‌Woodward TG-13 Speed Governor Operation Manual‌

‌Model:‌ 8516-038 (Cast Aluminum Mechanical-Hydraulic Governor)

‌Pre-Operation Checks‌

‌System Verification‌
- Confirm governor is installed per ‌NEMA 12/13‌ enclosure ratings with ≥50mm clearance for ventilation1
- Verify hydraulic oil level (ISO VG 32) within sight glass range
- Check linkage alignment: Output shaft-to-steam valve tolerance ≤0.15mm
‌Safety Interlocks‌
- Ensure overspeed test device (OTSD) is disabled if model ‌9904-814‌ is installed4
- Validate emergency trip circuit continuity (24V DC monitoring loop)

‌Startup Sequence‌

1. Open oil fill port (1/4" NPT) and fill until level reaches midpoint of sight glass

2. Manually rotate drive shaft 3-5 revolutions to prime oil pump

3. Verify oil pressure: 2.8-3.2 bar (40-45 psi) at rated speed

‌Step 2: Speed Adjustment‌

‌Control‌	‌Procedure‌	‌Tool‌
Speed Setpoint	Turn knob clockwise to increase speed	6mm hex key
Droop Adjustment	1 rotation ≈ 4% speed droop change	Flat-blade screwdriver
