TWL: 1963 Westerbeke genset

I'm trying to resuscitate my old Westerbeke genset (Perkins 4-107 with
an Onan generator section).  I'm replacing all the starting circuit
cables, as they've suffering a fair dose of voltage drop, and the ground
connection to the motor frame is literally smoking when I crank for 10
seconds or more.

I'm trying, though, to determine the cranking state of the motor
(whether the bearings are still bearing, and all that), and was
wondering if I can hand-crank it.  With the low voltage, the motor
barely turns when I throw the start switch and, of course, the question
is low voltage or seized bearings?

I'm asking because on my old sailing auxiliary Yanmar, there was a lever
on top that relieved the compression to allow for easy hand-cranking.  I
see no such equivalent on the Perkins.  Is there a way to hand-crank the
motor without compression resistance to determine the state of the
bearings?

Thanks.
