Kit Contents

Everything you need for the core rebuild arrives together:

• Complete gasket set for the rebuild
• Cylinder liners, semi-finished (one set)
• Pistons, standard size (one set)
• Piston pins (one set)
• Snap rings (one set)
• Rod bushings (one set)
• Piston ring sets, standard size
• Main bearings (one set)
• Connecting rod bearings (one set)
• Thrust washers (one set)
• Intake and exhaust valves (one set)
• Valve guides (one set)
• Intake and exhaust valve seats (one set)

The cylinder liners are semi-finished, so your machine shop finishes them to suit your block. Pistons, rings, pins and snap rings are standard size. The block, crankshaft and cylinder head are not part of the kit.

Key Features

• One matched set. Every wear part is listed for the 4JE1, so you are not sourcing a rebuild from five different suppliers.
• Bottom end renewed together. New pistons, piston rings, pins, snap rings and rod bushings go in with fresh main bearings, rod bearings and thrust washers, which restores compression and oil pressure in one job.
• Top end included. Intake and exhaust valves, valve guides and valve seats let you recondition the cylinder head during the same teardown.
• Bearing sizes to suit your crank. Main and connecting rod bearings come in Standard, +0.25 mm and +0.5 mm, so the kit can match a crankshaft that was ground in an earlier rebuild.

Compatibility

This Isuzu 4JE1 rebuild kit fits the Isuzu 4JE1 engine. The applications listed are the Isuzu NFR truck and the Iseki TA357 and TA345 tractors. Match the engine code on your nameplate before you order.

Why Choose This Isuzu 4JE1 Rebuild Kit

Rebuilding is the practical route when the rest of the machine is still sound. Here is why buyers choose this Isuzu 4JE1 rebuild kit:

• Less downtime. One order covers the pistons, liners, bearings, valves and gaskets, so the teardown does not stall waiting for parts.
• Lower cost than replacement. Renewing the wear parts keeps a truck or tractor you already own working, instead of paying for a replacement engine or a new machine.
• The right sizes. You choose main and rod bearing sizes at checkout, so the kit matches your crankshaft.
• Fitment help before you buy. Send us your engine serial number or a nameplate photo and we will help you confirm the match. Learn more about Isuzu engines at Isuzu Diesel Engines.

FAQs

Which machines does the Isuzu 4JE1 rebuild kit fit?

The listed applications are the Isuzu NFR truck and the Iseki TA357 and TA345 tractors, all running the Isuzu 4JE1 engine. Check your nameplate to confirm the engine code.

How do I choose my bearing size?

Measure the crankshaft journals. If the crank has not been ground, Standard bearings are normally correct. A crank ground in an earlier rebuild needs the matching +0.25 mm or +0.5 mm size.

What is not included in the kit?

The engine block, crankshaft and cylinder head are not included. The kit contains the gaskets, liners, pistons, rings, pins, bushings, bearings, thrust washers, valves, guides and seats listed above.

Are the cylinder liners ready to install?

No. The liners are semi-finished and need final machining to suit your block.
