AUXILIARY SHAFT AND
CAMSHAFT BENCH
PROCEDURES
Auxiliary Shaft Inspection
[212 CV]
The E-Tech™ auxiliary shaft is identified by three
painted stripes (early production) or three
machined circumferential cuts (later production)
in front of the stamped part number.
INSPECTION
Refer to Figure 160.
1. Thoroughly clean the auxiliary shaft.
2. Inspect the auxiliary shaft journals and
splines, and gear teeth and splines for
evidence of cracks, pitting, scoring or severe
wear. If any of these conditions exist,
replace the auxiliary shaft.
3. Make sure the orificed cup plug is in place in
the internal passage at the front of the
auxiliary shaft.

Camshaft Inspection

GENERAL INSTRUCTIONS
To optimize camshaft timing for certain engine
models, an offset-type camshaft key
(P/N 54GC29) is used. The offset key is color-
coded (with one end of the key painted white and
the other end painted red) and is installed with
the offset either to the right (cam timing retarded)
or to the left (cam timing advanced). Correct
camshaft key offset installation is dependent
upon engine horsepower ratings.
Some late-production high-horsepower engines
use the offset key, P/N 54GC31.
Make sure that the correct camshaft key and
positioning is used for the applicable engine
model. Engine timing will be adversely affected if
the incorrect key or positioning is used. When
utilizing the offset key, it must be installed with the
proper color facing front as follows:
r Straight Key P/N 43AX9 — Used with
EM7-300 (1750 rpm), E7-310/330,
E7-330/350, E7-355/380, E7-350
(1800 rpm), E7-400 (1800 rpm), E7-454
r Red Offset Key P/N 54GC29 — Used with
RED facing front for EM7-275 (1750 rpm)
and E7-300 (1700/1800/1950 rpm) effective
January 1998 with engine serial number
series 8A. Also used with RED facing front
for EM7-300 (1750 rpm) and E7-310/330
effective December 8, 1999 with engine
serial number 9Y0870 and implementation
of Step 7 software.
r White Offset Key P/N 54GC29 — Used
with WHITE facing front for E7-427 (effective
June 1997, with engine serial number
7M1305) and E7-460 (effective June 1997,
with engine serial number 7M3166).
Prior to the offset key tie-ins to the engine serial
numbers listed above, all engine models used the
straight key.
