These superchargers are in high demand. Not necessarily easy to come by. With this in mind, our Shop Foreman designed this kit to be the quickest way to put a supercharger you already own back into service, with much of the work performed by you or your mechanic, to help with cost and turnaround time savings. This kit is especially great for automotive repair shops where the mechanic can keep the cost and turnaround time down by completing the less difficult work in his repair facility.
This item is a do-it-yourself complete rebuild kit with a pre-built and timed rotor assembly. It is ready to install into your supercharger housing by you or your mechanic. It comes with a parts kit to rebuild the Eaton M90 Gen3 Snout Nose Drive. Also included is a pair of rotor shaft needle bearings that are quality controlled checked and ready for installation by you or your mechanic into the supercharger housing.
Or...
To have a supercharger completely serviced by us, you send your core in for the rebuild. We have a Complete Rebuild Service which you can send your supercharger in to have performed. In this way you avoid a large core charge I would have to hold if I sent you a completely rebuilt and ready to install supercharger to you before a core supercharger is received by us.
The Complete Rebuild Service for the Eaton M90 Gen3 supercharger is as follows:
Complete Rebuild Service Eaton M90 Gen3 with durable, Thermal Barrier Rotor Coating
Our do it yourself Complete Rebuild kit saves you several hundred Dollars, or gives a fantastic potential profit margin for an automotive repair shop.
This item is a rotor assembly that has been newly re-manufactured with the rotors newly re-coated and precision-timed. It includes a Supercharger Complete Rebuild Parts Kit that includes all the parts needed for the complete service of the supercharger.
Buy this item because the rotor assembly is already professionally re-manufactured for you. Our rotor assembly bearings are retained by an Aluminum plate designed and CNC manufactured specifically for this application.. This is the only method of bearing retention we trust for our supercharger rebuilding services. Now, you can use this professional, reliable method to completely rebuild your Eaton supercharger yourself, saving you time and money. NO ALUMINUM WELDING REQUIRED. A U.S. Patent has been applied for to protect this bearing retention process from unauthorized use by anyone but the designer of the process or his legal beneficiaries, Patent Pending.
Our rotor assembly is built to the exact same specifications we use when we rebuild a supercharger at Embree Specialty Machine. To assist you in your assembly work, the tolerances are listed in this item description. The bearings and seals used are upgraded from the original part specifications and most importantly, the rotor seals are now a Double-lip Viton.
We completely disassemble the rotor assembly plate including removing the old seals and bearings. The bearing plate is carefully measured and paired with a newly recoated pair of rotors. The rotor coating is our durable thermal barrier, interference-fit coating, similar to Piston Skirt coating in durability and environment parameters. Our coating is durable in harsh environments found in configurations using nitrous injection systems, methanol or water injection. Then the rotor assembly plate is CNC machined to accomplish correct rotor timing and front rotor-to-bearing plate clearance, set at 0.006" to 0.009" and the mesh is split +/- 0.001" for optimum supercharger operation. Both rotor seals and rotor ball bearing have been replaced.
What does this item include?
This item includes the same high quality parts we use in our rebuild services. This kit contains an re-manufactured rotor assembly. This item is Quality Control checked. As an informed DIY Do-It-Yourself person, you are purchasing this component to complete the rebuild service yourself.

FREQUENTLY ASKED QUESTIONS:
If I have a non-supercharged car, can I buy this item and get a complete supercharger head unit with the engine fit kit including everything that is needed to install a supercharger on my vehicle?
No, you will need to provide for exchange, your rotor assembly or pay the core charge. This is not a complete supercharger. Instead this is a kit that contains the components to rebuild a supercharger you already own.
Who and what is this kit designed for?
For the Shop Technician or DIY Do-It-Yourself person, this kit includes the Re-manufactured Rotor Assembly. Get the same Premium Quality bearings and seals used in our Complete Rebuild Service. This item has been designed by our Shop Foreman, based on years of successfully servicing Eaton superchargers to give you the Best Chance at Success™ when performing the supercharger rebuild service yourself.
If you decide at any point to have a professional perform this service, send it in. The rotor assembly is correct when it leaves the shop. Damage that occurs after the point where it is packaged for shipment from us, is completely on the mechanical person performing the rebuild service, whether you or your mechanic. No refunds will be given however, if you run into issues, contact us first because we can help.
What can be done to confirm this is the right item for my application?
Send us a message with some cellular phone photos of the supercharger to be serviced.
This is an important first step. The Shop Foreman will require these pictures to identify the supercharger and to help us make sure proper components are sent. There are several variations that must be considered to make sure the drive gear is on the correct side of the rotor assembly and the correct ball bearings are provided. For a list of most compatible vehicles see the compatibility chart.
We are happy to help you make sure you order the right part for the job. If you have ANY DOUBTS about this being the one your application needs, please email us before you purchase this item. Include a cellular phone photo of the one you are replacing, for the Shop Foreman to look at. Also, include the year, make, model and trim level to assist in the identification of the vehicle application.
It is not always easy to be sure what you have because there are so many variations to the Eaton superchargers. With this in mind we want you to know that if the rotor assembly that arrives does not match the one you need to replace, contact us immediately. Do not panic and remember we have offered this because we want to help you get the right parts. We want you to have the right one and will work with you to exchange it when an honest mistake is made. Please help us by making your best effort to be sure which rotor assembly you need before you place your order. It is okay to tell us in your order email that you are not sure what you need. It can really help us to help you if you would email us a photo, and for this cell phone photos work great. We can prevent delays and frustration by looking at your snapshots for 5 minutes instead of all the extra work to exchange the part. Let us help you up front if you aren't 100% sure you know what you have and what you need.
