JF018E CVT Chain 712229010

The JF018E CVT Chain 712229010 is an internal drive component used in selected JF018E / RE0F10F continuously variable transmissions. The chain transfers torque between the variable pulley assemblies while allowing the transmission ratio to change continuously during vehicle operation. This product is intended for professional CVT workshops, transmission rebuilders, distributors and wholesalers that service Nissan and related Jatco continuously variable transmissions.

The JF018E is commonly identified as RE0F10F in Nissan applications. It belongs to the Jatco CVT family and uses a chain-based continuously variable drive system rather than a conventional stepped automatic gearset. Because internal chain dimensions and pulley designs can vary between CVT families, the transmission model and original chain reference should be confirmed before ordering.

JF018E CVT Chain Function

The JF018E CVT Chain works between the primary and secondary pulley assemblies. During operation, hydraulic pressure changes the effective pulley diameters while the chain transfers engine torque from one pulley to the other.

Accurate chain geometry is important because the chain operates under high load and must maintain proper contact with the pulley surfaces. Excessive wear, damaged links or abnormal elongation can affect torque transfer and transmission performance.

Possible symptoms related to chain or pulley wear may include slipping, abnormal mechanical noise, poor acceleration, ratio-control problems or metal debris inside the transmission. These symptoms do not automatically confirm chain failure. Hydraulic-pressure problems, worn pulleys, bearing damage, valve-body faults or incorrect CVT fluid can create similar symptoms.

Professional diagnosis is recommended before replacement.

LuK 712229010 Product Reference

The reference 712229010 is used for this LuK JF018E chain product. Because public OEM documentation is limited, this number should be treated as a LuK or supplier product reference rather than a Nissan OE number unless the original packaging provides manufacturer confirmation.

For your website, the safest wording is:

LuK Reference: 712229010

rather than:

Nissan OE: 712229010

This helps keep the product information accurate while still allowing customers to search by the number they know.

For accurate matching, customers can provide the original chain reference, transmission code, chain photos, pulley photos, vehicle information and required quantity.

JF018E and RE0F10F Application

JF018E and RE0F10F are commonly used to identify the same Jatco CVT transmission family. These transmissions appear in selected Nissan and Infiniti applications depending on market, production year and vehicle configuration.

Because the same vehicle model can use different CVT generations, customers should not select a replacement chain only by vehicle name. The transmission model and original chain specification are more reliable identification methods.

If the transmission has already been disassembled, comparing chain width, link design and pulley configuration can help confirm the correct version.

Chain and Pulley Inspection

Before installing a new JF018E CVT Chain, technicians should inspect both pulley assemblies carefully. A worn pulley surface can damage a replacement chain and may cause repeated transmission failure.

Inspection should include:

• Primary pulley surface condition
• Secondary pulley surface condition
• Bearings and bushings
• Hydraulic pressure system
• Oil pump condition
• Valve body operation
• CVT fluid condition

Scoring, grooves or abnormal polishing on the pulley surfaces may indicate that the pulley set also requires repair or replacement.

Metal contamination inside the transmission should be cleaned thoroughly before reassembly. CVT internal components operate with tight tolerances, so cleanliness is especially important during rebuilding.

Professional CVT Rebuilding

The chain should be installed using professional transmission procedures and the correct CVT fluid. After assembly, technicians should verify hydraulic pressure, pulley operation and transmission control functions.

A replacement chain cannot correct problems caused by insufficient hydraulic pressure, damaged pulleys or internal bearing wear. Complete system inspection helps reduce repeated failures after rebuilding.
