GENERAL INFORMATION
The NV 021 PTO adapter provides power take-off
capability for 2-wheel drive BR models with an auto­
matic transmission. The adapter is available as an
option on 2500 and 3500 models.
The NV 021 adapter is similar in appearance and
mounting to a small transfer case (Fig. 1). A 4-wheel
drive automatic transmission is used to simplify
adapter mounting. The adapter has mounting studs
in the front case for attachment to the overdrive unit
gear case.
