Checking the tightness of the cylinder head on the device A.60334
1, 2, 4 – plugs; 3 – fixture plate; 5 – flange with water supply nipple
1. For hydraulic testing of cylinder head cooling jacket tightness:
- install the parts included in the A.60334 fixture kit on the head;
- use a pump to pump water into the head under a pressure of 0.5 MPa (5 kgf/cm²).
2. There should be no water leakage from the head within 2 minutes. If cracks are found, the cylinder head must be replaced.
3. You can check the tightness of the cylinder head with compressed air, for which:
- install the parts included in the A.60334 tool kit on the cylinder head;
- place the cylinder head in a bath of water heated to 60–80°C and allow the cylinder head to warm up for 5 minutes;
- supply compressed air at a pressure of 0.15–0.2 MPa (1.5–2 kgf/cm²) into the cylinder head.
4. There should be no air leakage from the head within 1–1.5 minutes.
