Precision 56T steel spur for Baja 5b

This hardened 56-tooth steel spur is a direct replacement part for RC Baja 5b, 5b Ss and 5T models requiring a 56T spur. Supplied as 1 pcs, it is intended to be paired with the specified GPM SBJ018T pinion to achieve accurate gear mesh and alignment.

Engineered for durability in off-road drivetrain assemblies, the spur provides consistent tooth contact under load. During installation, verify backlash and mesh with the motor pinion, torque retaining hardware to the chassis guidance, and confirm the drivetrain rotates freely before operation.

Specifications

  • Item: Steel spur gear 56T
  • Material: Steel
  • Model Number: SBJ056T
  • Compatibility: Baja 5b/5b Ss/5T
  • Quantity: 1 pcs
  • Required Pinion: GPM SBJ018T

Select this hardened steel 56T spur when durability and steady wear characteristics are required for demanding scale off-road drivetrain applications.

What tolerances should I check when fitting SBJ056T?

Check bore concentricity, tooth profile engagement and axial clearance. Proper mesh with the GPM SBJ018T pinion is essential to avoid edge loading and premature wear.

Do steel spurs require special break-in?

A short run-in at low load to observe mesh and noise is recommended. Confirm torque specs and recheck backlash after the initial running period.

How does SBJ056T affect drivetrain longevity?

Hardened steel resists wear better than softer materials, helping maintain consistent gear geometry under stress, but correct mesh and ongoing maintenance remain decisive factors for service life.

What inspection regime is recommended for competition use?

Inspect teeth for deformation, check for burrs at the bore and verify retention hardware after each event. Replace the spur if any tooth damage or uneven wear is detected.