Is this the right kit for a supercharger with a short nose drive?
No. Some of the M90 superchargers come with short nose drives that need a single double-row ball bearing instead of two single-row ball bearings. If you have one or suspect you have one, you should send us a photo of your short nose drive supercharger because we must know in order to provide the appropriate nose drive ball bearings. We have the appropriate parts and you will want to confirm this with your order so that we can include the correct parts in your kit.
What is the difference between the Eaton M90 and M112 superchargers?
This eBay item is for an Eaton M90 which shares the same bearing plate as an M112 but the M112 rotors are longer. The M112 kits are available through our eBay Store, too. Message us with questions and we can help you determine what item is right for you.
How can the Eaton supercharger model be determined?
With the Gen 1, 2 & 3 Eaton superchargers, this is a simple matter to determine because holding the nose drive on the:
Eaton M45 Gen 3 has 8 bolts
Eaton M62 Gen 3 has 8 bolts
Eaton M90 Gen 3 has 9 bolts
If the supercharger bearing plate you are working on looks way different than this, then just email us some phone pictures and ask our Shop Foreman to assist you in determining the supercharger type you have and what kit you need.
THIS ITEM IS FOR: Eaton M90 Gen3
THIS ITEM IS NOT FOR:
Eaton M45 Gen3
Eaton M45 Gen3 with short nose drive
Eaton M45 Gen4
Eaton M45 Gen5
Eaton M62 Gen3
Eaton M62 Gen4
Eaton M62 Gen5
Eaton M90 Gen4
Eaton M90 Gen5
Eaton M112 Gen4
Eaton M112 Gen5
Eaton M122
Eaton TVS 4-lobe
This kit is NOT for these supercharger model/generations because they use a different rotor assembly bearing plates. Please contact us to get more details about a supercharger rebuild kit for these or other Eaton Models that are not listed here.
What are the specifications for the Rotor Coating?
Superior, our Rotor Coating is very consistent because it is thickness checked during quality control inspection to ensure even application. Not all rotor coating available in the market is precision checked like ours. We check them so carefully after coating because the rotor assembly will work best and most quietly with proper thickness of rotor coating. You can see that the bearing plate is precision CNC machined to set the ideal tolerances, giving you optimum performance.
What does this supercharger rebuild kit process include?
You, the buyer will have the parts that you need to replace the rear rotor needle bearings, rebuild the nose drive snout and install the rotor assembly yourself.
Technical support from the Shop Foreman is available during normal business hours.
What are some important process points that can help with the rebuild process?
The inside race of the front nose drive ball bearing must be supported when installing the shaft. This means the shaft must be installed before the front nose drive seal is installed because the front nose drive seal will cover the inner race of the front nose drive bearing when the seal is installed. If you do not support the inner race, it will result in installation damage to the ball bearing. A clicking noise in the bearing after installation is a symptom of this.
Never use ball bearings with dust covers because in this application they are used in an oil bath.
After the rotor pack is installed, you need to check rear rotor clearance.
Should a contact phone number be provided by the buyer when the item is ordered or purchased?
Providing a phone number is always helpful and leads to better service because we can contact you if there are any questions about your order. Of course we never have time to spam and never share information.
What will the supercharger rebuild process include when using this kit?
You, the buyer will have the parts that you need to replace the rear rotor needle bearings, rebuild the nose drive snout and install the rotor assembly yourself. After the rotor pack is installed, you need to check rear rotor clearance.
We recommend using Permatex Anaerobic Gasket Maker (PX#51817 NET .20 FL OZ or PX#51813 NET 1.69 FL OZ) which is designed for Aluminum flanges, available at some auto parts stores. Do not get any sealer or any debris in the rotors during installation. Do not use too much sealer or it will squeeze out into the rotors which will damage the supercharger. Completely clean any old sealer off the surfaces you are connecting the supercharger to because leaving the old sealer on the flanges will distort the supercharger housing when bolted together and cause failure. Follow the instructions on the package of the sealer for best results.
What is the tolerance goal for my assembly to work properly?
You will want a minimum gap of 0.006" to 0.010". The gap can be greater than 0.010" however this wide of a gap will allow for air charge leakage. The smaller the gap between the rear housing and the back rotor faces, the tighter the supercharger seal. The rotors should never touch each other or the housing internal bores, anywhere at all.
What Warranty Coverage is included with my purchase?
Our One-Year Warranty and our long-term eBay reputation will be your peace of mind.
Core Charge Details (YOU HAVE A CHOICE!):
CHOICE (A):
Purchase this item which includes a core charge. The new item will go out as soon as possible and before your core is received. You can keep your core if you prefer. We hope to encourage you to return the core by including a core charge. If you would like to send it in for a refund of the core charge, return ship it back to us within 15 days of receipt of the item. The cost of return shipping is always the buyer's responsibility so ship as cheaply as possible. The box our kit is sent to you in is built tough enough that you can use it to return your used rotor assembly core. So there is no need for you to round up a box and packing material. We want this to be easy for you. After you ship it, email me a tracking number to help identify yours by alerting us to its return. The Shop Foreman's inspection check in of the returned core will determine damage that will affect the core refund if it makes the core parts unusable for the next customer. See choice (B) to understand your options.
CHOICE (B):
To avoid the core charge, you purchase this item without adding a core charge and would then ship your core immediately. Our item will ship after the used rotor assembly is received. In this way, we can help you avoid the core charge while continuing to keep costs low for everyone.
