10 Tips to Save Wear on your Kubota’s Clutch

10 ways you can save wear and tear on your Kubota’s clutch and prolong its life:

  1. Do not ride the clutch! Keep your foot off the clutch pedal whn not using it. The extra weight from your foot will cause the clutch disc to slip and the clutch to burn. Bad!
  2. Periodically adjust the clutch pedal free play. The play of the clutch pedal is governed by the clearance between the release lever and bearing. The clearance changes as the tractor is used. The general tendency is for the play to increase at the beginning but will decrease with use. If the free play is zero the clutch would eventually begin to slip because the release bearing would be turning at all times! If this is not adjusted to gain some clearance, then the bearing will overheat, may become stuck resulting in a worn and scorched clutch disc.
  3. Quick disengage, slow reengage. Depress the clutch speedily to disengage the clutch and return the pedal slowly to reengage it. This simple tip minimizes a lot of clutch disc wear.
  4. Lubricate clutch release bearing. Figure out what the clutch release bearing is and get in the habit of lubricating it every time you change your tractor’s oil.
  5. Do not “dump” the clutch. Do not use the clutch to jerk a load or to abruptly put the tractor under load. Do not dump the clutch to rock your tractor if you are stuck (engage your differential lock if equipped). Ease a clutch, do not dump it!
  6. Keep disc off flywheel if storing for extended periods. Place a wooden block under the foot board to keep the clutch disc off the flywheel when storing your Kubota. This prevents the disc from rusting to the flywheel and becoming one rusted immovable mass.
  7. Do not depress the clutch when not in the seat. Depressing the clutch from beside or behind the tractor is a safety hazard. Use common sense.
  8. Do not bypass the clutch safety switch. Again, we see this from time to time.
  9. Keep clutch disc free of oil and condensation. Oil and water will cause your clutch disc to slip and prematurely wear. Inspect the rear engine seal and transmission input shaft seals for oil leakage. There is a drain at the bottom of the clutch housing that drains condensation. Make sure this free of debris, dust and mud. Early Kubota L175/L1500s do not have this drain, so, make one in this case.
  10. Replace all clutch components when servicing. If you do have to replace a worn clutch disc, service all components of your clutch while you have the tractor split – do not just resurface the disc and carry on. Areas to look at would be:
    • resurfacing the flywheel
    • lubricating the clutch release bearing
    • adjusting clutch free play
    • resurfacing or installing new clutch disc

    Hi, Vic, had a L2202 with a clutch that won’t release, obviously can’t change gear, but we turn off the engine,put it in gear then wind it over to start so we can move it. It,s in the workshop now so there won’t be any need to continue doing this. Any idea what the problem is? It was being used at the time then suddenly jammed on. Thanks

    Keith, Could be a few things giving the problem, but since you were using the tractor at the time, I’d start by getting a look at the clutch release bearing. Peel the inspection cover off the RH side of the clutch housing and have someone operate the clutch pedal.

    Check that the shift fork that slides the release bearing back and forth is not broken. If one side of the fork is broken, the release bearing gets actuated with uneaqual pressure, jamming itself on the main transmission input shaft.

    If that’s OK, then see if the bearing is sliding freely on the main transmission input shaft. Should have a full range of motion, smooth and deliberate.

    This bearing has a grease nipple on it, and if it’s like most Kubota tractors, it hasn’t seen a stroke of grease since it rolled the assembly line, so nourish it while you’re in there!

    Next, observe where the bearing contacts the fingers of the clutch disc. These fingers should be “towered” up and not appear “flat”.

    If they look flattened out, it’s clutch time.

    If that look OK, then it’s possible that the disc is frozen to the pressure plate or flywheel or both. You’ll be doing the hump and bump trying to free that disc up.

    Either way, let us know what you find once you’ve got that inspection cover off.

    Crikey! Just a broken link on the arm for the throw out bearing forks. It had to be on the inside,not on the outside. Consarnitt!!

    I have a 2001 M6800 that has a dry clutch. I cannot find anywhere how to adjust the clutch. There is a bracket right behind the steps into the cab on drivers side that is a cable and has 2 jamb nuts that takes a 12 mm wrench to loosen. Behind this closer to the middle of the tractor or behind the fuel tank is another arm assembly that has an adjustable turnbuckle bu I do not knwo what this adjusts. My clutch pedal is right at the top and I need to know what and how to adjust. I appreciate your help in advance. Does my tractor have this grease fitting on the release bearing?
