Multiquip 42759 Silicone Boot 45DEG 1.75" x 1.75" CAC - OEM Replacement Part

This 45-degree silicone boot provides a critical flexible connection in the charge air cooler (CAC) system on Multiquip riding trowels, protecting against vibration damage and maintaining sealed airflow between CAC components. The 1.75" x 1.75" configuration ensures proper fitment on compatible models during engine system maintenance or repair.

Designed for heavy-duty trowel applications, this silicone boot withstands the extreme vibration and temperature fluctuations inherent in concrete finishing equipment. The 45-degree angle allows proper routing of charge air cooler piping while accommodating the mechanical movements during operation, including blade pitch adjustments and machine calibration procedures. When performing major service or machine setup procedures—such as blade leading edge height calibration where cylinders are fully extended—intact CAC components ensure consistent engine performance and prevent air leaks that could compromise power output.
