. Loosen rocker arm jam nut. Turn

pivot ball stud while checking clearance between
rocker arm and valve stem with a feeler gauge.

2.

See

Figure 1-11

. When clearance is correct, hold

pivot ball stud with Allen wrench and tighten rocker
arm jam nut to specified torque with a crow foot
wrench. After tightening jam nut, recheck valve
clearance to make sure it did not change.

Rocker Arm Jam Nut ft-lbs
4209 to 12

Install Rocker Arm Cover

1.

Use a new rocker arm cover gasket. Install rocker
arm cover and retain with four screws.

Results

Adjust valves to specification and test. If problem
continues, refer to flow chart.

Test 25 – Check Engine / Cylinder

Leak Down Test / Compression Test

General Theory

Most engine problems may be classified as one, or a
combination of the following:

•

Will not start

•

Starts hard

•

Lack power

•

Runs rough

•

Vibration

•

Overheating

•

High oil consumption

General Theory

The  Cylinder  Leak  Down  Tester  (Figure  44)  checks
sealing (compression) ability of engine by measuring air
leakage  from  combustion  chamber.  Compression  loss
can  present many different  symptoms. This test detects
the  section  of  the  engine  where  the  fault  lies  before
disassembling the engine.

Procedure

1.

Remove spark plug.

2.

Gain access to flywheel. Remove valve cover.

3.

Rotate engine crankshaft until the piston reaches
top dead center (TDC). Both valves should be
closed.

4.

Lock flywheel at top dead center.

5.

Attach cylinder leak down tester adapter to spark
plug hole.

6.

Connect an air source of at least 90 psi to the leak
down tester.

7.

Adjust regulated pressure on gauge to 80 psi.

8.

Read  right  hand  gauge  on  tester  for  cylinder
pressure.  20  percent  leakage  is  normally
acceptable.  Use  good  judgment, and  listen  for  air
escaping  at  carburetor,  exhaust,  and  crankcase
breather. This determines where the fault lies.

Figure 1-12. Spark Tester

Results

•

Air escapes at carburetor – check intake valve.

•

Air escapes through exhaust – check exhaust
valve.

•

Air escapes through breather – check piston rings.

•

Air escapes from cylinder head – replace head
gasket.
