An Improved Air Pressure Gauge For The Brakes Is Now Used On Certain K And K Series 2 Motor Graders {7450, 7451}
- Motor Grader:
- 120KSeries 2 (S/N: SZS1-UP)
- 120K (S/N: SZN1-UP; JAP1-UP)
- 12K (S/N: JJA1-UP)
- 140K (S/N: JPA1-UP; SZL1-UP)
- 160K (S/N: SZM1-UP)
Description of Change: Improvements in the manufacturing process have been made on the air pressure gauges of certain Motor Graders. The change will increase accuracy and indicate a zero position when no air pressure is applied.
Adaptable To: The improved 304-6958 Air Pressure Gauge is adaptable to machines and effective in production with the machines listed in Table 1.

(S/N: SZS572-UP) |
| 12K | (S/N: JJA1-3166) | (S/N: JJA3167-UP) |
| 140K | (S/N: JPA1-3759; SZL1-3159) | (S/N: JPA3760-UP; SZL3160-UP) |
| 160K | (S/N: SZM1-620) | (S/N: SZM621-UP) |
Note: The improved 304-6958 Air Pressure Gauge uses the same part number as the former gauge. After installation, test the gauge to verify that the replacement will indicate a zero position when no air pressure is applied.
