Find the checks behind a symptom. Identify the affected part before deciding what to replace.
Also check drum drives, idler clutches and row-unit gearcases before ordering drive parts.
Grid-bar contact, pressure-plate position and cam-track wear now have dedicated inspection guides.
Start with identification. These guides cover spindles, doffers, picker bars, moisteners, drives, grid bars, pressure plates and cam tracks checks, not whole-machine diagnosis. Stop and isolate the machine before access; moving or raised components require the specified safety precautions.
20 related guides. These are inspection directions, not confirmed causes.
Bent or loose grid bars and an incorrectly positioned pressure plate need different checks. Locate contact marks and preserve the installed position before replacing spindles or ordering cotton-path parts.
