915 trans helper spring and arm adjustment
 

When I put a new helper spring on, I put the large arm back on the splined shaft and in one position it touched the throwout arm and moving it one spline puts it about a half inch from the arm and the stop adjustment is bottomed out to get close.http://forums.pelicanparts.com/uploa...1393629002.jpg

Can you clarify what your question is?

Also, you may want to look at the technical articles, as there is a project for re-installing the helper spring which has pictures.

Hope that this helps.

I was concerned about the distance to the stop bolt. It is all the way in to get even close.

From the picture it looks like the release lever (big arm with helper) is out of position. After you slide it on you need a very large screw drive or a small crow bar to pry it over center of the spring and it will make a satisfying clunk as it finds its happy place. It will hold itself in place and not slide off the shaft if it is correct. The helper spring will be a few mills away from the heat exchanger.

Just reread, just to make sure I don't mix you up. All the instructions I gave are before you put the the small splined arm with the adjuster on. Hope this help.

It's snapped in position. The helper spring is almost touching the heat exchanger where the exchanger is ground out. It' just that the stop bolt has to be threaded all the way in to get close enough for the proper gap.

Looks like you need to go back one spline to where it was interfering… I did mine last week and had to pry back the release lever slightly to get the spline arm in position. Once everything was in place and settled then I was able to adjust gaps per the manual directions. Attached are some photos of mine (I was just under the car welding a bolt onto the fill plug to get that F#$%^ plug out!). Maybe you see something in these that helps.

Only other possible thought, is yours an upgraded 915 on a 1973? I thought the helper spring came along later, maybe the geometry on yours is supposed to be different. Hopefully someone here who know more can chime in.

Best of luck!

Hey! Your lock nut is on the wrong side. Hope that's the answer!!

routah is correct about the lock nut. With SSI's on mine, I also needed to hammer the flange away from the omega spring.

It's not on a 73 I sold my 73.5 Targa. It's an 86 Carrera. I moved the locknut to the other side because I needed that much bolt to get close to the arm. It seems one spline position is too close and the next one is too far.

Targa73,
Yes, all the pictures are '86 transmissions, 915/73 74G.
1973 didn't have omega spring.
