Starting at $3.95, AutoBuffy stocks 4 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.
The most important decision is matching the sprocket's tooth profile, chain pitch, and keyway dimensions exactly to your Ford Granada'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.
| Option | Best for | What you get |
|---|---|---|
| OE-Replacement Steel Sprocket | Daily drivers and vehicles within normal mileage range | Direct factory-spec fitment, correct tooth count and pitch, straightforward swap with no tuning required |
| Hardened/Case-Hardened Sprocket | High-mileage engines or vehicles in harsh operating conditions | Increased surface hardness for extended tooth life, better resistance to chain wear and heat-related deformation |
| Complete Timing Set (Sprocket + Chain + Tensioner) | Any vehicle where the timing chain has not been serviced recently | All wear components replaced together, eliminates chain stretch against a new sprocket, best long-term value |
| OEM (Dealer-Sourced) Sprocket | Owners who want exact factory part with OEM warranty coverage | Guaranteed specification match, ideal for vehicles still under powertrain warranty or with strict dealer service requirements |
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.
