Attention: Do not try to buy this product directly from the website. You must call or email us first to check availability. Also, make sure to follow the gear - shifting procedures appropriate for helical gears to avoid unnecessary wear. Maintenance: Regularly check the condition of the gears, especially the 3rd/4th engagement cones/dog teeth. If you notice any damage to the dog teeth, you can easily replace them without having to buy a whole new gear. Keep the gearbox well - lubricated as recommended for smooth operation.
