DISASSEMBLY

REASSEMBLY

The dual spindle attachment can be serviced without removing the complete assembly from the tool. Using the 4 mm hex wrench supplied with the unit, loosen both adjusting screws (45992) - NOTE: Alternately unthread adjusting screws approximately 1/2 turn at a time or unthread screws simultaneously to prevent dam- aging the unit.

After the body and components have been removed from the adapter, driving spindle (47757-302) and components can be re- moved from adapter. To remove bearing (32325) and/or gear (45991); remove retaining ring (45989), press bearing back on spindle to expose needle roller (45986) and remove roller to re- move gear. Remove bearing from spindle.

To remove gear (45996) and/or components, remove crescent ring (45997). Rotate spindle turret, and at the same time, pull back slightly on turret to locate alignment of spindle with notch in body (45999) and remove spindle assembly from body. To remove gear

(45996) from body, remove oil reservoir (46009) and nylon wash- er (45993) bending washer slightly to remove. Bearings (46602), spacer (45995) and washer (45994) are loose parts and will drop out. Do not disassemble spindle (46022). If necessary to replace a part, replace as complete spindle assembly (46022).

Pack bearings and coat gears with a good grade of bearing grease when assembling. Saturate oil reservoirs with a good mul- tigrade 10W/30 oil.

Insert a dummy adjusting screw (45992) (or a shaft of the same diameter) thru adapter side of body to maintain alignment of parts to be assembled into body and assemble nylon washer (45994) to dummy screw. Assemble one bearing (46002), spacer (46995) and another bearing (46002) into gear (45996) and assemble gear to the dummy screw. Assemble nylon washer (45993) into body, bending washer slightly to insert into body, and assemble oil reservoir (46009) into body.

Assemble adjusting screw to spindle assembly (46022) and as- semble nylon washer (45994) to adjusting screw. Assemble the spindle assembly into body while holding adjusting screw in align- ment with dummy screw to maintain pans alignment and using adjustment screw to push the dummy screw out of body. NOTE: Align spindle assembly with notch in body to assemble. After as- sembling spindle to body, assemble crescent ring (45997) to ad- justing screw, securing screw to body.

Reassemble driving spindle (47757-302) and components and the body (45999) and spindle assemblies (46022) to adapter (47757-298) in the reverse manner of disassembly.

RECOMMENDED METHOD FOR HOLDING DRILLS IN SPINDLES

To properly hold drill bit in Collet and reduce the chance of slip- page, a flat must be ground on the shank end of the bit. The flat should be approximately 5/16” (8 mm) long and the depth should be 1/3 of the bit diameter. NOTE: If bit is too large to fit into locking insert (smaller capacity dual spindles do not have insert), a square must be around onto the shank end of the bit.

Insert bit into spindle and into locking insert (where applicable) in- suring that one of the set screws locates squarely on the flat of the bit. Tighten Collet firmly, then tighten set screws. NOTE: DO NOT overtighten Collet. NOTE: Intent of set screws is only to keep bit from turning in Collet.
