Spring cup 320/07578 is a genuine JCB part for the JCB Dieselmax 444 engine.

The spring cup carries the end of a spring and spreads its force evenly onto the part. A worn or cracked cup lets the spring shift and the assembly work unevenly. The cup size is set by the spring and application. The cup is steel or plastic and is replaced if the face in contact with the spring is worn. It can also set the height needed for correct spring preload. Its size is defined by the part number and it is compared with the old cup. Keep the cup face clean and free of grit.
