Drive Sprocket Support Assembly: Inspection

  1. Check 2nd clutch piston assembly for damage. If seal is damaged, replace 2nd clutch piston assembly. Check bushing and bearing for excessive wear or damage. Check driven sprocket support for plugged feed holes, damaged seal grooves, stripped bolt holes or damaged machined surfaces. Check for dislocated or damaged springs.
  2. Inspect valve assembly for free operation. Use ATF to inspect for valve leakage. Ensure valve is in fully seated position prior to checking for leaks. See Fig 1 . Remove valve using 1/4" drift and mallet only if inspection indicates a problem or a leak is detected. Clean all parts and dry with compressed air.
