9. Using a suitable press cup, press the gear
onto the shaft until it is fully seated. The
pressure gauge on the press should read
approximately 5 tons (4.54 MT) as the gear
is being pressed on. As the gear seats, allow
the pressure to climb to, but not exceed,
10 tons (9.1 MT). This will ensure that gear
is seated firmly on shaft.
10. When gear is properly seated, clearance
between rear face of gear and thrust washer
should be between 0.003–0.012 inch
(0.076–0.305 mm).
11. Thoroughly clean and degrease injection
pump driving gear with a suitable contact
cleaner that dries rapidly and leaves no
residue.
12. Prepare the gear bore surface with
Locquic™ Primer T, or equivalent.
13. Apply a bead of Loctite 609, or equivalent, to
the gear bore.
14. Using a clean brush, spread Loctite 609
evenly on the entire surface of the gear
bore.
15. Position gear onto camshaft.
16. Using a suitable press cup, press the gear
onto the shaft until it is fully seated. The
pressure gauge on the press should read
approximately 5 tons (4.54 MT) as the gear
is being pressed on. As the gear seats, allow
the pressure to climb to, but not exceed,
10 tons (9.1 MT). This will ensure that gear
is seated firmly on shaft. The gear should be
flush with the end of the shaft when fully
seated.

[213 EV] CYLINDER HEADS
Description
Refer to Figure 5-23.
The cylinder heads featured on 1991 and later E7
engines incorporate internal design modifications
that increase the swirl level of combustion air. To
achieve the increase in air motion required, it was
necessary to redesign the inlet port. Increased air
motion, in conjunction with the eight-hole Valve
Covering Orifice (VCO) nozzle tips, provides
proper air/fuel atomization in the deeper bowl of
the piston crown.
1991 and later E7 cylinder heads are NOT
interchangeable with 1989/1990 E7 cylinder
heads.
