TM 5-3895-374-24-2Note: If motor mount, motor and sheaves are to beinstalled on reducer before mounting ScrewConveyor Drive to trough end, bypass step 2;perform steps 3 and 4, and then return to step 2.2. On sizes SCXT3, SCXT4, and SCXT5A use lifting tabto hoist the Screw Conveyor Drive into position. Slideshaft into screw and adapter over trough end studs.Only one set of adapter holes will fit over trough endstuds. If the mounted position of the Screw ConveyorDrive varies by 15’ from any of the four horizontalmounting positions shown in fig. 2, an incorrect set ofholes has been selected for coupling adapter to reducer.This can be corrected by removing adapter screws androtating reducer to its proper position. Reinstall andtighten adapter screws to torque specified in table 3 onpage 5. Install lockwashers and tighten nuts on troughend studs. Attach drive shaft to screw.3. Remove the three bolts from reducer housingrequired for mounting the SCD Motor Mount. Place themotor mount in position and install the three housingbolts supplied with the motor mount. Tighten bolts totorque specified in table 3 on page 5.4. Install motor, drive sheave and driven sheave so thatdriven sheave is as close to the reducer housing aspractical. Install V-belt and tension with the fouradjusting screws provided on the SCD Motor Mount.Install Belt Guard. Make required electrical connectionsfor 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 oxidationinhibited (R & O) gear oil-see lubrication tables.6. Retighten bolts and pipe plugs after a few daysoperation This prevents oil leakage.Fig. 3-Complete Drive.LUBRICATIONUnder average industrial operating conditions, thelubricant should be changed every 2500 hours ofoperation or every 6 months, whichever occurs first.Drain reducer and flush with kerosene, clean magneticdrain plug and refill to proper level with new lubricant.Caution: Too much oil will cause overheating and toolittle will result in gear failure. Check oil level regularly.Under extreme operating conditions, such as rapidrise and fall of temperatures, dust, dirt, chemicalparticles, chemical fumes or oil sump temperaturesabove 200’ F, the oil should be changed every 1 to 3months depending on severity of conditions.NOTE:Pour point of lubricant selected should be atleast 10’ F lower than expected minimum ambientstarting temperature.Extreme pressure (EP) lubricantsare notrecommended for average operating conditions.Special lubricants may be required for food anddrug industry applications where incidental contactwith the product being manufactured may occur.Consult a lubrication manufacturers’ representativefor his recommendations.Table 1-Oil Volumes.page 3-782
