Reclamation safety requirements meet or exceed OSHArequirements. The Contractor shall not require any workmen employed in the performance of this contract (including Reclamation employees) to work under conditions which are hazardous or dangerous to the employee's health or safety. TOOLS The contractor shall provide all required tools, instruments, or gages for disassembly, inspection, repair, and reassembly of the compressor.

CENTAC COMPRESSOR OVERHAUL The CENTAC is a two stage, high efficiency centrifugal air compressor constructed with a cast iron vertically split casing assembly. The unit has a casing cover and a gear case cover to allow access to inspect bearings and gears and to set clearances for the impeller/diffuser. The single forging helical bull gear runs on two oil lubricated bearings and drives the two rotor assemblies. Each precision balanced rotor assembly consists of a helical geared pinion shaft, a high efficiency stainless steel open impeller and a removable thrust collar. The impeller and the thrust collar are secured to the shaft using a precision polygon attachment. Each stage is provided with a plain bearing assembly, thrust bearing assembly, and shaft seal assembly. The pinion plain bearing assemblies are precision machined, fixed geometry, journal bearings with one piece steel backed babbitt which are pressure fed with lubricating oil. The pinion shaft seal assemblies are cartridge type. They are mounted in the plain bearing housing behind the impeller. Each cartridge consists of three one-piece fully floating noncontact carbon rings. One ring is used as an air seal, two as an oil seal. Air is injected between the two oil seal rings to insure oil free compression. A vent to atmosphere is provided between the air and oil seals. The diffuser is cast iron with pinned on stainless steel vanes. It is located between each impeller and cooler. A noncontacting vibration probe is located next to each plain bearing to provide measurement of the radial vibration of the rotor assemblies. The fabricated steel baseplate with the integral lube oil reservoir is coated to resist corrosion. The baseplate supports the compressor casing, lube system, control panel, and has holes for mounting bolts. The compressor unit is a CENTAC, Type C15M2, 100 psig, 1600 CFM, and runs at a rated speed of approximately 3600 RPM. MATERIALS AND REPLACEMENT PARTS Materials or new replacement parts to be supplied must be manufactured of the same materials and to the same dimensions and tolerances as the original parts on the CENTAC (Ingersoll Rand) compressor. It shall be the Contractor's responsibility that these materials and new replacement parts meet this criteria and can be successfully installed into an existing unit and operate cohesively with existing gears, bearings, and shafts that did not require replacement. These materials and new replacement parts includes the following: 1) Complete gasket kit assembly (1 each) 2) Plain bearing assembly (2 each) 3) Thrust bearing assembly (2 each) 4) Bull gear bearing assembly (2 each) 5) Shaft seal kit (first stage) (1 each) 6) Shaft seal kit (second stage) (1 each) Existing parts that are replaced with new parts shall become the property of the Contractor. At the Contractor's option, these parts may be salvaged or may be disposed of onsite. REQUIRED WORK ITEMS Work to be performed by the Contractor includes the following: 1) Disassembly of the compressor as required to complete the work. 2) Clean, inspect, and balance the rotor assembly (first and second stage). Determine if rotor assembly is within the manufacturers recommended tolerances, needs to be repaired, or needs to be replaced. 3) Clean, test, and repair coolers (first and second stages). 4) Completely reassemble the compressor unit. Reassembly shall include installation of new gasket kit, plain bearing assemblies, thrust bearing assemblies, and bull gear bearing assemblies, and shaft seal kits. 5) Check and measure clearances and tolerances for all movable parts and/or assemblies. 6) Oversee start-up procedures and testing; including operation at "no-load" and at "full-load". 7) Make minor adjustments to clearances and tolerances on an "as needed" basis after start-up procedures and testing has been completed. The contractor will be allowed to work any hours during the work week. However, any scheduled use of the overhead crane must be during normal work hours, Monday through Thursday, 6:30 a.m. to 5:00 p.m. WARRANTY The Contractor shall guarantee all new parts, materials, and repair work for a minimum of one year from date of installation.
