I put in a stall convertor and now my new starter likes about 1/2'' hitting the flex plate. It is the LT4 starter it worked fine before I put the edge stall in that was the only thing that changed. Any ideals???

Does the starter possibly have 2 sets of mounting holes that allow it to be installed with either 153-tooth or 168-tooth ring gear?

chevyowner02

No it only has the two mounting holes. I have searched around and have seen where only a couple have had the same problem.
I just don't see why a new convertor would make that bid of a distance.

Injuneer

But the same flex-plate,correct?

And by "my new starter likes about 1/2'' hitting the flex plate." you mean the starter gear, when fully extended, is even with the ring gear, but about 1/2" side-to-side away from engaging the ring gear on the flex-plate? Or do you mean the starter gear would have to extend another 1/2" front-to-back to engage the ring gear?

chevyowner02

Yea it is the same flex plate and the gear would have to go another 1/2'' front to back to engage the ring gear.
I think I am going to go back to the original style starter and see what that dose.

Chimera96

same starter you took out and same flexplate....should bolt right back in

possible your starter took a crap but doubtful...since you have another starter try it.

FWIW I have the "vette" aka LT4 starter and it was a direct bolt in

Injuneer

Are you possibly looking at the nose of the starter, and seeing that the starter gear is 1/2" away from the ring gear, forgetting it is going to move out of the starter nose when the starter is powered, and mesh with the ring gear?

Or did you power the starter, while watching the starter gear, and it did not move out toward the ring gear, leaving the starter spinning and doing nothing?

chevyowner02

Yea I put power to the starter and it shot out the starter gear and liked about 1/2'' from engaging the flex plate. I haven't had time to mess it with it this week.
I am thinking that the starter gear isn't moving out far enough.

If you remove the starter and bench test it using a set of jumper cables and a screwdriver. You can see if the starter gear travel is correct, or the same as when installed.

Injuneer

Not a stock starter (CVR Pro-Torque) but the starter gear is almost even with the back of the flex-plate ring gear.

Is that starter for an LT1 application? Looks more like for a Gen I SBC...???

Injuneer

That is a straight bolt pattern, universal 153/168 tooth starter (two sets of bolt holes) for Gen 1 and Gen 2. It can be rotated for header clearance. Mine is about 12 years old.

chevyowner02

Well it's been awhile since I have been able to work on the car,but I did order a factory style lt1 starter.
I put it on and it works grate I don't know why the lt4 style would not work with just a convertor change. (my luck I guess)
