G 33885 BOOM ROD

The G 33885 Boom Rod (1 3/4" × 48") is a critical hydraulic component used in the backhoe boom cylinder assembly of Case 580 backhoe loaders.
This cylinder rod transfers hydraulic force generated inside the cylinder into mechanical movement, enabling precise lifting, lowering, and positioning of the boom during digging and excavation operations.

Manufactured to withstand high hydraulic pressure, heavy axial loads, and continuous reciprocating motion, this boom rod plays an essential role in maintaining smooth boom operation, structural stability, and overall machine productivity under demanding working conditions.
