Valve Spring InspectionS7RS0B1406028
Valve Spring Free Length and Preload
Referring to data, check to be sure that each spring is in
sound condition, free of any evidence of breakage or
weakening. Remember, weakened valve springs can
cause chatter, not to mention possibility of reducing
power output due to gas leakage caused by decreased
seating pressure.
Valve spring free length
Standard: 39.37 mm (1.550 in.)
Limit: 36.49 mm (1.437 in.)
Valve spring preload
Standard: 161– 185 N (16.1 – 18.5 kg)
(35.4 – 40.7 lb / 1.240 in.)
Limit: 159 N (15.9 kg) for 31.50 mm (35.1 lb / 1.240 in.) Spring Squareness
Use a square and surface plate to check each spring for
squareness in terms of clearance between end of valve
spring and square. Valve springs found to exhibit a
larger clearance than limit must be replaced.
Valve spring squareness
Limit: 1.7 mm (0.067 in.)

Installation
NOTE
• Use new bearing cap No.1 bolts. They are deformed once they are used because they
are plastic deformation tightening bolts.
• All parts to be insta lled must be perfectly
clean.
• Be sure to oil crankshaft journals, journal bearings, thrust bearings, crankpins,
connecting rod bearings, pistons, piston
rings and cylinder bores.
• Journal bearings, bearing caps, connecting rods, rod bearings, rod bearing
caps, pistons and piston rings are in
combination sets. Do not disturb such
combination and make sure that each part
goes back to where it came from, when
installing.

1) Install sensor plate (1) to crankshaft (2) and tighten bolts to spec ified torque.
NOTE
When installing sensor plate, align spring pin
(3) on crankshaft and hole of sensor plate.

Tightening torque
Sensor plate bolt (a): 11 N·m (1.1 kgf-m, 8.0 lb-ft) 2) Install piston cooling valves and nozzles, if removed.
NOTE
Install piston cooling valve while matching
piston cooling nozzle (1) to positioning (3) of
cylinder block when installed piston cooling
valve (2).

Tightening torque
Piston cooling valve (a): 11 N·m (1.1 kgf-m, 8.0
lb-ft)
3) Install main bearings to cylinder block. Upper half of bearing (1), has an oil groove (2).
Install it to cylinder block (3), and the other half
without oil groove to bearing cap.
Make sure that two halves are painted in the same
color.
4) Confirm that dowel pins (3 ) are installed to intake
side of each journal.

Reassembly1) Wash, clean and then dry all disassembled parts.
2) Apply thin coat of engine oil to inner and outer rotors, oil seal lip portion, inside surfaces of oil pump case
and plate.
3) Install outer (1) and inner rotors (2) to oil pump case.
4) Apply engine oil to relief valve (1) and spring (2), and install them with retainer (3) and new circlip (4) to
rotor plate (5).
5) Install rotor plate and tighten all bolts to specified torque. After installing plate, check to be sure that
rotors turn smoothly by hand (0.3 N ⋅m (0.03 kgf-m,
0.25 lb-ft) torque or below).
