Does this flexplate have a leading edge? A beveled tooth to start the engagement like all the OEM stuff has. Or is it a blunt tooth ? Those are a failure waiting to happen. They promote a non smooth engagement and aggressive wear.I have done them like that before, but I read that the clearance is supposed to be checked on the side of the pinion tooth to the wall of the flexplate tooth. Without redoing your pic, that area just below the thin arrow. I looked over the who setup and started over again and ended up putting two shims in to get clearance using a standard paper clip which measured .020. It's better but still noisier than I would like but if I go tighter, I am thinking it might drag a bit and if I loosen it up, it might be like it was before where it literally refused to engage at times. The flexplate has a couple hits in it but nothing horrible (I dressed those real easy with a fine file) and the starter drive was in better shape than I thought.
Powermaster says to measure it at the side not the root..020 is too tight. You need to be no less than .035 and no more than .050. Measure it at the root, as the picture shows.
No, aftermarket small block and yes I'm using the factory style bolts.Do you have a big oil pan with a kick out. Make sure the starter is not up against the pan causing some misalignment or the header jammed up against it. The real starter bolts has a knurled portion on the bolt to mate with the counter bored holes for the starter in the block. If you are using hardware bolts that could be an issue with misalignment. Just some more stuff to look at.
The sheet from my Powermaster #9400 shows to measure as per the illustration. It's likely the side clearance would measure pretty close, also.Powermaster says to measure it at the side not the root.So who's right? The manufacturer should have a solid idea of the correct measurement. And a note they use a standard paper clip which is what I used.
Shop I used to get my electrical components from told me not to use a remote solinoid with any permanent magnet starter, won't want to disengage is what I remember. I've had good luck with the factory minis, but I don't have that much compression.Not sure how your starter is wired, but have heard using a ford type solenoid to send power to the starter - then using a short jumper from the main cable to the solenoid terminal can sometimes cause issues.
I have a Powermaster Ultratorque 9400 also and just looked at the directions. The picture and verbiage says .020" to .035" clearance. Inserting a wire guage between the ring gear tooth tip, and valley between two starter pinion teeth. And it says you can use a #1 standard paper clip. It says nothing about side clearance. Which I bet would be fine if you get to that paper clip clearance.Powermaster says to measure it at the side not the root.
