Ford Bronco Variable Valve Timing Sprocket
The Variable Valve Timing Sprocket allows the camshaft to hit its marks. Therefore, it increases horsepower by enabling the valves to open and close when they should. Ford Bronco editions use fixed timing marks, but this Variable Valve Timing Sprocket can wander two or three degrees. While that is a small slip, it can rob roughly 50 horsepower, so performance-minded Ford fans prefer a Variable Valve Timing Sprocket set with a degree wheel for accurate settings. There are two basic styles: the earlier fixed-mark gear applied throughout much of the Bronco lineup and the later adjustable Variable Valve Timing Sprocket design that adds multiple keyways, offset bushings, or elongated slots to allow you to advance timing for stronger low-end torque or retard it for extra top-end pull. The present service recommendation from Ford continues to recommend replacement of the Variable Valve Timing Sprocket in conjunction with the chain, tensioners, and guides on overhead cam engines to ensure that every link is synchronized. After the steps, the durable Ford powerplant maintains a smooth idle and the powerful roar that defines a classic Bronco.

Ford Bronco Variable Valve Timing Sprocket Parts Questions & Experts Answers
- Q:How to check the timing chain and Variable Valve Timing Sprocket on the Ford Bronco?Posted by Elio M.A:To check the timing chain on all engines except the 4.9L, remove the timing cover and turn the Crankshaft counterclockwise to take up slack on the left side of the chain. At the mid-point of the right side chain run, push the chain out with a finger while holding a graduated scale against it to establish an initial measurement using the centerline of one link pin as a reference. Then, push the chain in the opposite direction and measure the total deflection from the initial point. Compare this measurement to the specified figure; if excessive, replace the chain and both sprockets, as it is advisable to do so during a major overhaul. For the endplay check on all engines, use a magnetic base dial indicator. Push the Camshaft to the rear of its travel in the block, install the dial indicator on the camshaft gear/sprocket retaining bolt, and zero it. Use a large screwdriver to pull the camshaft forward and release it, noting the reading on the dial indicator for the endplay measurement. If excessive, check the spacer installation; if correct and endplay remains too great, replace the thrust plate. For the 4.9L engine, check the timing gear backlash by installing a dial indicator on the cylinder block against the timing gear, zeroing the pointer, and moving the camshaft timing gear until all slack is taken up, then reading the dial indicator. If backlash is excessive, replace both the timing gear and the crankshaft gear. To check the timing gear runout, install a dial indicator on the engine block with the stem touching the timing gear face, hold the camshaft gear against the thrust plate, zero the indicator, and rotate the crankshaft to turn the camshaft while holding the gear against the plate. Observe the reading during one complete revolution; if runout exceeds specifications, check for foreign objects or burrs between the camshaft and gear flanges, and if none are found, replace the gears. A similar procedure applies to check the crankshaft gear runout, ensuring the crankshaft is against one end of the thrust bearing to avoid measuring endplay instead of actual runout.Answered by Ford Parts Specialist Clayton / May 06, 2025
