  • Page 12: Installation Instructions

    INSTALLATION INSTRUCTIONS DANGER FAILURE TO FOLLOW INSTALLATION INSTRUCTIONS WILL RESULT IN PROPERTY DAMAGE, SEVERE INJURY OR DEATH. To ensure satisfactory operation, the PULLMASTER Planematic drive must be properly installed. Observe the following installation instructions: 1) The Planematic drive mounting structure must be strong enough to withstand operating torques without excessive deflection.
  • Page 13 OPERATING INSTRUCTIONS DANGER FAILURE TO FOLLOW INSTALLATION INSTRUCTIONS WILL RESULT IN PROPERTY DAMAGE, SEVERE INJURY OR DEATH. Verify proper installation, acceptable system back pressure and adequate brake circulation flow before operating the Planematic drive. 1) The standard Planematic drive brake applies only in counterclockwise rotation as viewed from the motor end of the unit.

  • Page 14: Troubleshooting

    TROUBLE SHOOTING GENERAL: Typical Planematic drive operating problems are caused by a malfunctioning hydraulic system. Verify hydraulic pressure and flow at the drive motor are as specified before dismounting or disassembling Planematic. IMPORTANT: Ensure that the hydraulic system reservoir is full and that the system pump is running at full rpm before doing any system checks.
  • Page 15 TROUBLE SHOOTING CONTINUED PROBABLE CAUSE FAILURE Brake will not hold load. Hydraulic system back pressure not per SPECIFICATIONS. Refer to procedure described in TROUBLE SHOOTING - HYDRAULIC SYSTEM PRESSURE AND PLANEMATIC TORQUE to verify system back pressure at motor. Brake piston release oil being trapped by hydraulic system control valve.
  • Page 16 SERVICE INSTRUCTIONS GENERAL: Before attempting disassembly of the PULLMASTER Model PH50 Planematic drive, the following instructions for disassembly and reassembly should be read and understood. It is suggested that all expendable parts, such as O-rings and oil seals, are not reused on reassembly. It is therefore important to have a Planematic seal kit (Part No.
  • Page 17 SERVICE INSTRUCTIONS CONTINUED NOTE: Pocket seals, body seals, and ring seals in the hydraulic motor assembly are not part of the PULLMASTER Planematic drive seal kit. The seal kit for the hydraulic motor can be ordered from the factory under Part No.
  • Page 18 SERVICE INSTRUCTIONS CONTINUED 15) Remove 16 brake springs item 752. Examine springs for damage and measure overall length. Overall spring length should be 1.99 inch. Springs measuring less than 1.93 inch should be replaced. 16) Pull brake piston item 750, out of brake housing, using two tapped holes in brake piston and two 1/2 inch - 13 NC capscrews.
  • Page 19 SERVICE INSTRUCTIONS CONTINUED 2) Slide keyed washer item 149, and lockwasher item 161, onto output shaft against tapered roller bearing item 151. Screw locknut item 159, onto output shaft against lockwasher. Tighten locknut to a point where 5 to 15 pounds of pull is required to rotate output shaft item 150, freely.
  • Page 20 SERVICE INSTRUCTIONS CONTINUED 13) Starting and finishing with divider plate, alternately install 13 divider plates item 714, and 12 friction plates item 715. 14) Install two sprag clutches item 723, onto motor drive shaft item 730. Slide sprag clutch aligner, and support washer item 717, onto motor drive shaft and fasten with circlip item 727.
  • Page 21 SERVICE INSTRUCTIONS CONTINUED IMPORTANT: After performing any service or repair work, reinstall Planematic drive according to INSTALLATION INSTRUCTIONS. Before operating Planematic drive, ensure that circulation oil is being supplied to brake housing. If an internal circulation model, fill with hydraulic oil through the uppermost drain port before running. To ensure proper reassembly, run Planematic drive in both directions without load.

  • Page 22: Recommended Maintenance

    RECOMMENDED MAINTENANCE In order to maintain the PULLMASTER Planematic drive in peak operating condition at all times, it is recommended that the following preventive maintenance procedure is carried out every 12 months or 500 operating hours, whichever occurs first.
