Kit Contents

The kit is supplied as one complete set:

• 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)

Liners are semi-finished and need machining. Pistons and rings are standard size. The turbocharger, injectors, block, crankshaft and cylinder head are not included, so inspect them while the engine is apart.

Key Features

• Made for the turbo engine. The kit lists the Isuzu 4HE1T and also covers the 4HE1, 4HE1-N and 4HE1-TC engines.
• Renews the parts that wear first. New liners, pistons and rings restore compression, and fresh bearings restore oil pressure, which a turbocharged engine depends on.
• Top end covered. Valves, valve guides and valve seats are included, in 8, 12 or 16 valve options to match your head.
• Bearing options. Main and rod bearings come in Standard, 0.25 mm (.010) oversize and 0.50 mm (.020) oversize.
• Fixes what you can hear and see. Blue smoke, rising oil use, hard starting and weak pulling power usually trace back to worn rings, liners and bearings. Renewing them together addresses the cause instead of chasing symptoms one part at a time.

Compatibility

This Isuzu 4HE1T rebuild kit fits the Isuzu 4HE1T, 4HE1, 4HE1-N and 4HE1-TC engines in the Isuzu ELF, NQR, NPR and NPR-HD (1998-2004) and the GMC 3500, 4500 and 5500 (1998-2004).

Why Choose This Isuzu 4HE1T Rebuild Kit

Buyers pick this Isuzu 4HE1T rebuild kit for the following reasons:

• Complete wear-part set. Pistons, liners, bearings, valves and gaskets arrive together, so the rebuild keeps moving.
• Built around a turbo engine. Fresh bearings and tight cylinders matter more when a turbocharger depends on healthy oil pressure.
• Economical. A rebuild keeps a truck you already own on the road for far less than a replacement.
• Support before you order. Send piston photos or your engine serial number and we will help you confirm fitment. Isuzu truck engine information is at Isuzu Commercial Vehicles.
