tshebib, et al:

I just wanted to update you guys regarding my two ring gear failures in my race car and what happened with the third ring gear.

After the second failure, I surmised that the "Factory" ring gears I was getting were the problem. After all, the teeth were being broken off in a way that suggested the metal was too hard.

So, I installed a ring gear from Kennedy made by Kennedy and replaced the pinion gear on the starter. These new parts have solved the problem. I just took the engine out my race car and the ring gear and pinion gear teeth look great.

I can't prove the factory ring gears were the problem, but that is where my money is....

Scott, I'm with you on this one. It's been over a year now since I put the Kennedy ring gear in and everything is working great! The first month or so after installing was a little stressful though..... will it start, will it start???

Guys, has anyone got a good email address for IMI?
I am trying to send them some pictures of a problem I have with one of their starters that needs a new pinion, but they aren't responding to their sales@hitorque.com mailbox.

Bill,

I know you are in Australia, but you best bet is to call them. Here is their number:

Ming starter gear was also churned at the 3 120 degrees.

This is the correct starter for a g50+ M64 with lightweight flywheel kit.

This ring has maybe 1000 miles on it.http://forums.pelicanparts.com/uploa...1587870682.jpg

The starter is a HI-Torque starter. From the markings it seems it was engaging fine.

It did start OK for about 4 months then issues started.

You should start a new thread this one's from 2012.

That is a different failure mode than I saw with the ring gear I was using. The failure in your photo looks like the solenoid is not pushing the pinion gear out far enough or it is not retracting it far enough after the car is started. I saw entire teeth breaking off and that is not what your photo shows.

Sorry to see the mess but aren't these aftermarket high torque starters all over the map in terms of fit, design and quality ? Why not go back to factory specs the good old original German part ?

The "Hi Torque" starter from IMI Performance Products is not "all over the map" in terms of fit, design, or quality. I have one of the IMI-101N models and would not hesitate to buy another for my race car.

My problems with the ring gear were not related to the starter. Rather, the ring gears were incorrectly heat treated and was too brittle. I bought aftermarket from Kennedy to fix it....

Bingo, that is my thinking. How did you confirm this if you don’t mind me asking?

The fit and finish on my hitorque starter is pretty good. I have a g50/01 going on an M64 so I needed a custom starter.

It seems to me that the 2 options you are listing may be contradicting.
50% of the pinion of the starter is engaged. Does it mean that the starter begins to spin before it is fully out?

And are you saying that the pinion is not being retracted fast enough after the car starts, thus leaving some room for it to "drag" against the ring gear?

Thank you for you help
