3E1907 12V A/C Compressor for Caterpillar

Replace a compressor matching Caterpillar 3E-1907 with this new 12V assembly. The single-groove V-belt pulley and ear-mount body are intended for the original matching A/C installation.

New third-party replacement for the referenced Caterpillar part; not sold as a genuine Caterpillar-branded part.

Specifications

• 12V clutch with two-wire sealed connector
• Single V-belt groove; nominal pulley diameter 138 mm
• Ear-mount housing
• Horizontal O-ring pad connections
• R134a application; clutch dust cover included

Compatibility

Match Caterpillar reference 3E-1907 and the machine serial number before ordering. Check mounting spacing, pulley offset, electrical connector and refrigerant line fittings. This is a 12V compressor, not the 24V 3E-1906 configuration.

Installation

Installation should be performed by a qualified A/C technician. Match the system refrigerant and specified lubricant; verify the compressor oil charge against the equipment service procedure. Replace the receiver/drier and address contamination as required when replacing a failed compressor. Do not assume a factory oil fill matches the entire system requirement.
