1 Introduction Overview The Enerpac W-Series hydraulic torque wrench is designed for controlled tightening and loosening of fasteners in industrial bolting applications. Its low profile cassette, compact drive unit and integrated reaction foot make the W-Series ideal for use in locations where workspace is limited. Interchangeable W-Series cassettes are available in a large assortment of both metric and imperial sizes to suit specific customer requirements.
- - - - - - - - - of the tool when it is in operation. If the tool separates from the nut or bolt during operation it will detach in that direction. Tightening and loosening nuts and bolts involves little visible movement. The pressure and loads, however are extreme. Keep your hands away from the fastener being loosened or tightened. Make sure that the spanner used to keep the nut or bolt on the opposite end is secured. Always use Enerpac pumps and hoses.
3 Assembly and adjustments 3.1 Overview and features (fig. A or B) 1 Hexagon ratchet 2 Cassette 3A Swivel coupling or 3B TSP-Pro swivel coupling (optional) 4 Advance hose connection 5 Return hose connection 6 Hydraulic drive unit 7 Cassette release lever 8 Reaction foot Fig. A 3.2 To attach the positioning handle (fig. C) • Secure the positioning handle (9) with eye-bolt (10). Tighten hand tight. 3.3 Changing the cassette Make sure to depressurize and disconnect the tool from the hydraulic supply first.
• Push the release lever (7) back into the cassette (2). Make sure the ball detent clicks into place. Do not operate the tool if the cassette release lever is not fully closed. 3.4 Fig. D To connect the hoses (fig. F) Make sure all accessories meet the pressure requirements. Make sure the quick connect couplings are securely attached before operating the tool. The tool is fitted with male and female quick-connect couplings. Use Enerpac twin safety hoses only. Refer to the table below: Fig. E Fig.
4 Operation Fig. G 4.1 Prior to operation - Make sure the nut or bolt to be fastened is clean and free of dust. - Make sure the nut or bolt runs correctly on the thread. - Make sure that the threads and the bearing surface are liberally coated with the correct lubricant or antiseizure compound. - Make sure that the spanner used to keep the nut or bolt on the opposite end in place, is of the correct size and that there is an adequate abutment surface. Ensure that the spanner is secured.
Fig. I Fig. J 4.3.2 To loosen a nut or bolt (fig. I & J) • Apply penetrating oil to the threads. Allow the oil to soak. • Position the tool on the nut or bolt with the anti-clockwise (-) side facing upwards. • Position the reaction foot (17) against a suitable reaction point (18). The reaction point will counteract the force caused by operating the tool. • Start the pump. • Operate pump until nut (bolt) is loose. If the nut or bolt will be re-used avoid excess load when loosening.
5 Maintenance and troubleshooting Preventative maintenance can be carried out by the user. Full maintenance must be carried out by an approved and authorized technician appointed by Enerpac. Recommended service intervals are: a) 3 months – Heavy Duty use b) 6 months – Normal use c) 12 months – Infrequent use - Non destructive testing must be carried out if the tool has been used under severe conditions. 5.1 Preventative maintenance (fig. K & L) 5.1.
5.2 Full maintenance 5.2.1 The hydraulic drive unit • Remove the circlip from the swivel coupling. • Remove the couplings. • Remove the swivel-coupling block from the drive unit. • Remove the swivel post by removing the swivel post retaining screws. • Remove all ‘O’ rings from the swivel post. • Carefully hold the cylinder body to unscrew the cylinder gland. • Hold the two flat sides of the piston rod with a spanner. The rod is located at the spigot. • Remove the button head cap screw from the piston.
• As a check, refer to figure M and the tables below for the correct height of the drive unit retaining pin (Y). Pin Height - W22000 Series (fig. M, dimension “Y”) Metric Imperial 7,5 mm 0.296 inch Pin Height - W35000 Series (fig.
