A Similar Unit in 110-115 Amps, is the 13242. This Unit Looks Just Like the 14944 and the 13247, Except That the Bottom Mounting Holes are 10mm (Instead of 8mm), and it Uses a Single V-Groove Pulley That is Set out From the Fan an Inch or So (Pulleys Should be Exchangeable Between Units). The Clock Position of the 14972 is Slightly Different Than the Other Two, But This May Not Be a Problem if Trying to Interchange the Above. The Late 14972 (OEM No. 0-120-469-953) Has a "W" Terminal. We Call This Number a 14988. See 14988 For More Details.
