The steering gears wore out on my mower and as usual, they had to be ordered. This time, the nylon bushing was not available. That is not a problem as I have a section of one inch round nylon on hand. I made new bushings for the new assembly as well as the two old rebuilt ones that I use while waiting for the new parts to arrive. The gear teeth wear and I can rebuild them with weld but they do not last long. At least it lasts long enough to get new parts.
