OIL PRESSURE

OPERATION

All Models

When an engine is cold, the engine oil is more viscous (thicker).
During start-up, oil pressure will be higher than normal and oil
circulation will be somewhat restricted. As the engine warms
to normal operating temperature, the engine oil warms up and
becomes less viscous. The oil pressure decreases.

•

Increased engine speed results in higher oil pressure. The
faster the oil pump rotors spin, the greater the volume of
circulated oil.

•

Decreased engine speed lowers the volume of oil pumped
and the measured oil pressure.

XL Models

The oil pump is non regulatory and delivers its entire volume
of oil under pressure to the oil filter mount.

XR 1200X

The feed oil pump incorporates a bypass valve that will open
at approximately 50 psi (345 kPa), preventing overpressure in
the oil cooler and related components. The XR 1200X incorpor-
ates a thermostat in the oil cooler return path.

Oil Pressure Indicator Lamp

See

Figure 3-1

. The oil pressure indicator lamp turns on to

indicate improper circulation of the engine oil.

Refer to

Table 3-20

. The oil pressure indicator lamp turns on

when:

•

Ignition switch is turned on prior to starting engine.

•

Oil is not circulating through the running engine.

•

Oil pressure is abnormally low on the running engine.

•

Engine is idling far below 1000 rpm.

The oil pressure indicator lamp turns off when oil is circulating
with adequate pressure through the engine running at 1000
rpm or greater.

sm02321

Figure 3-1. Oil Pressure Indicator Lamp

If the oil pressure indicator lamp remains lit, always check
the oil supply first. If the oil supply is normal and the lamp
is still lit, stop the engine at once and do not ride further
until the trouble is located and the necessary repairs are
made. Failure to do so may result in engine damage.
(00157a)

NOTE

Residual oil pressure in the filter housing will sometimes pre-
vent the lamp from turning on. This may occur when cycling
the ignition key to on after stopping the engine.

CRANKCASE BREATHING SYSTEM

XL MODELS

See

Figure 3-6

. On the piston downstroke, a mixture of crank-

case air and oil mist is vented up the pushrod covers (1)
through a breather valve (2) in each inner rocker box section.

The oil mist separates from the crankcase air, collects and
passes through a small drain hole adjacent to the exhaust valve
in the head where it eventually returns to the crankcase.

The crankcase air is routed through a passage in each cylinder
head. The crankcase air then travels through each air cleaner
backing plate mounting bolt (3) into the filtered side of the air
cleaner.

2. Breather valve
3. Air cleaner backing plate bolt

Figure 3-6. Crankcase Breathing System: XL Models

XR 1200X

See

Figure 3-7

. During the piston downstroke, internal crank-

case pressure increases. Crankcase air/oil mist (9) is forced
into the area around the rocker arms and valve springs. The
vapor travels through two passages (6) in the inner rocker
cover. Then into a cavity (7) between the cylinder head and
inner rocker cover. The vapor then moves into the filter media
(8) of the breather valve (3).

The oil-laden vapor passes through the filter media (8) of the
breather valve assembly. The oil separates from the crankcase
air and drains back into cavity (7). There it flows toward the

exhaust valve. The oil then passes through a small drain hole
adjacent to the exhaust valve and returns to the crankcase.

Air pressure forces the breather umbrella valve (5) to open.
Air flows through a fitting (4) in the outer rocker cover. The
umbrella valve prevents the air from moving back into the
crankcase during piston upstroke. Air travels through a vapor
hose (2) connected to a hose and tee assembly (10) in the air
box. The air eventually exits into the intake air stream above
the induction module. The air is consumed by the engine.

TROUBLESHOOTING

DIAGNOSING VALVE TRAIN NOISE

To diagnose and correct noisy hydraulic lifters and valve train
components, use the following procedures:

With engine and oil at normal operating temperature, check
oil pressure at 2000 rpm. If oil pressure is above 50 psi
(345 kPa) or below 5 psi (34 kPa), inspect oil pump,
crankcase passages and oil hoses. Repair or replace parts
as necessary.

