ASSEMBLY/INSTALLATION
1. See Figure 3-129. Install oil pump drive gear and pinion
gear on pinion shaft.
a. Install shaft key into pinion shaft slot.
b. Slide oil pump drive gear over pinion shaft. Drive
gear must align with shaft key.
c. Align keyway in ID of pinion gear with shaft key.
d. Slide pinion gear over shaft key and against oil
pump drive gear.
2. See Figure 3-126. Install pinion nut.
a. Clean threads on pinion shaft and nut.
b. See Figure 3-130. Install CRANKSHAFT LOCKING
TOOL (Part No. HD-43984) to gearcase with “Side

c. Apply several drops of LOCTITE 271 (red) to last
few threads of nut.
d. Install nut to pinion shaft. Tighten nut to 19-21 ft-lbs
(26-29 Nm) plus an additional 15
º to 19º rotation.
3. See Figure 3-126. 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.
NOTES
● The XB uses “V” style timing marks on the front intake
cam assembly. Please note the “V” design.
● Because of the larger diameter additional gear (which
meshes with the pinion gear) on the outboard end of the
cam, the front exhaust cam gear and the rear intake cam
gear must be installed before the front intake cam gear is
installed.
4. See Figure 3-126. Install a new seal and new dry gear
cover gasket on crankcase.
