Ford Skyliner Engine Timing Crankshaft Sprockets
Ford Skyliner Engine timing crankshaft sprockets
Starting at $5.95, AutoBuffy stocks 2 engine timing crankshaft sprockets from Cloyes. This sprocket mounts on the crankshaft and drives the timing chain or belt, keeping valve timing precisely synchronized with piston movement. When it wears, jumps, or strips teeth, valve timing drifts — causing misfires, power loss, or catastrophic engine damage if ignored.
Signs your Ford Skyliner needs a new engine timing crankshaft sprocket
- Engine misfires or runs rough at idle and under load, often caused by valve timing slipping due to worn or rounded sprocket teeth
- Rattling or slapping noise from the front of the engine on cold starts, indicating the timing chain is skipping on a worn sprocket
- Check Engine light with stored codes for camshaft or crankshaft position correlation faults (e.g., timing over-advanced or retarded)
- Hard starting or extended cranking before the engine fires, especially after the vehicle has sat overnight
- Visible metal shavings or debris in the engine oil, which can result from a deteriorating sprocket shedding tooth material
- Engine stalls unexpectedly or surges under acceleration, consistent with intermittent timing chain skip across a worn sprocket
Which engine timing crankshaft sprocket should you buy for your Ford Skyliner?
The most important decision is matching the sprocket's tooth profile, chain pitch, and keyway dimensions exactly to your Ford Skyliner's engine, since even minor deviations will throw off valve timing. Beyond fitment, you'll choose between OE-quality steel sprockets and upgraded options with hardened tooth surfaces. Many mechanics also replace the full timing set — sprocket, chain, and tensioner — at the same time to avoid a repeat job.
OE-Replacement Steel Sprocket
Best for
Daily drivers and vehicles within normal mileage range
What you get
Direct factory-spec fitment, correct tooth count and pitch, straightforward swap with no tuning required
Hardened/Case-Hardened Sprocket
Best for
High-mileage engines or vehicles in harsh operating conditions
What you get
Increased surface hardness for extended tooth life, better resistance to chain wear and heat-related deformation
Complete Timing Set (Sprocket + Chain + Tensioner)
Best for
Any vehicle where the timing chain has not been serviced recently
What you get
All wear components replaced together, eliminates chain stretch against a new sprocket, best long-term value
OEM (Dealer-Sourced) Sprocket
Best for
Owners who want exact factory part with OEM warranty coverage
What you get
Guaranteed specification match, ideal for vehicles still under powertrain warranty or with strict dealer service requirements

Replacing the engine timing crankshaft sprocket on a Ford Skyliner
Advanced⏱ 3–6 hoursHarmonic balancer pullerCrankshaft holding tool or flywheel lockSocket set and breaker barTiming marks alignment tool or reference guide for your engineTorque wrench
Replacing the crankshaft sprocket requires draining coolant if the water pump shares the timing cover, removing the harmonic balancer with a dedicated puller, and carefully stripping the timing cover to expose the sprocket. Before removing the old sprocket, rotate the engine to top dead center and mark all timing reference points so the new sprocket is installed in the correct position. Reassemble the cover with a fresh gasket or RTV sealant as specified, torque all fasteners to manufacturer range, and verify timing alignment before starting the engine.
Frequently asked questions
How much does it cost to replace engine timing crankshaft sprockets on a Ford Skyliner?
The crankshaft sprocket itself starts at $5.95 at AutoBuffy. Total repair cost depends on whether you replace the full timing set and how labor-intensive front-engine access is on your Ford Skyliner. Professional installation can add several hundred dollars in labor, making this a significant but necessary repair when the part is worn.
Can I drive my Ford Skyliner with a worn timing crankshaft sprocket?
No — driving with a worn crankshaft sprocket is high-risk and not recommended. A sprocket with rounded or missing teeth allows the timing chain to skip, which immediately disrupts valve timing. On interference engines, this can cause the valves and pistons to collide, resulting in catastrophic and often irreparable internal engine damage.
How long does a timing crankshaft sprocket last on a Ford Skyliner?
Most crankshaft sprockets are designed to last the life of the engine under normal conditions, but wear accelerates with infrequent oil changes, oil starvation, or a stretched timing chain running against the sprocket for extended periods. Inspect the sprocket any time the timing cover is open or the chain is being replaced.
Should I replace just the crankshaft sprocket or the entire timing set on my Ford Skyliner?
Replace the full timing set — crankshaft sprocket, camshaft sprocket(s), chain, and tensioner — whenever the timing cover is removed. Installing a new sprocket against a worn chain (or vice versa) accelerates wear on the new component. The incremental cost of a complete set is small compared to repeating the labor a second time.
What causes a timing crankshaft sprocket to wear out prematurely on a Ford Skyliner?
The most common causes are neglected oil changes leading to oil sludge or low lubrication at the timing chain, a stretched chain that hammers against sprocket teeth over time, and prolonged operation after a timing chain rattle is first noticed. Using the correct oil viscosity and adhering to change intervals significantly extends sprocket life.
Is replacing a timing crankshaft sprocket a job I can do myself on a Ford Skyliner?
It is possible for experienced DIYers but should not be approached as a beginner project. The job requires removing the harmonic balancer, timing cover, and precisely re-timing the engine before reassembly. A mistake in timing alignment can cause immediate engine damage on startup, so mechanical confidence and proper tools are essential.
