Car Engine Fiat Timing Chain Kit Suppliers

Fiat Timing Chain Kits Engineered for 1.3 Multijet and 1.4 T-Jet Platforms

As a Car Engine Fiat Timing Chain Kit Suppliers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Huzhou Nanxun Jingtong Auto Parts Manufacturing Co., Ltd. is a China-based manufacturer of complete Fiat timing chain kits, producing chains, tensioners, guides and sprockets for the 1.3 Multijet diesel and 1.4 T-Jet gasoline engine families. Our kits are built as direct replacement assemblies for workshops, distributors and engine rebuilders who require correct fitment and consistent material performance.

We operate two manufacturing facilities and an in-house international sales department, with a total facility footprint of 12,000 m2 across three branches. Our production follows GB/T14212-2003 and JB/T10348-200 standards, and every kit is assembled from components that meet our dimensional and hardness specifications.

Our Fiat Timing Chain Kit Range

Our custom car engine Fiat Timing Chain Kit company supplies complete kits for the most common Fiat engine codes. Each kit includes the timing chain, tensioner, guide rails and sprockets required for a full timing system replacement.

Additional kit references 1507, 1508 and 1509 cover later production variants. Each kit is assembled with the correct chain pitch, link count and guide profile for the target engine code.

Material and Hardness Differentiation

Fiat 1.3 Multijet and 1.4 T-Jet engines impose different loads on the timing drive. The diesel engine's higher compression ratio and torsional vibration require a chain with greater tensile strength and fatigue resistance, while the gasoline engine's higher maximum engine speed demands flexibility and wear resistance at elevated rpm.

• 1.3 Multijet diesel chain: 40Cr high-carbon chromium alloy steel, plate thickness 1.6 mm ±0.03, surface hardness 720–780 HV, pin diameter 4.5 mm, ultimate tensile load ≥22.0 kN.
• 1.4 T-Jet gasoline chain: 35Cr alloy steel, plate thickness 1.4 mm ±0.03, surface hardness 680–730 HV, pin diameter 4.0 mm, ultimate tensile load ≥16.5 kN.
• Guide rails: Diesel applications use glass-fiber-filled PA66 with 220°C heat deflection temperature; gasoline applications use PA66 rated to 180°C.
• Tensioner: Diesel requires 3.5–4.0 bar operating oil pressure; gasoline requires 2.8–3.2 bar.

These differences are not interchangeable. Cross-using a diesel chain on a gasoline engine or vice versa causes premature elongation, guide rail wear and potential valve timing faults. We maintain separate production cells and dedicated heat treatment furnaces for each variant to preserve material segregation.

Quality Control and Inspection

Every Fiat timing chain kit passes through in-process inspection and 100% final inspection before packing. Our testing laboratory is equipped with a spectrometer, metallographic microscope, tension tester, low temperature tester, X-ray tester, MPT, UT, CMM and video measurement machine.

• Chemical composition verification against GB/T14212-2003 and JB/T10348-200 standards.
• Surface and core hardness testing on every production batch.
• Tensile testing to confirm ultimate load capacity.
• Chain elongation measurement under dynamic fatigue cycles.
• Dimensional inspection of sprocket bore, keyway and tooth profile.

Our annual production capacity exceeds 5,000,000 single parts, supported by more than 100 employees including 5 engineers and 5 technicians. This capacity allows us to serve distributors and project buyers with consistent batch-to-batch quality.

Application Fit and Engine Code Verification

Correct fitment depends on matching the kit to the engine code, not just the vehicle model. The 1.3 Multijet diesel and 1.4 T-Jet gasoline engines share similar external dimensions but require different chain specifications. We label all packaging with engine compatibility codes and recommend verifying the engine code before ordering.

For workshops and distributors serving multiple Fiat models, we can supply mixed pallets with clear labeling for each engine variant. Our Audi Timing Chain Kit 1213 and Chevrolet 2.4 Car Engine Timing Chain Kit ranges follow the same engine-specific approach.

Customization and OEM Support

We support customized Fiat timing chain kits according to customer drawings or samples. Our R&D team can develop new kit configurations for engine variants not yet in our standard range, including specific chain lengths, guide profiles and tensioner settings.

• Custom chain pitch and link count for modified or older engine builds.
• Private label packaging and kit contents tailored to your market.
• Sample-based development for discontinued or low-volume Fiat applications.
• Technical drawings and material certificates supplied with production orders.

Information We Use to Configure Your Solution

To prepare an accurate quotation and kit configuration, we need the following project details. This information allows us to confirm the correct chain specification, kit contents and packaging requirements.

• Engine code and vehicle model year for each Fiat application.
• Required kit contents: chain only, chain and tensioner, or complete kit with guides and sprockets.
• Annual or per-order quantity and expected delivery schedule.
• Packaging requirements: neutral, private label or branded.
• Any specific inspection or certification documents required for your market.
• Destination port and preferred shipping terms (FOB, CIF, CNF).

We reply to inquiries within 12 hours on working days. For mass production orders, our standard payment terms are 30% deposit before production and 70% balance against copy of documents, with T/T as the most common method and L/C also acceptable.

Frequently Asked Questions

Can I visually identify whether a Fiat timing chain is for diesel or gasoline?

Yes. The diesel chain has thicker link plates (1.6 mm vs. 1.4 mm) and a darker, matte pin finish from deeper carburization. Gasoline chains have brighter, slightly polished pins. Guide rails also differ: diesel guides have a rougher glass-fiber texture for higher temperature resistance, while gasoline guides are smoother.

How does Jingtong ensure material differentiation between diesel and gasoline kits?

We use separate production cells and dedicated heat treatment furnaces for each variant. Diesel chains use 40Cr steel with carburization reaching 62–64 HRC, while gasoline chains use 35Cr steel with 56–60 HRC hardness. Each batch undergoes tensile testing, hardness verification and chain elongation measurement under dynamic fatigue cycles.

What are the first warning signs of an incorrectly mixed Fiat timing chain kit?

Early signs typically appear within 5,000–15,000 km and include metallic rattling during cold start lasting 4–6 seconds, persistent P0016 or P0017 correlation codes, and visible black sludge around the tensioner housing from accelerated bushing wear. If these symptoms appear, stop driving and have the timing system inspected immediately.

Do you supply Fiat timing chain kits for engines not listed in your standard range?

Yes. We develop custom kits according to customer drawings or samples. Provide the engine code, required components and quantity, and our R&D team will confirm feasibility and lead time for a tailored solution.

What is your production capacity for Fiat timing chain kits?

Our annual production capacity exceeds 5,000,000 single parts across all timing chain system products. This capacity supports both large distributor orders and smaller project-based requirements without compromising batch consistency.

Which markets do you currently export Fiat timing chain kits to?

Our products are exported to more than 20 countries, including the United States, Germany, Russia, Uruguay and Algeria. We ship from Ningbo and Shanghai ports, with air freight available from Ningbo and Shanghai airports for urgent orders.
