Another Mini Starter question.

Hi gents.............
Installed a mini starter in a 1969 with a 1971 350. It has a TKO manual. Every first start it seems to grind as if you tried to start it while the motor was running. So I let off the key and try a second time and it starts fine. I did the best I could at checking the clearances but it hard to get to, I still have the trans in. Anyone have an idea what would cause this.

Thanks............ Joe

Re: Another Mini Starter question.

If the starter motor isn't properly shimmed to get the Japanese (Hitaci), or Chinese (Powerhouse) pinion gear on the starter to talk Amarikan to your flywheel's ring gear. Use a steel paper clip to space the gears apart (apply shims between the starter and the block).





By the way you have to use starter bolts to secure the starter motor to the block to keep it from moving around as it cranks the engine over (lots of torque being applied). These are stainless steel ARP bolts, but you can reuse your factory bolts IF they are the correct length.



Besides being a grade eight bolt they have special knurling at the base that gives an interference fit (press fit) with the block to remove any slack between bolt and machined hole; to prevent the bolt from being pulled out.

If you use regular bolts the starter will shimmy like a belly dancer when starting giving you a grinding noise.

Re: Another Mini Starter question.

Thanks for responding............ Like I said the trans is still on so it was hard to do this. I bent a paperclip enough to get it up there. It seems to go in with room to spare. However if you note the two pictures you sent they are checking this space in two different places. I checked by putting the p-clip under the bendex male tooth between two teeth (or female) on the flywheel. This is picture two. Which one is the correct way to do it? Also I used the bolts that came with the Powermaster Powermax Plus. It's funny you brought that up because it does sound funny when it turns over, even when I tried one and two shims. Currently there are no shims. I think I should be using the first picture.

Re: Another Mini Starter question.

The male tooth on the pinion gear is fully engaged at only one point. Where that point is located on the ring gear depends upon the mounting location of the starter motor. You have two circles (one much larger than the other) but two circles can only make contact at one point from Euclidian geometry.

Check your battery. Make sure it has the proper charge. I had this problem and it turned out my battery had 1 bad cell. Just a thought.
