Setup and Installation
This section outlines the general procedure for installing the CAM Assembly. Specific steps may vary based on your Scag equipment model. Always consult your equipment's service manual for detailed, model-specific instructions and diagrams.
- Preparation:
- Ensure the equipment is powered off, cooled down, and secured.
- Gather all necessary tools (e.g., wrenches, sockets, screwdrivers).
- Locate the existing speed control CAM assembly on your equipment.
- Removal of Old Assembly:
- Carefully disconnect any linkages, springs, or fasteners attached to the old CAM assembly. Note their positions for reassembly.
- Remove the old CAM assembly from its mounting point.
- Installation of New Assembly:
- Position the new Scag 46335 CAM Assembly in the correct orientation.
- Secure the assembly using the appropriate fasteners. Do not overtighten.
- Reconnect all linkages and springs, ensuring they are properly seated and move freely.
- Verification:
- Manually check the movement of the speed control mechanism to ensure the new CAM assembly operates smoothly and without binding.
- Ensure all fasteners are tightened to the manufacturer's specifications (refer to your equipment manual).
Operating Principles
The Scag 46335 CAM Assembly is a critical component in the speed control system of your equipment. It works by translating the input from the speed control lever or pedal into a specific mechanical action that adjusts the engine's throttle or hydrostatic transmission, thereby controlling the equipment's ground speed.
- Function: The CAM's profile dictates the precise movement of associated linkages, ensuring smooth and accurate speed adjustments.
- Adjustment: Proper installation ensures the CAM operates within its intended range, providing the full spectrum of speed control.
Maintenance
Regular inspection and maintenance of the CAM assembly will prolong its lifespan and ensure consistent performance of your equipment's speed control.
- Visual Inspection (Monthly/Before Use):
- Check for any signs of wear, cracks, or damage to the CAM and its associated linkages.
- Ensure all fasteners are tight and secure.
- Look for excessive play or looseness in the assembly.
- Cleaning:
- Keep the CAM assembly free from dirt, debris, and grass clippings. Use a brush or compressed air for cleaning.
- Lubrication (Annually or as needed):
- Apply a light coat of appropriate grease or lubricant to pivot points and contact surfaces as recommended in your equipment's service manual. Avoid over-lubrication.
- Replacement:
- If significant wear, damage, or excessive play is observed, replace the CAM assembly promptly to prevent further damage to the speed control system.
Troubleshooting
This section addresses common issues related to the speed control CAM assembly. For more complex problems, consult a qualified service technician or your equipment's service manual.
| Problem | Possible Cause | Solution |
|---|---|---|
| Speed control feels stiff or sticky. | Lack of lubrication, dirt/debris, bent linkage. | Clean and lubricate pivot points. Inspect linkages for damage and replace if necessary. |
| Excessive play in speed control lever. | Worn CAM, loose fasteners, worn linkages. | Inspect CAM for wear. Tighten all fasteners. Replace worn linkages or the CAM assembly if necessary. |
| Inaccurate speed response. | Incorrect installation, worn CAM profile, misadjusted linkages. | Verify correct installation. Check CAM for wear. Adjust linkages according to equipment service manual. |
