Piston ring for Grove RT 522

The piston ring, identified by part number 9904110465, is a component installed within the piston grooves of the engine. It functions to seal the combustion chamber to maintain compression, scrape excess oil from the cylinder walls to manage lubricant consumption, and facilitate the transfer of heat from the piston to the cylinder walls for dissipation.

This part is compatible with Grove RT 522 and TR522 crane models. It is engineered to meet the specific requirements of the engines found in these rough-terrain crane units, ensuring that the engine maintains the necessary power output for lifting and travel operations while keeping oil and fuel consumption within design parameters.

Piston rings are used in internal combustion engines to create a seal between the piston and the cylinder wall. Compression rings are typically positioned at the top to contain combustion gases, while oil control rings are positioned lower to regulate the lubrication film on the cylinder liner. Proper fitment and sealing are necessary to prevent power loss, excessive oil burning, and premature wear of the cylinder bore.
