HPI Baja 5b family Steel Clutch Bell 5mm Bore SBJ613 by GPM  [SBJ613]

Heavy-duty clutch bell for Baja use

The SBJ613 is a steel clutch bell with a 5mm internal bore designed for HPI Baja 5b, 5b Ss and 5T vehicles referenced in the title. It arrives as one unit and includes the necessary screw and lock nut to fasten the bell to appropriate pinion configurations.

As part of the drive train, the bell transfers motor torque into the clutch assembly. Steel offers improved resistance to wear when used with matching pinions. Always verify the 5mm bore matches your motor or pinion shaft prior to fitting.

Fitting guidance: remove the old bell from the clutch, slide SBJ613 onto the shaft or pinion so the 5mm bore seats correctly, fit the provided screw and lock nut, and snug to a modest torque to prevent loosening from vibration. Check axial runout and mesh clearance after installation for trouble-free operation.

Use the SBJ613 when replacing worn steel bells or when synchronising gearing on HPI Baja 5b series vehicles, keeping alignment and secure fastening as priorities for dependable drivetrain behaviour.
