MAINTENANCE SECTION

f.Press the Bevel Pinion Driver Bearing (33) onto the gear head end of the Bevel Pinion Driver (31).

g.Install the Internal Gear (32) over the gear head end of the Bevel Pinion Driver, making sure the splines of the Internal Gear mesh with the Planet Gear teeth.

h.Install the Thrust Spacer (38) over the threaded end of the Bevel Pinion Driver.

i.Press the Bevel Pinion Bearing (39) onto the Bevel Pinion Driver.

If the Pinion (40) needs to be replaced, replace both the Pinion and Bevel Gear. They are a matched set and cannot be matched with other Bevel Gears.

j.Check the Pinion for worn or broken teeth.

k.Screw the Pinion onto the threaded Bevel Pinion Driver and tighten to 14 to 19 ft–lb (19 to 26 Nm) torque.

For GRG15A, GRG15M or GRS15A Models:

a.Press the Bevel Pinion Bearing (39) over the threaded end and onto the Bevel Pinion Driver (31).

If the Pinion (40) needs to be replaced, replace both the Pinion and the Bevel Gear. They are a matched set and cannot be matched with other Bevel Gears.

b.Check the Pinion for worn or broken teeth.

c.Screw the Pinion onto the Bevel Pinion Driver and tighten to 14 to 19 ft–lb (19 to 26 Nm) torque.

d.Coat the inner surface of the Arbor Coupling (42), the spline of the Rotor (26) and the spline of the Bevel Pinion Driver with 3 to 4 cc of

IRAX No. 68–1LB Grease. Do not substitute any other grease.

e.Install the Arbor Coupling onto the spline end of the Bevel Pinion Driver.

f.Install the Thrust Spacer (38) over the Arbor Coupling (42) until it is against the Bevel Pinion Bearing.

2.Grasp the Angle Arbor Housing (43) horizontally in leather–covered or copper–covered vise jaws.

3.Slide the assembled Bevel Pinion Driver into the Angle Arbor Housing.

4.For GRG15A, GRG15M or GRS15A Models, next install the Motor Spacer (41).

Make sure the Throttle Lever Assembly (17) mounting boss on the Throttle Handle (1) aligns with the closed, upper portion of the Angle Arbor Housing.

For GRP15A–02P–7 Models, make sure the spline on the Rotor (26) properly engages the spline in the Rotor Pinion (35).

5.Slide the assembled Throttle Handle into the Angle Arbor Housing.

6.Clean the Coupling Nut (21) threads and carefully apply a uniform coat of Vibra–Tite** VC3 No. 205

to at least the first three threads. Allow the Vibra–Tite to cure for ten to twenty minutes before assembly.

Do not exceed 52.5 ft–lb (71.2 Nm) torque. The motor may be damaged if this torque is exceeded.

7.Using the No. 49843–147 Coupling Nut Wrench, install the Coupling Nut and tighten it between 48 to 52.5 ft–lb (64 to 71 Nm) torque.

Assembly of the Throttle Lever and Inlet

(Dwg. TPD662)

1.Assemble the Throttle Lever Assembly (17) as illustrated.

2.Align the holes in the Throttle Lever Assembly with the slots in the Throttle Handle. Using a soft hammer, tap the Throttle Lever Pin (16) into the Throttle Lever Assembly until it slightly protrudes from the opposite end. File off any sharp edges. Operate the mechanism to assure operation.

3.Grasp the flats of the Throttle Handle Assembly (1) in leather–covered or copper–covered vise jaws, air inlet up.
