Titan 185-981 Roll Plated Pin for Hydra Pro IV and Compatible Systems
Titan 185-981 is an OEM roll pin engineered for use in the fluid pump assemblies of compatible Titan spray systems. According to the official Titan Hydra Pro IV service manual, this roll pin is used to secure the connecting rod within the 185-551 Fluid Pump Assembly, and is removed and reinserted during pump disassembly and reassembly. This precision component ensures proper alignment and retention of the connecting rod, maintaining reliable power transmission from the motor to the fluid pump. A worn, missing, or damaged roll pin can cause the connecting rod to shift or separate, leading to pump misalignment and loss of drive efficiency.
