Block bolt 320/00917 is a genuine JCB part for the JCB Dieselmax 444 engine. The card also lists 320/02006, 320/02038.

The bolt holds a critical engine joint at a set preload, which is achieved by torque and angle. A stretched, rusted or thread-damaged bolt cannot carry the load and the joint may loosen. That is why bolts like this are best renewed after removal. Block bolts hold the engine's structural parts together; if they loosen, vibration and oil leaks follow.
