BERKEL MODEL 705 - SPECIFICATIONS CONSTRUCTION: Corrosion resistant, steel frame, stainless burnadized aluminum housing.
S6151-DL-MMM-010 OVERLOADING The machine may jam from overloading or by a piece of bone accidentally fed into the blades. If this should happen: 1. Turn off machine immediately so as not to burn out motor or cause damage to gear box. 2. Unplug power cord. 3. Disassemble blades. Inspect for bent blades. 4. Remove obstruction, clean, inspect and reassemble. TENDERIZER GROUP The tenderizer group is the Assembly most often in need of your attention.
S6151-DL-MMM-010 1. Disassembling Tenderizer Blade Assembly a. Mount shaft upright in bench vice at the clutch end. b. Remove complete screw assembly bearing. c. Remove blades (3275-0014) and round hole spacer (3375-0164 (1)) and square hole spacers (3375-0165 (41)) down through blade(s) to be replaced. Note direction of the notch of the last blade removed. 2. Reassembling Tenderizer Blade Assembly Blades are placed on shaft staggered at 180 degrees.
S6151-DL-MMM-010 SERVICE NOTE: On some Assemblies you may find a thin metal shim washer. If new spacers are used, you will probably NOT have to use this shim washer. B. BLADE SHAFT ASSEMBLY REPLACEMENT (4575-0059 front, 4575-0061 rear) bly should only have to be replaced if the gear teeth or shaft have been damaged. The blade shaft assem- 1. Disassemble blades and spacers as described in previous section. 2. Replace a new shaft (front or rear). NOTE a.
S6151-DL-MMM-010 D. STRIPPER PLATE On occasion you will find that the Stripper Plate has been damaged. If badly bent or if teeth are missing replace. If teeth are bent out of line they can usually be straightened by hand or with pliers. CAUTION Make sure that spacing between teeth is accurate so there is no interference with the cutting blades. If problem continues replace with a new stripper plate. SAFETY COVER (9234-0020) If the cover is broken, replace as entire unit. A. MAGNET 0035 sealant.
S6151-DL-MMM-010 NOTE In some assemblies there are spacers behind the magnet. The magnet should rise slightly above the surface of the magnet well of the cover. B. PIN ASSEMBLY The Pin Assembly knob on the 705 is staked onto the pin and ordinarily should not need replacement. If replacement ever is needed, the knob should be screwed down even with the head of the cover pivot pin (3375-0156) and then staked in place to avoid the possibility of the knob working free and failing into the cutting blades.
S6151-DL-MMM-010 6. Check electrical supply to and from capacitor. If capacitor is not operating - replace.

S6151-DL-MMM-010 B. MOTOR REPLACEMENT If rest of electrical system is working but motor does not operate, DISCONNECT POWER SUPPLY AND REPLACE MOTOR: 1. Disassembly: a. Remove bolt that holds motor support brackets in place and remove brackets. b. Lift entire motor, adaptor assembly and gear box from lower housing as one unit and set on bench. c. Unscrew set screw from gear box end of flexible coupling. d.
S6151-DL-MMM-010 2. Re-assembly a. Replace coupling and set screw on new motor shaft, mount motor on the adaptor assembly and replace set screw on gear box shaft. b. Re-install complete unit, reconnect electrical leads to micro-switch and capacitor. Reconnect ground wire. c. Plug unit into wall outlet and test by manually pressing magnet switch. NOTE Always check the gear box grommets (2275-0208) whenever you have the upper housing off.
S6151-DL-MMM-010 e. Apply gasket sealant (Loctite No. 510) to edge of lower housing, place upper housing in place and re-install socket screws and caps in lower housing. C. ON-OFF POWER SWITCH (2675-0015) To replace the ON-OFF power switch: • Remove the upper housing assembly. • Remove wiring from switch. • Remove 4 bolts that hold switch to lower housing. •Drop switch down through opening and remove the switch boot (3675-0050).
S6151-DL-MMM-010 • Install new switch. Make sure that OFF position is toward the front. • Re-install the switch boot and position switch up through lower housing. • Re-install 4 bolts and wiring. D. MICRO-SWITCH ADJUSTMENT (4175-0020) The plastic tenderizer neck is fitted with a magnet that interlocks with the magnet on the micro-switch located inside the right side of the machine case. The micro-switch is mounted in slotted holes for adjustment.
S6151-DL-MMM-010 FLEXIBLE COUPLING REPLACEMENT (2375-0095) This flexible coupling is designed to break if extreme torque is encountered by the cutting blades jamming. If it breaks, you will have the motor running freely and either no power delivered to the gear box, or there will be erratic and jerky action of the cutting blades. • Remove upper housing and visually inspect. • Replace as previously described.
S6151-DL-MMM-010 The gear box housings are fitted at the factory using Loctite No. 510 Gasket Sealant (1875-0035) to form the gasket. Under the normal process of taking out the two dowel pins (2275-4221), step No. 6, the two halves will loosen. Loctite No. 510 is used only on the housing halves. Loctite No. 290 is used on all other parts per directions that follow. A. Gear Box Disassembly 1.
S6151-DL-MMM-010 4. Press out 2 idler shafts (3375-0669) using a 1/2″ arbor press. Exert steady, firm pressure until the shafts drop through. Catch the shafts with your hand so they will not be damaged by dropping on a hard surface. 5. Press out the drive-gear assembly shaft (4375-0132) from the back side of the gear box (the side opposite the housing), complete with gears, using a 5/8″ diameter arbor press. NOTE On occasion the back bearing will break loose and drop with the assembly into the housing.
S6151-DL-MMM-010 6. Press 2 clutch assemblies about .06″ using the arbor press and a pin of large enough diameter to completely cover gear teeth. This will break them loose from the outer bearings that are sealed with Loctite No. 290. 7. Break loose the 2 dowel pins (2275-4221), using a punch slightly smaller than the diameter of the pins. CAUTION If you use a punch considerably smaller than the correct diameter, you will distort the pins and they cannot be reused.
S6151-DL-MMM-010 8. Once the pins are driven out, the two halves of the gear box housing can be separated. Lay the gear box on its back and lift off the front housing and lift out the fiber gear assembly cluster (4575-0285) and the metal gear assembly cluster (4575-0286) next to it. 9. Now press alternately one clutch assembly and then the other from the rear, using a punch that completely covers the outer race of the bearing, (parts 4375-0134 and 4375-0135) until they are freed and fall out. 10.
S6151-DL-MMM-010 Rotate the bearings with your fingers. If there is an irregular rotation, if they are tight and binding or if they have a granular feel, as if there is sand in the bearings - it probably indicates that the bearings have been damaged in removal and must be replaced. B. GEAR REPLACEMENT • If either of the gear cluster assemblies (4575-0285 or 4575-0286) are to be replaced, you would order the respective assembly.
S6151-DL-MMM-010 1-25
S6151-DL-MMM-010 C. Gear Box Reassembly • Remove all rear bearings and set aside for cleaning. Clean all gears and the housings with a cleaning solvent. (No. 111 Tri-chloralethylene) NOTE IT IS ESPECIALLY IMPORTANT THAT THE MATING SURFACES OF THE HOUSINGS AND THE BEARING RACES BE PERFECTLY CLEAN, OTHERWISE THE LOCTITE SEALANTS WILL NOT FORM AN EFFECTIVE GASKET.
