The following is a procedure for disassembling the entire cutting unit(Figure27).Note that individual spindles and related parts can be removed without disassembling the entire cutting unit(for example,the circular knife spindle and stripper plate can be removed without disassembling any other part of the cutting unit). Figure 27-Cutting unit. (1)circular support assembly, (2)impeller (3)crosscut knife spindle, (4)slice gate , (5)stripper plate, (6)slicing knife (7)slice adjustment knob, (8)adjustment nut1.Ower source must connected to machine and turned on.Turn the power disconnect/lockout switch to the “O”(OFF)position and lock out.Allow machine to come to a complete stop,then press the “I”(start)button and hold for two seconds to verify that the machine will not start.After the green guard locking switch status lights illuminate(when all rotating machine parts are idle)unfasten the draw latch connecting the feed cover door and support housing.Open the feed cover door.2 .Slide protective sleeve provided with the machine over the crosscut spindle(see “Crosscut Knife Spindle Assembly”,page 80).CAUTION:The following step in this maintenance procedure repuires that the cutting parts be rotated.Use the impeller to rotate the parts.The impeller should only be grasped near the bottom to avoid contact with slicing knife!3 .Remove the circular support assembly which contains the circular spindle assembly .Rotate the impeller by hand (grasp near the bottom) until the line etched on the circular support assembly aligns with the line on the end of the circular spindle(Figure 28).The open side of the drive coupler must face out(Figure 39,page 45).This can be viewed by looking in the space between the circular support and the support housing.Remove the two locking nuts and pull the circualar support assembly straight out and off of the machine (Figure 29).Place the support assembly on a work surface in a safe palce.Figuar 28-Aligning circular knife spindle.

(1)Cricular support assemblyCAUTION: Always carry and store the circual support assembly containing the circular spindle so that exposed knife edges do not present a safety hazard.The crosscut knife spindle should be removed from the machine if replacing more than two crosscut knives and if removing the slicing knife holder.Proceed to step #4 to remove crosscut spindle.Replacement of crosscut knives:To replace just one or two knives ,back off screws approximately two turns and pull retaining ring out .Carefully lift knife from slot(Figure 30).Replace knife making sure knife is seated in clean knife slot,with all knives is facing the same direction.Use the torque wrench provided with machine and tighten retaining ring screws to 20 inch/pounds(2:2 newton-meters).To replace more than two knives ,remove crosscut spindle from the machine as outlined below.See page 48 for maintenance information.Figure 30-Replacing crosscut knives. (1)Retaining ringCAUTION:The crosscut spindle is heavy ,weighing approximately 60 pounds(27 kg).Use appropriate lifting techniques.4 .Use the “L” handle wrench provided with the machine and remove two of the three screws that hold the spindle to the machine.Loose the third screw but to not remove.5 .Install the shaft extension tool provided with the machine .Guide the shaft extension tool in place over the stud in the crosscut shaft and tighten until it stops against the shaft (Figure 31).Figure 31-Loosening crosscut knife spindle fasteners. (1)Protective sleeve, (2)shaft extension tool ,(3)”L” handle wrench6 .Remove the remaining fastener that holds the spindle .Slide the spindle over shaft extension tool to remove from the machine (Figure 32).Carefully set the spindle aside on a surface that will not damage the knives.Figure 32-Removing crosscut knife spindle. (1)Shaft extension tool, (2)Crosscut knife spindle7 .Remove the stripper plate and stripper plate spacer.Three bolts hold the stripper plate to the stripper plate spacer on the slice gate.Three screws hold the spacer to the case(Figure 33).If the spacer is difficult to remove,use the stripper plate fasteners as jacking screws in the holes on the spacer used to attach the stripper plate.Figure 33Using stripper plate screws to remove stripper plate spacer. (1)Stripper plate spacer. (2)stripper plate fastener(used as jacking screw)8 .Remove the slicing knife insert by using a screwdriver or similar tool that will fit in the hole in the exposed handle end of the slicing knife (Figure 34).Carefully pull the knife from the slicing knife holder.Note that some cutting applications may use the slicing knife that is integrated with the knife holder(no replaceable insert).That knife is removed in the same manner as the slicing knife holder as described below.Figure 34-Removing replaceable slicing knife insert. (1)Screwdriver, (2)Slicing knife insert, (3)Slicing knife holder, (4) Fastening post9 .Remove the slicing knife holder.The fastening posts act as fasteners to secure the knife holder to the case.If the machine is being used as a strip cutter, the circular support assembly may not be in use, in which case the slicing knife holder is held by hex head cap screws. 10 .The slice gate generally dose not require removal unless changing between straight and crinkle slice gates.If removal is required ,proceed as follows.11.Remove adjustment nut.(see Figure27,page 28.)From within the gear compartment, remove the tightening rod.Push back on the tightening rod from binding as it is removed(Figure 35).Remove the slice gate guard ,which is by the tightening rod.Figure 35-Removing tightening rod for slice gate . (1)Adjustment block, (2)Tightening rod12 .Remove four fasteners and washers on the lower portion of the plate(Figure 36).Remove the slice gate.Figure 36-Removing slice gate .(1)Hinge plate, (2)Slice gate The impeller generally dose not need removal .If removal is required:CAUTION:The impeller is heavy ,weighing approximately 77 pound(35 kg).Use appropriate lifting technipuse.13.

