Crankcase Halves
Lubricate all parts with Harley-Davidson 20W50 engine oil,
and proceed as follows:
1. See Figure 3-87. The original retaining ring (3) is left in
place to avoid damaging the bearing bore of the left
crankcase half (6). Verify that gap in retaining ring is
aligned with oil supply hole in bearing bore of left crank-
case half.
NOTE
See Figure 3-87. USE SPROCKET SHAFT BEARING
OUTER RACE INSTALLATION TOOL (1-2 Part No. HD-
39458) to install left and right outer races (4, 5) of sprocket
shaft tapered roller bearings into left crankcase half (6).
Always install left outer race (4) prior to installing right outer
race (5); the installer base (1) is usable only when you follow
this sequence of race installation.
2. Insert "SPORTSTER" end of installer base (1) into
inboard side of left crankcase half (6) bearing bore until
base contacts installed retaining ring (3).
3. Position left outer race (4) over bearing bore on outboard
side of left crankcase half (6).
4. Insert shaft of installer plug (2) through left outer race (4)
and into installer base (1). Press race into bore until
firmly seated against retaining ring (3).
5. Insert "SPORTSTER" end of installer base (1) into out-
board side of left crankcase half (6) bearing bore until
base contacts outboard surface of installed left outer
race (4).
6. Position right outer race (5) over bearing bore on inboard
side of left crankcase half (6).
7. Insert shaft of installer plug (2) through right outer race
(5) and into installer base (1). Press race into bore until
firmly seated against retaining ring (3).

sprocket shaft tapered roller bearings and seal.
8. See Figure 3-89. Place bearing cone (3), small end
upward, over end of sprocket shaft. Position spacer (2)
over sprocket shaft with (radius) rounded end downward.
Thread nut driver (1) on sprocket shaft. Turn nut driver
onto shaft until nut bottoms at end of threads. Remove
nut driver and spacer (2).
9. See Figure 3-88. Repeat procedure using spacers (3, 4,
5 and 6) until bearing cone bottoms against the shaft
shoulder.
10. See Figure 3-90. Position left crankcase over sprocket
shaft so that the shaft is through the bearing cups in the
bearing bore. Place the spacer that determines end play
(item 6 in Figure 3-68.) over sprocket shaft. Position left
bearing cone over end of shaft with small end downward.
Place spacer (2) over sprocket shaft with flat end down-
ward. Thread nut driver (1) on sprocket shaft. Turn nut
driver onto shaft until threads bottom. Remove nut driver
and spacer. See Figure 3-88.
