I used 1\/2″ weldable tubing to make a shift linkage.<\/p>\n

The shifter came with a coupler<\/a> that I used on that end. I had to take down the diameter of the tubing just a little for it to fit.<\/p>\n

<\/a><\/div>\n

<\/p>\n

<\/a><\/div>\n

There is a roll pin supplied to stake the rod to the coupler. I may decide to use a more easily removable pin for the final assembly.<\/p>\n

I used 3\/8″ ratchet U-joints for the linkage. On the shifter end, I formed the tubing into a square end to fit inside the U-joint. I ground the face of the socket down to provide more surface area and to remove the chrome plating and welded it in place. On the male ends of the U-joint, I ground the tenon down to approximately cylindrical to fit inside the tubing and welded there.<\/p>\n

The joints have a little more play than I had hoped. If they introduce too much play, I will try to tighten them up. If that doesn’t work, I may need to start over with better U-joints.<\/p>\n

On the transaxle end, I used a shift rod adjuster<\/a> but modified it. I hot forged the threaded end into a 3\/8″ square to fit into the ratchet U-joint, shown here before welding.<\/p>\n

<\/a><\/div>\n

The results look pretty good to me…<\/p>\n

<\/a><\/div>\n

Still left to do is a support brace\/bearing to stabilize the rod between the shifter and the first U-joint. I think I will use an appropriately sized bronze sleeve<\/a> attached to a brace attached to the frame, although I have considered using Nylon. I will probably need this brace to be adjustable, so I will probably need to weld a tab to the frame for the brace to bolt to.<\/p>\n","protected":false},"excerpt":{"rendered":"
