Hardbro GB13, Hardbro GB14, International (3067094R1) & Vapormatic (V1000 HD)

Noisy Gear Boxes. The crown wheel and pinion are near the top of tolerance range of hardness and may cause noisy gearbox. With noisy gearboxes there is a 99.9% certainty that nothing is wrong. Inspection of crown wheel, pinion and gear mesh can be made by removing gearbox cover, 5 thou to 10 thou back lash should be acceptable.

Gearbox Pulley & Input Shaft Damage. The necessity to introduce PTO revs slowly and gently, when first starting the machine rotors and also winding down PTO revs slowly to a stop or damage may occur. Some tractors, usually with hydraulic PTO’S not properly adjusted, will jerk into gear. If this continually happens damage may occur.
