CAT 095-9038 SPRING RET

CAT 095-9038 Recoil Spring

The CAT 095-9038 is a main return/buffer spring for the track tensioning mechanism of the 760GT heavy-duty tracked chassis. It is a large-diameter cylindrical helical compression spring, suitable for Caterpillar 349/352/374/395 excavators, 982/988 loaders, and other heavy-duty models. It is a core elastic component for track tensioning, impact buffering, and automatic return.

Core Parameters

Item Details
Part Number CAT 095-9038 (0959038)

Component Name Return Spring / Recoil Buffer Spring

Compatible Platform 760GT Track Chassis Tensioning Mechanism

Material High-carbon alloy spring steel (Cr-Mn-Si series), integral quenching + medium-temperature tempering, high elastic limit, fatigue resistance

Structure Equal pitch cylindrical compression helical spring, both ends ground flat and subjected to strong pressure fixing treatment

Functional Positioning Provides track tension preload, absorbs walking impact load, automatically resets after collision, and forms an elastic buffer unit with 095-8076 spring base and 095-8510 retainer

Assembly Relationship and Installation Position Installed in the spring cavity of the tensioning mechanism, one end abuts against 095-8076 spring base, and the other end abuts against 095-8510 spring retainer, and is axially preloaded during assembly.

Collaborating Components: 095-8076 Spring Base, 095-8510 Fixer, 095-7947 ​​Buckle, Tensioning Cylinder Piston/Slipper Assembly.

Operating Logic: Track impact → Spring compression absorbs energy → Impact disappears → Spring rebounds and resets, maintaining standard track tension.

Installation and Maintenance Points:

Assembly: Must be installed in a pre-compressed state, ensuring both ends are properly aligned with the base/fixer, without misalignment or lateral bending.

Inspection Cycle: Every 1000 hours under normal operating conditions; shortened to 500 hours under mining/crushing conditions.

Replacement Criteria:
Free length attenuation > 3%
Appearance of cracks, rust pits, permanent deformation, uneven pitch
Significant decrease in elasticity leading to insufficient track tension and frequent loosening.

Prohibitions: Do not heat or weld the springs; do not use springs of non-original specifications to avoid abnormal tension and impact breakage.
