Rowe's OBA-2 Bill Transport
Repair & Maintenance (Part 11
Rowe's OBA-2 Bill Transport can be found in most of
Rowe's jukeboxes, old and new. Rowe's CD-100series
jukeboxes all have the OBA-2 Bill Transport in them.
Everything from Video Poker Terminals to Vending
Machines use the Rowe OBA-2 Bill Transports.
Set the BTinfront of you with the bill input away from
you . As you disassemble the BT, arrange the screws
and shafts in the order you take them off. This way if
you get lost, you can retrace your steps. Follow these
steps as you ref er to Figures 1 & 2:
In light of their popularity, I decided to give you some
information on maintaining and repairing the OBA-2
Bill Transport. This issue will deal with changing the
Upper Belts, and cleaning of the optics. Part II (next
issue) will deal with troubleshooting and repair.
a) Remove Pivot Screws with Spacers (Figure 1, step
1) and remove Top Cover.
b) Back out Casting Screws until Wire Spring can be
removed (Figure 2, steps 2 & 3) .
c) Remove Nut (11/32"). then Central Roller Spring.

The first thing we'll talk about is
changing the OBA-2 Bill Transporfs (BT
from now on) Upper Belts. This is
probably the most common problem.
Leaming to change your own belts will
save you down time and money. The
belts run around $2.50 or $3.00 each,
maybe more with some sources.

Replacing the belts yourself will also
give you a better understanding of how
the BT works and how to disassemble
the BT for other repairs. The BT may
look rather confusing, but after you do
a couple, disassembling and cleaning
should take about 15 minutes . This can
be done on location if you have a place
to work (a cocktail table will do).
