2007 at the Hammond Barn

The photos show an incomplete view of the modified linkage support. Bob may be kind enough to post the completed version. Until that happens I will try to describe the difference between the photo and the final (at least for the mark I version) linkage support. We looked at the illustrated version and decided that it was going to be too floppy and would end up causing a binding pedal as Bob drives. To cure the floppiness, we welded into place a bar along the left part of the original linkage, dipping below the left bolt into the block (rather than the water outlet) to allow clearance for wrenching the bolt and then over to the segment of the original mount on the right of the water outlet, again allowing clearance for the bolt head. The completed setup feels steady under a good push and doesn't visually deflect. The final test will come when driving. The rod turns freely enough that it falls under gravity. Before working on this I hadn't realized how much wider the rod support is on 11/12 cabs are compared to 13 cab.
