After the Screw Jacks, shafting, gearboxes, etc., are coupled together it should be possible to turn the main drive by hand. Ifthere are no signs of binding or misalignment, the Screw Jack system is then ready for normal operation.3.1.4 The Screw Jacks should have a greater raise than is needed in the actual installation. Should it benecessary to operate the Screw Jacks at the extreme limits of travel it should be done cautiously.3.1.5 It is important that the lifting screws should not be closed below the specified closed height dimension ofthe Screw Jacks, otherwise serious damage may result to the worm gear. Lifting screw end stops are to prevent over-travel or loss of screw. These are not load supporting and should be treated as anemergency device only and must not be allowed to come into contact with the worm gears during normal working cycles otherwise serious damage will result to worm gears and bearings.3.1.6 The maximum worm shaft speed for these Screw Jacks should not exceed 500 R.P.M. for heavy loads.Refer to Power Jacks Limited for higher worm shaft speeds for lighter loads. Absolute maximum is3000rpm provided Power Jacks have advised acceptable.3.1.7 The lifting screws should not be permitted to accumulate dust and grit on the threads. If possible, liftingscrews should be returned to the closed height position when not in use.3.1.8 A periodic check of backlash between lifting screw and worm gear is recommended to check wearon internal threads of worm gear. Backlash in excess of 50% thread thickness indicates that areplacement will be necessary to replace the worm gear and nut assembly.3.1.9 The Screw Jacks are shipped with the gearbox housing oil filled (unless otherwise required) to thecorrect level and with the lifting screw packed with grease. This should be sufficient for normal operation.For normal operation the oil level should be checked to read the correct level and the lifting screwlubricated with grease once a month. For lubrication use one of the recommended lubricants (referTables1 & 2)3.1.10 For severe service conditions the Screw Jack should be lubricated with a molybdenium disulphide typeof grease daily or weekly depending on the conditions. If duty is heavy, an automatic lubrication system is strongly recommended. If ambient temperature exceeds 90°C (194°F) consult Power Jacks.4 Recommended LubricantsTABLE 1 – GEARBOX OIL TABLE 2 – LIFTING SCREW GREASEManufacturer Lubricant Manufacturer LubricantBP Energol GR-XP150 Shell Gadus S2V220AC2(Alvania WR2) Shell Omala Oil 150 PowerBP Energrease LC2PetroleumCastrol Alpha SP150 Castrol Spheerol EPL2Mobil Gear Oil 629 Mobil Mobilux EP2S-Screw Jacks5 General Assembly & Parts List5.1 General Arrangement – Part ATranslating ScrewRotating Screw121371921382213138624 24261252322 32 13862517171668 166 8 164016411611631141514142728 302931239S-Series – Screw Jacks5.2 General Arrangement – Part B5.3 Parts ListItem No DescriptionQty Item No DescriptionQty 1 Shell1 22Worm Gear (6:1 Ratio-Anti-backlash) Double Start 1 2 Shell Cap1 Worm Gear (8:1 Ratio-Anti-backlash) Double Start 1 Shell Cap Anti-backlash 1 Worm Gear (24:1 Ratio-Anti-backlash) Double Start 1 3 Guide Bushing1 23 Anti-backlash Nut1 4Worm Shaft (6:1 Ratio) 1 Anti-backlash Nut (Double Start) 1 Worm Shaft (8:1 Ratio) 1 24 Dowels4 Worm Shaft (24:1 Ratio) 1 25Worm Gear (6:1 Ratio - Rotating) 1 5Worm Gear (6:1 Ratio) 1 Worm Gear (8:1 Ratio – Rotating) 1 Worm Gear (8:1 Ratio) 1 Worm Gear (24:1 Ratio – Rotating)1 Worm Gear (24:1 Ratio)1 Worm Gear (6:1 Ratio- Rotating) Double Start 1 Worm Gear (6:1 Ratio) Double Start 1 Worm Gear (8:1 Ratio- Rotating) Double Start 1 Worm Gear (8:1 Ratio) Double Start 1 Worm Gear (24:1 Ratio- Rotating) Double Start 1 Worm Gear (24:1 Ratio) 1 26 ‘O’ Ring Anti-backlash Nut) 1 6 Load Bearing2 27 Key Adaptor1 7 Worm Shaft Bearing2 Key Adaptor (Anti-backlash) * 1 8 Seal2 28 Key (Lifting Screw) 1 9 Seal (Worm Shaft) 2 29 Cap Screw 1 10 Circlip2 30 Lock Washer1 11 Key (Worm Shaft)2 31 Secondary Guide Bushing1 12 Lifting Screw1 32 Name Plate (includes fixing screws) 1 Lifting Screw (Keyed)1 33Bellows Boot Kit 1 Lifting Screw (Double Start) 1 includes Bellows Boot 1 Lifting Screw (Rotating) 1 End Plate 1 13 O Ring (Shell Cap) 1 End Plate Gasket 2 14 Bottom Pipe1 34 Hex Headbolt 4 15 Bottom Pipe Cap 1 35 Washer4 16 Plug3 36 Locking Plug1 17 Breather Plug1 37 Lifting Nut – Single Start 1 18 Set Screw (M8 x 