Cloyes S1139 Engine Timing Crankshaft Sprocket - Inner

Cloyes S1139 Timing Crankshaft Sprocket

The Cloyes S1139 timing crankshaft sprocket is a precision engine timing component built for exact tooth geometry, bore alignment, offset, and timing index. It works with the timing chain system to help maintain accurate crankshaft-to-camshaft synchronization in Ford and Lincoln applications.

Compatible With 2015-2021 Ford Edge, Inner; 2019-2021 Lincoln Nautilus, Inner; 2017-2020 Lincoln Continental, Inner; 2017-2020 Lincoln MKZ, Inner; 2017-2019 Ford Fusion, Inner; 2016-2018 Lincoln MKX, Inner; and 2015-2017 Ford F-150, Inner.

Product Details

Cloyes has focused on timing systems since 1921, and the S1139 reflects that experience in a crankshaft sprocket engineered for accurate timing control. The exact tooth profile, matched bore, and indexed offset help the sprocket work in step with the chain, tensioners, and guides. For Ford Edge, Ford Fusion, Ford F-150, Lincoln Nautilus, Lincoln Continental, Lincoln MKZ, and Lincoln MKX timing service, this sprocket supports the engine’s timing chain drive with the dimensional accuracy expected in a critical rotating component.

The Cloyes timing crankshaft sprocket line is built for timing system service where tooth engagement, chain tracking, and alignment matter. Part number S1139 is a direct reference for buyers searching for a Ford Edge timing crankshaft sprocket, Lincoln MKZ inner timing sprocket, or Ford F-150 inner crankshaft sprocket.

This part cross-references Cloyes (e.g., S1139) for the same application.

What It Helps Address

• Timing chain drive noise caused by worn sprocket teeth
• Incorrect chain indexing from damaged or mismatched timing components
• Crankshaft timing alignment issues during engine service
• Wear at the sprocket-to-chain contact surface
• Timing system inconsistency after related component replacement

Installation Notes and Tips

Verify engine application, inner position, tooth count, chain type, and timing mark alignment before installation. Cloyes recommends replacing the chain, tensioners, guides, and sprockets together during timing service to maintain timing system integrity. Confirm the keyway notch and bore dimensions match the original component before assembly.

Quality Assurance

Cloyes is a long-established timing systems brand, and the S1139 is precision-tooled for fit, reliability, and long-term performance. It is backed by Cloyes technical support and an industry-leading warranty.
