[213 JB] VALVE COVER
Description
Valve cover mounting capscrews have
undergone a manufacturing change. The existing
mounting capscrews require two different sockets
for cover installation. The new capscrews require
only one socket. Note the capscrews used on
your engine and replace with the same
capscrews, if required.
Cylinder head cover (No. 337GB494M2) used on
E7, CH 4 x 2 models with Jake Brake and air
conditioning, contacts the air-conditioning
expansion valve (mounted on the cab fire wall)
during articulation. To eliminate this engine/cab
interference condition, a new rear cylinder head
cover (No. 337GB4108M) is available.
The valve cover (and riser, if equipped with Jake
Brake, Figure 6-73) requires a strip-type seal
valve cover gasket, 51 inches (130 cm) in length.
Sealing compounds are not necessary.
Installation
Refer to Figure 6-71.
Installation procedures for riser and valve cover
seal are identical.
1. Install a seal strip (2) in the seal grooves (3)
of the risers.
a.
Thoroughly clean the gasket contact
surface.
b.
Install one end of riser gasket into seal
groove (inboard side) approximately
1/4 inch (6.4 mm) from the end of the
groove.
c.
Guide the seal strip into the groove
around the circumference of the riser.
Complete installation and overlap at the
starting point approximately 1/4 inch
(6.4 mm) from the end of the groove.
Figure 6-71 — Gasket Installation
Refer to Figure 6-72.
2. Position the riser (4) on the cylinder heads.
3. Connect the actuator wire to the actuator (3).
4. Install a seal strip in the valve cover seal
groove of the valve covers.
a.
Thoroughly clean the gasket contact
surface.
b.
Install one end of valve cover gasket
into seal groove (inboard side)
approximately 1/4 inch (6.4 mm) from
the end of the groove.
c.

around the circumference of the valve
cover. Complete installation and
overlap at the starting point
