Trilogy actuator

[Tom]

Need a little advise. Sent the Trilogy out for a rebuild and was told the actuator is shot. IS there anything I can use to replace the old actuator since it is a Trilogy specific part.THANKS

You talking about the boost bypass valve? Isn't that the same as a normal eaton? The Trilogy blower is a Magnuson design and Magnuson based the "MP112" on the Eaton M112, it shouldn't be some super proprietary Trilogy part.

agree. stiegemeier had a whole box of them as i recall.

I am almost positive that it is a different part in how it mounts and the proper orientation than a typical Eaton.

I know I went thru great lengths trying to find one made for high lift cams at one time and ultimately gutted mine and trimmed the internal spring to delay its closing. Hopefully this is not what I am remembering but I think I was trying to get a new replacement before I did surgery on mine.

I can say it was quite easy to open and reseal with silicone. Unless your diaphragm has an actual tear in it (and you would have known as the blower would have been screaming at you even at idle or you would have zero boost or sound for that matter) I can’t see why you couldn’t open it up to check the diaphragm and spring, clean, and reseal it easily.

Your rebuilder could very well just be looking to cover his work with new parts? I’m sure they go bad like anything else but I’ve yet to witness one personally.

There should be a part number on the bracket and JonBondPerformance lists quite a few.

I’d call Jerry Barnes if you hit a dead end.

There was a guy in So. FL that sold Magnuson parts and I cannot find his info for the life of me. I will PM ya if I get lucky

It is not the same as an Eaton.

Guittard22 had a Trilogy unit he talked about selling, I think it needed a rotor.. maybe use as parts blower

I had to buy one and swap the canister to my bracket.
