Crankshaft End Play Inspection (2000-2002 Models)

NOTE

The 2003 models are equipped with an as-
sembled roller bearing and this procedure is
not necessary.

The crankshaft end play

must

be between 0.001-0.005

in. (0.025-0.127 mm). End play is determined by the
thickness of the shim between the inner and outer bearings
on the left side. Table 6 lists the shim part numbers and
thickness.

If the end play was measured before disassembly and

was within specification, and if the same components are
reinstalled, then the same size shim can be reinstalled as a
starting point.

Carefully measure the end play as described in Step 11.

If there is

any

doubt about your abilities to properly set up

the crankshaft end play, refer this procedure to a
Harley-Davidson dealership.

Tools

The following tools or their equivalents are required to

assemble the crankcase halves:
1. Sprocket shaft bearing installation tool (JIMS part No.
97225-55).
2. Crankshaft guide (JIMS part No. 1288).
3. Engine base stand (JIMS part No. 1138) and engine
stand (JIMS part No. 1142).

Procedure

1. Position the crankshaft (Figure 364) with the left side
facing up.
2. Apply clean engine oil or assembly lube to the inner
bearing and to the left side crankcase inner bearing race.
3. Install the shim of the specified thickness onto the inner
bearing inner race.
4. Place the left crankcase half over the crankshaft
sprocket and onto the inner bearing.
5. Make sure the connecting rods are positioned within
the crankcase openings (Figure 365).
6. Make sure the crankcase is located correctly on the
crankshaft inner bearing.

28. Install the lower chain guide (C, Figure 392) into
place and snap the two retention tabs (D) into place lock-
ing the guide in place.

29. Install and clamp the tensioner compressor (A, Fig-
ure 393) over the balancer chain adjacent to the hydraulic
tensioner and the bottom of the chain guide bracket.

30. Pump the tensioner compressor handle and compress
the hydraulic tensioner (C, Figure 393).
31. Slide the hydraulic tensioner retainer (B, Figure 393)
away from the tip of the tensioner (C).
32. Slowly release pressure on the tensioner compressor
and remove it.

CAUTION

After removing the balancer shaft retaining
pins, inspect the tip of each pin. If the small
ball at the end is missing, locate it within the
crankcase half and remove it. If the ball
worked loose and stays within the crank-
case, severe engine damage could occur.

33. Repeat Steps 29-32 for the remaining tensioner.
34. Slowly remove the balancer shaft retaining pin (D,
Figure 393), installed in Step 13, from the balancer shaft
support and the balancer.
35. Install a

new

rubber interconnect (Figure 384).

Front Sprocket Alignment

The balancer sprocket alignment tool (JIMS part No.

1166 or part No. HD-44064) is required for this procedure
(Figure 394).

This procedure if for the front sprocket only. The rear

sprocket is not equipped with a spacer.
1. Slide the special tool (Figure 395) over the crankshaft
and the timing sprocket shoulder.
2. Hold down the special tool in place on the crankshaft
and move the tool over onto the

front

sprocket face.

3. Alignment is correct if the tool’s

outside step

clears the

top surface of the sprocket (Figure 396). Alignment clear-
ance between the tool and the sprocket surface is 0.014 in.
(0.356 mm). The tool’s inside step

must not

pass over the

sprocket face.
4. If alignment is incorrect, replace the spacer with a new
one that will bring the front sprocket alignment into speci-
fication. Refer to Table 7.

Inspection

1. Clean all parts in solvent and dry with compressed air.
2. Check the flatness of each sprocket with a straightedge
and flat feeler gauge. The sprocket must be flat within the
service limit specification in Table 2.
3. Inspect the crankshaft and balancer sprockets for un-
dercut or sharp teeth (Figure 397) or missing teeth.

NOTE

The balancer chain sprocket on the crank-
shaft is pressed into place. If severely dam-

aged, have the sprocket replaced by a
Harley-Davidson dealership.

4. If excessive wear or damage is evident, replace the bal-
ancer sprockets and balancer chain as a set. Rapid bal-
ancer chain wear occurs if the new chain is installed with
worn sprockets.
5. Check the sprocket surface where it mates with the bal-
ancer surface. Make sure the surface is clean without any
burrs or surface irregularities. Replace as necessary.
6. The balancer chain will darken to a brown color as the
result of wear and the exposure of engine oil. If the chain
has turned blue, it has overheated and should be replaced.
7. Inspect the inner plate chain links. They must be
slightly polished on both sides. If the chain shows consid-
erable uneven wear on one side, the sprockets are cor-
rectly aligned. Excessive wear requires the balancer chain
and sprockets to be replaced.
8. Inspect the upper and lower chain guides for wear or
damage. Replace any guide if a groove is worn to the wear
limit in Table 2.
9. Inspect the chain guide support assembly for wear or
distortion. Replace if necessary.

Balance Shaft Bearing Inspection/Replacement

Inspection

Refer to Figure 388.
Inspect the balancer bearing in the balance shaft support

and in the left side crankcase (Figure 398). Turn each in-
ner race by hand (Figure 399). The bearing must turn
smoothly. Some axial play is normal, but radial play must
be negligible. See Figure 400.

If the bearing(s) is damaged, replace it as described in

the following.

Inner crankcase bearing replacement

A balancer shaft bearing remover and installer (JIMS

part No. 1167) and a hydraulic press are required to ser-
vice the counterbalancer shaft bearing.
1. Separate the crankcase and remove the balancer sys-
tem as described in this chapter.
2. Thoroughly clean the crankcase half with solvent and
dry with compressed air.
3. Place the left side crankcase half on towels or shop
cloths to protect the exterior finish. Place the crankcase on
the workbench.
4. Apply a light coat of graphite lubricant to the threads
of the bearing puller and large nut.
