Support both inspection advice and professional parts supply.
If you notice clicking or grinding sounds around the 45x50x30 pivot, it usually indicates the bushing surface has worn beyond limits. Check for clearance. If vibration persists, replace with an OEM-standard tri-metal structure bushing immediately to prevent damage to the main shaft.
Overheating is often caused by poor lubrication or high-friction materials. Our replacements feature optimized internal oil grooves to ensure constant cooling. Always verify that the pin matches the 45mm internal diameter exactly.
