BAL 21100005 Powered C-Jack Exploded Parts Diagram & 12V Motor Guide

Identify individual service parts in the BAL Powered C-Jack 21100005 cross-frame stabilizer system. This guide follows BAL's official numbered parts diagram and parts list, distinguishes the full dual-motor assembly from replacement pieces, and links directly to matching components listed at NewRVParts.

Model identification matters: BAL 21100005 uses two independently controlled 12-volt motors and 25-inch C-Jack legs. BAL explicitly cautions that a manual C-Jack is not a direct replacement for a powered C-Jack. Do not assume another BAL model's components interchange based solely on appearance.

Select a motor, coupler or complete assembly

231000 motor: BAL identifies callout 10 as its 12V motor-and-gearbox assembly; the complete jack has two motors. Match the original motor label and mounting before ordering.

20300030 coupler: callout 9 connects the matching motor drive and jack drive rod. Inspect original shaft geometry and coupler type; do not assume universal fitment.

21100005 complete assembly: appropriate when replacing the entire matching powered cross-frame system, subject to trailer frame dimensions, mounting and wiring requirements.

C-Jack foot pads: BAL identifies 23100 as a single replacement pad (factory callout 6; two pads in a complete 21100005 system). BAL also specifies 23200 as a two-pad bolt-on kit for manual and powered C-Jacks, including 21100005. The 23200 kit contains two 5½-inch square pads with bolts. Confirm the mounting tabs and original pad arrangement before ordering.

Mounting, electrical and operation notes

  • Confirm the RV frame/sub-frame can support the stabilizer's intended loads and has a suitable unobstructed mounting surface. BAL's installation manual specifies 66.5–70.5 in frame widths and a minimum 8-in unobstructed mounting area per side; verify both dimensions and follow the factory mounting and wiring steps.
  • Two 12V switches allow individual leg control. The original parts list identifies two 15-amp automatic-reset breakers under 20300031.
  • These jacks are intended for fine leveling and stabilizing a parked travel trailer or fifth wheel, not for raising tires off the ground or supporting wheel-service work.
  • Never use a cordless drill to override a powered jack's gearbox; BAL warns this can damage the unit.
  • Retract both stabilizers fully before moving the trailer.
