Illustration 18 g00902960
Tilt cylinderThe tilt cylinder is mounted inside the boom head. The cylinder head end is attached to the boom head and the rod end is attached to the linkage for the quick coupler.The cylinder is a double acting cylinder that is used to tilt the carriage forward and backward.Reference: See Systems Operation/Testing and Adjusting, "Main Hydraulic System" for more information.Lock for Load Control Valve (Tilt Cylinder)
Illustration 19 g00998270
Load control valve (tilt cylinder) (lock)The load control valve is installed into the head end of the tilt cylinder.The load control valve locks oil into the head end of the cylinder in order to hold the cylinder in position when the cylinder is stationary.The load control valve also prevents the tilt cylinder from collapsing if a hydraulic hose bursts.Reference: See Systems Operation/Testing and Adjusting, "Load Control Valves (Lock Valves)" for more information.Compensating Cylinder
Illustration 20 g00998259
Compensating cylinderThe cylinder is located at the bottom of the boom at the rear of the machine. The head end of the cylinder is attached to the outer section of the boom and the rod end is attached to the machine frame.The cylinder is a double acting cylinder. The compensating cylinder works with the tilt cylinder in order to maintain the selected angle of the carriage when the boom is raised and lowered. The compensating cylinder and the tilt cylinder utilize the same oil lines and the same control valve.Reference: See Systems Operation/Testing and Adjusting, "Main Hydraulic System" for more information.Load Control Valve (Compensating Cylinder Lock)
Illustration 21 g00999113
Load control valve (compensating cylinder lock)The load control valve is installed onto the bottom of the outer section of the boom.The load control valve prevents high pressure in the head end of the tilt cylinder from entering into the head end of the compensating cylinder.Frame Leveling Cylinder
Illustration 22 g00902970
Frame leveling cylinderThe frame leveling cylinder is located at the front of the machine on the right side. The head end of the cylinder is attached to the machine frame, and the rod end is attached to the front axle.The frame leveling cylinder allows the machine frame to be levelled in order to improve the stability of the machine during operation.Reference: See Systems Operation/Testing and Adjusting, "Frame Leveling System" for more information.Lock Valve (Frame Leveling Cylinder)
Illustration 23 g00902971
Lock valve (frame leveling cylinder)The lock valve is attached to the casing of the frame leveling cylinder. The valve controls the flow of oil into the cylinder and out of the cylinder. The valve also locks oil into both sides of the cylinder in order to hold the cylinder in position when the frame leveling system is in HOLD. Diverter Valve

Diverter Valve (auxiliary single)
Illustration 25 g00902965
Control Valve (dual auxiliary)The diverter valve is installed on the left side of the boom head.On TH220B standard machines, a single Diverter Valve (auxiliary single) is installed. A dual Control Valve (dual auxiliary) is installed as an option on the TH220B machines. The single Diverter Valve (auxiliary single) and the dual Control Valve (dual auxiliary) are available options on the TH330B and TH340B machines.The
