HPI Baja Alloy Clutch Bell BJ613 for Maintenance by GPM  [BJ613]

Alloy clutch bell suited to HPI Baja

The BJ613 alloy clutch bell is an aftermarket direct replacement for HPI Baja RTR vehicles, offering reliable engagement for off-road 1/5 scale setups. It is aimed at hobbyists who carry out routine clutch servicing and tuning.

Made from aluminum alloy as stated in the title, this bell can take the place of worn steel or cast parts to help keep clutch shoes contacting cleanly while limiting heat transfer to nearby bearings and gears. The item bundle includes the mounting screw and lock nut listed in the product name to fasten the bell to the clutch hub.

Fitting is straightforward for anyone used to clutch work: remove the stock bell, examine clutch shoes and bearings, mount the BJ613 and secure it with the supplied screw and lock nut. Confirm concentric alignment and free spin prior to reassembly to reduce risk of abnormal wear on the spur or pinion.

As a tuning component, an alloy bell will slightly affect heat dissipation and wear patterns; treat it as one factor in a complete clutch tune with springs, shoes and bearings. Routine inspection and appropriate lubrication will extend service life.

For those maintaining HPI Baja kits, the BJ613 alloy bell is a dependable replacement that supports consistent clutch performance when used alongside regular checks.
