6C – 6 FUEL SYSTEM
INJECTION PUMP



RTW 46CLF000201

4JA1T(L):
A Bosch Distributor Type Injection Pump is used. A single reciprocating/revolving plunger delivers the fuel uniformly
to the injection nozzles, regardless of the number of cylinders.
The governor, the injection timer, and the feed pump are all contained in the injection pump housing. The injection
pump is compact, light weight, and provides reliable high-speed operation.
The vacuum-type fast idle actuator increases the engine idling speed to provide the additional power required to
operate the air conditioner.
Fast idler diaphragm movement is caused by changes in the negative pressure created by the engine’s vacuum
pump.
The diaphragm motion is transferred to the injection pump control lever to increase or decrease the idling speed.

4JA1TC/4JH1TC:
The Bosch VP44 injection pump is electronically controlled. The pump controller combine to injection pump.
Signals from the pump controller are sent to the engine control module (ECM). In response to these signals, the
ECM selects the optimum fuel injection timing and volume for the existing driving conditions.

4. Heat a new con-rod to 280
°C in the oil bath.
5. Install the con-rod to the piston and insert the piston pin.


Important!
Since the con-rods have no weight balancing studs, re-working
is not possible.
Exchange con-rods in sets only.
Installation position, beads on con-rod point to the flattening on
the piston pin eye.
Firmly seated piston pin cannot be pushed in. Carry out
installation quickly.








Piston Rings
Removal
1. Remove piston with con-rod according to the corresponding operation.
2. Remove piston rings using commercially available ring installer or piston ring clamp pliers.

Clean
Piston ring grooves - ground piece of old piston ring


Inspection
Piston ring gap
