Before disassembling the starter, you need to check its serviceability with simple checks
Removing the starter as described in the previous article
Using a screwdriver, we check the ease of movement of the drive coupling along the shaft
We turn the gear of the drive. The gear should rotate easily relative to the clutch hub in the direction of rotation of the armature and should not rotate in the opposite direction
After that, we connect the "minus" terminal of the battery with the starter housing with wires
We connect the second wire with one end to the terminal plus of the battery, and the other to the output of the control wire of the traction relay
If the traction relay is working properly, then a click is heard and the drive clutch is extended. Otherwise, we replace the traction relay
Disconnect the wire from the control output of the traction relay and connect it to the lower contact bolt of the traction relay
The starter armature must rotate at a frequency of more than 6000 min-1. Otherwise, you need to repair the starter
Disassembly of the starter
Unscrew the nut of the lower contact bolt of the traction relay and disconnect the tire from the contact bolt of the traction relay
Unscrew the three screws securing the traction relay to the starter cover from the drive side
We remove the traction relay by disconnecting the anchor from the drive lever
We remove the anchor and the return spring from the body of the traction relay
Unscrew the tie bolts and disconnect the starter housing
Unscrew the two bolts and remove the bearing cover
Removing the brush assembly
We fix the brushes with a suitable sized head
Removing the rotor from the starter housing
Remove the rubber seal and remove the planetary gear
We pry with a screwdriver and remove the drive lever
We remove the limiting ring and disconnect the gear mechanism from the anchor shaft
Remove the restriction ring and cover
We remove the plastic gear from the shaft
Removing the gears from the guides
Squeeze and remove the locking ring
Removing the seal
Examining the brush holder
Check the height of the brushes in the brush holder. We check the insulated housings with an ohmmeter for a short circuit with the housing
There should be no damage on the slots and axles of the anchor shaft. The anchor collector must not have any traces of burning
Minor burning is eliminated with a rag soaked in gasoline and fine-grained sandpaper
We check the armature winding for a short circuit with an ohmmeter
Check whether the anchor of the starter traction relay moves easily, whether the contact bolts of the contact plate are closed (using an ohmmeter)
Checking the drive. The teeth of the drive gear must not have significant wear.
The gear should rotate easily relative to the clutch hub in the direction of rotation of the armature and should not rotate in the opposite direction
If the gear teeth are worn or damaged or the gear turns in both directions, replace the drive
There should be no cracks or signs of significant wear on the starter drive lever
Lubricate the spline surface of the armature shaft with silicon-containing grease
The drive coupling does not need to be lubricated and cannot be used for cleaning products that can wash the grease embedded in its coupling
Lubricate the bearings (bushings) in the starter covers with engine oil
We assemble the starter and all dismantled parts in reverse order
