Motor Assembly/Disassembly Instructions - Dynorbital-Spirit
Important: Manufacturers warranty is void if tool is disassembled before warranty expires.
A Full Service Repair Kit P/N 57098, is available which includes special repair tools for correct disassembly/assembly of the sander.
To Disassemble:
1. Disconnect sander from air supply.
2. Invert the sander, and place the 57092 Repair Collar (supplied in the 57098 Full Service Repair Kit) around the housing and secure in a vise. Padding
can be used on the vise jaws to protect the housing. Important: Do not over tighten the sander in the vise. If the sander is held too tight the
removal of the lock ring and air motor will be difficult.
3. Remove back-up pad with the 50679 26mm Open-end Wrench (supplied with the sander).
4. Insert 56058 Lock Ring Tool (supplied in 57098 Full Service Repair Kit) into the corresponding tabs of lock ring. Loosen the 59058 Lock Ring
turning it counterclockwise.
5. Remove the 59058 Lock Ring from the air motor assembly (3/32" and 3/16" dia. orbits only).
6. Remove 98463 Retaining Ring from motor assembly.
7. Fasten a 2 in. bearing separator (P/N 96346 available) around the 59051 Cylinder just below the 59077 Rear Bearing Plate. Place the air motor
assembly in a #2 arbor press (P/N 96232 available) so that the separator is resting on the table of the arbor press and with the balancer pointing down.
8. Use a flat nose 3/16" dia. drive punch as a press tool. Place it against the small end of the motor shaft balancer and push the shaft out of the
upper 58368 Bearing.
9. Remove the rotor, vanes and rotor key from the motor shaft balancer.
10. Again fasten the 2 in. bearing separator between 58368 Bearing and the top of the balancer. Rest the separator on the table of the arbor press
and push the motor shaft balancer out of the 58368 Bearing. Remove 59057 "Top Hat" Seal and 59083 Felt from 59076 Front Bearing Plate.
11. Disassemble the balancer assembly as follows:
a.) Place motor shaft balancer assembly into a soft jaw vise. Using a thin screwdriver, pick out the end of 95630 Snap Ring and remove. This will
loosen the balancer assembly.
b.) Screw the threaded portion of the 56056 Bearing Puller (supplied in 57098 Repair Kit) into the 57069 Balancer Shaft and heat the outside of the
motor shaft balancer to approximately 200° F (approximately 10 seconds with a propane torch). Now, using the slider weight, pull
the assembly out.
c.) Press off 56052 Bearing with a bearing separator and arbor press, remove 59084 V-Seal.
12. If during step 11, the 56052 Bearing remains in the motor shaft balancer, it can be removed by the heating the shaft balancer again and using either an
inside bearing puller or a blind hole bearing puller.
To Assemble:
Important: Clean and inspect all parts for defects before assembling.
1. Assemble the balancer assembly as follows:
a.) Install 59084 V-Seal onto the balancer shaft. Install with flexible lip of seal facing hex of balancer shaft. Be certain seal is pressed
completely over shaft step. See Drawing 1.
b.) Install 95360 Snap Ring between flange of 59084 V-Seal and hex of balancer shaft.
c.) Apply 1 drop of #271 Loctite
of the 57069 Balancer Shaft.
d.) Use the 57091 Bearing Press Tool to press 56052 Bearing with seal side toward hex of balancer shaft up to shaft step as shown in Drawing 1.
This is a firm press fit for proper retention of bearing.
2. Place the motor shaft balancer in a soft aluminum or bronze jaw vise with large end pointing up.
3. Apply 1 drop of #271 Loctite
assembly into the motor shaft balancer until 56052 Bearing is firmly seated at bottom. Squeeze 95630 Snap Ring into groove in motor shaft balancer
to complete the assembly. Remove from vise. Place 59058 Lock Ring onto the motor shaft balancer (3/8" orbit models only).
4. Place the 59083 Felt into the 59057 "Top Hat" Seal.
5. Install the 59076 Front Bearing Plate onto the motor shaft balancer, fitting it to the bearing, felt, and "Top Hat" Seal as is shown in Drawing 4.
