2 3 POSITION INDEXING CYLINDER WM38 PRODUCT DESCRIPTION DESCRIPTION The WM38 series indexing cylinder is a heavy duty pneumatic control device is frequently used in positioning applications. The unit consists of a pair of double-acting cylinders which share a common center barrier plate. In most applications, one piston rod is mounted in a fixed position while the other rod moves to a maximum of three positions. The WM38 cylinders are available with field-adjustable, factory preset, or fixed stroke configurations. OPERATION The WM38 cylinder requires an air connection to each of its four ports. As illustrated below, the cylinder is normally controlled by four three-way valves or by three such valves with a dual shuttle valve. Pressure is simultaneously applied to two cylinder ports and exhausted from the other two ports. In response to the pressure signal, the pistons move to one of the stroke positions. The WM38 produces an actuating force equal to the effective surface area of the piston multiplied by the pressure applied to the piston. APPLICATION The most common usage of the WM38 is in shifting systems of heavy duty automatic transmissions. The WM38 cylinders are also used for shifting auxiliary power take off units and operating clutch mechanisms on equipment such as drum winches. The WM38 cylinders may be purchased alone or in cylinder kits which contain mounting hardware. 3 POSITION INDEXING CYLINDER TYPICAL INSTALLATION EXTERNAL CONFIGURATION

6 POSITION INDEXING CYLINDER WM39 PRODUCT DESCRIPTION DESCRIPTION The WM39 heavy duty indexing cylinder serves as a pneumatic control device in positioning applications. Each unit is composed of two shorter double-acting cylinders that share a common center casting. The WM39 cylinders are available with field-adjustable, factory-preset or fixed stroke configurations. One piston rod is usually mounted in a fixed position while the other rod strokes to a maximum of four positions. If the stroke at one end is equal to twice that of the other end, the four stroke positions will be evenly spaced. OPERATION As illustrated in the installation schematic below, a multiple shuttle valve and four three-way valves are normally used to pressurize the WM39 cylinder. Pressure must be applied to one side of each piston to change the cylinder s stroke position. When two cylinder ports are pressurized, pressure is simultaneously exhausted from the two other ports, and the piston rods move to a new stroke position. The WM39 cylinder produces an actuating force that is equal to the piston s effective surface area multiplied by the pressure applied to the piston surface. APPLICATION The WM39 cylinder is commonly used in shifting systems of heavy duty automatic transmissions. These cylinders are also used to shift auxiliary power takeoff units. Some WM39 models are available with mounting hardware in cylinder kits. POSITION INDEXING CYLINDER TYPICAL INSTALLATION EXTERNAL CONFIGURATION

10 WM8 SERIES HEAVY DUTY CYLINDER SINGLE ACTING PRODUCT DESCRIPTION DESCRIPTION The WM8 single acting cylinder is a spring-returned pneumatic control device engineered for heavy duty vehicular or industrial service. Each WM8 model strokes to a fixed position (the stroke length options are listed in the ordering information block). On the stationary end of the cylinder, one of the following three end caps is used: () a die cast end cap with locknuts, rubber washers and a 3/8 mounting stud; a cast iron end cap that features an integral trunnion and bushings for a 5/6 inch pin. On all cylinder models, the piston rod is threaded for installing a clevis or a rod end. A clevis and additional mounting provisions are included on cylinder kit configurations. OPERATION The WM8 series cylinder requires only one air connection. A threeway control valve is normally used to deliver pressure to the cylinder s control port. When this port is pressurized, the piston strokes to its full stroke position. Because the cylinder is spring-loaded, the piston returns to its normal position when pressure is released. IMPORTANT: The return spring is designed to provide only the force required to retract the piston. If the actuated device requires any return force, an external spring should be added to the WM8 or double-acting cylinder should be used. APPLICATION The WM8 series cylinders should be used only in applications where work is performed as the piston is extended. Typical applications include holding, clamping or positioning operations. In such applications, the cylinder repositions itself after each ac- EXHAUST PUSH BUTTON CONTROL VALVE tuation. WM8 SERIES SINGLE ACTING CYLINDERS

16 DOUBLE ACTING CYLINDER WM63 PRODUCT DESCRIPTION DESCRIPTION The WM63 is a large double acting cylinder engineered for applications where linear operating force is required in both stroke directions. The stroke is fixed on each cylinder but the stroke length varies from model to model in the WM63 series (Refer to the ordering information block for available stroke length options.). All cylinder models have an integral trunnion for mounting and a threaded piston rod for a clevis. The longer the stroke models do not include dust boots. OPERATION Each WM63 cylinder has two ports which require air connections. To effect piston movement, pressure must be applied to one side of the piston. When one cylinder port is pressurized, pressure is exhausted from the other port and the piston strokes by a fixed amount. APPLICATION The WM63 cylinder is commonly used to control mechanical devices on heavy duty industrial equipment. Since the WM63 cylinder produces more force than a.00 inch (5 mm) diameter cylinder, the WM63 is also used for direct-acting linkage applications such as the operation of two-position valves on dump trucks or the control of sequencing functions. The cylinder is normally pressurized by a single four-way control valve. Quick release valves are often used between the control valve assembly and the cylinder to improve the cylinder s response to the control signal.

