Repair of the starter with your own hands should begin with the diagnosis of its malfunctions and checking the motor for operability. To begin with, it is necessary to disconnect the starter, then to disassemble it.
If the starter is OK, then when the thick outlets on the retracting relay close , it will work. In a situation where in this state the starter will work absolutely effortlessly, and in contact with the flywheel otherwise, it will be possible to draw a definite conclusion. If everything is as described, then the starter does not have enough power to start the engine.
Before buying a new starter, you should try to find and, if possible, troubleshoot the old starter. Its replacement is the easiest solution, but the need for this does not always exist.
Before you begin to check the malfunction of the starter, you must note the initial position of the pulling relay on it. During the assembly process, these labels can make your work easier. Repair of starters of foreign cars, which are not very new, usually takes place with the work on the starter faults associated with elementary pollution and deterioration of the lubricant. When the dismantling of the starter is done, it must be carefully examined. If there is a need, you will have to perform the following works: make a grinding of the collector, check the brushes, cleaning them as necessary, and also clean all the details from the past grease, which is already unusable, and make a new application. As the applied lubricant may come Solidolol or Lithol.
Further, if you undertook to determine the malfunction of the starter, you need to carefully inspect its front bushing. Very often it is because of the problems with this part that there is a need to replace the starter. This part is most often the first one that breaks down and signals the starter's malfunction. Therefore, starting the engine will simply not be possible. Of course, it will be possible to purchase a new starter, but, as they say, it will always succeed. Often the best option is simply to purchase a new bushing. You can also make it from a copper-graphite alloy or from bronze.
In the event that the starter's faults are related to the bendix, you must check it for dirt. More often it is pollution that interferes with its normal operation. In this case, try to boil it in engine oil. Sometimes this can help, and the bendix will work properly. If the digestion of the desired result does not give, then the starter change will become inevitable. There is only one way out: buying a new starter.
Sometimes the restoration of a bendix may help. True, this is possible only on the condition that you have enough time and you are well versed in the matter. For restoration, you should disassemble the bendix and replace all its rollers and springs. If it is possible to install a new housing, then it should also be produced. In the event that nothing happens, you can buy a new Bendix and replace it with an old one.
