CAUTION
Exhaust valve bridges must rest on ends of exhaust valves when tightening rocker arm
shaft bolts or damage to exhaust valves will result.
13.
Position rocker arms (Figure 4, Item 4) over cylinder compression adapter (Figure 4, Item 21) and exhaust
valves. Install two rocker arm shaft bolts (Figure 4, Item 3) and torque to 50–55 lb-ft (68–75 N·m).
NOTE
Do not crank engine using starter motor to obtain compression pressure. Engine
must be running to obtain accurate reading.
Variation in compression pressures between cylinders must not exceed 25 psi
(172 kPa) at 600 rpm.
Use spare fabricated fuel tube assembly to fabricate a jumper connection between
fuel inlet and fuel return manifold connectors. Do not install fuel tubes on engine
after bending for fabrication.
14.
Install spare fabricated fuel tube assembly (Figure 4, Item 23) between inlet manifold (Figure 4, Item 25) and
return manifold (Figure 4, Item 24).
WARNING
Avoid contact with hot manifolds, pulleys, and other moving parts. Wear proper ear
protection when running engine. Failure to comply may result in injury to personnel.
15.
Start engine and run at 600 rpm. Record pressure shown on fuel pressure gage.
16.
Stop engine. Move speed control lever (Figure 1, Item 5) to NO FUEL position.
17.
Cylinder compression pressure of any one cylinder, measured in Step 15 above, must not be less than
minimum pressures, see Table 1.

Remove spare fabricated fuel tube assembly (Figure 4, Item 23). Remove two rocker arm shaft bolts
(Figure 4, Item 3) and swing rocker arms (Figure 4, Item 4) away from cylinder compression adapter
(Figure 4, Item 21) and valves.
