Multiquip 42739 Hot Side CAC Pipe

The Multiquip 42739 Hot Side CAC Pipe is a genuine OEM component designed for HTX6H and STX6H hydrostatic ride-on power trowels. As a direct Multiquip OEM part, it is manufactured to the exact specifications of the original component, ensuring a correct, trouble-free installation. This pipe is confirmed to fit the HTX6H heavy-duty hydrostatic series and the STX6H super-sized hydrostatic series trowels.

Key Features

• Genuine OEM Construction: — Formed to the precise dimensions and material grade of the original pipe, maintaining correct charge-air flow characteristics through the CAC circuit.
• Direct-Fit Replacement: — Matches the original routing, end fittings, and mounting points on HTX6H and STX6H trowels for a straightforward swap with no reworking of surrounding components.
• Confirmed Fitment: — Verified for the HTX6H heavy-duty hydrostatic and STX6H super-sized hydrostatic ride-on power trowel series.
• Charge-Air Integrity: — Maintains a sealed, pressure-rated flow path on the hot side of the charge air cooler, supporting consistent engine output and preventing power loss caused by boost leaks.
• Engine Protection: — A cracked or deteriorated hot side pipe allows hot, pressurized charge air to escape before reaching the CAC core, elevating intake temperatures and increasing the risk of detonation — replacing it promptly protects the engine from heat-related wear.

The hot side CAC pipe carries compressed, heated air from the turbocharger outlet to the charge air cooler (CAC) inlet. The charge air cooler then reduces that air temperature before it enters the engine, allowing a denser air charge and more efficient combustion. When this pipe cracks, collapses, or loses a seal at either end, boost pressure escapes, intake temperatures rise, and the engine loses power and efficiency — making it one of the more consequential pipes in the turbocharged engine circuit to keep in good condition.
