Starter One-way Clutch Bearing
Following instructions on cleaning out starter solenoid and starter motor itself posted here on the forum. While doing that, I noticed that the starter spins in either direction, not one way as others have indicated.
I've been chasing down a cold start starting issues, typically requiring two turns of the key in the ignition to start the car. Could the failure of the one-way starter clutch mechanism be my issue? What would the symptoms of a failed one-way? Where can one purchase a replacement one-way clutch bearing? Any feedback would be greatly appreciated. Thanks!!!!! |

More info needed........
What year car are you working on? Explain your cold start issue further. Does anything happen on the first turn of the key? Does the motor turn over? Can you hear a click? The starter will only turn one way with power applied to the solenoid.

Wilson...yes you are correct...the one way "bearing" is part of the drive assembly.
Normally the gear (that engages the flywheel) and the "bearing" and a spring are all one piece on a starter. They are replaced as one piece. Bob

If the one way clutch doesn't function the starter will spin without turning the engine over. Should be pretty noticeable.

83sc. Car starts so that's where I'm confused. I'm thinking the one way is starting to fail. I notice sometimes when I'm cranking the rpms drop say 2-3 seconds during cranking. Anyways if the one way turns both ways that's a clear sign of an issue? Where would one get the replacement piece?

The assembly is called a Bendix for most cars.
Not sure if the name is the same for our babies...but should be...and any parts man will know what you are talking about. Bob

Check your cranking amps from the battery, check the absolute quality of the grounding (it is amazing how often these are involved) and last, bench test the starter with battery to make sure the shaft extends quickly, spins and retracts.
If there are problems with the starter, it is usually cheaper to get a re-built one. |
