  • 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 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 PM50 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. 23121. REMOVAL OF HYDRAULIC MOTOR ASSEMBLY: If disassembly of the hydraulic motor is not necessary, proceed as follows: 1) Remove 12 hex capscrews item 821, together with lockwashers item 823, from motor adaptor item 800.

DISASSEMBLY OF BRAKE ASSEMBLY WITH BRAKE EFFECTIVE IN BOTH DIRECTIONS: Refer to PARTS REFERENCE on page 26 and BRAKE GROUP drawing G1064 on page 27. 1) Remove connecting shaft item 600. 2) Remove brake hub item 720, with ball bearing item 407.
  • Page 19 SERVICE INSTRUCTIONS CONTINUED DISASSEMBLY OF FINAL DRIVE AND OUTPUT SHAFT ASSEMBLY: If final drive or output shaft assembly requires service or repair, disassemble as follows: 1) Remove final sungear item 340, from center of three final planet gears item 320. 2) Pull out final planet hub assembly and inspect for wear or damage.
  • Page 20 SERVICE INSTRUCTIONS CONTINUED REASSEMBLY OF BRAKE HOUSING ASSEMBLY: Reassemble brake housing assembly by reversing disassembly procedure. 1) Install new, well-greased O-rings item 751 and 753, into glands of brake piston item 750. 2) Slide brake piston into brake housing with holes for brake springs facing out of brake housing (see BRAKE GROUP drawing).
  • Page 21 SERVICE INSTRUCTIONS CONTINUED REASSEMBLY OF BRAKE ASSEMBLY WITH BRAKE EFFECTIVE IN BOTH DIRECTIONS: Refer to PARTS REFERENCE on page 26 and BRAKE GROUP drawing G1064 on page 27. 1) Install internal gear item 430, into spring stopper item 770, and fasten with retaining ring item 772. 2) Install spring stopper item 770, onto brake housing item 700, using six capscrews item 771, and lockwashers item 773.
  • Page 22 SERVICE INSTRUCTIONS CONTINUED - Ensure that circulation supply flow is being supplied to and vented from brake housing. If an internal circulation model, fill with hydraulic oil through one of three filler / drain ports before running. - Run Planematic drive in hoisting direction, with no load, at reduced speed (approximately 30% of maximum hydraulic volume).

  • Page 23: 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.
