1. INTRODUCTION 介绍
A. The data in this subject comes from Boeing Process Specifications BAC5001-6, BAC5001-7, BAC5001-9 and BAC5001-10. Access to the Boeing Process Specifications is available.
本主题中的数据来自波音工艺规范 BAC5001-6、BAC5001-7、BAC5001-9 和 BAC5001-10。可查阅波音工艺规范。
B. The data is general. It is not about all situations or specific installations. Use this data to help you write minimum requirements.
数据具有通用性。并非针对所有情况或特定安装。使用此数据可帮助您编写最低要求。
C. Refer to SOPM 20-00-00 for a full list of all the vendor names and addresses.
有关所有供应商名称和地址的完整列表，请参阅 SOPM 20-00-00。
2. GENERAL 通用
A. Refer to the overhaul instructions for the approved lubricant for the threads. If the overhaul instructions do not give the lubricant, refer to BAC5001-6, Table 1.
请参考大修说明，了解螺纹所需的批准润滑剂。如果大修说明中没有提供润滑剂，请参阅 BAC5001-6，表 1。
B. Lubricate O-rings and gaskets by the overhaul instructions or BAC5506 (SOPM 20-50-06).
按照大修说明或 BAC5506 (SOPM 20-50-06)润滑 O 形圈和密封垫。
C. Install and tighten the fittings, couplings or clamps by standard industry practices, the overhaul instructions, and the instructions in BAC5001-6, BAC5001-7, BAC5001-9 and BAC5001-10, as applicable.
根据行业标准做法、大修说明以及 BAC5001-6、BAC5001-7、BAC5001-9 和 BAC5001-10 中的说明（如适用）安装和拧紧接头、联轴器或夹具。
D. Use the torque values as specified by the overhaul instructions. If the overhaul instructions do not give the torque or tell you to tighten to standard torque, use the torque values shown in Figure 1 thru Figure 4, or BAC5001-6 thru BAC5001-10, as applicable. To help you find the torque for hydraulic fittings such as unions, reducers, valves and plugs, use these guidelines:
使用大修说明书规定的扭矩值。如果大修说明中没有给出扭矩或告诉您拧紧到标准扭矩，请使用图 1 至图 4 或 BAC5001-6 至 BAC5001-10 （如适用）中所示的扭矩值。为帮助您找到接头、变径接头、活门和堵盖等液压接头的扭矩，请使用以下指南：
(1) Find the thread size of the fitting. This can be measured on the actual part, or identify the fitting part number and refer to the part specification or standard, which will give the thread size and the related tube size (which can be part of the fitting part number).
确定接头的螺纹尺寸。这可以在实际零件上测量，或者确定接头件号和参考零件规格或标准，其中会给出螺纹尺寸和相关管道尺寸（可以是接头件号的一部分）。
(2) Find the material of the fitting, and also of the mating part (the part with the threaded hole). If the materials of the fitting and the mating part are different, note the softer material, such as aluminum compared to steel or titanium. For the purposes of this analysis, consider steel and titanium to have the same hardness.
查找接头的材料，以及配合零件（带螺纹孔的零件）的材料。如果接头和配合零件的材料不同，请注意较软的材料，如铝相对于钢或钛。在本分析中，将钢和钛视为具有相同硬度。
(3) Find the torque in Figure 1, Figure 2, Figure 3 or Figure 4, or BAC5001-6 thru BAC5001-10, as applicable, for the noted material and thread size or tube size.
根据图 1、图 2、图 3 或图 4 或 BAC5001-6 至 BAC5001-10（视适用情况而定）中所指出的材料和螺纹尺寸或管道尺寸，找出扭矩。
