FE6 Cylinder Liner Kit 11012-Z5604 12011-Z5702 Piston Ring Set with Pin for Nissan UD Trucks Engine

Product Details

Product Overview

This comprehensive engine overhaul kit is specifically designed for the Nissan UD FE6, FE6T, and FE6TA diesel engine platforms. The kit includes a dry cylinder liner, piston ring set, and piston pin, providing all the critical components needed for a complete engine rebuild or top-end overhaul. The kit is manufactured to match the exact specifications of OEM part numbers 11012-Z5604 and 12011-Z5702, ensuring a precise fit for Nissan UD Trucks and medium-duty buses commonly used in commercial fleets.

Each component in this kit is produced as a 100% brand new part, not a remanufactured or refurbished unit. The cylinder liner is made from durable boron cast iron, while the piston utilizes a lightweight aluminum alloy for optimal thermal efficiency. This combination is engineered to restore engine compression, reduce oil consumption, and extend the service life of your Nissan UD engine.

FAQ

Q: How do I confirm this kit fits my Nissan UD engine?
A: First, check your engine’s model number (look for FE6, FE6T, or FE6TA stamped on the engine block). Then, verify the part number of your existing cylinder liner or piston kit against our OEM cross-reference list (11012-Z5604 or 12011-Z5702). If both match, this kit is the correct replacement. If you are unsure, please contact us with your engine serial number and vehicle VIN for verification.

Q: Can I install this kit without removing the engine from the vehicle?
A: Yes, this is a cylinder liner and piston kit designed for an in-frame overhaul. However, proper installation requires specialized tools such as a liner puller, piston ring compressor, and torque wrench. The cylinder head must be removed, and the engine block deck must be clean and flat. We recommend having the work performed by a certified diesel mechanic to ensure proper ring gap orientation and liner protrusion.

Q: What maintenance is recommended after installing this overhaul kit?
A: After installation, follow a strict break-in procedure for the first 500 kilometers or 10 hours of operation. Avoid heavy loads and high RPMs during this period. Change the engine oil and oil filter immediately after break-in to remove any initial wear particles. Thereafter, adhere to the standard oil change intervals recommended for your Nissan UD engine (typically every 10,000-15,000 kilometers or 250 hours). Regularly check coolant levels and ensure the engine does not overheat, as thermal stress can reduce liner life.
