REASSEMBLY - GENERAL
All parts should be washed in a solvent and inspected for
damage or wear. Particular attention should be given to all
bearings, gears, gear pins, and rotor blades as failure of
these parts could cause damage to more expensive parts.
Rotor blades should be replaced at every repair cycle or if
they measure less than 3/16" on either end.
Inspect and replace any "O" rings or seals that show signs
of wear or deterioration. All gears, gear pins, and open
bearings should receive a generous amount of NLGI 2-EP
grease during reassembly. When assembling the gear case
to the backhead, the gear case should be torqued to 300/325
in. lbs. (33.9/36.7 Nm). Reassembly of all of the various sub-
assemblies is in the reverse order of disassembly; however,
the following paragraphs list some of the more important
reassembly procedures.
SERVICE INSTRUCTIONS
CLUTCH REASSEMBLY
During reassembly of the clutch, all parts should receive a
thin coating of a mixture of 10W machine oil and NLGI 2-EP
grease. All parts installed into the clutch spindle and clutch
cam should be checked for smooth operation before com-
plete assembly of the clutch.
MOTOR REASSEMBLY
Install the rear rotor bearing, No. 847609, into the rear
bearing plate. Press the bearing plate assembly (press on
the bearing's inner race) onto the rear rotor shaft until there
is approximately .0015" clearance between the rear bear-
ing plate and rotor.
Install the cylinder with the slotted end toward the front
bearing plate.
