On a car with a Cummins ISF2.8 power plant, a 5295576 Dixie Auto Electric starter is installed
The starter is an electromagnetically excited DC motor.
The starter has four poles.
On top of the starter, there is a traction relay with two windings - a retractor and a holding one.
When the key is turned in the ignition switch to position "II", the power supply circuit of the traction relay windings is closed.
The relay armature is retracted and, through the lever, engages the starter gear with the engine flywheel ring gear.
At the end of the stroke, the armature turns on the starter power circuit and at the same time turns off the retractor winding of the relay (power is supplied only to the holding winding).
When the key is returned to the "I" position in the ignition switch, the power supply circuits of the starter and the holding winding are cut off, and under the action of the spring, the armature disengages the starter gear from the flywheel ring gear.
The rated power of the starter is 5295576 - 2.5 kW.
Removing the starter
You will need a wrench for 13 and a 12-point socket for 10
Disconnect the negative terminal of the battery necessarily!
Disconnect the control drive block from the traction relay
Remove the protective cap from the contact bolt of the traction relay and move the cap
Unscrew the nut securing the power wire tip
Remove the washer under it
We remove the tip of the power wire from the contact bolt of the traction relay
Unscrew the three starter mounting bolts
This is how the starter mounting bolts are located
We remove the starter. Install the starter in reverse order.
Possible starter malfunctions
- Cause of malfunction
Remedy
Starter does not turn on:
- Battery defective
Replace the battery
- Oxidation of the battery terminals
Strip and tighten the terminals and wires leading to the battery
- Faulty ignition lock
Replace the contact group or ignition switch
- Defective traction relay
Replace the traction relay
- Defective starter
Repair or replace starter
The traction relay switches on, but the starter rotor does not rotate or rotates too slowly:
- The battery is discharged
Charge or replace the battery
- Oxidation of battery terminals and wire lugs
Strip and secure the terminals and wires
- Loose tightening of the nuts securing the wire lugs on the traction relay terminals
Tighten the nuts
- Defective starter
Repair or replace starter
The traction relay switches on and off immediately (frequent knocking):
- The battery is heavily discharged
Charge or replace the battery
- Increased resistance of the starter power supply circuit
Strip and fasten the cable lugs, replace the faulty wires
- Faulty ignition lock
Replace the contact group of the ignition switch
- Defective traction relay
Replace the traction relay
Starter engages but crankshaft does not engage:
- nicks on the teeth of the drive gear or flywheel rim
Repair nicks or replace flywheel or starter drive
Starter engages but gear does not engage:
- nicks on the teeth of the drive gear or flywheel rim
Repair nicks or replace flywheel or starter drive
The starter does not turn on after starting the engine:
- Jammed key in the ignition switch in position "|"
Repair or replace the mechanical part of the ignition switch
- Closing the contacts of the ignition switch (lock)
Replace the ignition switch (lock)
- Defective starter
Repair or replace starter
Increased noise when the starter rotor rotates:
- Loose starter mount
Tighten the starter mounting bolts
