Re: {Chrysler 300} Replacement starter 1961 300G

Hi , It will not spin with full force unless big contacts make connection   In back . That happens only if solenoid core moves all the way in . If “ sticking “ it won’t make the contacts . If it makes contacts pinion is all the way out and had to be engaged . Period . But there is a ratchet mechanism there at pinion — as without it , when engine catches it would back drive the starter pinion to 10000 rpm . So when torque reverses ( engine drives starter ) it releases the mechanical  connection , and overruns till you release key , and pinion then withdraws by solinoid. This mechanism can have rollers or saw teeth , can get beat up and wear out , not engage when it should or be stripped teeth , lack of lube etc 

Note Bendix drive does same thing without a  solinoid by a screw thread on shaft under the  pinion , when motor starts it drives pinion back into starter . But those are mostly on smaller engines than ours .  

Hope this helps ,

John

The shop manual has an exploded diagram of the starter and will tell you what you need to know to fix it. Otherwise bring it to your closest reputable auto-electric starter/alternator shop, every city has two, and have it fixed.

I agree the starter and solenoid function fine but I think the solenoid may get stuck on the down motion which prohibits the grear from engaging. When I cleaned and lubed it it worked for about a week without issue. I don’t understand what the anti back mechanical is.

>> I have removed and cleaned my starter 5 times. Each time I get a few more cranks without it just spinning then it spins for the first two three or four times then it will engage. The solenoid was sticking the first time I cleaned. I thought it solved the problem. A week later the same problem. Does anyone know where to get a solenoid or replacement starter? I can’t find anything similar. Thanks Richard
