The following general information is web-sourced and may contain variances from the subject unit:
The 1990 Mack CH613 6×4 Tractor Semi is a quintessential example of a classic, reliable American workhorse from a golden era of mechanical truck engineering. Launched in 1988 to replace the legendary R-Model, the CH series (specifically the CH613) became a staple for over-the-road regional hauling and heavy-duty vocational work.
Your specific configuration features a highly sought-after, pre-electronic powertrain known for its bulletproof reliability and long service life.
Vehicle Profile & Capabilities
- Model Line: The "CH" stands for Corporate Highway. The "6" indicates the class/series, and "13" traditionally reflects its basic application configuration and bumper-to-back-of-cab (BBC) footprint.
- Chassis Configuration (6×4): It is a tandem-drive axle tractor (three axles total, with both rear axles receiving power). This offers optimal traction for heavy highway hauling, dump trailers, or lowboys.
- The Era of Reliability: Being a 1990 model, this truck bypasses almost all complex electronic engine controls and modern emissions systems (such as DPF/DEF). This makes it vastly simpler and significantly cheaper to maintain, and repair compared to newer semi-trucks.
2. Maxitorque Extended Range 12-Speed Splitter Transmission
The Mack Maxitorque 12-speed manual is highly regarded by pure Mack enthusiasts.
- How it Works: It uses a multi-speed design consisting of a standard main gearbox pattern multiplied by an air-actuated splitter system (usually operated by a switch or button on the dash or shifter knob).
- The Perks: Drivers love this transmission because it requires minimal shifting across the main gates once you are up to speed. It offers a deep low-low gear for starting heavy loads on inclines and a massive array of reverse speeds, making it excellent for tight maneuvering and backing up dump trailers.
Common Characteristics & Community Consensus
- Ride Quality: If equipped with the traditional Mack "Camelback" leaf-spring suspension, it will handle extreme weights beautifully but is famously known to "ride like a tank" when empty. If it has the optional air-ride suspension, it provides a much smoother, modern highway ride.
- Cab Comfort: The CH series introduced a vastly more aerodynamic fiberglass hood and a spacious cab compared to the tight, boxy R-models. It focused heavily on driver visibility and reduced interior noise
