PISTON PUMP NEUTRAL ADJUSTMENT CONTINUED
3. Start engine and using ET enter Transmission Stall Test.
4. Loosen lock screw (Figure 29, Item 1) on set screw (Figure 29, Item 2).
5. Adjust set screw (Figure 29, Item 2) until pressure at X1 port is within 30 psi (207 kPa) of pressure at X2 port.
N OT E
Adjustment of set screw is sensitive and adjustment can easily change as lock screw is
tightened.
6. Maintain position of set screw (Figure 29, Item 2) and tighten lock screw (Figure 29, Item 1).
7. Verify pressure readings are still within 30 psi (207 kPa) of each other.
8. Stop engine, exchange gauges on both ports, and verify readings are within 30 psi (207 kPa) of each other.

9. Stop engine, relieve hydraulic system pressure (WP 0162), and repeat steps 18 on remaining hydrostatic
pump.
10. Stop engine, relieve hydraulic system pressure (WP 0162), and remove pressure gauges and hoses.
11. Install cab floor plate (WP 0205) and bottom guards (WP 0156).

SPEED SENSOR ADJUSTMENT
00031
The machine ECM uses data from the engine speed sensor when performing the underspeed function. The sensor
produces a signal that varies as engine speed changes. The signal frequency is one pulse per flywheel tooth.
Refer to WP 0007 for detailed description of speed sensor. Refer to WP 0058 for speed sensor adjustment proce-
dure.
