CAT 095-5848 RETAINER

CAT 095-5848 (0955848) is a track tensioner retainer for Caterpillar 400GT track chassis. It is compatible with heavy-duty models such as the 349/352/374/395 excavators and 982/988 loaders. It works in conjunction with the 095-5581 spring base, 095-5456 inner retaining ring, and 095-3812 track link. Its core function is to lock the track tension spring assembly, preventing axial movement and ensuring stable transmission of tension force. It is a key locking component of the track tensioning mechanism.

Item Details
Part Model CAT 095-5848 (0955848) Track Recoil Spring Retainer

Type: Track tensioning mechanism ring locking part, flange with bolt holes, compatible with 400GT track tensioning system, matches 095-5581 spring base and 095-5456 inner retaining ring

Material: 42CrMo alloy steel, integral forging + tempering heat treatment (hardness HRC30-35), surface Caterpillar yellow primer + wear-resistant coating, resistant to heavy-duty impact, fatigue resistance, and corrosion resistance

Key Dimensions: Outer diameter approx. 240-260mm, inner diameter approx. 120-130mm, thickness approx. 22-28mm, flange with 8 M18 bolt holes, compatible with 095-5581 spring base mounting surface

Compatible Models: CAT 400GT tracked chassis equipment, including excavators (349, 352, 374, 395), loaders (982, 988, etc.).

Functional Positioning: Installed on the 095-5581 spring base flange, secured with bolts, it works in conjunction with the inner retaining ring to lock the tension spring, limiting axial movement, transmitting tension force, and ensuring the stability of the track tensioning mechanism.

Adaptation and Application:
Adapted Part: Core locking component of the track tensioning mechanism, installed on the 095-5581 spring base flange. The inner side mates with the 095-5456 inner retaining ring, and the outer side connects to the track connecting rod via bolts, working together to fix the tension spring assembly and prevent axial movement of components.

Application Scenarios: Heavy-duty working conditions such as mining and infrastructure construction, bearing the impact and vibration of track movement, preventing abnormal wear of chain links and track rollers caused by excessively loose/tight tracks, and ensuring the stability of the walking system.

Core Functions: Locks the tension spring, provides axial positioning, transmits tension force, works in conjunction with the spring base and inner retaining ring, buffers impacts, protects chassis components, and extends the life of the track system.

Installation and Maintenance Points

Installation: Clean the connecting surfaces and tighten the bolts to the original torque of 400-450 N·m; check the fit with the 095-5581 base and 095-5456 inner retaining ring to ensure no gaps or looseness.

Maintenance Cycle: Check for deformation, cracks, and bolt torque of the retainer every 500 hours. In harsh working conditions such as mining, this period can be shortened to 200 hours.

Replacement Standard: Replace the track if cracks, deformation, bolt hole wear, or failure to fit the base/inner retaining ring are found. Original parts are preferred to avoid tension failure and track misalignment due to size/strength issues.
