Description
5/8″ CLEVIS
Part Number: FSD680C
Direct replacement (cross ref) for AS3000.
Product Overview
This 5/8 clevis connects the brake chamber pushrod to the slack adjuster in an air brake system. It replaces OEM part AS3000 and is used on heavy-duty truck brake applications where proper brake linkage adjustment matters.
It’s a small part, but if the clevis wears out or gets damaged, brake adjustment and pushrod alignment can suffer. That can create uneven braking, excess play, or improper brake stroke.
Brake linkage parts like this take constant stress from daily braking cycles and road vibration.
What the Part Does
The clevis attaches to the threaded brake chamber pushrod and connects it to the slack adjuster arm.
This connection transfers force from the brake chamber into the braking system. Proper clevis adjustment helps maintain correct brake stroke and balanced braking performance.
A worn clevis can introduce looseness into the linkage and affect brake response.
Common Problems This Part Solves
A worn or damaged clevis may cause:
- Excess play in the brake linkage
- Uneven brake adjustment
- Brake stroke issues
- Worn clevis pin holes
- Difficulty maintaining proper adjustment
Corrosion and lack of lubrication often speed up wear in the pin area.
Why Replacement Matters
Brake linkage components work together as a system. If the clevis becomes worn or loose, brake adjustment can drift and affect stopping performance.
Replacing worn linkage parts helps maintain proper brake geometry and keeps the system operating safely.
Since the clevis is inexpensive, many shops replace it during brake chamber or slack adjuster service rather than risking future problems.
Compatibility and Fitment
This 5/8 clevis replaces OEM part number AS3000. Always verify pushrod thread size and brake configuration before ordering.
Proper thread engagement and adjustment are important for safe brake operation.
Installation and Service Notes
Installation involves threading the clevis onto the pushrod and adjusting it to proper brake stroke specifications.
After installation, verify pushrod travel and confirm proper slack adjuster adjustment. Clevis pins and retaining hardware should also be inspected during service.
This component pairs directly with the Automatic Slack Adjuster and brake chamber assembly.
Use Case
Commonly used during brake chamber replacement, brake adjustment repairs, and routine air brake maintenance work.
