Use only a mild, non-corrosive cleaning agent. Remove any sludge, deposits, or other foreignsubstances from the surface of the : Do not use high-pressure wash down or steam-lance type cleaningsystemsLoctiteUse precautions contained with Loctite or any other adhesive used in procedureBall nutThe ball nut will be shipped from the factory pre-lubricated, however in order toassure proper operation of the cylinder additional lubrication is necessary.

3 Therecommended lubricating frequency is 5 to 6 times over the estimated life of theunit. The recommended lubrication is the Thomson Linear Lube. The lubricationfitting and access hole are provided in the 12 o clock position as standard unlessspecified differently in the part number is the procedure to be followed when re-lubricating the ball nut:Remove the plug (67) from the cylinder body (29). Stroke the cylinder until thelubrication fitting (64) is directly below the hole in the cylinder body. Wipe thefitting with a clean rag. Apply the lubrication until it begins to protrude out fromunder the ball nut bearingsThe taper roller thrust bearings in the rear end cap (7) are pre-lubricated at thefactory upon assembly.

4 Additional lubrication of these bearings is alsorecommended with a lubrication fitting (64) being provided in the cylinder endcap. The recommended lubrication is the Molygrease. This lubrication should bedone 3 to 4 times over the actuator life. The lubrication fitting for the thrustbearings is provided standard in the 3 o clock Exploded viewsAll parts in the following exploded views can be obtained through your Parker AutomationDistributor or through the Automation actuator 1 Basic actuator AssemblyDrawing 2 Inline AssemblyDrawing 3 Parallel AssemblyDrawing 4 Brake AssemblyIV.

8 Determine type of motor (inline or parallel).2. Referring to the appropriate illustration and specification table, assemble coupler or pulley tomotor. Make sure to measure the A dimension from the mounting face of the motor. Do notmeasure off of the pilot. Assemble and tighten set screw with Loctite Make sure to torque motor mounting hardware as necessary (if applicable).MotorParallel pulley"A" (mm)Inline coupler"A" (mm)APEX 640 Belt Tensioning Procedure1. Remove the rubber plug (76) in the back of the parallel housing plate (50) and back the M8 SHSS (75) off theflat of the bearing shaft (73).2.

9 Then remove the four socket head cap screws (52), the parallel bearing plate (50), and the gasket (51) out of theparallel Loosen the four flanged hex head cap screws (55). Loosen just enough to allow motor to move belt (47) tension. The correct deflection for the belt with finger pressure is mm. With belt tension toola. Attach belt tension tool assembly (shown below) to mounting plate (53). Support the motor in therear and then turn adjustment screw as required to properly tension the timing belt. Then tightenthe flanged hex head cap screws (55). for proper belt tension. Without belt tension toola.

10 Mount or hold the actuator Then lift up on the motor evenly until the belt has the proper tension. Tighten down the flangedhex head cap screws (55).c. Check for proper belt inspect for proper seating of belt teeth in pulley the four flanged hex head cap screws (55). (Refer to the torque values chart located earlier in thissection.)7. Place the gasket (51) and parallel bearing plate (50) onto the parallel housing (44) with the bearing shaft slidinginto the plate. Orient the bearing shaft and tighten the set screw onto the flat of the bearing up on the parallel bearing plate (50) and keep pressure on this plate as you torque the four button head capscrews (52).
