Haven't had a chance yet to look at the starter, but will hopefully on New Year's Eve - off work!

 

@ebinmaine did you ever get a chance to look at the starters on your bench? Any idea what the washer materials are? I will replace when I get the starter off - hopefully the impact works to get that nut off!

 

I'll take poke at them this weekend.

@Alrashid2

Here's a few pics & some information. 

 

These are the two starters. 

One is from my 1975 C160 Automatic K341. 

The other I don't recall. They're physically identical from what I can see.  

 

 

 

The end as assembled BEFORE removal. 

 

 

1/2" socket on an impact driver buzzed it right off by holding the gear with a GLOVED hand. 

 

 

Inner "cup" washer. 

 

 

 

 

 

This fits over the straight section of the shaft. 

Note that the spring has not contacted the inner side of the cup at any point. I believe a plain flat thin washer here would be fine. 

 

 

Outer washer. 

 

 

 

 

This washer is the diameter of the threaded portion and does NOT go up on the straight section. 

 

Note that in the picture you can see a small centering ring which the spring would ride on. 

That would help keep the spring from binding on the shaft but if you can't find one a flat THICK washer would do the job.... possibly for reduced lifespan though.  

 

 

Clean all parts thoroughly and reassemble with DRY LUBE. 

I use a graphite powder. 

 

Reinstallation was done with the same impact driver and GLOVED hand.

THANK YOU @ebinmaine! I wonder how long my starter was running with NO WASHERS until I busted it. No wonder the spring disintegrated - probably got binded up at some point. I'll see if I can find some washers tomorrow to make this better! No idea how/where I'd find replacement pieces but thank you so much for the detailed photos and step by step instructions! Will report back tomorrow

Thanks again everyone for the advice and @ebinmaine for the pictures. 

 

I pulled the starter again, and lo and behold that impact driver pulled the nut off no problem (did tweak the spring a bit but I got it good again). Dug through my washer drawer and found 2 that fit pretty well. Reinstalled, started her up a few times, and she worked no problem. Spring shouldn't get torqued and break again now! Thanks guys!

 

Update: added photos. First is the before, second and third are after with washers added

Great thread, thanks to everyone who has contributed!

My M14 has a flat spot, so I'll be jumping into clean & repair as needed.

Has anyone compiled parts list(s), and are the bendixes readily available?  Are these just ebay parts?

 

Thanks!

@HyperPete DBelectric  has a parts kit that has brushes, plastic brush holder , insulating washers, 2 bushing (one incorect). Google or eBay.  When you say bendix I’m assuming you mean gear and spring. You have to find these NOS on eBay individually.  The bushing in the gear and front cap wear the most. The bushing in you gear can be pressed/drilled out and replaced. The cap bushing also can be pressed out and replaced. Use a socket for a driver.  See measurements higher up in this thread. The rear cap bushing usually has very little wear. 

PS do no use grease or oil lubricants only dry graphite or silicon spray that dries.

Thank you.  Yes, the drive gear used to be called a bendix - guess that's a throwback to my old automotive days.

Might that be available from someone like mcmaster-carr?

I've always called them a Bendix gear too
