The connecting rods are made of steel by sintering and forging and have split bearing caps. The bearing cap split runs along the horizontal axis of the bearing through two opposite sides of the connecting rod. In addition to ease of manufacture, the split parts made using a special technology form a strong seamless connection during assembly. The cylinder position is marked on the adjacent sides of the connection to identify the corresponding connecting rods and bearing caps. Aluminum/tin split plain bearings are used as connecting rod bearings.
The pistons have an open skirt. Each piston has three rings - two compression rings and one oil scraper ring. Each piston is mounted on a piston pin installed in a connecting rod bushing made of aluminum/tin.
Assembly of connecting rods and pistons
| Item name | Spare part catalog number | Description |
| 1 | - | Row A(right) |
| 2 | - | Row B (left) |
| 3 | - | Piston |
The piston number is stamped on the piston head and must match the cylinder number. The piston must be installed in the specified cylinder with the correct side:
- Row "A" - piston number and thick connecting rod flange facing the front of the engine.
- Row "B" - piston number and thin flange of connecting rod facing the front of the engine.
