A Yunfeng brand 18Y-10 small vertical steering tractor experienced repeated failures within a month after replacing its differential assembly. The tractor had to go through three complete differential replacements due to severe wear on key components such as the differential gears, planetary gears, planetary gear shafts, shaft holes, and thrust washers. This wear caused the tractor to move straight without proper steering control, making it difficult to turn. After thorough inspection, the main cause of the excessive wear was identified as improper clearance adjustment—specifically, the clearance was set too small, leading to increased friction and premature failure.
Based on years of hands-on experience, the author has developed a reliable method for adjusting the differential clearance in tractors. Here's a step-by-step guide:
1. Use jacks to lift one drive wheel off the ground from the clutch side and secure it firmly. This helps in isolating the wheel during the adjustment process.
2. Loosen the lock nut on the centering adjusting screw located on the right steering shaft bearing cover. Then, rotate the driven wheel while simultaneously turning the adjusting screw until the drive wheel can be turned easily with one hand. Once the correct tension is achieved, slightly loosen the adjusting screw so that the drive wheel can still turn smoothly with minimal effort.
3. After achieving the desired adjustment, tighten the lock nut securely to maintain the setting.
4. Open the transmission cover and check the alignment of the steering shaft gears. Use a crowbar to toggle the left and right sides of the steering shaft gears; there should be no noticeable gap. Next, turn the drive wheel to position the two planetary gears correctly. With your thumb and index finger, try to move the central reduction gear left and right—there should be no play or clearance at all.
This method ensures proper differential clearance, reduces wear, and improves the overall performance and longevity of the tractor’s steering system. It's a practical solution that combines technical knowledge with real-world application, helping mechanics avoid costly and frequent repairs.
