About this file
This document is a detailed technical manual for the hydraulic cylinders of a Terex T300-1 94' Boom Mobile Crane, specifically focusing on maintenance, service, and reassembly procedures for various boom and hoist cylinders. The manual provides comprehensive technical diagrams and instructions for disassembling, inspecting, and reassembling hydraulic cylinders, with specific guidance on handling components like piston rings, seals, and glands. Key maintenance instructions include daily and weekly wire rope inspections, cautions about potential piston ring breakage during assembly, and detailed steps for cylinder disassembly, including using Loctite Grade 242 for securing components and torque specifications for various fasteners. The document emphasizes the importance of cleanliness during maintenance, recommending a dust-free atmosphere and plugging all ports until hose connections are made, and provides visual breakdown illustrations of extend cylinders, hoist cylinders, and boom sections with detailed parts lists and part numbers.

SERVICE AND ADJUSTMENTS
WIRE ROPE AND REEVING
MAINTENANCE All wire ropes in active service should be inspected DAILY along with spooling, sheaves, wedge sockets, and any other wire rope fittings for damage. Once WEEKLY a thorough wire rope inspec tion should be made by a competent inspector. A record should be kept of the inspections on page 4-5.
Refer to ANSI Standard B30.5 for guidelines covering the inspection, maintenance, repair and replacement of wire rope. Worn, kinked, birdcaged, fatigued or other wise damaged wire rope must be removed immedi ately. Wire rope, when properly installed, lubricated and employed, will give many hours of satisfactory use.
Whereas, a new piece of wire rope can be immediately ruined if misused.

Replace or repair any items found to be in unsatisfac tory condition.
In addition to damage such as kinking, crushing, and broken wires, factors such as corrosion, abrasion, pit ting, peening, and scrubbing of outside wires, reduction of rope diameter, the condition of other components and proper lubrication are considered. Refer to Section 9 for wire rope lubricating procedures.
Before installing a new or replacement rope, make cer tain the rope to be used is the proper type and size.
The wrong rope will not function properly and may even be dangerous.

STRENGTH. The inner wires are generally the first to fail on this class of rope, making it very difficult to inspect, as broken wires cannot be seen. Refer to ANSI B30.5, Section 5.24 for the necessary inspection procedure and replacement criterion.
If non-rotating or spin resistant rope is used on this crane, the rope must be replaced if two or more wires are found broken in one lay of the rope.
