Drive Link Assembly

NOTE: See COMPONENT DISASSEMBLY & REASSEMBLY  for exploded views of all internal components. See Figure for thrust washer and thrust bearing locations. See Figure for seal location and identification.
  1. Remove thrust washers from sprockets. Grab drive link chain above drive sprocket and pull toward transaxle case. Measure drive link chain clearance to case. If clearance is less than .50" (12.7 mm), replace drive link chain.
  2. Mark position of drive link chain for reassembly reference. Noise may occur if chain is not installed in same direction as removed. Pry up driven sprocket. Remove turbine shaft and drive sprocket, driven sprocket and drive link chain together as an assembly. See Fig 1 .
  3. Remove drive sprocket and driven sprocket supports from transaxle case. See Fig 2 . Ensure scavenge tube seal stays in support. If not, check support for damage. Remove input speed sensor and wiring harness.
