Why does the starter spin but not turn the engine?
If the large gear is spinning, removing the motor was a coincidence. Unless, somehow, the starter motor is running backwards. That could only happen if you reversed the brush connections after you cleaned them. Looking at the gears, does the large gear spin clockwise when the starter runs?
Which is the bigger gear in the starter?
The bigger gear should be the input side of the starter clutch, and engages the rotor through the half of the clutch mounted to the back side of the rotor.
How does the starter turn on a motorcycle?
The starter fits into the first gear, which drives a second gear, called the idler. That idler gear turns the clutch gear. That means the direction reverses twice, so the starter should turn counter-clockwise as you look at the output end, same as the engine.
What should I do if my car starter is not working?
The cost on a starter not working can vary from no charge to many hundreds of dollars so it is important to get a clear idea of what’s wrong. For example a loose battery cable costs nothing to tighten, just a wrench and some elbow grease.
Why is my starter not engaging the flywheel?
Tighten the mounting bolts and other connecting wires. If the mounting bolt is loose, the starter drive will not engage the flywheel properly. It will make a grinding noise when you try to fire up your engine. What this means is that the pinion gear on the starter is clashing with the ring gear on the flywheel. Check the pinion gear.
What should I do if my starter is not working?
The starter pinion gear engages this wheel to make your car engine crank. Remove the starter motor and set your transmission gear to neutral. Rotate the crankshaft manually using a ratchet. There is a pulley at the front or bottom of your engine block. The pulley should move as you watch how the pion gears are reacting.
Where is the pinion gear on a car starter?

It starts the internal combustion of your engine. When the battery powers up after an ignition, electric current goes to the starter motor. In the starter motor, pinions move the engine.
The starter pinion gear engages this wheel to make your car engine crank. Remove the starter motor and set your transmission gear to neutral. Rotate the crankshaft manually using a ratchet. There is a pulley at the front or bottom of your engine block. The pulley should move as you watch how the pion gears are reacting.
Why is my starter spinning but not engaging flywheel?
The mechanism to engage the flywheel is faulty, probably it is seized, or battery doesn’t have enough power to make the solenoid fully pull the mechanism (check battery charge). Hit the solenoid “moderately” with a mechanic hammer, one or two dry blows, if next crank try works, then the mechanism is getting seized and needs maintenance.
Why does my iboats starter not go up properly?
If the starter does not spin fast enough it will not go up properly. Yes a bad solenoid can cause this problem. Over time the contacts in it gets burnt and does not supply the current needed for the starter. The lugs on the battery cables can get corroded inside where you can’t see it and cause that problem.
