High Stall Torque Converter - broken starter nose
Posted by: Darrin ()
Date: August 20, 2018 07:41AM

Hi all,

I just got off the phone with Clarks, but their techs were busy so they said to call back later. Will try here.

Has anyone installed one of these?

I did on a fresh 140 engine with a good transaxle that had no issues with a stock torque convertor.

With the high stall and the new engine, I now broke my second starter nose. First one that broke was working fine on old engine. This could be due to a problem with the TQ convertor ring gear, or, I guess, may just be because the engine is still tight.

Anyone here break starter noses with a high stall TQ converter from Clarks?

Anyone here break starter noses on newly rebuilt motor (since it is tight)?

I have only ever had this issue on cars with bent/damaged ring gears, but this one is brand new and looked perfect.

Thx much

I've never heard of breaking starter noses due to a tight engine.

Does the engine have a bit higher compression, and any kickback during crank?
I’ve seen hi-compression engines do that, and I did it on a diesel with starting fluid without it spinning. Last time I did that!smiling smiley

Not a high compression engine. Has NOS 140 heads that were lightly ported and all clearances (bearings etc) are in spec. Timing set at factory spec.

Thx

2 things to check? If you have the late 8409 crank are you sure you have the correct LM flex plate? and is it installed correctly? Dish towards the Bell housing? EM and LM flex plates are different, Also check the run out on the TC's ring gear in both directions and see if its running true?

Thanks for the questions and vote of confidence, but, I do still screw things up all the time despite (or maybe because of) a lifetime of Corvairing!

But, in this case, I am confident that I used correct LM flex plate (with no cracks) installed correctly. Of course all installed now so would have to pull things apart to check out of round on the ring gear.

I have a Clark's high torque starter on hand so may try that if nobody chimes in with similar experience and Clarks has had no problems reported like this.

Very annoying problem as the engine runs great and the rings seated very quickly and just do not want to pull it apart again.

You can check the ring gear run out with it still bolted in the car as there are access points, First thing I would check!

D: I (and maybe you!) have a dial indicator with a magnetic base that we (or you, again!) can stick on and insert the "probe" thru one of the TC housing openings to check for run out. I agree with Motohead! Start with this. I also have plenty of starter noses if your stash starts to run low. Later... G

Can't you check the ring gear through the large cooling hole on the bottom right?

Wasn’t there some posts about auto bellhousings distorting? Seems like that might be a cause.

Hope you get it figured out.

Yeah, indicator is next. Nobody who is using one chimed in. Will call Clark’s again too.

Darrin there is only one swap that I am familiar with here in Denver. 1966 140/pg and he did it last year. He uses the car often including a couple of out of town excursions and has had no issues using his stock starter. Good luck with fixing yours too.

Thx for the feedback on others in use. The torque converter looked perfect. Will confirm that. I like the converter in action.

Darrin, what is the noticeable RPM difference with this unit?

No tach on this Monza and different engine than removed, but my impression is that takeoff is around 400-600 RPM higher than standard TC....but that is just a guess. Clark's claims a bit more.

I can clearly state that it is not extreme and a nice addition to a 140 PG, but did not change my life or turn the MoreDoor Airvair into a rocket. Another very good upgrade from Clarks.
