• Common signs of failure: cracked or missing cap, spring won't stay seated, loose/uneven movement, squeaking or clicking noises

• Disconnect power to the appliance; shut off water supply if applicable
• Control spring tension carefully and wear cut-resistant gloves/eye protection
• Note the cap's orientation; seat the spring fully in the cap and bracket before reassembly
• Inspect related spring and linkage; replace any worn parts for best results

This cap spring is a small coil that supplies the return tension a cap or button needs to operate smoothly. Replace it if weakened, bent, or missing to restore proper feel and reliable engagement of the mechanism.

• Maintains spring tension under a cap/button to keep parts aligned
• Helps the cap return smoothly and prevents looseness or rattling
• Supports consistent engagement of the related control or latch
• Typical signs of fatigue: loose or wobbly cap, sticking action, poor return, or a spring that pops out

• Disconnect power and shut off water/gas supplies before servicing
• Note the spring's orientation and stack-up; take photos as you disassemble
• Use needle-nose pliers and control the spring so it doesn't eject
• Seat components fully and test operation before final reassembly

This genuine replacement gear is a drivetrain component that transfers motor rotation to a mating mechanism inside your appliance. Replacing a worn or stripped gear restores smooth, reliable motion and helps prevent damage to adjacent parts.

• Meshes with adjacent gear(s) or a shaft to drive an internal mechanism

• Includes 1 gray speed control lever

• Unplug the mixer before servicing
• Remove the end cover/trim band to access the speed control mechanism
• Note the spring/link orientation and transfer any original hardware as needed
• After reassembly, verify all speed positions; adjust the control plate per the service instructions if speeds do not align

Color: White

This governor drive stud links the motor armature to the mechanical speed governor, allowing the governor to rotate and regulate motor speed. Replacing a worn or missing stud helps restore smooth, consistent speed control in your stand mixer. What it does

• Transfers rotation from the armature shaft to the governor assembly for accurate speed regulation
• Helps the mixer maintain set speed under varying load
• Replaces a damaged, sheared, or missing drive pin
