Fifteen, oil pressure indicating valve wisdom oil and oil leakage

Oil pressure indicating valve oil is from the g5 mm hole of its joint, resulting in the oil pressure indicating valve logo can not be seen, oil reasons are:

1. The clearance between the indicating valve piston and the indicating valve hole on the cylinder head cover is too large, and the diameter of the indicating valve piston is 14 twenty-eight :83. Mm, indicating that the valve hole on the housing is 14*8-01° mm, it should be measured and the unqualified parts should be replaced.

2. The rubber ring of 4.9mm hole under the indicating valve joint is badly worn. If this kind of ring is not available, you can make your own punch with oil-resistant rubber plate.

3. The $2.5mm painting hole on the cylinder head cover housing causes the indicating valve to take off oil. At this time, the oil pressure indicating valve should be removed and the cylinder head cover housing should be cleaned.

4 indicator valve stem and indicator valve piston because of rivet is not strong and loose, oil pressure into the upper part of the indicator valve caused by oil, then should be reriveted indicating valve stem and piston.

5. The cylinder head cover shell on G3/8 "thread and its end face perpendicularity is out of whack, the joint is installed after uneven, oil leakage from the thread, then to repair file the cylinder head cover shell indicating valve hole end face.

16. Oil pipe leaks

1. The two planes at the oil pipe joint are not parallel. The joint surface should be filed and replaced with a new copper pad.

2. If there are sand holes, cracks or plane deformation of the two joints, the oil pipe should be repaired or replaced by welding.

3. Oil pipe bolt is not tightened or @ cover shell. On the 3l 8 x 1 screw hole slip buckle and oil leakage, then should tighten the pipe bolt, the cylinder head cover shell of the slip buckle sleeve treatment, or replace the new cylinder head cover shell.

4. Often disassemble the oil pipe, mace cushion produces coke or deformation causes oil leakage, then the cushion should be replaced.

5. The end face of the connection between the pipe bolt and the copper gasket causes oil leakage due to large roughness, and the pipe connection screw should be replaced.
