Starter Motor Or Flywheel Issue?

[tyr32]

Hi everyone,

So Iv just had my starter motor reconditioned with brushes and bushes an since Iv put it back in Iv been having problems. When I go to start the car it sometimes sounds like it's jamming or just spinning... Iv taken it back out an have had a look, both the Starter motor an flywheel teeth seem to be fine just a few little chips from the issue I'm having.

I have put a new battery with a lot more cranking amps as my older battery, could that be part of the issue?

I would say its a starter motor issue.it would not be throwing out properly

Reconditioned by a professional workshop??? Take it back.

agreed...warranty time, especially if it wasn't doing that before the "rebuild"!

Starters not thowing out to engage the flywheel. (starter spins but does not connect to the flywheel to crank)

Remove the starter and take it back.

Still having trouble with it need some help again.

When the starter motor is out it works fine, throws out an spins like it should, but when I hook it back up it sounds like it's spinning an not catching the flywheel... But after having a few go's at trying to start it, it does connect some times an I am able to start the car, never done this before I took it out the first time so it woulndt be the flywheel right?

Please help I'm so stumped on this

Did you return it to the workshop?

A bit of info to help diagnose.

When you hit the start position, the first thing that happens is the solenoid pulls the Bendix into mesh with the flywheel.

As the solenoid reaches the end of it's travel, it bridges the high amp switch contacts which supply power to the actual starter motor, and away she goes.

So if it motors but doesn't engage, you could have a busted Bendix or the solenoid lever may have been assembled incorrectly, (easy mistake to do) and then the engagement to the flywheel is incorrect.

This is why it's best for a competent shop to mount, test and measure the Bendix throw etc.

As an aside, the high amp contacts down at the bottom of the solenoid are often a forgotten item when a starter is "overhauled".

If the starter has been run with a dead/dying battery for a while, the contacts melt.

2 things, 1 double check the entire ring gear for worn teeth, its possible that if the engine comes to rest in the same position as where the worn teeth on the flywheel line up with the starter motor it won't mesh, 2 the starter motor may throw out the drive gear but will it take a load at the same time? It's possible the one way bearing is stuffed hence it will work fine on the bench but not when it's in the car. Something as important as a stater motor you have already wasted time and effort with trying to save money having it repaired just do it right and replace with new. Hope this helps

The solenoid on top of the starter normally comes with a set of spacer rings. These rings detemine how far the solenoid throws out the starter pinion which in turn determines whether the starter pinion engages fully or partially. i would suggest that the people who reco'ed your starter may need to add or remove the spacers.

When I bought a new solenoid for another nissan i was given 3 spacers.
