Starter headache

[REDWOLF]

Is there any other electrical problem, other than a bad starter solenoid that would cause the starter to just spine and not engage. It does this intermittently, it will go for weeks and not do it and then it will do it every other time and then back. My M1009 is all stock. Thanks.

I believe that if the starter spins, then the solenoid is doing its job. The problem would then be with the bendix.

Try a tap with a hammer, or just have it rebuilt? I imagine whatevers wrong will get worse one day

There are a couple of reasons that could happen. You may have some spots on your flex plate where the teeth are chewed off. More likely, the teeth are not moving into proper position.

It could be the solenoid. On Delco starters the solenoid has a run out function. That is what the magnetic plunger hinged to the starter drive is for. Also check that starter drive is clean and lubed.

Miss aligned starter
loose starter
bad starter

You really just have a slipping Bendix. The gear has engaged the flywheel but slips in it's clutch. If the starter motor spins the solenoid is doing it's job. The Bendix is a overrunning clutch and can wear and not hold all of the time. I just saw one for sale in a popular auction website for about thirty bucks. Easy to install to. While you have the starter off look at your brushes for wear as well.

Don't forget to check your bushings while you're at it. They are a major wear item. The armature shaft can wear right through and start to dig into aluminum. You'll have slower cranking speed from the sagging armature rubbing against the case.

I did mean to say bendix. This was a new gear reduction starter, and had been doing this sence day one. Should have replaced it then. Also if the flex plate was missing teeth, I belive. if you could get it to catch when you cranked the truck when it came around to the bad spot the starter would jump back out. Thanks I was not sure if anything with the starter glo plug system could cause my problem. Have to see if I can get my starter replaced under warranty.

Since it is a gear reduction starter never hit it with a hammer! Most have ceramic magnets that will be destroyed by hammer blows. I am replacing my flexplate because it too had missing teeth. I blame the poor gear bevel on the aftermarket flexplate which was installed in 2008. Go with an OEM or NOS. I bought one from Saturn Surplus, much better bevel to the teeth. I am also replacing the engine rear main seal while I'm at it, it was not leaking but upon inspection the old rope seal was gone. New flex vs. Old
Got new tires for it too.

Had a couple "new" starters that would do this.
Weak solenoid was not throwing the drive forward far enough.

Is the starter getting 24 or 12 volts?
