Need help with bolt otgether converter

#1 Post by rickou812 » Mon May 28, 2012 2:56 pm

I have a 10" converter and have broken the sprag twice now. The converter has undoubtedly has a ford stator, has 3 key ways, 2 wide and one narrow. I contacted Sonnax and they sent me a FDGM-MD-1, mechanical diode. It has the 3 key way for the ford stator and GM inner spline.

The problem is that I am not convinced that it is not locking backwards. The diode will only go in the stator one way due to the key way arrangement.

I have reassembled and bolted the converter back together, but would like to have confirmation on which way the diode is suppose to click before installing.

I have a stator shaft that I can place into the converter to spin the stator with.

THANKS for any help,

checking diode with converter assembled. put a stator support spline into the diode spline and turn "quickly". The diode should ratchet clock wise and lock counter clock wise
