Allen wrench for Conn 88H Gen2 and 62H Gen2

Post by ddsbstrb »

Would any of you repair techs happen to know what size Allen wrench works on the set screws on the valve lever/levers on the Conn Gen2 88H and the Gen2 62H. My Allen wrenches are too big or too small.

Thanks for the information.

Hi Denny, they're either 5/64" or 3/32"
More than likely 5/64 and the head is stripped from the screw being too small to adequately tighten the lever.
Best to have the screw tapped out to 3/32" and use a larger screw.

I finally got a complete set of Allen wrenches, and it looks like it is a 1/16 wrench which fits the Conn Allen Screws.

I presume that these are "standard" (SAE), not metric set screws?
