Components of the Craftsman Model 917 Steering System
Main Steering Parts and Their Functions
The steering system in the Craftsman Model 917 consists of several interconnected components that work together to facilitate directional control. The primary parts include:
- Steering Wheel – The interface for the operator to control direction.
- Steering Shaft – Connects the steering wheel to the steering gear, transmitting torque.
- Steering Gearbox (or Steering Box) – Converts rotational movement from the steering wheel into lateral movement to turn the wheels.
- Drag Link – Connects the steering gearbox to the steering arms, transmitting motion.
- Tie Rods – Link the steering gearbox to the wheel assemblies, facilitating wheel turning.
- Steering Arms – Connect the tie rods to the wheels, enabling them to pivot.
- Pivot Points and Bushings – Allow smooth movement and reduce wear at connection points.
Additional Components and Accessories
Other parts that support the steering system include:
- Steering Column
- Adjusting Brackets and Supports
- Steering Linkage Bushings
- Steering Wheel Knobs (for added control)
- Alignment Kits
Detailed Examination of Key Steering Parts
Steering Gearbox
The steering gearbox is a critical component that translates the rotational input from the steering wheel into lateral movement to turn the wheels. In Craftsman Model 917 tractors, the gearbox may be a rack-and-pinion type or a sector gear type, depending on the model. Over time, gear wear, lubrication issues, or damage can impair steering response. Replacement of the gearbox is often necessary if it becomes excessively worn or broken.
Tie Rods and Drag Links
These components are responsible for transmitting movement from the steering gearbox to the wheel assemblies. Tie rods are adjustable to set proper wheel alignment, which influences steering precision and tire wear. Damage, bending, or corrosion can cause steering looseness or misalignment. Regular inspection and replacement are recommended when signs of wear appear.
Steering Arms and Linkages
The steering arms attach to the wheel hubs and pivot to facilitate turning. Worn or bent arms can lead to uneven steering and difficulty controlling the tractor. Proper lubrication and periodic checks help prevent premature wear.
Steering Wheel and Shaft
The steering wheel is the operator's interface and should be comfortable and responsive. The steering shaft connects the wheel to the gearbox. Worn or loose connections can cause slack or play in the steering, reducing control. Ensuring tight fittings and replacing worn components is essential for safety.
Common Issues with Craftsman Model 917 Steering Parts
Steering Play or Loose Steering
This issue often results from worn tie rods, bushings, or loose connections within the steering linkage. It might cause difficulty in maintaining a straight line or precise turns.
Steering Wheel Difficult to Turn
Caused by insufficient lubrication, damaged steering gear, or bent components. It may also be due to debris or dirt accumulation in the steering mechanism.
Uneven Tire Wear and Misalignment
Worn or improperly adjusted tie rods can lead to misaligned wheels, causing uneven wear and poor handling.
Steering Gearbox Failure
Over time, the gearbox may develop internal damage or gear wear, leading to complete steering failure or erratic behavior.
Steering Wheel Free Play
Play in the steering wheel might indicate worn bushings, loose fittings, or a need for adjustment in the steering linkage.
Maintenance and Replacement of Craftsman Model 917 Steering Parts
Regular Inspection Practices
- Check for excessive play or looseness in the steering wheel.
- Inspect tie rods and drag links for bends, corrosion, or wear.
- Look for leaks, damage, or wear in the steering gearbox.
- Ensure all connections are tight and properly lubricated.
- Test for smooth operation during steering maneuvers.
Lubrication Tips
Apply appropriate grease to pivot points, tie rod joints, and steering gearbox components as recommended by the manufacturer. Proper lubrication reduces wear and prolongs component life.
Replacing Steering Parts
- Identify the faulty component, such as a worn tie rod or damaged steering gearbox.
- Safely lift the tractor and secure it on jack stands if necessary.
- Remove the damaged part, following manufacturer instructions or repair guides.
- Install the new component, ensuring all bolts and fittings are tightened to specified torque values.
- Check alignment and perform a test drive to verify proper steering function.
Aligning the Steering System
Proper wheel alignment is crucial for optimal steering performance. After replacing steering parts, consider professional alignment services or follow manual procedures for adjusting tie rod length and ensuring wheels are parallel.
