Description of Change: Improved roading lights are now available for Medium Wheel Loaders. The new signal and lamp groups have improved the service life of the bulb. A new bracket for mounting the roading lights has been designed. The new design increased service life by reducing vibration of the lamp group.

New Design

The new design is adaptable to the following machines:

  • 950H (S/N: K5K1-2526; M1G1-1782; N1A1-3228)

  • 962H (S/N: K6K1-403; M3G1-541; N4A1-1261)

  • 966H (S/N: A6D1-2132; A6G1-3944)

  • 972H (S/N: A7D1-764; A7G1-1276; WLA1-9)

  • IT62H (S/N: M5G1-475)

  • IT38H (S/N: JNJ1-UP)

  • 938H (S/N: LKM1-568; MJC1-639)

Note: Field installation on the 938H will require the addition of two 090-8247 Blocks. Install one on the right-hand side and one on the left-hand side of the machine. Refer to Illustration 3 below.

The new design is effective in production on the following machines:

  • 950H (S/N: K5K2527-UP; M1G1783-UP; N1A3229-UP)

  • 962H (S/N: K6K404-UP; M3G542-UP; N4A1262-UP)

  • 966H (S/N: A6D2133-UP; A6G3945-UP)

  • 972H (S/N: A7D765-UP; A7G1277-UP; WLA10-UP)

  • IT62H (S/N: M5G476-UP)

  • 938H (S/N: LKM569; MJC640-UP)

Note: The new design will be effective in Piracicaba for the 938H in August 2009.
