I was able to locate a barely used set of track chains off an IH T340 to put on my IH T4 restoration. Now that I have the chains, the grouser pads are going to be the next obstacle. The original grousers on my T4 are very well worn and have had considerable welding done to them. There are a few good ones on the chains I removed from the T340. The grousers for my T4 are 10 wide grousers but I have a local shop that could cut any width down to 10 for me. My chains require grousers with a 3.25 x 2 bolt pattern and use 7/16 bolts. I have looked in the parts book and there are numerous part #'s for different styles of grousers. It also appears at some point the chains must have changed and require 1/2 bolts. I have attached a couple pictures of one of the good grousers that were on the T340 chains. Anyone have a source for good used grouser pads? Not too many salvage machines in my area. Thanks
