预计本SAE推荐规程仅为车辆/变速器应用综合评估的一个步骤。仅此文件不足以“适当注意”以确保防止高速扣押或其他高速问题。高速旋转、高速不平衡和润滑实践的总体目标是评估手动变速器，手动变速器可能安装在允许高速行驶的旧车辆上。本文件分为四个部分，包括:预试验润滑评估；高速旋转前试运转；高速旋转试验；以及高速输出轴不平衡。

It is anticipated that this SAE Recommended Practice will be only one step in a comprehensive evaluation of the vehicle/transmission application. This document alone is not adequate "due care" to insure against high-speed seizure or other high-speed problems.The overall objective of the high-speed spin, high-speed unbalance, and lubrication practice is to evaluate manual transmissions which may be installed in vehicles old into countries where high vehicle speeds are permitted. The document is segmented into four parts which include: pretest lubrication evaluation; pre-high-speed spin test run-in; high-speed spin test; and high- speed-output shaft unbalance.
