Diesel engine parts for rebuild and overhaul in stock

Caterpillar, Komatsu and Isuzu Engine Parts for Heavy Equipment

Mahmut Usta Yedek Parca supplies engine components for excavators, wheel loaders, dozers and other construction, mining and industrial machinery. Engine parts are matched by engine model and original part number rather than by machine model, since the same machine series can be fitted with different engines depending on production year and market.

Caterpillar engine parts

We supply parts for Caterpillar engines including the C4.4, C6.6, C7, C9, C12, C13 and C15 series, as well as the 3116, 3126, 3306, 3406, 3406E and 3408. Available components cover cylinder liners, pistons, piston rings, bearings, crankshafts, camshafts, cylinder heads, valves, connecting rods, oil pumps and full gasket sets. Caterpillar engines are also used in diesel generator sets and marine power units, so parts are matched by engine serial number in those applications.

Komatsu engine parts

Parts for Komatsu engines including the SAA6D107E, SAA6D114E, S6D102, 4D95 and 6D125 series. These engines are fitted to PC200, PC300 and PC400 excavators, WA series wheel loaders, D65 and D85 dozers and Komatsu forklifts.

Liner and piston kits, crankshafts, camshafts, cylinder heads, valves, turbochargers and repair kits are supplied in original and equivalent quality.

Isuzu industrial engine parts

Isuzu builds many of the diesel engines used in construction machinery, and the 4LE2, 4HK1, 6BG1 and 6HK1 series are found in Hitachi, JCB, Case, Sumitomo and Kobelco excavators. These are industrial engines, not automotive units, and parts are not interchangeable with Isuzu truck applications. We supply cylinder heads, liners, piston kits, crankshafts, turbochargers, water pumps and gasket sets for Isuzu industrial engines, matched by engine model number stamped on the block.

Volvo construction equipment engine parts

Volvo engines used in construction equipment the D4D, D5D, D6E, D7E, D13 and TAD series are different from Volvo Penta marine and Volvo truck engines, and their parts are not interchangeable. We supply engine components for Volvo EC210, EC240, EC290 and EC360 excavators and L110, L120 and L150 wheel loaders. When ordering, please state the engine designation from the engine plate rather than the machine model, as several engine variants were fitted across the same excavator series.

JCB Dieselmax engine parts

For JCB 3CX and 4CX backhoe loaders we supply parts for Dieselmax 444 and 448 engines, including liners, pistons, crankshafts, camshafts, cylinder heads, valves, injectors and gasket sets. JCB machines can be identified through the serial number on the machine plate, and the engine number is stamped separately on the block. Sending both numbers is the fastest way to confirm fitment.

Cylinder heads and valve train

Complete cylinder heads, bare heads, head overhaul kits, intake and exhaust valves, valve springs, guides, seats, rocker arms and push rods for Caterpillar, Komatsu, Isuzu, Volvo, JCB, Hitachi, Case and New Holland engines.

Liners, pistons and rings

Cylinder liners, liner sleeves, liner kits, pistons, piston pins, piston ring sets, oversized pistons and pre-combustion chambers determine compression, fuel consumption and emission levels. Liner and piston kits are supplied as complete sets or as individual components. Please state the engine model and the repair size when requesting a quote, since the same series can use liners with different seating dimensions.

Crankshafts, camshafts and bearings

Crankshafts, camshafts, camshaft bushings, main and connecting rod bearings, connecting rods, engine gears and dampers. Crankshafts are available in standard and undersized dimensions for reground applications.

Turbochargers and airflow

Complete turbochargers, turbo cartridges, turbo repair kits, intake and exhaust manifolds, mufflers and charge air pipes for Caterpillar, Komatsu, Isuzu, Volvo, Hitachi, JCB, Case and New Holland machines.

Overhaul kits

Inframe overhaul kits contain liners, pistons, rings, bearings and a complete gasket set, allowing a rebuild without removing the engine from the machine. Upper and lower gasket sets, connecting rod repair kits and cylinder block repair components are supplied separately. Because every part in the kit is matched to the same repair size, an overhaul can be planned with a predictable outcome and shorter machine downtime.

Lubrication, drive and protection

Oil pumps, oil pickup screens, belt tensioners, drive belts, pulleys, heat shields and oil filler caps.

Part number lookup

Engine parts can be identified by engine model, by machine serial number or by original part number. We work with Caterpillar, Komatsu, Volvo, JCB, Hitachi, Isuzu, Hidromek, Case and New Holland equipment. The engine number is stamped on the cylinder block and is different from the machine serial number it is the engine number that determines fitment. Cross reference between OEM numbers and equivalents is provided free of charge.

Operating conditions

Engine components on heavy equipment work under high load, elevated temperatures, dust and continuous operation. Precise tolerances, correct heat treatment and consistent material quality are what keep rebuild intervals long and total operating cost down.

Application areas

Engine components are used in excavators, wheel loaders, track loaders, backhoe loaders, dozers, motor graders, articulated dump trucks, rigid haul trucks, hydraulic mining excavators, underground mining machines, forestry equipment, skid steer loaders and drilling rigs.
