If waste packing is to be used it may be installedthru access hole provided in the adapter. Waste packing,not furnished with the Screw Conveyor Drive, may be usedas a separate seal option or in combination with eitherthe lip or braided seals. .INSTALLATION1. Determine the running position of the Screw ConveyorDrive. Running positions are shown in fig. 2. Note thatthe reducer is supplied with 7 plugs; 5 around the sides ofthe reducer for horizontal installbtions and 1 on eachface for vertical installations. These plugs must be arrangedrelative to the running position as follows:Horizontal Installations - Install the magnetic drain plugin the hole closest to the bottom of the reducer. Throwaway the tape that covers the filler/ventilation plug inshipment and install plug in topmost hole. Of the 3remaining plugs on the sides of the reducer, the lowestone is the minimum oil level plug.Vertical Installations - Install the filler/ventilation plugin the hole provided in the top face of the reducer housing.Use the hole in the bottom face for the magneticdrain plug. Of the 5 remaining holes on the sides of thereducer, use a plug in the upper housing half for theminimum oil level plug.p(q]L P(JL @y-yL PfgLPosition “A” Position “B” Position “C” Position “D”HDRIZDNTALPi&PAPRICATIONSp’a;;”Position “E” Posi lion 3VERTICAL APFLICATIOh3L6 : Brcathcr; D: Drain; L: 011 Level Plug; P: PlugFig. 2 - Mounting Positions442-2DL__ -.

Note: If motor mount, -motor and sheaves are to beinstalled on reducer before mounting Screw ConveyorDrive to trough end, bypass step 2; perform steps 3 and4. and then return to step 2.2. On sizes C3, C4,’ and C5 remove the plastic plugthat protects the threaded hole in the reducer and installeyebolt supplied with reducer. Hoist the Screw ConveyorDrive into position. Slide shaft into screw and adapter overtrough end studs. Only one set of adapter holes will fitover trough end studs. If the mounted position of theScrew Conveyor Drive varies by 15” from any of the fourhorizontal mounting positions shown in fig. 2, an incorrectset of holes has been selected for coupling adapter toreducer. This can be corrected by removing adapterscrews and rotating reducer to its proper position. Reinstalland tighten adapter screws to torque specified intable 3 on page 5. Install lockwashers and tighten nuts ontrough end studs. Attach drive shaft to screw.6. Retighten bolts and pipe plugs after a few daysoperation. This prevents oil leakage.3. Remove the three bolts from reducer housing requiredfor mounting the SCD Motor Mount. Place the motor mountin position and install the three housing bolts suppliedwith the motor mount. Tighten bolts to torque specifiedin table 3 on page 5.4. Install motor, drive sheave and driven sheave so thatdriven sheave is as close to the reducer housing as practical.Install V-belt and tension with the four adjustingscrews provided on the SCD Motor Mount. Make requiredelectrical connections for motor.5. Because reducer is shipped without oil, it is necessaryto add the proper amount before operating the drive.Use a high grade petroleum base, rust and oxidation inhibited(R & 0) gear oil - see lubrication tables.Fig. 3 - Complete DriveNote: Belt guard removed for photographic purpose.LUBRICATIONUnder average industrial operating conditions, the Iubricantshould be changed every 2500 hours. of operationor every 6 months, whichever occurs first. Drain reducerand flush with kerosene, clean magnetic drain plug andrefill to proper level with new lubricant. Caution: Toomuch oil will cause overheating and too little will resultin gear failure. Check oil level regularly.Under extreme operating conditions, such as rapid riseand fall of temperatures, dust, dirt, chemical particles,chemical fumes or oil sump temperatures above 200” F,the oil should be changed every 1 to 3 months dependingon severity of conditions.Table 1 - Oil VolumesNOTE:Pour point of lubricant selected should be at least10” F lower than expected minimum ambient startingtemperature.Extreme pressure (EP) lubricants are not recommendedfor average operating conditions.Special lubricants may be required for food and drugindustry applications where incidental contact with theproduct being manufactured may occur.

