PISTON RING SET (100MM, 2.5x2.5x4, PERKINS AA) SUITABLE FOR JCB - 02/201938

Technical Specification and Compatibility

A key element for an engine overhaul – a high-quality piston ring set by NEXGEN. It is designed for one piston with a nominal cylinder bore (STD) of 100.00 mm. This set features specific ring dimensions of 2.5mm x 2.5mm x 4mm. It's primarily dedicated to the Perkins AA (1004-4) naturally aspirated engine, but also fits many other Perkins, CAT, and Massey Ferguson engines. The rings are responsible for hermetically sealing the combustion chamber, transferring heat from the piston to the cylinder, and controlling the oil film.

Part number: 02/201938
Type: Set for 1 piston
Size: STD (Standard)
Cylinder Bore: 100.00 mm
Ring Heights (Top/Mid/Oil): 2.5 mm / 2.5 mm / 4 mm

⚠️ Installation Warning

An engine overhaul requires absolute cleanliness. Installing rings must be done in sterile conditions. Any contamination (dirt, debris) entering the cylinder will immediately score the liner and seize the engine. Always ensure the cylinder is properly prepared (honed).

Part's Role in the Machine and Failure Diagnostics

Piston rings seal the combustion chamber, preventing exhaust gases from entering the crankcase and oil from entering the combustion chamber. They also transfer heat from the piston. Their wear is a natural process but leads to serious engine problems.

  • › Increased oil consumption ("oil burning").
  • › Blue smoke from the exhaust.
  • › Loss of compression and hard starting, especially when cold.
  • › Noticeable loss of engine power.

🔧 Expert's Guide: Key Installation Tips

  1. Cylinder Honing: When replacing rings, the cylinder wall must be honed. Without this, the new rings will not "seat" correctly, and the engine will burn oil.
  2. Check Ring End Gap: Before installation, insert each ring into the cylinder and use a feeler gauge to measure the gap. It must be within the engine's service specifications.
  3. Correct Order: Pay close attention to the order and orientation of the rings (compression, scraper, oil control). They often have a "TOP" mark indicating which side faces the piston crown.
  4. Stagger Gaps: When installing the piston, the ring gaps must be staggered (usually 120 degrees apart) so they are not aligned.

Frequently Asked Questions (FAQ)

1. What does the size 2.5x2.5x4 mean?

These are the heights (thicknesses) of the individual rings in the set, starting from the top of the piston. It means the first compression ring is 2.5 mm high, the second (scraper) ring is 2.5 mm, and the third (oil control) ring is 4 mm high.

2. Can I replace the rings on just one piston?

This is highly discouraged. Replacing rings on only one cylinder leads to uneven compression (the new cylinder will have much higher compression than the others). This causes unbalanced operation, puts stress on the crankshaft and bearings, and is considered bad practice. Such repairs should always be done for all cylinders.

3. Why must I hone the cylinder when replacing rings?

Old rings wear the cylinder wall in a specific way. The surface becomes too smooth ("glazed"), and new rings will not be able to "break in" or seal properly. Honing gives the cylinder wall a specific cross-hatch pattern that holds an oil film and allows the new rings to seat perfectly.
