Title: converting a A.C. Alt over to a non A.C. alt
Post by: 2xEaglewagons on February 11, 2017, 12:01:52 PM
Hello
Would like to remove the A.C. from car.
Compressor is heavy,bearing is going bad,and multiple belts/idler pulleys wake up my neighbors early A.M.
I have never used the A.C.,,it was -14 Celsius the other day in Canada!
May also add 5 H.P. to car with 2 belts instead of 3.
I just wanna make sure I am not missing anything.
From what i see we need a dual belt water pump pulley(A.C. is single).
And brackets and brace to relocate Alt up higher.
Thanks for any hints or help!!

hi, yes the non AC cars had different alternator bracket. Kind of hard to find, since most Eagles (here anyway) were sold with AC. Up there, they still may be some in salvage yards. An option is to just replace the AC clutch and leave it alone, as there is really no HP loss if the AC is not used. Another option is to look for the 1984+ compressor, smaller, lighter and less HP loss, and bolts right up to the existing bracket and uses same belt. It's a Sanden 508. Even a used one will work as long as the clutch bearing is good. Came on Jeeps as well. good luck, gz

Well another option is to put another alternator there i did that to use the car to have a portable welder. The 12 volt unregulated altenator is quite powerful. The amps stay whatever alt you put in but the volts unregulated goes way up with rpm. It makes a stick welder scream. They say you cannot weld on your own car however. Just somthing i have done. I had to still fab up a bracket so idk.
