Bypass Drive Belt Roller 1025400FE130
,JAC N56 Sunray SOLLERS Atlant 2.7D roller
,OEM 8040998660 drive belt roller
The 1st Bypass Drive Belt Roller (Lower Idler Pulley) with OEM number 1025400FE130 is a verified direct-fit replacement for JAC N56, JAC Sunray, and SOLLERS Atlant trucks equipped with the 4DE1-1D 2.7D diesel engine (Euro 5). This lower bypass idler pulley guides the accessory drive belt along the correct routing path, maintaining proper tension and preventing belt slip or misalignment that can lead to auxiliary system failure.
- Material Verified: High-strength aluminum alloy / composite pulley body with anti-corrosion coating — verified by metallurgical and salt spray testing across 50+ production batches.
- Dimensional Accuracy: Outer diameter 70mm, width 36.5mm — verified by precision caliper on 100% of finished goods. Direct OEM fitment, no modification required.
- Bearing Verified: Sealed radial ball bearing (2RS, double rubber seal) — pre-lubricated, dust-proof, maintenance-free. Verified by noise and rotation torque testing.
- Installation Success Rate: 99.3% direct bolt-on fitment — confirmed across 280+ accessory drive repair orders with zero fitment returns.
- OEM Cross-Reference Verified: Replaces JAC part number 1025400FE130 and OE cross-reference 8040998660.
- Squealing or chirping noise from the accessory drive belt area, especially at cold start or under load.
- Visible belt wear, glazing, or fraying on the edge nearest the idler pulley.
- Pulley wobble or roughness when spun by hand (bearing failure).
- Belt misalignment or slipping off the pulley groove.
