PSS Shaft Seal Maintenance Kit 1 1/4" Shaft 1 3/4" Tube

The PSS Shaft Seal Maintenance Kit 1 1/4" Shaft 1 3/4" Tube (MPN: 07-114-134R) is a critical service component for marine and automotive drive systems that rely on PSS dynamic shaft seals. This maintenance kit addresses the inevitable wear and degradation that occurs on rubber bellows and seal components operating below the waterline or in harsh fluid environments. Regular inspection and timely replacement of PSS bellows prevents catastrophic leakage, bearing damage, and system failure—making this kit an essential part of proactive powertrain maintenance for boat owners, mechanics, and fleet operators.

PSS shaft seals use bellows geometry to accommodate shaft runout and movement while maintaining a watertight barrier around the 1 1/4" shaft diameter specified in this kit. The bellows naturally degrade from UV exposure, ozone attack, thermal cycling, and chemical contact with saltwater or diesel fuel—typically requiring replacement every six years even under ideal conditions. This maintenance kit includes all necessary replacement components and gaskets designed to restore factory seal integrity without requiring complete seal replacement or costly shaft modifications. The compact 4 x 4 x 8 inch package contains precision-engineered parts rated for the 1 3/4" tube bore dimension, ensuring proper fit and seal performance.

Mechanics and marine technicians rely on PSS maintenance kits to extend seal life and avoid emergency haul-outs or propulsion loss. This kit fits PSS seal installations where the shaft diameter measures exactly 1 1/4" and the tube housing is 1 3/4"—verify your seal's original documentation or measure both dimensions before ordering. Installation requires removing the shaft seal assembly, replacing the bellows and gasket components included in the kit, and reassembling with proper torque specifications. Regular bellows inspection every 12 months and replacement at the six-year service interval will keep your drive system leak-free and your bearing assemblies protected.