However,if the customer has access to an arbor press,equipment for heating and shrinking bearings and gearson shafts, and the tools normally found in a maintenancedepartment, the Screw Conveyor Drive speed reducer caneasily be disassembled and reassembled by careful attentionto the following instructions.Cleanliness is very important to prevent the introductionof dirt into the bearings and other parts of thereducer. The oil seals are of the rubbing type and considerablecare should be exercised during disassembly orreassembly to avoid damage to the surfaces on whichthese seals rub. Any sharp edges on the input shaft oroutput hub should be covered with adhesive tape orpaper before performing any work on the unit. Nicks andburrs on surfaces of the input shaft or output hub shouldbe removed.ORDERING PARTSWhen ordering parts specify Screw Conveyor Drive Sizeand Serial No., part name, part number and quantity.Parts that must be pressed from shafts or output hubshould be removed before ordering parts. This assuresthat those parts, if damaged during pressing operation,will be replaced. Do not press against the outer race ofany ball bearing.It is recommended that when a pinion or gear is replaced,its mating gear or pinion be replaced also. Thisinsures that the gear teeth will mesh properly. If the largegear on the output hub must be replaced, it is suggestedthat an output hub assembly, consisting of a gear assembledon an output hub, be ordered to secure an outputhub with undamaged surfaces on which the oil seals rub.However, if the old output hub is to be used, carefullypress the gear and bearing cones off. Thoroughly examinethe area under the oil seals for scratches or any otherdamage resulting from the pressing operation. To preventleakage at the oil seals, the rubbing area must be smooth.Replacements for the oil seals should be ordered, dueto the probability of these parts being damaged duringdisassembly.442-40If replacing an output hub bearing, output hub orreducer housing, it is advisable to order a set of outputhub shims because the adjustment of the output hubbearing will be affected.REMOVING SCREW CONVEYOR DRIVE PROM THE TROUGHENDDisconnect any electrical power to the drive. Drainlubricant .from reducer. Uncouple drive shaft and’screw.Remove nuts from trough end studs.

Position reducer on its side and remove all bolts.Gently tap the output hub and input shaft with a softhammer (rawhide not lead hammer) to separate thehousing halves. Open housing evenly to prevent damageto the parts inside.3. Lift shaft, gear and bearing assemblies from housing.4. Remove input shaft, output hub and adapter seals.Remove output hub seal carrier and shims. Remove outputhub bearing cups from housing.5. Clean all parts in solvent, inspect for damage andcoat with oil.REASSEMBLY1. Output Hub Assembly: Heat gear to 325 to 350’ F.to shrink onto output hub. Heat bearing cones to 270 to290” F. to shrink onto hub.2. Countershaft Assembly: Shaft and pinion are inte-gral. Press gear and bearings onto shaft. Press againstinner (not outer) race of bearings.3. Input Shaft Assembly: Shaft and pinion are integral.Press bearings on shaft. Press against inner (not outer)raceof bearings.4. Drive the two dowel pins back into position in theright-hand housing half (adapter mounting side). Placehousing half on blocks to allow clearance. Put the outputhub bearing cup in place, make certain that it is properlyseated in the housing..

5. Mesh output hub and countershaft together and placein housing half. Place input shaft assembly in housinghalf. Tap lightly with a soft hammer (rawhide not leadhammer) until bearings are properly seated in housing.Make sure that the snap rings on the O.D. of the bearingscome into contact with the housing.6. Clean housing flange surfaces on both halves, makingsure not to nick or scratch flange face. Place a new beadof gasket eliminator on flange face and spread evenlyover the entire flange leaving no bare spots. Note: Ifreducer was originally supplied with a housing gasketdo not use gasket eliminator. Reorder gasket per partnumber given in parts list.7. Place output hub bearing cup in other housing half.Make sure cup is properly seated in housing. Place housinghalf in position over dowel pins and tap with a softhammer (rawhide not lead hammer) until housing halvesare together. Install housing bolts and tighten evenly. Thefinal wrench torque for housing bolts is listed in table 3.8. Install the output hub seal carrier and the shimsremoved at disassembly. Tighten carrier cap screws whilerotating the output hub to make sure the bearings do notbind. If the bearings start to bind, add more shims.Torque, the carrier bolts to the value shown in table 3.Attach an indicator to the housing and set the gage onTable 3 - Bolt Tightening Torque Valuesthe top end of the output hub. Insert a pry bar underother end of the hub and force it upward. The axialplay of the output hub will be given by the indicatorreading. Add or remove shim stock to attain a readingof from .OOl” to .003”. Remove seal carrier and placea x” diameter bead of Dow Corning RTV732 sealant’onthe face around the I.D. of the last shim (sealant is tobetween shim and reducer housing). Reinstall outputseal carrier and tighten carrier screws to torque shownin table 3.9. Install oil seals. Extreme care must be observed wheninstalling seals on input shaft and output hub to avoidcontact with any sharp edges. This danger of damageand consequent oil leakage can be decreased by coveringall sharp edges with adhesive tape or paper before install-ing seals. Chamfer or de-burr housing bore if end of boreis sharp or rough. Fill cavity between lips of seal withgrease. Seals should be pressed or tapped evenlyplace with a soft hammer (rawhide not lead hammer)applying force only on the outer edge of the seals.slight oil leakage may be evident at the seals duringinitial running in, but will disappear unless seals havebeendamaged.10.
