The IDLER is an important part of the walking system of large-scale construction machinery such as excavators. It is installed on the track to guide the track. Its main function is to guide the correct winding of the track. Adjust the tension of the track, so the guide wheel is not only the guide wheel of the track, but also the tensioner in the tensioner.
How to replace the guide wheel of the excavator:
- Remove the crawler belt of the excavator first.
Remove a one-way valve at the grease nipple, release the butter inside, push the guide wheel in with a bucket, make the track as loose as possible, and remove the track pin if the excavator used is below 150 If it is more than 150, use a bucket to hook off the track. Remember to remove the single valve, otherwise it will be difficult to remove the track, let alone install it.
2. Install IDLER.
the IDLER installation is the same as the general wheel installation method. Use a jack to support the excavator, and then use a screwdriver to unscrew the screws. After removing them, install new wheels and apply lubricating oil to complete the installation.
Use a grease gun to inject butter into the grease cylinder through the grease nozzle, make the piston stretch out to push the tension spring, and move the guide wheel to the left to tighten the track. The tension spring has an appropriate stroke. When the tension force is too large, the spring is compressed It acts as a buffer; after the excessive tension disappears, the compressed spring pushes the guide wheel to its original position.
This can ensure sliding along the track frame to change the wheelbase, ensure the disassembly and assembly of the track, reduce the impact of the walking process, and avoid the derailment of the rail chain. The cause of damage to the guide wheel assembly is mainly due to poor lubrication of the guide wheel shaft.
The above is the replacement method of the excavator undercarriage parts for the IDLER, I hope it will be helpful to everyone. If you want to know more about excavator accessories, you can pay attention to our company website: www.qzhdm.com or email me(Email: hongda04@qzhdm.com),thanks a lot
