Background
An operator asked for advice about maintaining and troubleshooting an Extec C12 jaw crusher. They were experiencing a few mechanical issues and wanted insights from others who have run the same machine.
Common Issues
Several users shared that the Extec C12 is known for certain wear points and common failures. Frequent problems include the jaw plates wearing out quickly, the conveyor drive needing attention, and the hydraulic system sometimes developing leaks.
One operator mentioned that checking the jaw tension regularly is crucial to prevent uneven wear or damage to the toggle plate. Another suggested keeping a close eye on the bearings, as they can fail if not greased and monitored properly.
Hydraulic System Tips
Hydraulic leaks were a recurring topic. It was recommended to regularly check all hoses and fittings and replace any that show signs of wear before they fail. One tip was to keep spare hoses on hand to minimize downtime.
Electrical and Control Issues
Some Extec C12 units have electrical control issues, particularly with the wiring harness and connections. Users advised keeping all connections clean and dry and carrying spare relays and fuses.
Parts Availability
A few operators stressed the importance of having a good local parts supplier, as certain Extec components can be hard to find or have long lead times. Keeping key spares like jaw plates, belts, and filters on hand helps reduce unexpected downtime.
General Advice
Regular inspections and preventive maintenance were emphasized as the best way to keep the machine running well. Following the manual for lubrication schedules and daily checks is important. It was also suggested to keep the crusher clean, especially around the jaw area, to prevent buildup that can lead to blockages.
Conclusion
The Extec C12 jaw crusher is a solid machine when maintained properly. Operators who watch for common wear points, stock critical spare parts, and stick to a good maintenance routine can avoid many typical problems and keep the crusher producing reliably.