(1)Side ,(2)Top4.Clamp the end of the spindle in a soft jaw vise.(Soft jaws are necessary to protect the precision parts.)5.Remove spindle nut ,turning clockwise (the nut is a left hand thread) using the wrench supplied with the machine (figure 43).Remove knives and spacers.Figure 43-Using spindle wrench to loosen and tighten spindle nut.INSPECTIONAll parts should be cleaned, inspected for serviceability, and repaired or replaced if necessary.Spacers ,Spindle and spindle nut:Check for burrs and hone if necessary,but be careful to remove only the burr. Knives:Replace any that are bent or have large nicks.For detailed information on knife care and sharpening,see pages 57-59 and refer to the “SHARP” bulletin provided with the machine. Spindle support:Check for damage or scoring in the bearing areas.Check all mating surfaces for nicks or burrs;use a hone to remove any burrs that may prevent parts from seating properly.Bearing replacement:1.Remove the bearings.Remove both sides of the support assembly.Support one side in an arbor press.Using the seal seating tool supplied with the machine,press the worn bearing out and discard(Figure 44).Repeat with the remaining side.Figure 44-Removing the circular knife spindle bearings.(1)Side, (2)Bearing, (3)Bearing Seating ToolNOTE:Replacement bearings should be purchased from Urschel Laboratories.The inner race of the bearings have a slight taper to mate with tapered areas on the circular knife spindle.2.Apply a thin layer of grease(Royal Purple Ultra-Performance Clear FDATM )to the bearing areas of the circular support assembly sides.3.Press new bearings into the sides with the bearing searing tool and an arbor press. One side of the outer race of the bearing has marking. The unmarked side of the bearing should be placed into the side,to be pressed against its seat,and the marked side should be against the side,to be pressed against its seat,and the marked side should be against the tool.with the bearings installed,the markings on the outer races should be visible.When the support is assembled, the marked outer race is facing in toward the circular spindle.With the bearings installed in this manner,the shaft of the circular spindle enters the inner race of the bearing at the wide end of the taper. 4.Attach one side to the top of the circular support assembly.Install the side with the alignment marks first.Replace the circular knife spindle,than install the remaining side of the support assembly.REASSEMBLY1.The circular knife spindle begins and ends with a knife. Alternate spacer and knives to obtain the size cut desired.See “Circular Knife Spindle Assembly”,page 79.NOTE: Never start or end the assembly with a space.Feed discs may be substituted for circular knives for certain applications. 2.Lubricate spindle threads and replace the nut on the spindle.The end of the nut with the recessed surface should face the knife.Make sure the last knife is not in the threaded portion of the spindle before tightening the nut.3.Place the spindle assembly in the circular support and replace and tighten the two fasteners on the support end.Install the support in the machine or store in a safe place. See “Reassembly”,page 45.DISASSEMBLYWARNING:Cutting parts are sharp and can cause injury! Wear protective gloves when handling cutting parts.1.With protective sleeve over crosscut spindle,remove crosscut knife spindle from machine. See”Disassembly”,pages 38-40.place on a level work surface that will not damage the knife edges.Remove the protective sleeve.2.Remove the retaining ring. Two retaining rings hold the knives in place on the spindle. rings hold the knives in place on the spindle. Generally, only the ring that faces away from the machine needs to be removed. This end can be determined by looking at the mounting holes inside the spindle. The mounting surface with the chamfered holes mounts against the crosscut shaft. Remove the retaining ring on the opposite end (Figure 45). If the attached ring has product build-up, remove it also and clean thoroughly.Figure 45 - Crosscut knife spindle disassembly.
