Rebuilding Procedures

When rebuilding the Eaton blower the unit is fully disassembled and all parts checked for wear, the case is thoroughly inspected for rotor rub.
Front drive is completely disassembled. The shaft is checked for straightness, all bearings and seals are replaced.
Front drive coupler is inspected for wear- Replaced if necessary.
Front rotor drive plate bearings- Measured for wear -Replace is necessary.
Rotors are then phased to corrected position and assembled.
Rotors are inspected for point wear and flaking, if your rotors are black they are Teflon coated, the wear on these are not accessible to flaking. If you have painted rotors that are gray and flaking we recommend stripping the rotors which eliminates any chance of further damage done from deteriorating finish.
The supercharger case is completely inspected for rotor rub. The rub is from contact of the rotor during rotation. This is always evident and more prominent on increased rotor speeds, (from smaller pulleys installed) these areas are marked, added clearance is machined to eliminate all rubbing.
Contact of rotors on a case will cause heat build up.
Rear case bearings are inspected and greased, replaced if needed.
All parts are high pressured washed at temp of 190 degrees for 30 minutes to ensure all components are absolutely clean, reassemble then takes place ensuring all bearing press and tolerances are triple checked and torque to factory specks.
Supercharger oil is added and all other lubricants are fully synthetic and Hi heat tolerant.
The outside of your supercharger case is inspected for paint imperfections and touched up if needed.
The by-pass valve is installed and collaborated for correct boost-charge and climb.
If your valve is broken we can most often fix these at a small cost, replacements are available.
At time of rebuilding we can install a optional size pulley for increased boost we have many sizes /colors available.
Porting your supercharger is an option that will increase the efficiency of your blower, adds boost in many cases, and Lowers inlet air temps also increases HP 15-60 depending on type and size of supercharger. (Blue printing is highly recommended on high performance applications this procedure is included in our porting process.)

Starting at $395.00 (Price varies depending on vehicle)
