Contents

Noise when pedal pressed

Noise when pedal released

  • Worn Gearbox Bearing (Input Shaft Bearing)

Clutch Won't Release Fully

Difficult to shift gears due to failure to fully release

  • improper adjustment of linkage. Adjust the clutch to see if that fixes the issue.
  • incorrect length of Release Bearing sleeve fitted. If you just swapped gearboxes, this is a somewhat common issue

Grabby clutch

  • Drum shoe brakes too tight, or contaminated with oil or grease. Inspect Rear Brakes and (if so equipped) Brakes#Front Drum Brakes
  • Oil or grease on clutch face
