Regarding fixing an old starter:
It *might* be possible to fix an old starter, but it's generally not cost-effective or practical for most people. Starters are relatively inexpensive components, and the labor involved in disassembling, cleaning, and replacing worn parts (like brushes or the solenoid) often outweighs the cost of a new or remanufactured unit.
Here are the common problems with starters and whether they can be fixed:
* Worn Brushes: These are relatively easy to replace if you have some mechanical aptitude and the right tools. However, finding replacement brushes for an older starter can be tricky.
* Bad Solenoid: The solenoid is responsible for engaging the starter motor. Sometimes a simple cleaning of its contacts can fix intermittent problems. Replacing the solenoid is usually possible, but again, parts availability might be an issue.
* Internal Motor Issues: If the motor itself is burned out or has internal damage (e.g., shorted windings), it's generally not worth repairing. The cost of repair parts and the specialized tools needed usually exceed the cost of a replacement.
* Gear Stripping: If the starter gear that meshes with the flywheel is stripped, the starter needs replacement.
Recommendation: Unless you're experienced with automotive repair and have access to the necessary tools and parts, it's usually best to replace a faulty starter with a new or remanufactured one. You can often find these at auto parts stores or online retailers at a reasonable price. The time saved is usually worth the small cost increase compared to attempting a repair.
