95 240SX, new starter: engagement issue

[EstoMax]

Hey Techs,

My old starter just gave out in my 95 240sx KA24DE. I got a new one at schucks and noticed that it came with documentation saying there are two starters, 8 and 9 teeth, and that they are interchangeable, so i can install the one they gave me either way. I installed the starter and the car started up smoothly. It cranks faster then the old one and has a cool higher pitch sound to it.

Anyways, the problem i have noticed (So far only when cold) Is that sometime after i start cranking, then on the first or second 'turn-over' the flywheel seems to come to a stop for a split second and then continues cranking. It almost sounds like the starter teeth/flywheel jam into each other. The car always starts up fine in the end though, besides this abrubt jam. The engine has been rebuilt and one of my donor engines was from an s13, so I may or may not be using an s13 flywheel (can't recall, but most likely it is the s14 one)

Question: Do s13's and s14's use the same starter? Could the 8/9 teeth starter cause a problem with the flywheel/starter teeth jamming intermittently (40% of the time so far it seems)? Could this problem be related to the starter not being installed correctly (not sure where one could fubar this up though haha) This probably isnt good for the starter motor in the long term

cheers for any input!Marko

doesnt sound good. check rockauto and see if they have the same part number for s13 and s14.

sorry i guess i shoulda checked that before, but yes, online parts store (checked oreilly/schucks) come up with same part number for s13/s14 starters. so they are the same.

the old starter never did this also..

so today the flywheel/starter jammed like 5 times in a row when the car was warm (usually only jams once and then not again until it decides to on some other starting process), before cranking normally for a few seconds and starting.

so i went and took the starter out to take some pics of flywheel/starter.. everything looked ok i think..

old starter, teeth sides are worn... is that ok?

new starter, teeth look fairly new still, maybe it needs to 'break in?' lol

and a candid shot of the flywheel:

hope you guys have some more input now

cheers,Marko

this forum is dead. try the technical and general forum. say you have a pic in title and that will draw more people. your starter could be defective which is common these days. the solenoid might not be pushing the teeth in all the way or you may have the wrong starter. the online mechanic has not been here for at least a year, btw.

test yourself or take back to store.
