4.

Remove crankshaft and shells.

5.

Position crankshaft in vertical fitted in the
flywheel in order to avoid warping.

Cleaning and inspection

1.

Remove remains of gasket from rear seal
housing and from engine block.

2.

Clean main journals and crankpins, checking
for risks and damages.

3.

With micrometer, measure main journals and
crankpins diameter and out of roundness in 4
places.

4.

Check crankshaft main journals maximum
eccentricity with dial indicator gauge. Main
journals nr. 1 and 5: Supported.

5.

Check for cracks with Magnaflux.
Demagnetize crankshaft in case of cracks,
the part must be replaced..

Machining and inspection

1.

Machine main journals and crankpins to the
immediately lower undersize than the
obtained measure. Check main journals
rugosity and fillets. Main journals/crankpins
rugosity, see TECHNICAL SPECIFICATIONS.

2.

Remove sharp chamfers from lubrication
holes.

3.

After the machining, wash crankshaft with
chemical solvent in immersion bathing. Dry
with compressed air.

7.

Check again crankshaft main journals
eccentricity.

8.

Check main journals and crankpins fillets
with caliper.

9.

To balance, remove material from crankshaft
arm sides. In case of part stock, apply
antioxidant oil immersion.

10. Before assembly, wash crankshaft with water

at 80 °C (176 °F) in agitation immersion
bathing and dry with air.

4.

Check for cracks and remove crankshaft
magnetization.

5.

Clean the lubrication holes.

6.

Check with micrometer main journals and
crankpins length, see TECHNICAL
SPECIFICATIONS - Crankshaft.

Assembly

1.

Clean shells housing on the block and
bearings caps. Check if engine block
lubrication galleries are not obstructed.

2.

Assembly upper and lower shells on engine
block and bearing caps, correctly positioning
locks.

3.

Lubricate upper shells and crankshaft main
journals and crankpins,

4.

Lubricate the two upper thrust washers,
positioning lubrication channels to crankshaft
and slip them in their block housing.

5.

Assembly crankshaft. Do not turn crankshaft
before bearing caps fixation.

6.

Lubricate lower shells.

7.

Assembly bearing caps correctly positioning
them.

8.

After 5th cap assembly, apply Loctite 5900 on
bearing side grooves.

9.

Fix bearings from the ends to the center and
tighten bolts according to specification.
Manually turn crankshaft after final tightening
of each bearing cap, see TIGHTENING
SPECIFICATIONS.

10. Check crankshaft axial clearance using a dial

indicator gauge. If clearance checked is over
than specified, replace thrust washers.

Rear seal

Assembly

1.

Carefully clean engine block surface and
crankshaft flange and remove all existent
residues.

2.

Apply a fillet of Loctite 5900 in all rear seal
housing edge.
