I purchased a used Warn 8274 I’m guessing is a 1980s vintage but not for certain. Winch was reported to be very well taken care of and I just picked up an ARB Commercial Bar to eventually install it on my 80 when the turtle build is brought back from the dead. Wanting to be sure about the winch and never having had one apart, are there parts I should inspect and how should it be serviced prior to install? Thanks in advance!
