See
. Using a colored marker, mark one of the
links (1) of the primary cam chain to identify the visible
side. Maintaining the original direction of rotation during
assembly may prolong service life.
NOTE
Use a piece of wire in retention hole (6) to keep cam chain

Be sure to follow manufacturer's instructions when using
propane
torches.
Failure
to
follow
manufacturer's
instructions can cause a fire, which could result in death
or serious injury. (00465c)
•
Avoid directing heat toward any fuel system com-
ponent. Extreme heat can cause fuel ignition/explosion
resulting in death or serious injury.
•
Avoid directing heat toward any electrical system
component.
NOTES
•
Only use approved methods for removing rear cam bolt.
Other methods of removal, such as the use of a large
3-70 2013 Softail Service: Engine
breaker bar, may result in damage to chain drive and other
components.
•
If necessary, soften LOCTITE by using heat from a small
propane torch. Apply flame evenly around bolt in a circular
motion, but do not allow bolt to turn blue.
4.

Determine the required distance from the top of the support
plate to the edge of the installed needle bearing by adding
support plate thickness to 3.10 in. (78.7 mm). Record this
value.
NOTE
For example, if the support plate is 0.50 in. (12.7 mm) thick,
then the measurement from the top of the support plate to the
edge of the needle bearing should be 3.60 in. (91.4 mm).

11. See
. Once the bearing is at correct depth,
measure from head (top) of installer forcing screw to sup-
port plate. Record this measurement.
12. Remove forcing screw from support plate and install over
second needle bearing bore. Place installer at end of for-
cing screw. Place
new

on the chain, rotate the rear cam sprocket clockwise
until the flat on the crankshaft sprocket is aligned with
the flat on the crankshaft. Install the crankshaft
sprocket.
10. Rotate the crankshaft clockwise until the timing marks on
the sprockets are aligned and also aligned with alignment
mark (5) on cam support plate.
NOTES
•
Both crank and rear cam sprocket flange bolts are specially
hardened and the flat washers are of a special diameter.
•
Use only genuine Harley-Davidson parts when replace-
ment is necessary.
•
If new flange bolts are not available, thoroughly clean both
internal and external threads.
•

CLEANING AND INSPECTION
1.
Clean all parts in a non-volatile cleaning solution or
solvent.
Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)
2.
Dry parts using low pressure compressed air. Verify that
all oil passages are clean and open.
3.
Inspect for scoring, gouging or cracking caused by foreign
material.
4.
Inspect for grooves or scratches on the cam support plate.
5.
Check for excessive wear or damage on lobes of outer
and inner gerotor gears.
6.
See
. Check gerotor wear.
a.
Mesh pieces of one gerotor set together.
b.
Use a feeler gauge to determine clearance between
tips of lobes on inner and outer gerotors.
c.
Replace gerotors as a set if clearance exceeds 0.004
in. (0.10 mm). Inspect second gerotor set in the same
manner.
7.
Measure and compare thickness of each rotor in both
gerotor sets. Replace the gerotor set if the difference
exceeds 0.001 in. (0.025 mm).
3-82 2013 Softail Service: Engine
8.
See
. Assemble the oil pump.
9.
Verify feed gerotors extend past the oil pump surface
0.015-0.025 in. (0.38-0.64 mm).
10. If measurement is less than 0.015 in. (0.38 mm), remove
feed gerotor set and reassemble using
new
wave washer.
11. Repeat measurement and replace oil pump body if not
within specification.

CLEANING AND INSPECTION
1.
Scrape old gasket material from the crankcase flanges.
Old gasket material left on mating surfaces will cause
leaks.
2.
Clean all parts in a non-volatile cleaning solution or
solvent.
Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)
3.
Dry parts with moisture free compressed air.
4.
Verify that all oil holes and passageways are clean and
open.
5.
Check ring dowels for looseness, wear or damage.
Replace as necessary.
6.
Use a file to carefully remove any nicks or burrs from
machined surfaces.
7.
Clean out tapped holes and clean up damaged threads.
8.
Check the top of the crankcase for flatness with a
straightedge and feeler gauge. Replace if warped.
