CAT 096-4086 ROLLER

CAT 096-4086 (0964086) is a Caterpillar original single-flange guide roller, compatible with the chassis, tracks, or linkage mechanisms of mini excavators/loaders, used for track guidance, load support, and anti-deviation. The following are the precise information for this original part:

Core Parameters and Compatibility Information

Item Details
Part Model: CAT 096-4086 Original single-flange guide roller, weighing approximately 2.8 kg (6.173 lb), compatible with track/rail-type guide structures, providing light to medium load support and anti-deviation functions.

Core Material: Wheel body is made of 42CrMo alloy steel, surface hardened (HRC 58-62), wear-resistant and impact-resistant; built-in double-row needle roller bearings, pre-filled with long-life grease, maintenance-free sealing design, suitable for outdoor dusty and humid conditions.

Key Dimensions: Wheel diameter approximately 80 mm (3.150 in), flange diameter approximately 95 mm. 3.740 in diameter, approximately 25 mm (0.984 in) inner diameter, approximately 65 mm (2.559 in) total length, approximately 50 mm (1.969 in) mounting hole spacing, tolerance grade IT7

Structural Features: Single flange anti-offset design, smooth wheel surface, built-in sealed bearing, elastic retaining rings at both ends for track/rail guidance, preventing derailment, suitable for light to medium load cyclic rolling conditions.

Compatible Models: Compatible with CAT 301.7CR/302.7CR mini excavators, 226B3/236B3 skid steer loaders, and 903C/904C mini loaders for chassis track guide wheel sets and linkage mechanism rail guide parts, ensuring stable operation.

Accessories: Compatible with CAT 196-3215 axle pins, 8T-4120 elastic retaining rings, and CAT 4C-9520… For installation with a punch cylinder, ensure the rollers are flush with the track surface, with a flange clearance of 0.5-1.0 mm between the flange and the side.
Core Functions and Installation Points

Guidance and Support: Provides guidance and light to medium load support for components, preventing track/track misalignment or derailment, reducing friction and wear, ensuring accurate equipment trajectory, and adapting to cyclic rolling conditions.

Installation Specifications: Clean the rollers, mounting shaft, and mounting base surfaces. Check for cracks and deformation in the wheel body, and ensure the bearings are free from jamming or abnormal noise. Ensure the seals are intact and undamaged.

Use cold-pressed bearing installation, ensuring the shaft and roller are coaxial. Secure the elastic retaining ring in place to prevent axial movement.

Tighten the shaft end nut to the torque specified in the machine manual (typically 25-35 N·m). After installation, the rollers should rotate freely without jamming or wobbling.

Maintenance Recommendations: Check roller wear, seals, and rotation every 500-700 working hours. If wheel wear exceeds 0.5 mm or bearing jamming or abnormal noise occurs, immediately replace with original parts.

Use only CAT 096-4086 genuine rollers to avoid non-genuine parts causing poor guidance, track derailment, or component damage due to size/material mismatch.
