a total indicator
reading of .007 inch.
3. (Fig.3c) Mount indicator to flywheel
housing so that stern is on inner face of
flywheel; record deviation of face run
out. It must not exceed a total indicator
reading of .007 inch.
4. (Fig.3D) set stern to ride on the pilot
bore of the engine flywheel as shown.
Record reading. Pilot bore eccentricity
must not exceed a total indicator
reading of .007 inch.
The sum of all readings in steps 1 through 4
must not exceed .007".
NOTE:
Keep all mating surfaces clean. Use
cleaning solvent or diesel fuel.
5.
Remove the clutch assembly from
the clutch-driving drum and drive
flange assembly (drive flange and
flywheel adapter).
6.
Remove clutch-driving drum from
flywheel adapter (Leave drive
flange attached to flywheel
adapter).
7.
Thoroughly clean flywheel adapter
to engine flywheel-mating surfaces
and secure flywheel adapter (and
drive flange) to engine flywheel with
capscrews and lock washers.
8.
Locate oil dam adapter on engine
flywheel housing with drain slots
down. Secure oil dam tentatively
with capscrews and lockwashers.
