NOTES: Series 6921A generator sets, with wide generator bearings, supersede Series 6921 gene-
rator sets having standard generator bearings. Series 6922A generator sets are similar to
corresponding Series 6921A units, but without canopy insulation. Series 6922B generator
sets are identical to Series 6922A generator sets. The "B" designation is for administrative
purposes.
Units 6921A-1 thru 6921A-6, along with 6922-1 and 6922-2, use Hobart Voltage Regulator
Part No. 430391C. Units 6921A-7 thru 6921A-11, along with 6922-3 and 6922-4, use Hobart
Voltage Regulator Part No. 489812. Refer to manuals TM-759 and OM-2020, respectively, in
Chapter 6 for detailed information on these regulators.
