——Remove the studs of same length .
Assembly:
——submerge the push rod into the engine oil or pour engine
oil into the rod’s hole of the cylinder head and install the push
rod into the hole. The gap between push rod and hole is
0.035-0.055mm.
——screw in the studs into the threaded hole and tighten with
the nuts.
——install fuel pump with the manufacturer mark and part
number forward.
——Tighten the lock nuts with hands. tightening torque is
14-18Nm.

1.3 Carburetor.

basic parameters:

Pierburg 2E3 carburetor:

CAC478

CAC480

Larger throat pipe diameter

20/24

22/26

Mixing chamber size

28/30

28/30

Installation:

Use studs, nuts, and washers to connect the transition

flange with intake manifold. Screw the studs into intake
manifold and tighten them with nuts. tightening torque is
8-10Nm.

Adjustment: The carburetor adjustment mentioned in this

introduction only specifies the idle speed adjustment and CO
adjustment . The other adjustment and service should be done
by professionals.

——Adjustment of Peirburg 2E3 carburetor:
Idle speed adjustment:

Rotating the screw inward will increase idle speed.

Rotating the screw outward will decrease idle speed.
CO adjustment:

Rotating the CO screw inward will enrich the mixture .

Rotating the screw outward will make the mixture lean.

by adjusting idle adjustment screw of the idle up

actuator valve, idle speed may be adjusted to the specified
valve under load .

2.1 Description for fuel system.

the fuel pump in the fuel tank supplies fuel, though fuel

filter, to the fuel injector in the throttle valve body. the redundant fuel returns
to the fuel tank . The vapor from the fuel tank goes into the charcoal canister
by fuel vapor pipe and is sucked into air intake pipe though the fuel vapor
recirculation solenoid valve which is controlled by ECU. For more detailed
information, See “CAC480M Engine’s single port injection system” .

2.2 for more details of the Fuel pump, fuel vapor recirculation
solenoid valve and charcoal canister, see “CAC480M Engine’s
single port injection system” section.

【18】 Engine electrical system.
The electrical system includes battery, alternator, starter, breakerless distributor, ignition controller, spark plug,
high-power ignition coil, high pressure assembly, water temperature sensor, oil pressure switch, electric fan,
thermo switch, and idle speed solenoid valve of carburetor.

1. Alternator.
Output voltage:

14V

Rated output current:

90A

B+Output D+ to the charging indicator filling-in bit

——battery is not permitted to be connected to alternator with the
polarities reversed.
——insure that the ground wire between the alternator and
chassis are tightly connected.
——it is forbidden to ground the power supply wire while the
alternator is under working condition, the wiring harness will be
burn away.

——while the alternator is under working condition, it is not
allowed to disconnect the alternator connector B from battery, or
the voltage caused will damage the transistor or other elements.
——To test the diodes, the voltage applied should be not beyond
40V.
——during servicing the alternator, apply enough No.2 lithium
base grease into the alternator sealing bearing for the operation
period before the next service.
——The electronic regulator needs no service and may only be
replaced if damaged.


——The alternator type is: JFZ1913—4 and JFZ1813—ZB.

——The alternator bracket for vehicle is quite different from the
one for independent assembly . The former is applied on the
engine equipped with A/C compressor.
——The left figure is the alternator bracket for the vehicle.
——the corresponding alternators are not exchangeable.

Starter.

Rated output:

0.95kW

Speed range:

1000-1800r/min

Voltage:

12V

Type:

QDY1258

SD6RA78

——the flywheel gear ring for vehicle and the one for
independent engine assembly are different and also the starter
gear modulus are different ,, so different starters need to be
applied..

——The

left

figure indicates SD6RA78.

——The

tightening torque for bolt installation is

40±4Nm.
