Titan 0532215 Upper Bushing

Part number 0532215 is an Upper Bushing, a precision-machined component engineered for the Titan Impact 400 and Impact 340 airless sprayer fluid sections. This bushing threads directly into the top of the pump housing and serves two critical functions: it secures and compresses the upper packing into its proper seated position, and it provides a precision bearing surface that guides the piston rod during the entire pressure and suction stroke. The upper bushing is a fundamental component of the Packing Kit P/N 0532911, which contains all wearable seals required for complete fluid section overhaul.

During fluid section service, the upper bushing must be removed using an adjustable wrench to access the worn upper and lower packings. During reassembly, the new upper packing is first installed into the pump housing with its raised lip facing downward. The upper bushing is then threaded into the housing and tightened to a specific torque of 300-360 in-lbs. This controlled compression drives the upper packing into its precise operating position, creating the high-pressure seal essential for pump performance. The bushing also receives several drops of separating oil during final assembly to lubricate the piston interface and extend seal life.

The upper bushing is manufactured from durable materials with precision-cut threads and a smooth internal bore. Failure modes include thread damage from over-torquing or cross-threading, hex drive wear from repeated service, and corrosion from chemical exposure. A damaged or worn upper bushing compromises upper packing retention, allows piston misalignment, and can lead to premature seal failure and external leakage. Replacement with genuine 0532215 upper bushing during fluid section overhaul restores proper packing compression and ensures reliable pump operation.
