The Multiquip RG60446 is a genuine OEM Turbo Charge 3 Bolt 4020TF STH-55 designed for the Multiquip STH55 series equipment. As a direct OEM replacement, RG60446 ensures the correct mounting configuration and turbocharger specification for this application, so your machine returns to full operating condition without guesswork. Sourced directly through Multiquip's authorized parts network, this component is the same part your machine left the factory with. Confirm your model code is STH55 before ordering to ensure compatibility.
Key Features
- Genuine OEM Turbocharger Integrity — Manufactured to the exact boost and flow specifications required by the STH55 powertrain, ensuring correct exhaust-driven compression output.
- 3-Bolt Mounting Configuration — The three-bolt flange pattern matches the STH55 exhaust manifold directly, allowing straightforward installation without adapter hardware.
- 4020TF Turbo Specification — Matches the OEM-specified 4020TF turbocharger model for the STH55, preserving the engine's designed power output and fuel efficiency.
- STH55 Series Fitment — Engineered specifically for the Multiquip STH55, eliminating compatibility concerns common with non-OEM substitutes.
- Engine Protection Through Correct Boost Delivery — A worn or failed turbocharger leads to loss of power, excessive smoke, and accelerated engine wear; replacing with the correct OEM unit restores proper combustion and protects the engine long-term.
A turbocharger uses exhaust gases leaving the engine to spin a turbine, which in turn drives a compressor wheel that forces additional air into the engine's intake. This increased air density allows more fuel to be burned per cycle, producing significantly more power from the same engine displacement. When a turbocharger begins to fail — through bearing wear, shaft imbalance, or compressor blade damage — the engine loses boost pressure, resulting in reduced power output, increased fuel consumption, and the risk of oil contamination entering the intake or exhaust system. Replacing a failed unit with the correct OEM part, such as the Multiquip RG60446, restores the precise boost characteristics the STH55 was engineered to operate with.
