housing into a 9/16” collet. With the housing securely held, insert the raceway tool into
the raceway and unscrew.
STEP 10
Remove the vent plug from the housing. Like all threads on
this handpiece, turn counterclockwise to unscrew. Once the
plug is out, replace the o-ring (404072) in the rear of the housing.
STEP 11
To disassemble the turbine, place the drive ring raceway over the largest hole
on your work block (as shown). Then put your Lares disassembly tool
(00024L1) into the end of the motor spindle. Press the spindle and tool
through the raceway.
STEP 12
Now turn the partially disassembled raceway over (see picture). The front
motor bearing must be removed from the raceway. Use your Lares
assembly tool (00024L2) to punch the bearing out of the raceway. Always
replace these motor bearings when performing an overhaul. Place all of your dirty or
fouled parts in the ultrasonic cleaner.
