The piston rod shall be ground to remove any cuts or scoring that may be present. The outside diameter of the rod shall then be built up by hard chrome plating to the final dimension and tolerances indica ted in the drawings. The hard chrome plating shall not be less than 0.005 inch thickness per side. The final rod surface shall have a roughness height of not more than 8 micro-inches rms. Any repair work to the rod not specified in this specification wi ll require a modification to the contract. If the Contractor has ground more than 0.010 inches per side without removing all imperfections, the Technical Repre sentative should be contacted to inspect and modify the contract, if necessary. 2.1.7 Pistons. The final outside diameter of the piston bushing shall be resized with the same tolerance ratio as specified on original prints to fit the inside diameter of the honed cylinder bore. Alternate designs or materials may be proposed by the contractor. All appropriate information should be forwarded to the Technical Representative for evaluation and approval. 2.1.8 O-Ring Seals. The O-ring seals shall be made of Buna-N or Viton and designed for 1000 psi service and the 1500 psi hydrostatic test. 2.1.9 Rod Wiper. Contractor shall propose modern wiper. All appropriate information should be forwarded to the Technical Representative for evaluation and appro val. 2.1.10 Piston Rings. Piston rings shall be sized accordingly to fit the honed cylinder bore. Contractor shall proposed the type of ring material. All appropriate information should be forwarded to the Technical Representative for evaluation and approval. 2.1.11 Piston Rod Seals. The type of seal shall be proposed by the Contractor. All appropriate information should be forwarded to the Technical Representative for evaluation and approval. 2.1.12 Rod Bushing. The existing bushing may be repaired and resized or a new bushing may be manufactured. The final inside diameter of the bushing shall conform to the same tolerance ratio as specified on original prints to fit the outside diameter of the rod. Alternate designs or materials may be pr oposed by the contractor. All appropriate information should be forwarded to the Technical Representative for evaluation and approval. 2.1.13 Trunnions (cylinder bracket). The cylinder No. 2 Trunnion has cracked welds at the trunnion/cylinder interface. These welds shall be gouged and repaired. 2.1.14 Hydraulic Fluid. The hydraulic fluid to be used during shop testing and to flush the system after installation shall be Mobile DTE13M hydraulic oil. 2.3 SPARE PARTS The contractor shall f urnish spare parts (with the manufacturers name and part number) in the quantities listed below: Item Quantity Rod Wiper 2 O-Ring Seals 2 sets Piston Rod Rings 2 sets 2.4 SHOP ASSEMBLY AND TESTING The hydraulic power syste m shall be completely shop assembled and tested insofar as possible using temporary piping and wiring to determine the correctness of fabrication. Shop tests shall be made in the presence and of a representative of the Contracting Officer, unless otherwis e waived in writing. Upon satisfactory completion of the tests, preliminary acceptance will be made by the Contracting Officer. 2.4.1 Cleaning. Extreme care shall be taken during shop assembly to avoid inclusion of foreign materials into the equipment . The interior of the cylinder piping shall be cleaned with lint free cloths and flushed with oil at a minimum velocity of 15 fps, which has passed through a 10-micron filter. 2.4.2 Cylinder Tests. The cylinders shall be filled with hydraulic oil, bled of all air and tested in the shop as follows: The piston shall be blocked approximately 1-1/4 inches from the fully extended position and a pressure of 1500 psi shall be imposed on the cap end for five minutes. The leakage past the piston shall be collec ted and measured and shall not exceed 12 fluid ounces. The Technical Representative shall be present at the test, unless otherwise waived in writing. 2.5 PAINTING 2.5.1 Surface Preparation. Surface preparation shall be power tool or brush-off b last cleaning conforming to SSPC-SP 3 or SP 7.
