Sanden F691015111 SD7H15 A/C Compressor Assembly

The Sanden SD7H15 Super Heavy Duty compressor platform serves as the OEM standard for PACCAR HVAC systems. This unit features a 7-cylinder swash plate design optimized for high-displacement refrigerant circulation in Class 8 sleeper cab applications. The clutch assembly integrates a 125 mm diameter pulley with 6-groove poly-V belt interface driven by a 12 V coil. The rear head configuration utilizes a special fitting style with integrated pressure relief valve and a 2-pin Metripack 150 electrical connector. Factory oil charge requires PAG 100 viscosity at approximately 300 cc. The compressor mounts in a direct-mount tangent pattern compatible with Cummins ISX15 and PACCAR MX-13 engine accessory drives. Service replacement requires verification of clutch air gap (0.35-0.65 mm) and system flush per SAE J2788 standards. Cross-reference interchangeability covers Sanden service numbers 4106, 4859, 4289, 4577, and 4589. PACCAR OEM part numbers include F69-1015-111, F691015111, F69-1028-111, F691028111, F69-1013, RF99962605, and SN4577. Aftermarket equivalents include Four Seasons 98500, Air Source 54106, and various private-label SKUs. Installation mandates O-ring replacement at all hose connections and torque specification adherence for mounting fasteners (typically 24-28 Nm).
