Starter motor replacment teeth count.

[oHBoy.]

Hi,

I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating:
Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from
36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty.

Compatible with the following Nissan part numbers:
23300-20P00
23300-20P01
23300-20P05
23300-20P10
23300-20P11
23300-AA111
23300-AA112
23300-AA300
23300-08U10
23300-08U11
23300-08U15

Physically, you'd expect it to turn the motor 11/8ths faster than a standard one, but I'm not sure of specifics

I saw your intro update, are you sure you've actually had a starter motor failure? You mention it could be the alarm causing it.
I'm assuming you've got a no start issue, but what are the exact symptoms, as there could be a few reasons it has stopped wanting to start.

I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test.

Fix:

1st, car off for a hour and half disconnected battery 10mins 4th try car started

2nd, 5th try started

3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

But, per MBS206's question, what happens when it doesn't start.

When you turn the key to IGN, do the dash lights come on (then go off after a couple of seconds) - likely alarm or other electrical issue

When you turn the key to STRT do you head a clear click (the starter solenoid trying) without the engine turning (likely starter motor)

[oHBoy.]

lights are on just the one click.

Measure voltage at the starter solenoid terminal when the key is at start and it has clicked.

If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself.

If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison.
