The Chelsea 680XQAHX-V5RF (also referenced as 680XQAHXV5RF) is a 680 Series Power Take-Off built around an 8-bolt mounting configuration for manual transmission applications. The 680 Series uses a cast iron housing with tapered cone bearings on the output shaft and tapered bearings on the input shaft, giving it higher load-bearing capability than needle-bearing designs. It covers Eaton Fuller transmissions and includes a deep-mount housing option suited to Mack applications. The series supports four internal speed ratios and ten shift options, including wire/cable and mechanical shift. Output options span SAE A, SAE B, and SAE C pump flanges, a 1410 companion flange, and multiple spline configurations. Call us to confirm the exact output configuration and ratio for your application.
