D4 Rainbow Flange Screw

OEM - Original Equipment Manufacturer
Brand: Rainbow®
Manufacturer: Rexair
Item Number: H542
Availability: In Stock
Condition: New
Online Price: $0.20 USD

Add to Cart

Standard R747 flange screw for the model D4C SE (Special Edition) and D4C Rainbow. Most of the time, this screw will need to be replaced as the glue that gets stuck down in the slots and rust over time degrades this part.

If you currently only have four screws, please keep in mind that all new R747 flanges have eight screw holes so you will need to order eight of these screws for proper installation.

D4 and D3 Bearing Boot

OEM - Original Equipment Manufacturer
Brand: Rainbow®
Manufacturer: Rexair
Item Number: R1987
Availability: In Stock
Condition: New
Online Price: $1.30 USD

Add to Cart

Bearing boot for the D4C SE (Special Edition), D4C, D3C, and D3A Rainbow vacuum.

The second image shows the old version (left) that has a smaller hole and can only be used on the D3A or D3C motor. If you have a mix of parts, do not use the old design on a D4C model Rainbow.

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

It is a good idea to replace the bearing retainer shield due to rust and low price of item.

Factory OEM original motor gasket for the model D4C SE (Special Edition) and D4C Rainbow. This gasket can get hard and crack overtime reducing the systems performance. During a repair, replace this item if you feel your existing gasket is compromised or damaged.

We recommend GOOP adhesive to seal this gasket to the main unit. Latch the water pan on when finished for about 30 minutes to allow the glue to dry.

Rainbow Version Two D4 and D3C Spider

OEM - Original Equipment Manufacturer
Brand: Rainbow®
Manufacturer: Rexair
Item Number: R4101
Availability: In Stock
Condition: New
Regular: $19.92 USD
Online: $12.26 USD

Add to Cart

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.

Condition: New
Regular: $14.98 USD
Online: $9.22 USD

Add to Cart

This genuine factory OEM part fits the D4 SE (Special Edition), D4, D3, D2, and D model Rainbows.

For a small period of time, there was a four screw hole version (stamped R-6425) but now the eight screw holes are standard and will fit all models listed.

Original version (image two) was not coated and did not stand up to the water as well as the new version with the black coating.
