Isuzu Trooper>> Engines>> Electric equipment and capital repairs of engines>> Capital repairs of engines>> Valves and springs>> Check of springs Check of springs


Check of pressure of a spring of the valve by means of testers

Check of length of a spring in a free state and its cross deformation

1 – deformation size

2 – spring

Establish a spring on a plain surface near a square and check height and a deviation from a vertical for what the spring should be turned concerning a square. If at turn of a spring it is found out that height changes more than on 1,5 mm, or the deviation from a vertical exceeds 1,5 mm, then replace a spring. It is necessary to measure also dispersion of pressure of a spring in a condition of the closed and open valve (height is in a condition of the closed valve by subtraction from height of the open valve of size of its rise). For springs of engines with a volume up to 3,0 l the dispersion (±) of 0,4 kgfs, and for engines with large volume – to (±) 2,0 kgfs is allowed.
