Product Description

The Eaton M45 Supercharger is normally rated for 100,000 miles, but many of these units can vary greatly in mileage. The most common issue we see is the rear gear assembly runs dry because of a worn out seal. When the rear seal fails, the gear lubrication leaks out of the supercharger, leaving the rear PTO gears dry, causing the large pulley to wear a grove in the smaller pulley. When this happens the water pump stops spinning at some point and causes the engine to overheat. 

All Detroit Tuned Superchargers come with new:

  • Nose Cone Bearings
  • Nose Cone Seal
  • PTO Gears
  • PTO Bearings
  • Rear Bearing & Seal Retainer System 
  • Heavy Duty Extreme use Seals that Exceed OEM Quality
  • High Temp Supercharger Lubrication Oil

About the rebuild: These are rebuilt locally for us, and only for us per our spec, with new parts that have been designed by us. We are now on the 3rd and final rear gear design that has a new and better tooth design that is not only quite but has less play in them, and we also hardened them for a longer life. We also redesigned the seal capture system for the rear bearing so that the fluid can't leak out again. What we have learned from all the failed units, is that we have seen the rear gears failed due to lack of oil. The oil leaked out the back due to a seal failure and caused the bearing to move around in the back plate where it meets the water pump. This was all due to how Eaton rolled the lip over to capture the bearing for the rear gear. To top it all off, we added new fluid to both the front and the rear that is far superior to the GM fluid it came with. This makes a complete ready to bolt on unit that requires nothing for the customer to do other than bolt it on and drive away!

Lets make it faster!  DT Superchargers can come with a stock size pulley installed read to go, but for a few dollars more you can have a 15% or even a 17% pulley installed. If you're adding a pulley, don't forget a new shorter belt and a set of colder plugs to round out the performance needs for your MINI! If you already have an under drive pulley on your current supercharger, take it off before shipping the core back. Select the "No Pulley" option and the supercharger will come ready for you to install your under drive pulley! Also think about a new Supercharger Intake Gasket, Water Pump, or Water Pump O-Ring (fits on the block connection), while you’re at it!

Core Return Form

Note: These DT superchargers carry a two year-unlimited mileage warranty from the date of purchase and come ready to bolt on. There is a $500.00 core charge. Old units must be returned within 3 weeks and must be in rebuildable condition. Each DT Supercharger is different in how it's finished look will come out, the rotor coating on early units may not be always perfect, but all work up to spec.