20mm) 1 Lifting Nut – Double Start 1 19 Clevis End 1 38 Drive Key (Lifting Screw) 1 20 Top Plate1 39 Lock Nut (Lifting Screw1 21 Set Screw (M8 x 12mm4 40 Grubscrew (Lifting Screw Locknut) 1 22Worm Gear (6:1 Ratio – Anti-backlash) 1 41 Bottom Cap 1 Worm Gear (8:1 Ratio – Anti-backlash) 1 Worm Gear (24:1 Ratio – Anti-backlash)1* For anti-backlash keyed inverted screw there is no internal thread on key adaptor.3334 353534 329107183618910114111291036S-Series – Screw Jacks6 Disassembly / Assembly Instructions (D.A.I.)6.1 Translating Screw D.A.I6.1.1 Main Unit6.1.1.1 Ensure that shell cap grub screw and plug (18) are slackened back clear of the thread grip (36) inshell (1) before unscrewing the shell cap (It may be necessary to tap shell cap loose). 6.1.1.2 On some models it will be necessary to remove the worm shaft (4) before the worm gear assemblycan be pulled clear of the shell. 6.1.1.3 Check all parts for damage or excessive wear and replace where necessary paying specialattention to “O” rings (13) & oil seals (8 & 9). 6.1.1.4 After re-assembly of the worm shaft assembly, strike each end of worm sharply with a wooden orfibre mallet to seat bearings properly. (Bearings must be assembled with the shield facing outwards). 6.1.1.5 Press oil seals (9) into worm recesses in shell housing (1) with the sealing members pointinginwards. 6.1.1.6 When re-assembling the worm gear and load bearings ensure that the bearings are fitted so thatthe plate with the smallest bore size fits over the worm gear spigot. 6.1.1.7 The shell cap should be fitted after the worm shaft assembly has been securely clamped and withthe worm gear assembly in position. Tighten the shell cap until a slight drag is felt on rotating the worm shaft by hand. 6.1.1.8 For anti-backlash Screw Jacks the shell cap must be screwed up with the lifting screw insertedand only as tight as to allow the required backlash and lifting screw and worm gear. For normal screw jack operation the recommended backlash is 0.05mm (0.002”). 6.1.1.9 Tighten shell cap grub screw (18). It may be necessary to fit a new thread grip if it has becomeworn due to numerous adjustments. 6.1.1.10 For keyed Screw Jacks it is recommended that the lifting screw be threaded into the worm gear asfar as required before fitting the key (28). 6.1.1.11 It is important that the detachable ends are securely fixed to the lifting screws and the followingprocedure should be adhered to.6.1.2 Instructions for fitting detachable ends on lifting screws.6.1.2.1 Thread the detachable end on to the lifting screw and tighten up as hard as possible withoutdamaging the components. 6.1.2.2 Select a twist drill, which is a free fit in the tapped holes of thedetachable end. Using these holes as a drill guide, drill dimple only into the lifting screw. Clean out swarf and remove detachable end. Select another drill which matches the set screw diameter and, using the drill dimples as a guide, drill into the lifting screw a full diameter depth of 1mm below the root diameter of the threads. Refit detachable end. 6.1.2.3 Fit the knurled point set screws (supplied with detachable ends) firmly inplace ensuring that point of set screws make contact with bottom of drill dimples. Secure the set screws with Loctite.6.1.2.4 If Screw Jacks with keyed lifting screws are involved, and it is required to line up the clevis flats ortop plate holes, etc. in a fixed relationship to the worm shaft centreline, it will be necessary to face the underside of the detachable end to obtain the required relationship. This operation should be done carefully as only a few hundredths of a mm (thousands of an inch) removed from the attachment is equivalent to a fair amount of rotational movement.1mm deep drill holesS-Series – Screw Jacks6.2 Rotating Screw D.A.I.6.2.1 Main Unit6.2.1.1 Ensure that shell cap grub screw and plug (18) are slackened back clear of the thread grip (36) inshell (1) before unscrewing the shell cap (It may be necessary to tap shell cap loose).6.2.1.2 On some models it will be necessary to remove the worm shaft (4) before the worm gear assemblycan be pulled clear of the shell.6.2.1.3 Check all parts for damage or excessive wear and replace where necessary paying specialattention to “O” rings (13) & oil seals (8 & 9).6.2.1.4 After re-assembly of the worm shaft assembly, strike each end of worm sharply with a wooden orfibre mallet to seat bearings properly.
