8N Won't Crank

KenB1672 · Oct 9, 2010

I have an 8N that ran fine last time I used it (about 3 months ago). When I went to use it recently the starter would not crank. The battery was 3-4 years old so I replaced it. That did not do the trick. I tried to jumper the starter around the solenoid thinking the solenoid was bad. When I jumped the solenoid the starter engaged, but would not crank the engine. Thinking the starter was bad, I had it rebuilt. I just reinstalled the starter and I have the same issue.

Can anyone offer up a solution?

Troubleshooting the problem before you started replacing parts would have saved you some time & money.

I assume that the starter motor turns over, but does not turn the engine over. Is that correct?

The ring gear is slipping, the ring gear is missing teeth or you have a bad bendix that wasn't replaced when the starter was rebuilt.

Front or side distributor?

If it's a side distributor, look through the timing port for a loose ring gear. If it's a front distributor, pull the starter to check.

Can you turn the engine over by hand by way of the fan. Fan belt has to be tight to do so but you should be able to do so. If you can not try pulling the plugs out and trying it again. It could be locked up or have one cylinder full of gas or water and that will keep one from turning over and act like you say yours is doing

The engine does turn over by hand which tells me that it is not locked up.

I will try to pull the plugs to see if it turns over freely.

One item I did not mention in my first email is. That I can turn the key to the on position and when I push the starter switch there is not response from the starter. Could there possibly be a shorted wire somewhere? I would like to first get to a point where when I push the switch I get a response from the starter.

Thanks

You could have a bad wire or a bad connection or a bad battery cable etc. Try taking another good battery and use jump cables and hook to the battery then one of the other ends of the cable to a good ground and the other to the start stud. Make 1000% it is out of gear when doing this. If it turns over doing that then you problem if from there back if it does not turn over it is the start its self or the ground of the starter to the block

" That I can turn the key to the on position and when I push the starter switch there is not response from the starter."

That is exactly how it is supposed to work if your wiring is OEM. The ignition circuit is separate from the starter circuit. The key provides current to the coil. The thumb switch provides current to the solenoid.

If the engine isn't locked up, you have a bad bendix or ring gear.
