I got a 20+ year old Warn 8274, and needed some info about oiling and replacement clutch/free spool install...they have hancged the part, it is no longer a round palm held knob, but they have the same unit, but with a T handle (much easier to use) I emailed Warn, got full and prompt help and even PDF diagrams from Michael McKewen, Technical advisor.....

Good on 'em!
