How to Adjust and Repair Clutch on Horizontal Two Cylinder John Deere Tractors

Antique John Deere tractors are hugely popular with hobby farmers, collectors, and for great restoration projects.

Adjusting the clutch is an occasional upkeep item required to keep your tractor working properly. If your tractor doesn't make it up hill, or slips when you pull a load it is time to inspect and adjust your clutch. A properly adjusted clutch is easier to operate, more efficient, and longer lasting.

Difficulty: Easy

Instructions

Things You'll Need:

• Needle nose pliers
• 3/4" socket on ratchet
• New Cotter Pins
• Regular Screwdriver
• New Facings if needed

1. Stop tractor and shut off engine.

2. Remove clutch dust cover, may require use of a screwdriver.

3. Remove three cotter pins from castellated adjusting nuts.

4. Tighten each of the nuts an equal amount and test clutch lever. It should engage and disengage with a snap.

5. Test clutch by driving up a grade or pulling a load. If the clutch is still slipping tighten the nuts another increment and retest. If excessive effort is required to operate clutch renew facings and readjust.

6. Once adjusted replace cotter pins and dust cover.

Tips & Warnings

• Clutch is an over-center design. The clutch will pop past center to engage and disengage.
• A slipping clutch generates a lot of heat which glazes the surfaces of the disc and will prevent them from gripping. A light sanding can improve the friction properties.
• Old facings are often worn thin through use. Renew if flexible, oily, or shiny.
• If clutch is slipping despite adjustment pull three nuts, outer plate, facings, sliding drivers and inner driving disc. Replace all facings and inspect for any broken pieces.
• Do not attempt to adjust clutch with engine running. Stop engine, turn off ignition.
• Test clutch with plenty of room to maneuver. If clutch is adjusted too tight it may be difficult to disengage mechanism. Provide room for overrunning.
• Consult repair manual or specialist if you have any questions.
