Sent to Car Experts February 17 07:50 PM

I have a new starter in my 1991 Land Rover Classic. The new starter, afer one month of use, is now not operating (tests reveal it is has failed). Several times I had noticed a mechanical noise under the hood after I shut the engine off . I now believe it was the starter continuing to turn, but not crank after the ignition key was turned off. I assume the starter got hot from turning and could be the cause of failure. What would cause this to happen? If this sounds too unlikely, what else would cause a starter to fail in such a short time?


Optional Information:
1991 Land Rover Classic 3.9 ltr V8

Already Tried:
All I have done is replace one faulty starter with another, and now that is dead. Wiring looks good as do solenoid, and regulator. Belize mechanic thinks it is being caused by under sized battery. Battery has always provided enough power. It too has just died along with the starter, however. The only thing that my non-mechanical mind can imagine is possibly the ignition switch could cause the starter to continue turning after the key is turned off. The engine cuts off, however, so I am at a loss. This vehicle is in Belize so hard, true answers are hard to come by. I need help.

You indicated that the bendix might be binding in the flywheel which continues to turn the starter. That would explain two starters in one month going TU. However, what would be causing this, how could I check to see if that is the problem, and more importantly what can I do to stop it from reoccuring?

I have seen two conditions that caused this.

1. There is some kind of defect with the Bendix assembly and the return springs don't pull it back when power is removed from the starter.

2. The started is binding when installed and not allowing the Bendix to disengage from the flywheel. This condition requires shimming the starter.There are ready made shims available for this purpose.

The first can be determined by a bench test with the starter off the vehicle, usually before installation. The second you have to lift the vehicle and remove the dust cover over the flywheel and observe what is going on when you are attempting to crank it.

Hope this helps, if so an accept would be appreciated.



If more information is needed, please ask me.
