The BAL EXACT-Slide G5.5 uses one motor on each side of the slide opening, operated by an electronic controller. The manufacturer changed motor sprocket design during 2022. These original motor numbers identify the installed versions, but BAL now lists 21900004 and 21900005 as obsolete and directs buyers to a model-specific replacement kit. Check the left/right position, motor label, tooth count and jamb mechanism number before seeking a replacement.
Original EXACT-Slide motor and controller illustrations
The manufacturer drawings identify left- and right-hand motor positions and distinguish the earlier 12-tooth sprockets from the later 10-tooth versions. For controller wiring and diagnostics, consult page 7 of BAL’s original EXACT-Slide service manual.

EXACT-Slide G5.5 motor identification
| Production reference | Left motor | Right motor | Sprocket |
|---|---|---|---|
| Through August 2022 | R25079 | R25078 | 12-tooth |
| From September 2022 | 21900005 | 21900004 | 10-tooth |
These are BAL's two documented original motor groups, not a list of currently orderable motors. BAL lists 21900004 and 21900005 as obsolete, with replacement kit 21700292 to be selected through an authorized dealer based on the RV brand and mechanism. Match the installed motor, sprocket and mechanism number before ordering; the 12-tooth and 10-tooth versions are not interchangeable by appearance alone.
BAL 10800194 current EXACT-Slide controller

Manufacturer-designated replacement for controller numbers 10800046, 10800090 and 10800160, with up to 35V high-voltage protection. Controller only; motors, cables and complete jambs are separate parts.
View the 10800194 controllerConfirm the controller part number on the installed unit and match the electrical connectors and actual EXACT-Slide version before ordering. A motor that does not operate may also be affected by cabling, mechanical binding or power supply faults; it is not automatically a failed controller.
Check the mechanism and wiring before replacement
BAL's EXACT-Slide G5.5 parts breakdown uses the mechanism label inside the jamb to identify the assembly. When service is required, compare that mechanism ID, the motor's left/right position, its sprocket tooth count and the installed controller.