If oil is reaching the hydraulic lifters, remove and inspect.
Clean lifter bore of all foreign material. Replace parts as
necessary. See

3.22 BOTTOM END OVERHAUL:

ASSEMBLY, Tappets

Examine pushrod, lifter and lifter bore for proper fit and
any signs of unusual wear. Replace parts as necessary.

Visually inspect camshaft lobes for abnormal wear.

Remove camshafts and pinion gear, clean and inspect for
wear and fit. Replace parts as necessary.

Remove cylinder head and rocker box assemblies. Check
rocker arm end play and check for binding. Inspect valve
stems for scuffing and check stem to guide clearance.
Check valve seats for signs of looseness or shifting.

Face valves and valve seats.

COMPRESSION TEST

TOOL NAME

PART NUMBER

CYLINDER COMPRESSION GAUGE

HD-33223-1

Combustion chamber leakage may cause performance issues.
A compression test can help determine the source of cylinder
leakage.

Test engine at normal operating temperature

Disconnect spark plug wires.

Clean around spark plug base. Remove spark plugs.

Connect CYLINDER COMPRESSION GAUGE (Part
No. HD-33223-1) to front cylinder.

Make sure transmission is in neutral. With throttle plate in
wide open position, crank engine continuously through 5-
7 full compression strokes.

Note gauge readings at the end of the first and last com-
pression strokes. Record test results.

Connect the gauge to the rear cylinder and repeat test.

Compression is normal if final readings are within
specification and do not indicate more than a 10 psi
(0.689 bar) variance between cylinders. Refer to

Table 3-22

Compression is below specification if the readings
are 100 psi (6.89 bar) for 883 cc engines or 150 psi
(10.3 bar) for 1200 cc engines. Refer to

Table 3-23

Inject approximately 1/2 oz (15 mL) SAE 30 engine oil into
each cylinder and repeat the compression tests on both
cylinders. Readings that are considerably higher during
the second test indicate worn piston rings.

NOTE

Verify throttle plate is in the closed position after testing.

CYLINDER LEAKAGE TEST

TOOL NAME

PART NUMBER

CYLINDER LEAKDOWN TESTER

HD-35667-A

The cylinder leakage test pinpoints engine problems including
leaking valves, worn, damaged or stuck piston rings and blown
head gaskets.

Use CYLINDER LEAKDOWN TESTER (Part No. HD-35667-
A). Follow the specific instructions supplied with the tester.

Run engine until it reaches normal operating temperature.

Clean around spark plug base. Remove spark plugs.

Remove the air cleaner and set the throttle in the wide
open position.

Rotate the piston to TDC of the compression stroke (both
valves closed).

To keep the crankshaft from turning when air pressure is
applied to the cylinder, engage transmission in fifth gear
and lock the rear brake.

NOTE

Before performing the cylinder leakage test, verify that the
tester itself is free from leakage. Apply a soap solution around
the tester fittings. Connect the cylinder leakdown tester to the
compressed air source. Look for any bubbles that would
indicate leakage from the tester.

HOME

3-14 2013 Sportster Service: Engine

Following the manufacturer's instructions, perform a cyl-
inder leakage test. Make a note of the percent of leakage.
Leakage greater than 12 percent indicates internal engine
problems.

Listen for air leaks at induction module intake, exhaust
pipe and head gasket.

Air escaping through the induction module indicates
a leaking intake valve.

Air escaping through the exhaust pipe indicates a
leaking exhaust valve.

NOTES

•

If air is escaping through valves, check pushrod length.

•

Complete the cylinder leakage test(s). Install the spark
plugs. Verify that the throttle plate is in the closed position
before starting the engine.

DIAGNOSING SMOKING ENGINE OR HIGH

Gasket surface of both head and cylinder.

Cylinder head casting's porosity allowing oil to drain into
combustion chamber.

O-ring damaged or missing from oil pump/crankcase
junction.

ADJUSTMENT AND TESTING

General

Often only cylinder head and cylinder repair is needed (valves,
rings, piston, etc.). Service these components with the engine
in the frame. See

3.13 TOP END OVERHAUL: DISASSEMBLY,

Stripping Motorcycle for Top End Repair

After disassembling the top end only, it may be found that
crankcase repair is necessary. Crankcase repair requires
removal

engine

crankcase

from

chassis.

