200 BENCH PROCEDURES
Assembly
Refer back to Figure 5-70.
1. Install oil pressure relief valve plunger (11) in
relief valve housing (4).
2. Install oil pressure relief valve spring (12) in
relief valve housing.
3. Clean oil pressure relief cap (13) and install
in relief valve housing.
To maintain correct oil pressure for various oil
system arrangements, the proper oil pressure
relief valve spring and cap combination must be
used. Using incorrect components may result in
either high or low oil pressure, and contribute to
premature engine damage.
4. Install oil pump inlet flange cover (9) and
gasket (8) on housing. Secure with
capscrews (10).
5. Install driving shaft and gear assembly (6) in
housing and check for free spin.
6. Install idler gear (14) on housing shaft.
It is extremely important that pump application be
checked prior to drive gear assembly. Several
drive gears are available to establish correct oil
pump-to-auxiliary drive gear ratio combination.
Failure to select proper drive gear for application
will result in gear and engine damage. Refer to
Improved “Fast Ratio” Auxiliary Driveshaft in this
section.
Apply Loctite
®
271 to all capscrews used to
assemble the oil pump.
7. Install cover (7) on pump and secure with
capscrews. Torque to 15 lb-ft (20 N•m).
8. Install key (5) in driving shaft and gear
assembly (6).
9. Place gear (3) on shaft aligning slot with key
on shaft. Press drive gear on shaft.
10. Install washer (2) and self-locking nut (1) on
shaft. Torque to 60 lb-ft (81 N•m) using
torque wrench J 24407 or equivalent.
11. Install pickup tube and screen assembly.
[221 CD] ECONOVANCE
Econovance Control Valve
Assembly
Refer to Figure 5-74.
The Econovance control valve assembly consists
of a valve housing (7) and a solenoid valve
assembly (6).
The valve housing (7) contains oil passages to
direct engine oil pressure to the Econovance,
enabling the Econovance to perform the function
of dynamically varying injection pump timing.
The solenoid valve assembly (6) consists of a
proportional solenoid controlled by the V-MAC
module, which can position the solenoid
anywhere within its range of travel; and a
hydraulic spool valve, the position of which
determines engine oil flow to the Econovance.
The spool valve is not affected by the oil pressure
it controls. The three O-rings on the spool valve
are replaceable.
