Assembly:
Step 1
Apply Loctite #7649 Primer or equivalent to threads on turbine cover and collet guard.
Important: Provide good ventilation and allow solvent to evaporate until surfaces are completely dry.
Step 2
Press new 51662 Air Bushing into turbine cover.
Important:Allow 1/16" (~1.5 mm) of bushing to jut out of turbine cover. Use 51656 Turbine Base as a "JIG" to preset air bushing depth.
Set turbine cover aside until STEP #13.
Step 3
Use "RAISED INSIDE DIAMETER" of 96418 Bearing Press Tool,
and 96232 Arbor
Press to install 51651 or 51686 Bearing onto drive shaft.
Step 4
Install 51678 Turbine and 51691 (35K), 51692 (50K), or 51675 (60K) Governor.
Step 5
Assemble turbine base, turbine, governor and top plate to make up the motor unit.
Hold the motor unit together, apply a small amount of Loctite #222, or equivalent
on threads of 51655 Top Plate.
Carefully, fasten motor unit onto drive shaft.
Step 6
Insert 51694 Pin through cross-hole in drive shaft.
Fasten drive shaft in vise with aluminum or bronze jaws.
Use 96408 Top Plate Wrench and torque wrench to tighten top plate.
Torque to 4.5 N·m/~40 lb in.
Step 7
Apply a small amount of Loctite #609, or equivalent to outside diameter of 51651 or
51686 Bearing.
Install 51661 Wave Spring and drive shaft assembly into housing.
Step 8
Apply a small amount of Loctite #609, or equivalent to outside diameter of 51685 Bearing.
Use "RAISED OUTSIDE DIAMETER" 96419 Bearing Press Tool and arbor press to install 51544 or 51685 Bearing.
Important: Once bearing is installed, invert 96419 Bearing Press Tool with "RAISED INSIDE DIAMETER" toward inside race of bearing.
Apply a slight load on bearings with arbor press.
Check fit and rotation of bearings.
Important:
Use a pipe-cleaner to wipe Loctite from housing threads.
Step 9
Insert 51694 Pin through cross-holes in housing and drive shaft.
Remove assembly from arbor press and fasten in vise, with threaded end of drive
shaft pointing up.
Install 94984 Spacer, with larger diameter toward 51544 or 51685 Bearing.
Step 10
Apply a small amount of Loctite #222, or equivalent just above 94984 Spacer.
Use torque driver and 96479 Extension Retainer Wrench to install 51548 Bearing
Retainer.
Torque to 2 N·m/~18 lb in.
Step 11
Apply a small amount of Loctite #567, or equivalent to threads of collet guard.
Use a 14 mm crow-foot and torque wrench to install collet guard onto housing.
Torque to 4.5 N·m/~40 lb in.
Step 12
Install collet insert.
Use 95731 Wrench (8 mm) to install 51657 Collet Cap.
Remove pencil grinder from vise and remove 51694 Pin.
Important:
Do not over tighten collet assembly.
Step 13
Install 51276 Hose onto first barb of turbine cover.
By hand, fasten turbine all the way onto housing. Turn clockwise.
Slightly loosen turbine cover from housing until drive shaft turns freely.
Connect 51277 Air Hose to air supply.
Push 51665 Valve to "ON" position. Allow motor to run up to speed.
Important:
Air bushing "Wear-In" time will vary. If motor does not initially run to
speed, continue to tighten and loosen turbine cover until maximum RPM is
achieved.
Push 51665 Valve to "Off" position, and disconnect tool from air supply.
Step 14
Install 51684 Muffler.
Apply a small amount of Loctite #567 to threads of turbine cover.
Step 15
Insert 51694 Pin through cross-hole in housing and drive shaft and fasten in vise.
Use 94605 Pin Wrench and torque wrench to tighten turbine cover.
Torque to 14 N·m/~125 lb in.
Important:Allow Loctite Threadlockers and Retaining Compounds to cure/fixture for 30
minutes before checking RPM. Supply 90 psig. (6.2 Bar) maximum operating air
pressure at air inlet of tool. Use tachometer to check maximum operating speed
without an accessory in collet. Push 51276 Hose all the way onto turbine cover.
