Product Description

The International Harvester TD-20 was a heavy crawler tractor produced across multiple series generations from the 1950s into the 1980s and deployed on highway construction, pipeline right-of-way, strip-mine reclamation, and land-clearing jobs across the country. According to publicly filed asbestos litigation records, the TD-20 drivetrain allegedly incorporated chrysotile-asbestos brake bands, steering-clutch friction discs, and transmission-clutch linings. IH dealer service networks and aftermarket friction houses allegedly supplied replacement bands and linings as routine service parts.
