Repair of Hydraulic Bolt Tensioners

1.0 Scope: Pearl Harbor Naval Shipyard & Intermediate Maintenance Facility (PHNSY & IMF) has two (2) Hydratight Model No. 2Y07900 bolt tensioners that are currently non-functional and require repair to restore them to full operational condition in accordance with OEM specifications.

2.0 Requirements / Description of Work: The Contractor shall furnish all management, labor, materials, tools and equipment necessary to disassemble, inspect, repair and test each bolt tensioner.

2.1 Initial Assessment:

2.1.1 Conduct a pre-work visual inspection.

2.1.2 Identify and document all parts, noting signs of wear, pitting, scoring, corrosion, or mechanical damage.

2.2 Detailed Inspection:

2.2.1 Inspect both hydraulic stages, piston assemblies, and seals.

2.2.2 Check all threaded components and housings, for damage or distortion.

2.2.3 Evaluate hydraulic inlet/outlet fittings and quick-connects for leaks or fatigue.

2.2.4 Measure critical tolerances where applicable and compare to OEM specifications.

2.2.5 Provide a detailed inspection report including photos and findings in .pdf format to the Technical Point of Contact (TPOC) prior to starting repairs.

2.3 Repair / Refurbishment:

2.3.1 Clean all reusable components thoroughly using appropriate solvents and methods.

2.3.2 Replace all seals, O-rings, and worn components using genuine OEM parts or OEM-equivalent.

2.3.3 Refinish surfaces if required (light polishing or reconditioning only).

2.3.4 Reassemble the unit according to OEM torque and assembly guidelines.

2.3.5 The total combined cost of parts and labor to repair a single tensioner shall not exceed $30,000. The Contractor shall immediately notify the TPOC if the estimated repair cost for a single tensioner is projected to exceed $30,000.

Salvaged parts may be used in combination with OEM or OEM-equivalent parts as necessary.

2.4 Testing and Certification:

2.4.1 Pressure-test the tensioner to its rated working pressure to confirm sealing integrity.

2.4.2 Verify full piston stroke and correct operation across both hydraulic stages.

2.4.3 Check for leaks, abnormal noises, or hesitation in stroke action.

2.4.4 Certify the tool for safe operation and provide a final test and certification report in .pdf format to the technical point of contact via e-mail.
