D4 Motor / Water Pan Gasket

Rainbow SE Separator Nut, Model D4/D3, v2

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.

Rainbow D4C 120 Volt Main Motor

Over the years the motor wears and sometimes it is best to service, other times it is best to replace. Depending on the overall condition and what problem you are experiencing, this decision is sometimes easier than others.

The current version motor has had numerous improvements and revisions over the years. From upgraded carbon brushes, nickel plated armature shaft, to a new spider design that works with the improved R4100 separator. If you currently do not have the R4100 "SE" version separator, then it might be a good idea to add that as well as an H555 separator nut. Both of these items are in the "Related" tab.

This motor is the original OEM factory motor for the model D4C SE (Special Edition) and D4C Rainbow vacuum.

Rainbow D4 and D3 Version 2 Separator

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.

Rainbow Version Two D4 and D3C Spider

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.
