Thoroughly clean the crankcase / crankcase base mating
surface.
Apply, on base, sealant LOCTITE 510 IVECO no. 93162432,
as indicated in the scheme. The sealant must result to be
even, not patchy.
Mount the crankcase base (12) and tighten the fixing screws
in three stages, following the sequence shown in the figure:
- Step 1: with a torque wrench, to a torque of 50 Nm.
- Step 2: closing to an angle of 60
°.
- Step 3: closing to an angle of 60
°.
Then tighten the outer screws (1) to a torque of 36 — 30 Nm.
Carefully clean the seal seat. Apply LOCTITE 510 IVECO nr.
2992504 on the seal (1) for 30
° in the points shown in the
figure.
Lubricate the rear shank of the crankshaft with engine oil.
Fit part (2) of tool 99346255 onto the rear shank of the
crankshaft; secure it with the screws (3) and key the fresh seal
(1) onto it.
Position part (4) on part (2); screw down the nut (5) to fit
the seal (1) fully inside the crankcase.

Assembling rear seal
Mount the crankcase base within 10 minutes of
applying the sealant.
NOTE
Use tool 99395216 (11) for the angle closing.

Check clutch disk rest surface: if it shows deep scoring, a
replacement must be performed.
Mount the sheet metal guard (1) and secure it to the crankcase
tightening the screw (2) to the prescribed torque.
Mount the engine flywheel (3) and screw down the screws (4).
Fit tool 99360351 (4) onto the crankcase to block rotation
of the engine flywheel (1).
Tighten the screws (3) fixing the engine flywheel (1) in two
steps:
- Step 1: with a torque wrench, to a torque of 30 Nm.
- Step 2: closing to an angle of 90
°.

Replacing bearing supporting gear-
box input shaft
The bearing (2) supporting the gearbox input shaft is
removed and fitted using a general-purpose drift.
Check conditions of the teeth of crown wheel (1); where
excessive cracking or wear is found, replace engine flywheel.
The nominal thickness of the engine flywheel is 50
±0.6 mm.
NOTE
Use tool 99395216 (2) for the angle closing.

Remove the piston rings (1) from the piston (2) using pliers
99360183 (3).
Using a micrometer (2), measure the diameter of the piston
(1) to determine the assembly clearance. The diameter has
to be measured at the value shown.

By means of micrometer (2), measure the diameter of piston
(1) to determine mounting clearance; the diameter must be
detected at distance X from piston base:
-
46 mm - engine F1AE0481A (96 HP)
-
45.5 mm - engine F1AE0481B (116 HP).
The clearance between the piston and cylinder liner can also
be checked using a feeler gauge (1) as illustrated in the figure.

Conditions for correct pin-piston coupling
Lubricate the pin (1) and its seat on the hubs of the piston
(2) with engine oil. The pin must go into the piston by lightly
pressing with the fingers and must not drop out by gravity.

The trapezoidal split rings (1
st
slot) and the oil scraper rings
(2
nd
slot) have the word TOP etched in them; when fitting
them on the piston, the word TOP must be facing upwards.
