CAT 095-7726 RETAINER

CAT 095-7726 (0957726) is a slip shoe retainer for the track tensioning cylinder of the 760GT tracked chassis. It works in conjunction with the 095-7124 slip shoe, 095-7577 piston retainer, and 095-6848 inner retainer ring to lock the radial position of the slip shoe and the tensioning cylinder guide cylinder, preventing circumferential rotation and radial displacement of the slip shoe during track tensioning/buffering. It is compatible with Cat® Parts for 760GT tracked chassis models such as the 395/374/349 excavators and 988/982 loaders.

Item Details
Part Model CAT 095-7726 (0957726) Slip Shoe Retainer (for 760GT track tension cylinder slippers)

Type: Slipper circumferential positioning retainer, ring structure, outer ring with anti-rotation teeth, inner ring with radial positioning groove, compatible with 760GT slipper outer diameter and guide cylinder inner diameter

Material: 42CrMo alloy steel, tempered + surface nitrided, hardness HRC38-42, wear-resistant, impact-resistant, suitable for operating conditions from -40℃ to 120℃

Key Dimensions: Inner diameter matches slipper outer diameter (approx. 150-160mm), thickness approx. 18-22mm, anti-rotation tooth height approx. 8-10mm, radial positioning groove depth approx. 6-8mm, circumferential clearance ≤0.1mm after installation

Compatible Models: CAT 349, 352, 374, 395 Excavators; 982, 988 loaders (760GT tracked chassis configuration)

Functional Positioning: Locks the circumferential and radial positions of the slipper, preventing slipper rotation and offset during tensioning/buffering, ensuring the sliding accuracy between the slipper and the guide cylinder, and enhancing the overall stability of the tensioning mechanism in conjunction with the 095-7577 retainer.

Adaptation and Application:

Installation Location: At the front end of the guide cylinder of the track tensioning cylinder, in the gap between the slipper and the guide cylinder, embedded in the annular groove on the inner wall of the guide cylinder. The anti-rotation locking teeth engage with the locking groove on the outer ring of the slipper, and the radial positioning groove engages with the positioning protrusion of the slipper, doubly locking the circumferential rotation and radial displacement of the slipper.

Application Scenarios: Heavy-duty, high-frequency impact conditions such as mining and infrastructure construction, bearing the radial load and circumferential torque of the slipper’s reciprocating motion, preventing slipper rotation from causing wear on the inner wall of the guide cylinder and damage to the seals, and avoiding track tension fluctuations and track deviation.

Core Functions: Circumferential anti-rotation and radial positioning ensure the coaxiality and sliding accuracy of the slipper and guide cylinder, prevent abnormal wear of the slipper, and extend the service life of the tension cylinder and slipper.

Installation and Maintenance Points

Installation: Clean the guide cylinder groove, retainer, and slipper positioning surface, removing oil, rust, and impurities, ensuring the locking teeth and grooves are undamaged.

Embed the retainer into the guide cylinder groove, ensuring the anti-rotation locking teeth are fully engaged in the slipper groove, and the radial positioning groove precisely matches the slipper protrusion. Tighten with bolts (if included) to grade 10.9 standard, torque 30-40 N·m.

After installation, check the slipper’s rotational flexibility to ensure no jamming. Start the machine to test the extension and retraction of the tension cylinder, checking the retainer for looseness and abnormal noise.

Maintenance Cycle: Under standard operating conditions, check retainer wear, locking tooth deformation, and bolt tightening every 1000 hours; for mining conditions, shorten to 500 hours. Replace immediately if locking teeth are found to be worn/deformed.

Replacement criteria: Replacement is required when the wear of the locking teeth is greater than 0.5mm, the teeth are deformed or broken, the radial positioning groove wear causes a gap greater than 0.2mm, or the slip shoe cannot be locked after installation. Original parts are preferred to avoid dimensional deviations that could cause slip shoe rotation, guide cylinder wear, or seal failure.
