K21 K25 Timing Chain 13028-50k00 for Nissan Engine Repair Parts

Product Details

Product Overview

This heavy-duty timing chain, identified by OEM part number 13028-50k00, is specifically designed for precision fitment in Nissan K21 and K25 diesel engines. As a critical component of the engine timing system, this chain ensures synchronized rotation of the crankshaft and camshaft, preventing valve-piston interference and maintaining optimal engine performance.

Manufactured to OEM specifications, this timing chain serves as a direct replacement for worn or stretched units in industrial, agricultural, and construction equipment powered by these Nissan diesel platforms. While primarily developed for Nissan engine families, professional mechanics should verify compatibility with specific engine serial numbers before installation.

Key Features & Benefits

• OEM-Spec Construction: Manufactured to match original 13028-50k00 dimensions and tensile strength requirements for reliable timing accuracy
• Wear Resistance: Heat-treated alloy steel construction resists stretching and elongation under high-torque diesel operation
• Noise Reduction: Precision roller design minimizes operational noise compared to worn or aftermarket chains
• Direct Fitment: Drop-in replacement for K21 and K25 engines without modification requirements
• Corrosion Protection: Surface treatment resists rust during storage and operation in humid environments
• Extended Service Life: Designed to match or exceed original equipment replacement intervals

FAQ

Q: How do I verify this timing chain fits my specific Nissan K21/K25 engine?

A: While designed for K21 and K25 diesel engines, we recommend cross-referencing your engine’s serial number with our part number 13028-50k00. Measure your existing chain’s length (typically 114-120 links for these engines) and compare with the replacement. For engines with modified timing covers or aftermarket components, professional inspection is advised.

Q: What are the signs of timing chain wear that indicate replacement is needed?

A: Common symptoms include rattling noise from the timing cover area (especially on cold starts), rough idle, decreased engine power, and in severe cases, check engine light illumination. For diesel engines, stretched timing chains can cause injection timing drift, leading to hard starting and increased emissions. We recommend replacement every 100,000-150,000 km or when engine rebuild is performed.

Q: Should I replace other timing components when installing this chain?

A: Yes, best practice is to replace the timing chain tensioner, guides, and sprockets simultaneously to ensure even wear patterns and optimal service life. Worn guides can cause premature chain stretching, while a failing tensioner may allow chain slap. Consult your engine service manual for complete timing kit requirements for K21/K25 engines.
