COMPLETE ENGINE PISTON (PERKINS AK TURBO) SUITABLE FOR JCB - 02/201505

Technical Specification and Compatibility

A precision-manufactured, complete piston assembly, designed for major overhauls of Perkins AK (Turbo version) engines. This is the heart of the power unit, responsible for transferring energy from the combusted air-fuel mixture via the connecting rod to the crankshaft. Made from a high-grade aluminum alloy, it ensures optimal thermal expansion and durability. The piston crown (combustion bowl) and pin dimensions are precisely matched to the requirements of this turbocharged engine. The kit includes the piston, rings, pin, and clips.

GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

Essential for Engine Overhaul

  • › Cylinder liner (100 mm bore)
  • › Connecting rod bearings
  • › Full engine gasket set (top and bottom)

Application in machines

Brand Type / Series / Model
JCB Backhoe Loaders: 2CX, 3CX, 4CX
Telehandlers (Loadall)
Wheel Loaders
Agricultural Tractors: FASTRAC
JS Excavators
Skid Steer Loaders (ROBOT)

The list above is for reference. Fitment is dependent on the Perkins AK (Turbo, 100mm) engine model.

⚠️ Installation Warning

An engine overhaul is a complex process. Piston installation must be done in sterile conditions. Any contamination (dirt, metal shavings) entering the cylinder will immediately score the liner and destroy the engine. Always check piston ring end gaps and piston installation direction.

Part's Role in the Machine and Failure Diagnostics

The piston hermetically seals the cylinder (with piston rings) and transfers the immense force of combustion to the connecting rod. It is one of the most stressed components in the engine. Its failure necessitates a major overhaul.

  • › Loss of compression and hard starting.
  • › Increased oil consumption ("oil burning").
  • › Blue smoke from the exhaust.
  • › Loss of engine power and rough running.
  • › Metallic "knocking" from the engine (cracked piston or worn pin).

🔧 Expert's Guide: Key Installation Tips

  1. Replace as a set: Pistons should always be replaced as a complete set for all cylinders to ensure balanced weight, compression, and prevent future failures.
  2. Absolute cleanliness: Before installation, the cylinder and all components must be perfectly clean. Use assembly lube on rings and pin. The smallest piece of dirt acts like sandpaper.
  3. Installation direction: The piston has a mark (e.g., an arrow or "FRONT") indicating its correct orientation towards the front of the engine. Installing it backward will cause failure.
  4. Cylinder verification: Installing a new piston (even nominal 100mm) in a worn ("oval") cylinder is pointless. The cylinder must be verified, honed, or re-linered.

Frequently Asked Questions (FAQ)

1. What is the difference between this AK (Turbo) piston and the AA or AB pistons?

These pistons are very similar but absolutely not interchangeable. The main difference is the piston pin diameter and compression height. This AK piston has a 39.7 mm pin and 70.3 mm compression height. The AB piston (02/202245) has a 38.1 mm pin and 70 mm height. The AA piston (02/200904) has a 34.925 mm pin and 69.9 mm height. Installing the wrong piston will destroy the engine.

2. How do I know if I need a nominal or oversize piston?

This piston is a nominal size (100 mm). Before purchasing, a mechanic must measure the cylinder bore with a bore gauge. If the cylinder is worn but within tolerance, it can be honed for this piston. If the wear is too great, the cylinder must be "bored" (re-bored) and an oversize piston (e.g., +0.50 mm) must be used.

3. What is compression height (70.3 mm)?

This is one of the most critical dimensions of a piston. It defines the distance from the center axis of the piston pin hole to the crown (top surface) of the piston. Maintaining this dimension is crucial for achieving the correct compression ratio in the cylinder.
