Gear backlash causes noise on 5000 series tractors
5000 series tractors with the 3 cylinder, 2.9L engine are assembled with spur cut gears in the front drive train. Spur cut gears are made with a backlash tolerance, which allows them to be slightly loose.
When the gears turn under a "no load" condition, the backlash will cause them to clank together. This is normal. When a hydraulic function is activated, a load will be transmitted across the gears and the noise should be eliminated.
The noise will be more pronounced at low engine speed. Proper engine idle speed should be
800-850 RPM. If your engine runs slower at the lowest throttle setting, alert your John Deere dealer at the next service interval for an adjustment.
