CAT 095-9760 SEAT SPRING

The CAT 095-9760 (0959760) is a spring base for the track tensioner cylinder of the 760GT tracked chassis. It is a cup-shaped cast steel structure with a central locating hole, compatible with models such as the 349/352/374/395 excavators and 982/988 loaders. Installed inside the tensioner cylinder, it supports the 095-9732 main compression spring, positions the 095-9380 spring seat, and works in conjunction with the 095-9643/095-9665 retainer to ensure spring coaxiality and uniform force distribution. Suitable for heavy-duty, high-frequency vibration conditions, it protects the cylinder inner wall and the 095-8931 Cat® bearing.

Item Details
Part Model CAT 095-9760 (0959760) Spring Base (760GT Track Tensioning Cylinder Dedicated)

Structure Type Cup-shaped with center positioning hole + inner ring step + outer ring flange. The center hole is adapted to the piston rod guide sleeve of the tensioning cylinder. The inner ring step positions the 095-9380 spring seat. The outer ring flange is fixed to the inside of the cylinder body with bolts.

Material QT500-7 ductile iron, precision casting + surface rust prevention treatment, tensile strength ≥500MPa, yield strength ≥320MPa, suitable for working conditions from -40℃ to 150℃, impact and deformation resistant.

Key Dimensions Inner diameter approx. 146-150mm (adapts to 095-9732 spring outer diameter), center positioning hole diameter approx. 85-90mm (adapts to piston rod guide sleeve), inner ring step height approx. 10-12mm, flange thickness approx. 15-18mm, total height approximately 45-50mm, clearance between the inner wall of the cylinder and the frame ≤0.3mm. Compatible with CAT 349, 352, 374, 395 excavators; 982, 988 loaders (760GT tracked chassis configuration).

Functional Positioning: Supports the 095-9732 main compression spring, positions the 095-9380 spring seat, limits spring radial offset, distributes axial load from the spring to the cylinder body, protects the cylinder inner wall and guide sleeve, and ensures the stability of the tensioning system.

Application and Fit:
Installation Position: Inside the track tensioning cylinder, fixed with outer flange bolts. The piston rod guide sleeve is fitted into the center positioning hole. The inner ring step supports the 095-9380 spring seat. The 095-9732 spring is installed between the spring seat and the 095-9643/095-9665 retainer, forming a closed-loop load transfer system. Application Scenarios: Suitable for heavy-duty operations such as mining stripping, rock crushing, and tunnel excavation. It withstands high-frequency impacts and alternating loads from the 095-9732 spring, preventing spring eccentricity from causing scratches on the cylinder inner wall and wear on the guide sleeve. It is suitable for high-intensity working environments.

Core Functions: Positions the spring seat and spring, distributes axial loads, limits radial spring offset, protects critical cylinder components, maintains stable track tension, and reduces the risk of tensioning system failure.
