Hi dustyr72. Your info is very good. Yes, we made our axle pads out of the the common white, 15 to 20 mm thick solid nylon type kitchen cutting boards that you can buy at any super market for a few dollars. The plastic wear plates have not been touched since they were installed a half dozen years ago. I have used this board on a few steel to steel wearing faces and it lasts for years. Can't recall exact dimensions without looking at the combine but we used about 1" thick steel, tapped to take the large axle adjustment hold-in bolts as the mounting plate for the plastic wear plate. This steel plate then served in place of the usual nuts for these bolts. Maybe use some loctite to ensure the bolts don't come loose although we have never had any problems. The front face of the steel plate was tapped to take 2 of 1_2" [ or 3_8" ] bolts. The plastic wear plate cut to size from the cutting board, was drilled and then roughly countersunk with a large drill to match these tapped holes to enable the plastic wear plates to be attached to the heavy plates with high tensile counter sunk bolts which we made sure were well below the wearing face of the plastic plate. Any space adjustment is done by putting a few sheet metal shims between the plastic wear plate and the steel plate. Very approximate material required; a solid plastic cutting board, 2 of 1" x 5" x 8" steel bar or thereabouts in size, and 4 of 1_2 x 1.1_4 [ or 3_8 diam or 1" length ] HT countersunk bolts. A bit of messing around to get the right fit and clearances is required. CostIJ should be well south of US$50. Rolf can round up the dimensions of the materials if you want them but it is very simple to make and the clearance between the frame and the pad on each side should be a bit less than 3mms. The pads come up against the frame when the turning loads are placed on the axle. They then take these loads off the central pivot tube which has been known to fail when the pads are not installed. Hope this gives you a starting point for the job. All the best.
