Multiquip 42742 Pipe Assembly Hot Side CAC

The Multiquip 42742 Pipe Assembly Hot Side CAC is a genuine OEM component designed for the HTX6H heavy-duty hydrostatic ride-on power trowel. As a factory-sourced part, it meets the original design tolerances required to maintain proper charge air cooling performance on the HTX6H. Sourced directly through an authorized Multiquip dealer, this assembly ensures the correct connection geometry and flow path are preserved when servicing or replacing a damaged hot-side CAC pipe.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specs, ensuring the correct wall thickness, bend angles, and port sizing for proper charge air flow on turbocharged trowel engines.
• Direct-Fit Replacement — Engineered to connect to the existing CAC inlet and outlet ports on the HTX6H without rework or adapter fittings, allowing a straightforward swap during service.
• Confirmed HTX6H Fitment — Verified for the Multiquip HTX6H heavy-duty hydrostatic ride-on power trowel. Always confirm your model and serial number before ordering.
• Charge Air Integrity — A correctly functioning hot-side CAC pipe delivers compressed, pre-cooled air efficiently to the charge air cooler. A cracked or leaking pipe causes boost loss, elevated intake temps, and reduced engine output during finishing operations.
• Authorized Source — Sold by DHS Equipment, an authorized Multiquip parts dealer, so you receive a verified part backed by proper sourcing documentation.

The hot-side CAC pipe carries compressed air from the turbocharger outlet to the charge air cooler (CAC) inlet — the hottest and highest-pressure section of the induction system. Its role is to deliver that air to the cooler so intake temperatures are reduced before the air enters the engine, improving combustion efficiency and protecting the motor under sustained load. When this pipe cracks, loosens, or collapses, boost pressure bleeds off, intake air temperatures rise, and the engine loses power — symptoms that become most noticeable during heavy finishing passes on large slabs.
