DESCRIPTION:

BT PRIME MOVER HMX/RMX SERVICE MANUAL – PDF DOWNLOAD

• Threaded fasteners like bolts, nuts, cap screws and studs are made to specifications that describe the mechanical strength and hardness of the fastener. A fastener used in a design application is selected according to its specifications. The Prime-Mover Company buys parts from many countries. There are several standards used by these countries in the manufacture of threaded fasteners. Many of these fasteners are similar, but cannot be used as direct replacement.
• Service persons must use replacement fasteners that have the same specifications. Fasteners made to each specification have identification marks for that specification. This specification is commonly called “Grade” for SAE standards and “property for metric standards. This section describes the identification of some common fasteners.
• The metric system used by BT Prime-Mover is described as SI (International System of Units, also called SI in all languages). The 81 system of measurement is described in ISO Standard 1000, 1973.
