- Form a bead of IVECO 2992692 sealant as shown in the

figure.

Figure 39

Installation of components for the application
Fitting the flywheel cover housing

- Carefully clean the contact sides between the crankcase

and the flywheel cover housing, removing any remains
of sealant with a scraper.

!

A perfect seal is only obtained by carefully cleaning
the surface to seal.

Smear the case with IVECO SEAL 2992692 to
obtain a bead of a few mm diameter.

It shall be uniform (no clots), without air bubbles, thin
areas or discontinuities.

Any imperfection shall be corrected as soon as
possible.

Avoid using excess material to seal the joint.

Excessive sealant could come out from joint sides
and cause lubricant passage clogging.

After applying the sealant, the joint shall be
assembled immediately (10—20 minutes).

NOTE Check the important measurements depending on

the application.

- Check the condition of the teeth for the ring gear (2).

If the teeth are broken or very worn, remove it from the
engine flywheel (1) using an ordinary drift and fit the new
ring gear, heated previously to a temperature of 150˚C
for 15’ P 20’; the bevel on the inner diameter of the ring
gear should be facing the engine flywheel.
