  If you are unsure then all new inventory has the larger hole and allows for use on both the D3 series and D4 series.

  Nut, Shaft, D3/D2

  Item #: H306
  Availability: In Stock
  Condition: Used

  Price: $3.15 USD

  Quantity: 1 2 3 4 5 6 7 8 9 10+ Add to Cart

  This motor shaft nut is the same for all model D3C, D3A, D2A, D2, and D motor design. Reverse thread nut so be careful when installing and removing to be sure not to damage.

  Over tightening can cause the snap rings to be pressed out of their slots and cause a spacing issue which will cause the motor to bind.

  Motor Brush, D4/D3

  

  Brand: Rainbow®
  Manufacturer: Rexair, LLC
  Item #: R2421
  Availability: In Stock
  Condition: New

  Price: $20.34 USD

  Quantity: 1 2 3 4 5 6 7 8 9 10+ Add to Cart

  This item is sold each. If you need a pair to replace both sides on your motor, then please add a quantity of two to your cart.

  Original factory OEM carbon brush for the D4C and D3C Rainbow. Be sure to measure and confirm you are ordering the correct size. (.4955 or just less of 1/2 inch).

  Effective through serial number 7520714. The R5125 is the carbon brush that you need if your serial number is higher or if your measurement is larger. Check the "Related Items" tab for an R5125.

  * SELECT OPTION: This item needs to be "seated" for proper life expectancy. We use a variable transformer (variac) to seat the brushes. If you are unable, we offer this as an optional service.

  • Not properly seating in the carbon brushes can cause brush and commutator damage leading to costly maintenance and downtime
  • By properly seating in the carbon brushes, it allows you to use rated current almost immediately
  • Change all carbon brushes at one time
  • Vacuum excess carbon dust to prevent from reaching machine windings and bearings

  The M596 Seating Stone is only used to "clean up" the commutator of the armature and not meant to "seat" the brushes. If you are not exactly sure how to "seat" your carbon brushes, the service fee that we charge is well worth it in the long run.

  If you do not seat the motor brushes, you can expect about a one year life before they wear out.

  
  
  

• Not Applicable!

  Unfortunately this item is not obtainable in the U.S. or does not apply to the 110-120 volt version. If you have any questions, please Contact Us or call 800-523-0510.

  Spider, D4/D3, v2

  

  Brand: Rainbow®
  Manufacturer: Rexair, LLC
  Item #: R4101
  Availability: Discontinued
  Condition: New

  Price: Discontinued

  This item has had several upgrades over the years since it was first introduced with the Special Edition model D4C Rainbow.

  It was originally a gray color matching the original separator. Then it changed to a yellow-tan color that matches the current R4100 separator. Then if finally was redesigned from the cone shape to what it looks like today. It was also at that time when it became black in color. No matter which version you have, this is a direct factory OEM replacement.

  The spider sets under the separator and works directly with the separator. This spider and the R4100 separator was one of the upgrades that was done when the D4C Special Edition (SE) was introduced in 1990.

  This has to be purchased as a kit if you are replacing an original R1976 spider from a model D4C or D3C Rainbow. If you have an R1976 currently, then order an R4100, R4101 and H555.

  Nut, Spider, D4/D3

  

  Brand: Rainbow®
  Manufacturer: Rexair, LLC
  Item #: H526

  Condition: New

  The armature shaft nut is installed after the spider and should almost always be replaced anytime any repair has been done. Be sure to clean threads on the armature shaft with a wire wheel or wire brush if that is all that is available.

  Nut, Separator, D4/D3

  

  Brand: Rainbow®
  Manufacturer: Rexair, LLC
  Item #: H524
  Availability: In Stock
  Condition: New

  Regular: $5.07 USD
  Online: $3.12 USD

  Quantity: 1 2 3 4 5 6 7 8 9 10+ Add to Cart

  This nut holds the separator in place on all D3 and D4 model Rainbows.

  For a short period on the model D4, this nut had an open top and allowed you to use a flat screwdriver to hold the motor in place. The problem with this design was that it allowed water to get on the threads and seize the nut to the motor shaft. Replace if you are able to see the end of the motor shaft in your machine.

  This nut fits the older style R312 separator. Be sure to look at the image closely as the other types of separator nuts have a flat base and do not work correctly with the R312 plastic separator. If you have a metal separator, then please order an H555 that has the flat base.

  This standard separator nut for the R4100 separator comes factory standard on the model D4C SE (Special Edition) Rainbow. Do not use on the R312 separator that comes standard on the original D4C or older units.

  Separator, D4/D3/D2, v1

  

  Brand: RainVac
  Manufacturer: Essco, Inc.
  Item #: R312
  Availability: In Stock
  Condition: Used

  Price: $26.55 USD

  Quantity: 1 2 3 4 5 6 7 8 9 10+ Add to Cart

  This item fits model D4C, D3C, D3A, D2A, D2, and D. On the model D4C and D3C, you must have the original R1976 spider that came standard for this to fit correctly.

  On March 28th 2002, Rexair discontinued production on this item and also the matching R1976 spider. We realize that many people still have the model D4C and D3C Rainbow system, so we offer used as a solution.

  If you need to replace both separator and spider, then you would order item numbers R4100, R4101, and H555. These three items are a direct replacement and also an improvement.

  The separator separates the air from the water. The water is thrown back into the water pan and it allows clean air to go up through the motor and out the exhaust. Be sure to take off and clean periodically as it can become clogged with dirt and will reduce your performance.

  If you have a plastic separator that does not have a metal band around the outside edge, at some point the separator may break into pieces during use. The metal band was added to prevent this issue from occurring.

  Separator, D4/D3, v2

  

  Brand: Rainbow®
  Manufacturer: Rexair, LLC
  Item #: R4100

  The separator is one of the most important parts on the Rainbow cleaning system. It throws the water back into the water pan and allows clean water washed air to travel up through the motor and out the exhaust. Be sure to take off and clean as it can become clogged with dirt and debris.

  If your model is the D4C SE (Special Edition) with the R4101 spider, then this is the current revision. If you have a D4C or D3C, then you would also need to order the R4101 and H555.