20 3-POSITION FEATHERING CYLINDER WM75 PRODUCT DESCRIPTION DESCRIPTION The WM75 is a feathering cylinder used in systems that require infinite positioning in two directions from a given center position. The cylinder stroke in either the extension or retraction direction is limited to a fixed maximum. This stroke maximum varies according to the WM75 series model. Models also differ in the type of end cp used on the stationary end of the cylinder. The following end caps are available: () a die cast end cap with locknuts, washers, and a 3/8- UNF mounting stud; or () a cast iron end cap that incorporates a trunnion for a / inch pin. All WM75 models have a threaded piston rod for installing a clevis or a rod end. OPERATION To obtain variable positioning of the WM75, a compensating dual control valve is normally used to modulate pressure delivery to the ports. When pressure is applied to one cylinder port, it is simultaneously exhausted from the other. Fro the center position, the piston can be positioned at any point between the full extension and retraction positions, depending on which port is pressurized, and to what degree. When pressure is released from both ports, a spring centers the piston in the normal position. APPLICATION WM75 cylinders are frequently used in air over hydraulic systems. Some common applications are remote control of hydraulic spool valves, hydrostatic transmission control (See WM796 catalog page.), and boom positioning in crane-hoist applications. 3-POSITION FEATHERING CYLINDER FUNCTIONAL DIAGRAM SUPPLY 3/8- UNF-A

23 3-POSITION FEATHERING CYLINDER WM95 PRODUCT DESCRIPTION DESCRIPTION Designed for heavy force applications, the WM95B is a double acting feathering cylinder that has a 3.5 in. (83mm) bore. From the normal center position, the cylinder piston can stroke to any point between the maximum extension and retraction positions. The cylinder varies its stroke position according to the regulated pressure signal that it receives. To anchor the stationary end of the WM95B, the customer must supply a / inch pin for the built-in trunnion and bushings. The customer may also install a clevis or a rod end on the threaded end of the piston rod. OPERATION To achieve infinite positioning of the cylinder, a compensating dual control valve is used to regulate pressure to the two cylinder ports. When pressure is applied to one port, it is simultaneously exhausted from the other. From the center position, the cylinder can stroke to any point between the full extension and retraction positions. The desired stroke is obtained by controlling the pressure signal to each port. When pressure is released from both ports, the cylinder is spring-returned to the center position. APPLICATION In air-over-hydraulic systems, the WM95B is often used for remote control operation of hydraulic spool valves. This cylinder is engineered specifically for heavy force systems such as large diameter hydraulic spool valves. A high-flow compensating dual control valve is normally used to modulate pressure to the cylinder.

25 3 POSITION MODULATING CYLINDER WM633B PRODUCT DESCRIPTION DESCRIPTION The WM633B is a spring-centered modulating cylinder with a.5 inch (3 mm) bore. The WM633B is engineered for systems that require infinite positioning in either of two stroke directions from a fixed center position. The stationary end of the cylinder has an integral bushed trunnion for mounting with a customer-supplied 5/6 inch pin. The piston rod is threaded for installing a clevis or rod end. OPERATION The WM633 modulating cylinder requires an air connection for each of its two ports. Pressure is normally supplied by a compensating dual control valve that can apply a variable pressure to either end of the cylinder. When pressure is applied to one port, the other port is in the exhaust mode. By regulating pressure to one or the other port, the piston can be positioned at any point between the maximum extension and retraction positions. When both ports are vented to the atmosphere the spring returns the piston to the center position. APPLICATION The WM633B is engineered primarily for the remote control operation of small hydraulic spool valves in air-over-hydraulic systems. Because of its compact size, this cylinder is ideal for applications where space is limited. 3 POSITION MODULATING CYLINDER

27 SINGLE WM635 SERIES ACTING CYLINDER WM INCH SINGLE ACTING CYLINDER DESCRIPTION The WM635 series single acting cylinder is a heavy duty, two-position pneumatic actuator device. Engineered for vehicular or industrial applications where space is limited, the WM635 is a.5 inch (3mm) diameter cylinder that is available with a variety of fixed stroke lengths. The stationary end of the cylinder incorporates a bushed trunnion for mounting, and the piston rod is threaded for installing a clevis or rod end. OPERATION The WM635 cylinder requires an air connection at one end. The cylinder port is normally pressurized by a three-way control valve or three-way valve and a three-way relay valve. Pressure must be applied to one side of the cylinder piston to effect piston movement. When pressure is applied to one port, the other port exhausts and the piston strokes a fixed amount. An internal spring returns the piston when application air is released. APPLICATION The WM635 cylinder is engineered for applications where working force is required in one direction only. Typical applications include remote actuation of multiple spool hydraulic valves and latching/unlatching functions.

The stationary end of the cylinder incorporates a bushed trunnion for mounting, and the piston rod is threaded for installing a clevis or rod end. OPERATION The WM637 cylinder requires an air connection at each end. The cylinder ports are normally pressurized by a four-way control valve or three-way valve and a three-way relay valve. Pressure must be applied to one side of the cylinder piston to effect piston movement. When pressure is applied to one port, the other port exhausts and the piston strokes a fixed amount. APPLICATION The WM637 cylinder is engineered for applications where working force is required in both directions of stroke. Typical applications include remote actuation of multiple spool hydraulic valves and latching/unlatching functions. The WM637 series cylinders are not designed for modulating or feathering applications. TYPICAL APPLICATION.5 INCH DOUBLE ACTING CYLINDER I.S.O. SYMBOL L 0-003
