Hey all,

Tried starting my Touring tonight. It didn't want start. The more I pushed down on the starter button, the more I heard a grinding sound coming from the bendix cover/ starter. Soon it became the only thing I heard. I'm gonna a gonna take the bendix cover off to see if anything is Loose in there. I'm gonna do it tomorrow when there is more light. In the meantime, does this problem sound familiar? What could it be? Thanks for any Info.

Derrick, I have found a number of Bendix covers with outward grooves caused by the mounting bolts working loose. Whenever a Bendix assembly is fitted, new lock washers should always be used. Re-bending the tabs on a used washer is a no-no. They are likely to break off and allow the bolt to come out.

Best of luck.

Hi Derrick,

It sounds like one or both of the bendix spring screws are backing out. You will likely need new lock washers. Good luck with your project, Bill

Sounds like the internal mounting bolt is loose. Mine loosens up every 2 years or so. Need to pull the cover and tighten up the bolt. I've never replaced the lock washer, probably should give that a try.

Will this loose bolt prevent the car from starting?

With time yes, I have had it stop the starters rotation on me a few times. Luckily I have a crank.

Might be a worn ring gear on the flywheel---you can check this by moving the car a bit while in high gear, to find a differant starting place on the ringgear. Do check the bendix however as this is more likely your problem...paul

Remove bendix cover screws.
Remove bendix cover.
Remove coffee beans.
Brew up a cup and enjoy.
Install bendix cover.
Install bendix cover screws.
Put new beans in generator.

Repeat daily.


Hope it's nothing major and just a lock washer or two. Finger crossed for you.

Ok, took off the cover. It was definitely loose retainer bolt. Got it snug and the sound is now gone. Thanks all!

Derrick, what did you do to keep it snug?

Just used a 1/2 wrench to get it all the way down. And made sure the tab onthe lock washer came up passed the nut to bend it down enough.

So now the question is, Why was it loose? It may be OK for awhile, but I'd install a couple of new 50 lock washers that haven't had decades of use and possible metal fatigue.
