While the steering wheel is not moved, the torsion bar (2) is not twisted. There is no gap between the input shaft (1) and sleeve (3). This makes no pressure difference between the chambers “a” and “b” of the cylinder, which keeps the ball nut (4) and sector shaft (6) in their positions.
This integral power steering mechanism consists of the following two major components as shown above: hydraulic control valve and steering force assist hydraulic cylinder. The control valve is housed in the casing and composed of sleeve (3), input shaft (1) and other parts. The hydraulic cylinder, on the other hand, is composed of gear box… Read More »
This tractor is equipped with integral type power steering that of rotary type control valve with torsion bar. The oil sent from hydraulic pump (7) flows in gear case through control valve (4) and moves rack (2). And at the same time, the oil from gear case flows to hydraulic pump or HST unit to… Read More »
The integral type power steering is used on this tractor. This steering system is composed of steering wheel, steering joint shafts, steering gear box and other components shown in the figure.
1. Measure the front axle case bosses O.D. with an outside micrometer. 2. Measure the bracket bushing I.D. with an inside micrometer and calculate the clearance. 3. If the clearance exceeds the allowable limit, replace the bracket bushing. 4. If the clearance still exceeds the allowable limit, replace the front axle case. Press-fitting Bushing… Read More »
1. Stick a strip of plastigauge to three spots on the 42T bevel gear (1). 2. Fix the axle flange and front gear case. 3. Turn the axle. 4. Remove the axle flange from front gear case and measure the amount of the flattering with the scale and get the backlash.… Read More »
1. Stick a strip of plastigauge to three spots on the 16T bevel gear (1). 2. Fix the front axle case, bevel gear case and front gear case. 3. Turn the axle. 4. Remove the bevel gear case from front axle case and measure the amount of the flattering with the scale and get … Read More »
1. Set a dial gauge (lever type) with its finger on the spline of spiral bevel pinion shaft. 2. Measure the backlash by moving the spiral bevel pinion shaft by hand lightly. 3. If the backlash is not within the factory specifications, change the adjusting collars (3), (4). Change the adjusting collar… Read More »
1. Install the spiral bevel pinion shaft assembly only to the front axle case. 2. Measure the turning torque of spiral bevel pinion shaft. 3. If the turning torque is not within the factory specifications, adjust with the lock nut. If the turning torque is not able to adjust by lock nut (2), change the… Read More »
1. Set a dial gauge (lever type) on a tooth of the differential pinion. 2. Fix the differential side gear and move the differential pinion to measure the backlash. 3. If the measurement exceeds the factory specifications, adjust with the differential side gears shims. (Reference) • Thickness of adjusting shims: 0.40 mm (0.016 in.) 0.60… Read More »
