CAT 526-0040 BEARING-SLV-GD

CAT 526-0040 (5260040) YM mudguard housing is a metal support housing for the rear mudguard of Caterpillar wheel loaders (YM is a quality designation, representing a high-compatibility replacement with performance identical to the original). It is used to secure the mudguard body, protect against mud/gravel splashed from the tires, and protect the vehicle body and hydraulic lines. The following are the key details:

Key Technical Parameters
Item Details

Key Dimensions: Length 520 mm, Width 380 mm, Height 120 mm, 6 mounting holes (12mm diameter) mm, hole spacing 180 mm × 260 mm, compatible with M12 × 1.75 bolts), compatible mudguard body size 500 × 360 mm
Single weight approx. 6.2 kg (13.67 lb)
Compatible models: CAT 930M/938M/950M wheel loaders (rear mudguard mounting position), used to fix the mudguard, protect against tire debris, and protect hydraulic lines and vehicle body paint.
Operating compatibility: Operating temperature -30℃ to +80℃, impact load resistance 8 kN, protection angle 120°, compatible with original factory/YM quality mudguard rubber body
Core functions and structural features:
Integrated support and protection: As a metal support frame for the mudguard body, it provides rigid fixation while blocking gravel impacts, protecting rear hydraulic lines, wiring harnesses, and vehicle body.

Precise Installation and Positioning: Six mounting holes are precisely aligned with the rear frame holes of the loader, ensuring no loosening after bolt tightening, and perfectly suited for the installation and positioning of the rear fender body.

Corrosion and Durability: The powder-coated surface is resistant to acids, alkalis, and UV rays, suitable for dusty and humid working conditions, extending service life.

YM Quality Assurance: YM marking parts are consistent with the original in material, size, and coating process, meeting CAT standards for compatibility and durability, offering better value for money.

Installation and Maintenance Points
Installation Specifications: Clean the frame mounting surface, ensuring it is free of rust, oil, and burrs. Ensure the shell fits snugly against the frame with a gap ≤1 mm.

Tighten symmetrically with M12×1.75 bolts (8.8 grade) at a torque of 45–50 N・m to avoid localized stress that could deform the shell.

After installation, check the fit between the fender body and the shell; ensure no warping at the edges to guarantee effective protection.

Maintenance Recommendations:

Inspect every 500 working hours: Check for coating peeling, housing deformation/cracks, and loose bolts. Repair or replace any issues promptly.

When cleaning, avoid spraying high-pressure water directly onto the coating edges to prevent coating peeling.

When replacing parts, prioritize YM quality parts of the same specifications or original parts, ensuring proper mounting hole alignment and compatibility.
