Hittade iallafall info ifrån USA, där JD officiellt skrivit i något som kallas "service bulletin", något som går ut till service-verkstäder kanske? Där kommenterar dom missljud från vissa av deras motorer så här:
" 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. "
