    Hey everyone I am working on a Case 721C and I am looking for the torque specs for the converter bolts. I tried to call my local dealer but the information that they sent me is not for the torque converter bolts. I am looking for the spec on the bolts that attach the 2 spacers or flex plate or whatever it is called to the torque converter.

    Hi Onemoparnut,

    this should be 4 M10 bolts. The 8.8 quality needs 46 Nm, the 10.9 68 Nm.
    M12 would need 79 Nm (8.8), 117 Nm (10.9). Secure with Loctite 262.
