oughly clean gearcase cover, removing all metal chips/
shavings. Blow out all oil passages using compressed
air.

ASSEMBLY/INSTALLATION

1.

See 

Figure 3-68.

 Install oil pump drive gear (5) and pin-

ion gear on pinion shaft. 

a.  Slide oil pump gear drive gear (5) over pinion

shaft (1). Drive gear must align with shaft key (4).

b. 

Align keyway (3) in ID of pinion gear with shaft
key (4). 

c.  Slide pinion gear over shaft key (4) and against oil

pump drive gear (5).

2.

See 

Figure 3-59.

 Install nut (11). 

a. 

Clean threads on pinion shaft and nut. 

b. 

See 

Figure 3-69.

  Install CRANKSHAFT LOCKING

TOOL (Part No. HD-43984) to gearcase with “Side
A” facing out, over pinion shaft, with two screws. 

c. 

Apply several drops of LOCTITE THREADLOCKER
262 (red) to threads of nut. 

d.  Install nut to pinion shaft. Tighten nut to 35-45 ft-lbs

(48-61 Nm).

3.

Liberally apply engine oil to bushings, shafts, and gears.
Install all cam gears into bushings of right crankcase
half, properly aligning timing marks of cam gears and
pinion gear. See 

Figure 3-62.

NOTE

Because of the larger diameter additional gear (which
meshes with the pinion gear) on the outboard end of the rear
intake (15-2) cam gear, the rear exhaust (15-1) and front
intake (15-3) cam gears must both be installed before the
rear intake (15-2) cam gear is installed.

CAUTION

Use only the correct gearcase cover gasket (see parts
catalog for Part No.). Using pre-2000 model year gasket
will obstruct oil galley and result in engine damage.

4.

See 

Figure 3-59.

  Install a 

new

  seal (6) and 

new

  dry

gearcover gasket (9) on gearcase cover (17).
