Plastic Wear Blocks Reduce Chain Wear

Plastic wear blocks reduce chain wear COMBINES Accessories 13-1-33 "I got the idea when I saw other farmers slipping small wedges of plastic between the chains and wood block tighteners on their Gleaner combines," says Ron Rosman, Davenport, Wash., who started manufacturing plastic wear blocks for Gleaners and any other machine with wood tighteners or idler sprockets. Rosman's wear blocks have a 3/16-in. thick wear area of high grade plastic. "They last 4 to 5 times longer than wood blocks, increasing chain lift and keeping chains tighter. I've had them on my own machines for 3 years and they work great. They seem to last forever with almost no wear," says Rosman. The 1 3/4-in. wide wear blocks were originally designed for conventional Gleaner combines because of the high number of chain drives and the wood blocks used on them, but they can be used on any other chain drive. Rosman uses them on the feeder and unload augers on his IH Axial Flow combine as well as on rod weeders, fertilizer and spray equipment, sawmills and other equipment. "They're great under tough, dirty conditions where you don't want to use a sprocket idler because you don't want to hold the chain in a fixed position," he notes. Plastic wear blocks sell for $3.45 apiece or $2.42 apiece for five or more. Although designed to replace the blocks on Gleaner combines, they can be adapted to other equipment by changing mounting bolts.