See

3.10 REMOVING ENGINE FROM CHASSIS

NOTE

Do not lay engine on primary side. Laying engine on primary
side will damage the clutch cable end fitting. If fitting is dam-
aged, replace the clutch cable.

Symptoms indicating a need for engine repair are often mis-
leading. If more than one symptom is present, possible causes
can be narrowed down to make a partial diagnosis. An above-
normal consumption of oil, for example, could be caused by
several mechanical faults. However, when accompanied by
blue-gray exhaust smoke and low engine compression, it
indicates worn piston rings. Low compression by itself however,
may indicate leaking valves, in addition to worn piston rings.
See

1.28 TROUBLESHOOTING

Piston slap is a condition where piston and/or cylinder are worn
out-of-round and are loose fitting, allowing the piston to slap
from front to rear of the cylinder as it moves up and down.

Frequently, valves, rings, pins, bushings and bearings need
attention at the same time. If any one of the above components
is worn, inspect all of these components. Repair or replace as
necessary.

ENGINE LUBRICATION SYSTEM

OIL PUMP OPERATION

The oil pump consists of two gerotor gear sets housed in one
pump body. One is feed and the other scavenge (return). Each
gerotor gear set has an inner and an outer gerotor. The inner
gerotor has one less lobe than the outer gerotor. Both gerotors
have fixed centers which are offset to each other. The inlet and
outlet sides of the pump are sealed by the tips and lobes of
the gerotor set. This prevents oil on the outlet side (high pres-
sure) from being transferred to the inlet side.

The feed pump distributes oil to the engine and has fewer lobes
than the scavenge pump, allowing for greater pressure devel-
opment. The scavenge pump returns oil to the tank and has
more lobes than the feed pump allowing for greater oil flow.

XL Models:

See

Figure 3-8

. Both rotor sets (3, 4) are driven

off a common shaft (2) that is coupled by gears to the crank-
shaft.

XR 1200X:

See

Figure 3-9

. The feed rotor set (4) is driven by

flats on the front intake camshaft (3). The scavenge rotor set
(5) is driven by flats on the rear exhaust camshaft (2).

CONNECTING FUEL HOSE AND FILLING
FUEL TANK

To prevent spray of fuel, be sure quick-connect fittings
are properly mated. Gasoline is extremely flammable and
highly explosive, which could result in death or serious
injury. (00268a)

See

Figure 4-7

. Connect fuel hose.

Push up on release sleeve (1).

Push fuel hose fitting (2) into fuel pump module fuel
pump quick-connect fitting.

Pull down on release sleeve to lock quick-connect
fitting.

Tug on fuel hose fitting to make sure it is securely
locked in place.

See

Figure 4-8

. Install vent hose onto vent nipple on fuel

tank.

Use care when refueling. Pressurized air in fuel tank can
force gasoline to escape through filler tube. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00029a)

Avoid spills. Slowly remove filler cap. Do not fill above
bottom of filler neck insert, leaving air space for fuel
expansion. Secure filler cap after refueling. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00028a)

Fill fuel tank and carefully inspect for leaks around fuel
pump module.

Install main fuse.

Turn ignition switch ON and verify fuel pump is activated.
Carefully inspect for leaks at quick-connect fitting. Turn
ignition switch OFF.

After installing seat, pull upward on seat to be sure it is
locked in position. While riding, a loose seat can shift
causing loss of control, which could result in death or
serious injury. (00070b)

Install seat.

VAPOR VALVE

Excessive pressure can build in the fuel tank if vapor valve
is not mounted vertically with long fitting to top. Leaks
due to excessive pressure can cause a fire or explosion,
which could result in death or serious injury. (00265a)

See

Figure 4-11

. The fuel tank is vented through a standpipe

(vent tube) within the tank. A hose (1) at the base of the fuel
tank is connected to the standpipe.

Keep vent and vapor valve lines away from exhaust and
engine. Gasoline is extremely flammable and highly
explosive, which could result in death or serious injury.
