🔌 Function

The ball seats against a machined surface to seal, index or locate within an assembly, functioning as a check element in a fluid passage or as a detent/locating ball in a mechanical linkage. Correct size and surface condition are essential for it to seat fully and operate reliably.

⚠️ Common Signs of Failure

• Visible flat spots, scoring or wear on the ball surface
• Pitting, rust or corrosion preventing a full seal against its seat
• Fluid or pressure leakage past the ball seat
• Sticking, notchy or lost detent action in the assembly it locates
• Ball dislodged or missing during disassembly, causing loss of function

🛠️ Service Notes

• Renew the ball whenever the valve or seat it works in is dismantled — a ball that has bedded into one seat will not seal in another
• Work spotlessly clean and handle it with clean hands or a magnet; grit carried in on a ball goes straight into the fuel or hydraulic circuit
• Inspect the seat for pitting, a wear ring or damage before fitting, because a marked seat will leak with any new ball
• Seat the ball with a soft drift and light taps only where the workshop manual for your engine actually calls for it to be seated, and never drive it in harder than the manual says
• Check the spring, guide or retainer that works with the ball is present, undamaged and fitted in the right order, then check the valve holds before returning the system to service
