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 4JB1T and also covers the 4JB1, with replacement numbers such as 5-87310757-0, 8-94247867-1 and 8-94247869-1.
• Options to match your pistons. Pick square bottom or round bottom pistons and a 34 mm or 31 mm pin diameter, plus your main and rod bearing size.
• Healthy bottom end. Fresh bearings and tight cylinders protect the oil pressure a turbocharger relies on.
• Top end included. Valves, valve guides and valve seats are in the kit, so the head can be reconditioned in the same job.
• Fixes what you can hear and see. Blue smoke, rising oil use, hard starting and weak power under load usually trace back to worn rings, liners and bearings. Renewing them together addresses the cause.

Compatibility

This Isuzu 4JB1T rebuild kit fits the Isuzu 4JB1T and 4JB1 engines in the Bobcat 843, 853, 1213, 960, 2060 and 2070 skid steer loaders. Check the engine code on your nameplate before ordering.

While the engine is apart, check the turbocharger shaft play and clean or replace the oil feed line so debris from the old engine cannot damage a good turbo.

Why Choose This Isuzu 4JB1T Rebuild Kit

Buyers pick this Isuzu 4JB1T rebuild kit for the following reasons:

• One order. Pistons, liners, bearings, valves and gaskets arrive together.
• Built around a turbo engine. Fresh bearings matter when a turbocharger depends on steady oil pressure.
• Economical. A rebuild costs far less than replacing the engine or the loader.
• Parts that match each other. Buying pistons, liners, bearings and valves as one kit avoids mismatched sizes from separate suppliers.
• Help before you buy. Send your engine serial number and we will help you confirm fitment. Isuzu engine information is at Isuzu Diesel Engines.
