Proper Spline Mesh

Posted by Joe (IN) on January 06, 2005 at 06:52:47 from (66.73.129.57):

I'm trying to replace a damaged, rare aftermarket PTO shifter coupling in a 600 Ford. It's part of an auxilliary transmission kit and is longer than stock to accomodate the added tractor chassis length. Absolutely no chance of finding a used or new exact replacement. I have found an alternative coupling out of a different model machine that has the correct splines on both ends and is the proper diameter. It is longer than the stock coupling but not quite as long as this aftermarket part. I have cyphered the original amount of PTO shaft to coupling spline engagement to be 1 1/4". With this alternate coupling, it would be 3/4". The shaft diameter is 1 1/8". Any opinions or data on what the minimum amount of spline engagement in an application like this would be and whether or not this would fly? If this won't work, I'm going to have to try to splice a section of the old coupler onto the new one and I'm not too kicked about that.
