EXPLANATION OF THE PROPELLER SHAFT CODE NUMBERS SHOWN ON CODE SHEETS
This code number actually describes the physical characteristic of the prop shaft assembly. The first Identifies the draign, the second, the second and
the third digits indicates the size of the joint, the fourth digit indicates tube diameter, the fifth, sixth and seventh Identifies the combination of ends and
fittings. Of primary interent to parts men is the last three digits which indicate the pin-to-pin or pin-to-end of shaft (overall) length. For example, 361
would indicate a shaft approximately 36.1" long and 427 would indicate that a shaft was 42.7" long. A more complete explanation of this break down is

To take a specific example, the production code part 2707013495, used in building the BC-225-D would break down as follows:
2707013495
2-identifies a Spicer type shaft
70-identifies a size 1700 Spicer joint
7-indicates a 3-1/2" tube diameter
013-indicates a standard double jointed w/slip yoke
495-shows that the shaft is 49.5" long
