The Spanner Wrench supports removal and installation actions by applying rotational input to threaded cylinder head interfaces. Through direct engagement with matching features, the tool enables the transfer of turning force into linear movement along threads, supporting the separation or seating of the cylinder head during service activities. This rotational control helps manage resistance changes as the head moves along its threaded path. It supports repeated turning cycles, allowing repositioning and continued rotation until the required movement of the cylinder head is completed within the lift cylinder service process.Attributes:• Enables rotation of threaded cylinder head interfaces.• Supports removal action through controlled turning.• Transfers hand input into rotational movement.Applications: The Spanner Wrench is used to remove and install intermediate cylinder heads in off-highway truck lift cylinders during service operations.
