Hi Everyone,
I am having a heck of a time with my starter eating ring gears on my 727 torque converter. I will try and explain it as best I can and hopefully someone has had experience with this before.
I started the car up for the first time not to long ago and got it running on its own. I have gotten it through a couple of heat cycles and while the timing is not perfect, it is very close. When I started it the first time, I was using the original converter with a brand new mini starter. I did run the battery down a couple of times but what it sounds like is that the starter goes through a couple of revolutions and then just slams to a stop. I am not sure that is what is happening but that's what it sounds like. I figured it was possibly a bad starter and or I got too excited and tried to start the car to fast and ground the teeth off. Truthfully I needed the proper torque converter for my set up so I was not upset.
So now I buy a brand new Hughes toque converter and another brand new mini starter (summit brand this time) and installed them. I get the car started and I am super excited thinking I am about to move on down the road to finish the interior. Then I tried to start it in the cold this last weekend and it took a while to get it started but did. I went to start it again and 3 revolutions in the, I get the same loud cracking sound and sure enough I broke teeth off my new torque converter. Summit warrantied the converter but not the starter and once I got everything back in the car yesterday, it almost happened again but luckily I didn't break teeth.
At this point I am at a complete loss. I don't think you can shim 727 starter (at least it didn't come with any) and I don't know what would cause it to do something like that.
Something that I did notice is that when I was using the bump starter vs key, the starter sounded much stronger and turned much harder then when I was using the key. Could a bump starter cause and issue like that?
Here are things about the car and items I checked
- 416 stroker motor with 10:1 compression
- Doug's Headers which is the reason for mini starter
- Engine runs and runs well. No smoking and it idles. Does not like to start cold
- No overheating
- Battery - Interstate Mega Tron Series 24 - 800 cca
- Bench tested both of the starters I have and both pop and spin as they should without hanging up. That is why I am not sure if it is the starter or not.
- I am taking back my summit brand starter to summit today and letting them know what happened to see if they will exchange it for a new one.
Sorry to be so long winded, I am just trying to be as descriptive as possible and I greatly appreciate any help you all are willing to provide. I am to the point I want to get rid of the car and just take my losses and so frustrated.
