Keep the camshaft turning in step with the crankshaft with the Cloyes Timing Chain C494, a single-row, inverted-tooth chain made from pre-stressed, heat-treated steel. It fits many vehicles, among them the 1975-1979 Ford F-150 5.9L / 6.4L / 6.6L, the 1968-1982 Ford F-250 5.8L / 5.9L / 6.4L / 6.6L and the 1967-1973 Ford Mustang 5.8L / 6.4L / 7.0L. See the "Vehicles it fits" section for the full list and the engine for each application.
Cloyes has built automotive timing systems since 1921. This engine timing chain links the crankshaft and camshaft and is designed to keep valve timing synchronized with the pistons. Cloyes engineers it for a close chain-to-sprocket tooth fit.
- Pre-stressed, heat-treated steel: the steel is treated for increased strength and wear resistance.
- Precision pitch control: the chain is manufactured to a 0.5 in (12.7 mm) pitch for proper chain-to-sprocket fit. This helps reduce noise and fatigue and helps maintain accurate timing.
- OE-level fit and function: the chain was designed in the USA and is made with premium materials for smooth installation. Each part is tested for function, fitment and durability.
- Warranty: the chain is backed by a Limited Lifetime Warranty and Cloyes technical support.
Specifications: inverted-tooth chain; single row; 48 links; 0.5 in (12.7 mm) pitch; chain length 12.13 in (307.98 mm); chain width 0.72 in (18.29 mm). The chain has no timing marks. The listed applications use one chain. Country of origin: China.
This listing is the timing chain alone. During timing service, Cloyes recommends replacing the related timing components along with the chain, such as the sprockets and any tensioners and guides the engine uses. Follow the vehicle service information for timing alignment and installation.
Frequently Asked Questions
Is the C494 the right 1975-1979 Ford F-150 timing chain for the 5.9L / 6.4L / 6.6L?
It is listed for the 1975-1979 Ford F-150 5.9L / 6.4L / 6.6L and the 1968-1982 Ford F-250 5.8L / 5.9L / 6.4L / 6.6L. Check the "Vehicles it fits" section to confirm your year and engine.
Can I use this as a timing chain for the 1967-1973 Ford Mustang 5.8L / 6.4L / 7.0L?
It is listed for the 1967-1973 Ford Mustang 5.8L / 6.4L / 7.0L. Check the "Vehicles it fits" section for the engines covered in each year.
What does a timing chain do?
It connects the crankshaft to the camshaft so the valves open and close in time with the pistons. This Cloyes chain is a single-row, inverted-tooth design with a 0.5 in pitch.
What signs suggest a timing chain may need replacing?
Common signs include a rattle from the front of the engine, especially at startup, and rough running or hard starting if the timing has slipped. Diagnose the cause before replacing parts.
What comes with the C494, and should I replace other parts?
This listing is the timing chain only. During timing service, Cloyes recommends replacing the related timing components along with the chain, such as the sprockets and any tensioners and guides the engine uses.
