5/16 STEEL CHECK BALL (Toyota TY0360-08009)

A worn check ball can allow fluid to bypass, reducing system pressure and causing erratic operation. This aftermarket replacement part references Toyota as the OE maker and carries the cross-reference number TY0360-08009. The check ball is a small spherical component that seats in a valve body to permit one-way flow. Its plain mechanical function is to block reverse fluid movement when pressure shifts. If the ball becomes pitted or out-of-round, it may fail to seal, leading to internal leakage and loss of function. In a typical usage context, this part is replaced during valve overhaul when leakage is detected. Verify the serial number or application, then call (562) 693-7748.
