CAT 095-8510 RETAINER

CAT 095-8510 (0958510) is a track tension cylinder spring retainer for the 760GT tracked chassis. It is a ring-shaped stepped positioning component used to lock the axial position of the buffer spring and the 095-8076 spring base. It is compatible with models such as the 395/374/352/349 excavators and 988/982 loaders, and works in conjunction with the 095-7947 ​​retainer and the 095-8076 spring base to ensure stable operation of the track tensioning system (Cat® Parts).

Compatible Models CAT 349, 352, 374, 395 excavators; 982, 988 Loader (760GT Tracked Chassis Configuration)

Functional Positioning: Locks the axial position of the buffer spring and spring base, transmits the spring force during track tensioning/buffering, prevents radial offset and circumferential rotation of the spring and base, protects the tensioning cylinder seals and guide cylinder, and works with the 095-7947 ​​retaining ring to lock the axial position.

Adaptation and Application:

Installation Location: Inside the guide cylinder of the track tensioning cylinder, located outside the 095-8076 spring base. The positioning key is embedded in the keyway of the guide cylinder, the stepped surface fits against the end face of the spring base, and the outer side is locked by the 095-7947 ​​retaining ring to prevent axial movement of the spring and base.

Application Scenarios: Heavy-duty, high-frequency impact conditions such as mining and infrastructure construction, bearing the axial load and vibration of the spring, adapting to the dynamic load during track tensioning/buffering, preventing damage to the cylinder seals, track tension fluctuations, and track deviation caused by spring and base movement.

Core Functions: Axial positioning buffer spring and spring base transmit tension force. Working in conjunction with the retainer and spring base, they ensure the installation accuracy and stability of tensioning system components, extending the service life of components such as cylinders and springs (Cat® Parts).

Installation and Maintenance Points

Installation: Clean the guide tube, retainer, spring base, and retainer mounting surfaces to remove oil, rust, and impurities. Check the locating key and keyway for damage.

Insert the retainer into the guide tube, aligning the locating key with the keyway and the stepped surface facing the spring base. Insert the 095-8076 spring base and buffer spring, ensuring a tight fit. Install the 095-7947 ​​retainer to lock the axial position of the retainer, checking for looseness or misalignment.

Start the machine to test the extension and retraction of the tensioning cylinder. Check for abnormal noise from the retainer and stable tension force.

Maintenance Cycle: Under standard operating conditions, check for retainer wear, locating key deformation, and clearance with the spring/retainer every 1000 hours. For mining conditions, shorten this to 500 hours. Address any abnormalities immediately.

Replacement criteria: Replacement is required if the wear of the retainer step is >1.2mm, the positioning key is deformed/broken, there are surface cracks, the clearance between the retainer and the spring is >0.6mm, or the spring cannot be positioned after installation. Original parts should be given priority to avoid dimensional deviations that could cause spring misalignment or damage to the hydraulic cylinder.
