1) Model of the transmission case
Model of the transmission case is composed of code QR, number of shift gears of the transmission,
maximum transmission torque, characteristic code and structure specification number.
A complete transmission case model is as follows:
□ □ ○ ○○ □ □ □
Structure specification number
Characteristic code
Maximum transmission torque (kg·m)
Number of shift gears of the transmission case
Code QR
Among which, ○ indicates an Arabic numeral while □ indicates a letter.
2) Leaving factory number
Leaving factory number is composed of endnote of assembly part number (for that without endnote, us
AA), character code of the year of production, character code of the month of production, sequence
number of this transmission case among the transmission cases manufactured in that month and start
stop sign “*”. See Table 1 and Table 2 for check list of character codes of the year and of the month.
Complete form of leaving factory number of a transmission case is as follows:
*
□ □
□
□
○○○○○ *
Character code of the month
Among which, ○ indicates an Arabic numeral, □ indicates a letter and indicates an Arabic numeral or a
letter. The endnote locates at tail end of the part code, for a fundamental model, no endnote. The endnote
should be modified when modification is made to structure, dimension, material, heat treatment requirements
and surface treatment etc. of the part or assembly on the basis of original product. The English letter in the
code should be upper case letter (use in sequence with “A” as the first), in order to avoid confusion, do not
use “I”, “O” and “X”. When the modification does not affect interchangeability, use “A” as the first; when
the modification affects interchangeability, skip “A”, use “B” as the first.
