Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Disassembly and Inspection Reference Exploded Assembly View Place Torqmotor in a vise 1. Place the Torqmotor in a soft jawed vice or similar support, with coupling shaft (14) pointed down and the vise jaws clamping firmly on the sides of the housing (21) mounting flange. WARNING IF THE TORQMOTOR IS NOT FIRMLY HELD IN THE VISE, IT COULD BE DISLODGED DURING THE SERVICE PROCEDURES, CAUSING INJURY. Figure 2 Scribe alignment 2.
HY13-1518-M1/USA Disassembly and Inspection Remove end cover & inspect bolts Low Speed High Torque, Hydraulic Motors TK Series 4. Remove end cover (2) and seal ring (5). Discard seal ring. SEE FIGURE 5. Figure 5 Wash & inspect end cover NOTE Remove & inspect commutator 6. Thoroughly wash end cover (2) in proper solvent and blow dry. Be sure the end cover flow areas, are free of contamination. Inspect end cover for cracks and the bolt head recesses for damage. Replace end cover as necessary.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Disassembly and Inspection Remove manifold NOTE Remove & inspect rotor set & wearplate NOTE 9. Remove manifold (6) and inspect for cracks surface scoring, brinelling or spalling. Replace manifold if any of these conditions exist. SEE FIGURE 9. A polished pattern on the ground surface from commutator or rotor rotation is normal. Remove and discard the seal ring (5).
HY13-1518-M1/USA Disassembly and Inspection Low Speed High Torque, Hydraulic Motors TK Series NOTE Series TK Torqmotor may have a rotor set with two stator halves (9B) with a seal ring (5) between them. Discard seal ring only if stator halves become disassembled during the service procedures. NOTE A polished pattern on the wear plate from rotor rotation is normal. Check rotor, vane clearance NOTE Remove & inspect drive link Remove thrust bearing 11.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Disassembly and Inspection Check coupling shaft for rust or corrosion 14. Check exposed portion of coupling shaft (14) to be sure you have removed all signs of rust and corrosion which might prevent its withdrawal through the seal and bearing. Crocus cloth or fine emery paper may be used. Remove any key (14A), nut (14B), washer, bolt, or lock washer still attached to the shaft. Remove & inspect coupling shaft 15.
HY13-1518-M1/USA Disassembly and Inspection Low Speed High Torque, Hydraulic Motors TK Series 18. Remove seal (18), backup washer (19), and backup ring (20) from TK Series Torqmotor housing by working them around unseated thrust washers (16) and thrust bearing (17) and out of the housing. Discard seal and washers. SEE FIGURE 16. Figure 16 Remove dirt & water seal 19. Remove housing (21) from vise, invert it and remove and discard seal (23). A blind hole bearing or seal puller is required.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Disassembly and Inspection Inspect housing bearings NOTE 21. If the housing (21) assembly has passed inspection to this point, inspect the housing bearings (22) and (15) and since they are captured in the housing cavity, the two thrust washers (16) and thrust bearing (17). The bearing rollers must be firmly retained in the bearing cages, but must rotate and orbit freely.
HY13-1518-M1/USA Torqmotor Assembly Low Speed High Torque, Hydraulic Motors TK Series • Replace all seals and seal rings with new ones each time you reassemble the Torqmotor unit. Lubricate all seals and seal rings with SAE 10W40 oil or clean grease before assembly. • NOTE: Complete seal kits are available. SEE FIGURE 22. The parts should be available through most OEM parts distributors or Parker approved Torqmotor distributors. (Contact your local dealer for availability).
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Torqmotor Assembly NOTE Bearing mandrel must be pressed against the lettered end of bearing shell. Take care that the housing bore is square with the press base and the bearing is not cocked when pressing a bearing into the housing.
HY13-1518-M1/USA Torqmotor Assembly Press in dirt & water seal Low Speed High Torque, Hydraulic Motors TK Series 3. Press a new dirt and water seal (23) into the housing (21) outer bearing counterbore. The dirt and water seal (23) must be pressed in with the lip facing out and until the seal is flush to .020 inches (.51 mm) below the end of housing. SEE FIGURE 28. Figure 28 Place housing assembly into vice 4.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Torqmotor Assembly Assemble backup washers & seal Housings (21) that did not require replacement of the bearing package will require that the two “captured” thrust washers (16) and thrust bearing (17) be unseated and vertical to the counterbore and the new backup ring (20), new backup washer (19), and new seal (18) be worked around the thrust bearing package and placed into their respective counterbores.
HY13-1518-M1/USA Torqmotor Assembly Low Speed High Torque, Hydraulic Motors TK Series CAUTION The outer bearing (22) is not lubricated by the system’s hydraulic fluid. Be sure it is thoroughly packed with the recommended grease, Parker Gear grease specification #045236, E/M Lubricant #K70M or Mobil Mobilith SHC ® 460 A packet of grease (P/N 406018) is included in each seal kit. NOTE The coupling shaft (14) will be approximately .10 inch (2.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Torqmotor Assembly Assemble seal ring Assemble wear plate and rotor set 12. Apply a small amount of clean grease to new seal rings (5) and assemble them into the seal ring grooves on the rotor set side of the wear plate (10) and on the manifold plate side of the rotor set stator (9B). 13.
HY13-1518-M1/USA Torqmotor Assembly Assemble end cover Low Speed High Torque, Hydraulic Motors TK Series 22. Assemble end cover over the commutator and in line with the alignment marks on the exterior of the motor. SEE FIGURE 40 and 41.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Torqmotor Assembly Assemble cover bolts 23. Assemble the 9 special bolts (1) and screw in finger tight. Remove and replace the two alignment studs with bolts after the other bolts are in place. Alternately and progressively tighten the bolts (SEE FIGURE 44),to pull the end cover and other components into place with a final torque of 44-55 ft. lbs. on each bolt. SEE FIGURE 42 & 43.
HY13-1518-M1/USA Final Checks Low Speed High Torque, Hydraulic Motors TK Series Final Checks • Pressurize the Torqmotor with 100 p.s.i. dry air or nitrogen and submerge in solvent to check for external leaks. • Check Torqmotor for rotation. Torque required to rotate coupling shaft should not be more than 50 ft. lbs. (68 N m) • On TK Series Torqmotor, pressure port with “A” cast under it on endcover (2) is for clockwise coupling shaft rotation as viewed from the output end of coupling shaft.
Low Speed High Torque, Hydraulic Motors TK Series HY13-1518-M1/USA Tips Tips for Maintaining the Torqmotor Hydraulic System • Adjust fluid level in reservoir as necessary. • Encourage all operators to report any malfunction or accident that may have damaged the hydraulic system or component. • Do not attempt to weld any broken Torqmotor component. Replace the component with original equipment only. • Do not cold straighten, hot straighten, or bend any Torqmotor part.
