Dissassembling the main motor unit is fairly easy. There are a few small parts so make sure you put them safelly so they will not fall into the vent on the floor or get eaten by curious cat. The motor itself is not as easili servbiceable as earlier model Rainbow sweeper motors. Parts such as armature, field, upper fan case housing, bearing bridge, bearings - are NOT available from manufacturer. If there is something wrong with those parts - you will need to get a new motor. We sell them for a bit over 200 dollars so this is not very bad but still - I wish manufacturer would have allowed us to service the motors.

Rainbow e series vacuum cleaner motor (main motor unit) dis assembly and assembly sequence

Removing HEPA filter cover

1

Removing HEPA filter cover:

Newer style filter cover - In the picture you see newer style filter cover that is held in place with 2 tabs. Release them with flat screwdriver and the cover will pop off

Older style filter cover - older style cover is attached to the main housing wit 4 phillips screws. 2 of them are clearly visible near the bottom of the unit and 2 more are concealed under cord caddy. Use flat crewdriver to remove cord caddy and under it you will fing 2 more screws.

Removing side panels

2

Use smaller flat screwdriver to release tabs of the Rainbow clear side panels (top of the panel)

Rainbow e series cap screws

3

When clear side panels removed 4 or 6 screws total will be accessible. These screws hold unit cap to the main Rainbow e series housing

Access Rainbow motor filter

4

Under the cap you will see motor air cooling filter.

on off switch harness plug

5

Pull the plug off the On/Off switch

Removing rainbow e series cord

6

Remove strain relief from the cord.

Cord wire terminal

7

Use small screwdriver or pin to push on the wire terminal metal lip to release wire from the plug.

Skip this step if you are not going to wash the cap or remove the cord. Ocassionally the terminal lip gets broken and to ensure proper contact with the switch you may have to purchase a new cord or if you are really savy in such work - replace the wire terminal

wire treminal lip

8

This is the lip that holds the terminal in the harness plug.

Removing e series on off switch

9

If you need to remove the switch you will need to push on 4 tabs from the inside of the cap (blue arrows), while pulling on the switch (red arrow) (or pushing the switch from inside).

Rainbow nozzle receptacle harness

10

Use flat screwdriver to pull the harness of the power nozzle cord receptacle

Rainbow e series safety switch

11

Disconnect two wires from safety switch

e series motor retainer ring

12

4 more phillips screws that hold motor retainer ring.

e series latch baffle

13

2 phillips screws on the bottom of the unit are holding each baffle with latch. Note that one baffle has the safety switch and tiny actuator plug that is very easy to loose. Note how the plug is installed.

Removing e series rainbow latch

14

Only when baffles are removed you will gain access to latch pins. You will need to push on smaller diameted end to get the pin out so you can remove the latch.

Skip this step if you do not need to replace the latch

Rainbow e series face plate

15

Front bottom of the unit - 2 screws that hold the faceplate to the unit

Rainbow e series front plate

16

2 more screws on the top.

Rainbow e series intake

17

Pull up and away to get the faceplate off the unit.

You may have tu cut through the glue that is between the gasket and the intake (part of the faceplace). I would not remove the faceplate unless you need to install new one. There is no or very little dust under it so it is not worth the trouble.

Motor is glued to the gasket and gasket is glued to the main housing. You will need to use come force to tilt the motor to the side while tearing the gasket off the housing. See if you can save the gasket. Old style gaskets are not available anymore and you may need to put in some time to install the new style gasket on your Rainbow sweeper. Gasket and more details about installing it HERE .
Remove spider nut

18

You will need 1/8 hex key to hold the armature and 1/2 wrench for the nut.

Removing e series spider

19

When nut removed - spider will come off (on older motors there is washer between spider and fan (spider of older motors with washer is made out of white plastic) .

Removing fan case clips

20

Remove 4 clips holding lover fan case housing .

E series fan / impeller

21

Lower housing will come off exposing the only fan blade .

upper baffle e series rainbow motor

22

Under the fan there is a spacer and plate attached to the upper fan case housing with 4 screws. Older style (AME) motors had this plate glued to the upper housing. There is no need to remove it unless you really want to clean under it. Usually is is not worth it.

E series motor disasembled

23

This is how it looks when everything is removed..

Remove motor cap

24

To acces motor brushes you will need to remove motor cap.

Rainbow eseries motor brushes change

25

This is new style (GSE) motor brush attached to the bearing bridge with one screw. Older (AME)style motor brushes with brass housing had a clip with 2 screws.

Would not recommend disassembly beyond this point. Any parts that could further be removed are not available from Rainbow e series manufacturer to purchase. To take bearing bridge off you will need to remove the motor cooling fan. it is possible to remove it so it can be reused but ocasionally it breaks and manufacturer does not sell them separatelly.
