Case Rub?

Jrock909 · 02-07-2010, 06:15 AM

Guys is it easy to get case rubbing with the rotors on the eaton if the sequence or torque specs are a little bit off when installing supercharger back onto the midplate....?

Unless you got crazy with them it shouldn't be a problem. Can't you find a torque wrench to borrow though?

I got a torque wrench, just wondering if it was possible to get case rub being slightly off a little bit....

Use that torque wrench and you'll be perfectly fine.

Rotor end to Rotor plate typically is .004" and the opposite side is around .008" to .012". Then the diameter of the Rotors as compared to the Rotor Bore's is .004" per side. So the rotors are .008" smaller than their respective Bore's.

A lot of the Rubbing that's seen is actually debri's getting pinned in between the Rotors and the Rotor bore's. All it does is scratch and then disappears into the engine unfortunately. It's not Rotor to Case rub. Rotor to case rub does happen quite a bit but I think it gets blown out or proportion. If it's just lines you or anyone else sees it's only debri's working its way through. Rotor to Case rub is easily seen as "damage or gauling on the rotor tips or inside the case". Not just a .010" wide scratch.

In other words OP you should be perfectly fine and if you have any questions pm me or give me a call during the day 502-222-0488. I might not be an authorized Eaton remanufacturer but if you give me a solid block of Aluminum I can build one of these from scratch.

Well except for the Rotors lol.

Sorry I went a little deep.

No posi you're fine man, you can't never have a enough knowledge and that little bit extra man is always a bonus, especially learning this info from an experienced guy as yourself that sounds like.... I'm going to probably play this for time to see if the sound just goes away, because I did what you said and retorqued the case to the midplate last night and took my time and still getting the cold noise sound from the supercharger, I spun the eaton without the belt on it and it bolted to the midplate last night and it felt smooth no play anywhere whatsoever...
