Installation Guide
Clean the bore and remove any old bushing residue, rust or debris before installation.
Inspect the pin for wear or scoring; replace the pin if damaged to avoid premature bushing wear.
Align the new bushing with the bore and press it into place using a proper press tool – do not hammer directly.
Check that the bushing is fully seated and the pin rotates freely without excessive play.
Lubricate the pin joint with the recommended grease before returning the machine to service.
Maintenance Tips
Inspect pin and bushing play every 500 operating hours; lift the attachment and check for free play by hand.
Re-grease all pivot joints at the recommended intervals to keep the bushing lubricated.
Replace the bushing immediately if play exceeds tolerance or bore wear is visible, to protect pins and linkage.
Check adjacent components for wear when replacing a bushing, and order matching pins if needed.
