1:00 – 2:45
Optical inspection of the engine block: if there is damage or corrosion, reworking may be required. You must also inspect whether the engine block is warped and check that the liner flange seating surface is clean and level. Another very important check: inspect the O-ring grooves in the engine block.
2:45 – 3:40
The cylinder liner is pressed into the engine block with screws and sleeves. Then the liner protrusion is measured at four points (every 90 degrees) using a dial gauge and compared with the manufacturer's specifications.
Attention: if the amount of protrusion is insufficient, it must not be compensated using multiple tombak rings or washers. In such cases, you should use oversized liners that have a higher liner flange. Before removing the liner, mark its exact position in the engine block with a pen.
3:40 – 4:30
Insert the O-rings in the order depicted on the packaging. Attention: do not use liquid sealants under any circumstances. Now apply the installation paste onto the O-rings. Spread the rest evenly over the contact areas of the cylinder liners.
4:30 – 5:10
Insert the cylinder liner into the engine block with a smooth motion. Make sure that the markings on the engine block and cylinder liner align. As a final inspection, check the inside diameter using a bore gauge in the area of the O-rings.
