Step 01

Inspect the parts

Before assembly, inspectors check the barrel’s welds for cracks with magnetic particles and dye penetrant, and measure the bore, rod, gland and piston against the drawing.

Vapour rising from a bearing cooled in liquid nitrogen as technicians fit it into a cylinder eye.

Step 02

Assemble

Technicians fit the piston and gland onto the chromed rod. Bearings are cooled in liquid nitrogen so they shrink and slide into the cylinder eyes, and the bolts are tightened to a set torque.

Step 03

Pressure test

The assembled cylinder is run under hydraulic pressure on the test bench, to check for leaks and that it extends and retracts as it should.
