195-30-68820 CYLINDER is a core idler cushion cylinder component specially designed for Komatsu D375 series crawler dozers. As a key part of the track tensioning and buffer system, this cylinder undertakes track tension adjustment and impact buffering functions during heavy-duty operation. It effectively absorbs strong vibration and impact generated during mining, earthmoving and foundation compaction, maintaining stable track tension and ensuring flexible, stable walking performance of the D375 dozer in harsh working conditions.

In-stock products are delivered within 3-7 working days. For out-of-stock items, we will inform the exact production cycle and lead time before order confirmation.
Q4: What does the warranty cover?
6-month official warranty covers manufacturing quality defects. Damage caused by improper installation, overloaded operation, man-made collision and normal wear and tear is not included in the warranty scope.
Q5: How to get a formal quotation?
Please provide the part number, purchase quantity and delivery address, our sales team will send you a detailed formal quotation within 24 hours.
Installation Guide
1. Completely shut down the Komatsu D375 dozer, cut off the power and release the residual hydraulic pressure of the walking system to ensure construction safety.
2. Clean the installation position of the idler cylinder, remove surface dust, mud, old oil dirt and residual sundries to avoid impurities entering the hydraulic system.
3. Inspect the new cylinder carefully to confirm no deformation, seal damage or transportation scratches.
4. Align the cylinder with the installation interface accurately, adjust the track tension moderately, and fasten the fixing bolts according to the standard torque to ensure stable installation.
5. After installation, perform idle test run and walking test, check for oil leakage and abnormal vibration, and confirm the track tensioning and buffering functions work normally.
Maintenance Tips
– Regularly check the cylinder sealing surface and pipeline joints during daily maintenance to eliminate hidden dangers of oil leakage in advance.
– Keep the cylinder surface clean, avoid long-term adhesion of mud and corrosive substances to prevent cylinder body corrosion and seal aging.
– Avoid long-term overloaded walking and frequent sharp turning of the equipment to reduce instantaneous impact load on the cylinder.
– When replacing the cylinder, check the matching track idler, seal and hydraulic pipeline synchronously, and replace the worn supporting parts together to ensure overall system stability.
