Kit Contents

One kit delivers the core rebuild parts:

• 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 final 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. This listing targets engines stamped 4BD1T, and the same kit also covers the 4BD1 and 4BD1-T1.
• Piston height choice. Choose 98 mm or 104 mm so the pistons match your engine.
• Bearing sizes. Main and connecting rod bearings each come in Standard, +0.25 mm and +0.5 mm, so the kit can match a ground crankshaft.
• Complete wear set. Pistons, rings, pins, snap rings and rod bushings pair with main bearings, rod bearings and thrust washers, while valves, guides and seats cover the head.
• Fixes what you can hear and see. Smoke, rising oil use, hard starting and a loss of digging power usually trace back to worn rings, liners and bearings. Renewing them together addresses the cause.

Compatibility

This Isuzu 4BD1T rebuild kit fits the Isuzu 4BD1T, 4BD1 and 4BD1-T1 engines.

The Hitachi models listed are the EX90, EX100, EX100-2, EX100-3, EX100-4, EX120, EX120-2, EX120-3 and EX150. Confirm the engine code on your nameplate and compare your old piston with the 98 mm and 104 mm options before ordering.

Why Choose This Isuzu 4BD1T Rebuild Kit

Excavator owners choose this Isuzu 4BD1T Rebuild Kit because it keeps the repair simple:

• Back on site sooner. Pistons, liners, bearings, valves and gaskets arrive together, so the rebuild is not held up.
• Piston height up front. The 98 mm and 104 mm options reduce the risk of a wrong order.
• Cheaper than replacement. A rebuild keeps a machine you already own working for far less than a replacement engine.
• Help before you buy. Send your engine serial number and we will help you confirm fitment. Isuzu engine information is at Isuzu Diesel Engines.
