There are two tilting cylinders oneach side of forklift.Tilting cylinder consist of piston, piston rod, cylinder body, cylinder bottom, guide sleeve andseal, piston and piston rod constructed by welding, there is a bearing and two h seals fitted onpiston outside end, there are shaft sleeve, Yx seal, retainer ring and dust-ring in guide sleeve, thisshaft sleeve support piston rod, seal ring, retainer ring and dust-ring to prevent leakage and dust,it is screwed onto cylinder body with O ring. See figure 2-59Skid valve pushing forward,high pressure oil comes in from bottom of cylinder,so as to pushpistion forward to make mast tilt forward.Pulling backward skid valve,high pressure oil enters fromfront of cylinder body,pushing piston backward to make mast tilt backward.1.earrings 2.dust ring 3.baffle ring 4.Yx seal ring 5.bearing6.O ring 7.guidebushing8.piston rod 9.cylinderbarrel10.Yx sealring11.bearing 12.Yx seal ring 13.pistonfigure2-59 tilting cylinder8.6 Hudraulic oil cylinderHydraulic oil tank is installed in rear right of framework.
