Special Tools

Refer to manual 36405 for a listing of special tools required for maintenance or overhaul.

General Instructions


NOTICE

Use care in handling the governor to avoid damage to the drive shaft, oil seal, bearing and other internal parts or surfaces. Place the governor on supporting blocks and do not strike the drive shaft.


1. Drain oil, if any, from governor.

2. Clean exterior surfaces using a cloth moistened with cleaning solvent.

3. Do not remove or disturb the position of screws, brackets, etc., which function as adjustments; nor disassemble the various linkages further than required to effect removal unless replacement of component parts is necessary.

4. Do not remove press-fit parts such as bearings, locating (dowel) pins, oil pump check valves, pivot pins, etc., unless replacement is necessary or removal is required to effect disassembly or removal of other parts.

5. Discard, do not reuse gaskets, preformed packings (o-rings), oil seals, copper sealing washers, retaining rings, cotter pins, roll or spirol pins, etc., removed in the process of disassembly.

Repair Or Replacement

Repair of parts should be limited to removal of minor nicks, burrs or corrosion. Polish slightly corroded areas in mating surfaces using a fine (600 grit) abrasive cloth or paper and oil. Repair or rework to any greater extent is impractical and the part should be replaced.


NOTICE

Handle critical parts with extreme care so that mating edges and surfaces will not be damaged. Sharp edges of plunger lands, piston grooves, metering ports, etc., must be maintained. Rounded edges, nicks, or other damage to such edges will result in excessive internal leakage and/or decreased control sensitivity.


Cleaning

1. Clean critical parts by hand.

a. Pilot-valve plungers.
b. Pilot-valve bushings.
c. Compensation piston.
d. Servo piston.
e. Low-oil shutdown piston.
f. Needle valves.
g. Bypass valve.
h. Load-Control bushing.
i. ORS piston.

2. Clean resistor pack by submerging it in clean solvent and shaking it around. Blow dry with a jet of dry air.

3. Pressure wash castings and other parts.

Lubrication

Lubricate metal parts liberally with lubricating oil at time of assembly. Lubricate o-rings with petrolatum before installation. Also, lubricate any press-fit parts, bearings, and seals before installing.

Assembly

Assembly should be performed in a dust-free work area.

Replace any damaged or worn parts with new parts.

Replace o-rings, cotter pins, belloframs, and gaskets with new parts. Obtain new o-rings, gaskets, sealing washers, retaining rings, cotter pins, etc., to replace those removed during disassembly. Install retaining rings with sharp edge in the direction of the applied force.

Use "Ersin Multicore Activated Resin Core Solder" or equivalent when making electrical connections to solenoid coil (1106, Figure 7-16) or connectors (1126 or 1134). Use solder sparingly to avoid flow of excess solder through shield washers (1135) which may short circuit the terminals to ground.

Ballhead


Figure 5-31. PVP Adjustment


Figure 5-32. PVP Adjustment Procedure

1. Check the toe wear on the flyweights. Flyweight toes support the thrust bearing. Replace flyweights if there is a flat spot larger than 1/32 inch wide.

2. Check flyweight pins. Wear on pins indicate bad bearings in the flyweights. Replace both pins and bearings.

3. Check the thrust bearing by placing the bearing between the races and rotating it in your hand. If the bearing feels rough, replace it.

4. Check the main bearing by inserting two fingers inside the inner race and apply pressure while spinning the outer race with your other hand.

5. Check the pilot-valve plunger for nicks and wear. Replace the PVP if it has any nick in the control land larger than .001 inch.

6. Use a light and check inside the PVP bushing. Be sure there are no nicks on the control port.

7. Check the spring coupling by twisting slightly. The spring should not be loose. (See Figure 7-2).

8. Insert PVP and bushing in gear-bushing assembly and secure with snap ring.

9. Install spring coupling in flyweight head. The spring coupling has a missing tooth in its gear and fits in one position only.

10. Put bearing in gear-bushing assembly.

11. Lubricate o-ring and place it on gear bushing.

12. Place small spring and shutdown rod on PVP and secure with PVP nut.

13. Fasten flyweight head to gear-bushing assembly with eight screws.

14. Install flyweights in flyweight head.

15. Place adjusting spring and washer on shutdown rod.

16. Adjust PVP nut until PVP control land is centered in the control port of the PVP bushing. See Figure 5-31 and adjust the PVP nut until dimensions 'A' and 'B' are equal. Make the adjustment (Figure 5-32) while keeping a slight pressure on the flyweights in both directions. Pin nut (with cotter pin) in position once adjustment is correct.

17. Place thrust bearing on shutdown rod with race having largest hole on bottom.

18. Fit speeder spring in spring seat and place it on shutdown rod.

19. Place plug on top of speeder spring. This completes the ballhead assembly.

Power Servo


Figure 5-33. Assembly of Power Servos

1. Check piston and lightly remove any nicks or burrs with a small stone. Check shaft for wear and lightly polish with emery cloth if necessary.

2. Check cylinder for wear and remove nicks with emery cloth as required.

3. Insert piston in cylinder.

4. Press on oil seals just below flush, and press rod end on piston shaft. Secure with taper pin. For screw on type, screw on to 25 lb-ft. Then drill and pin with roll pin.

5. Put nut on tailrod and thread tailrod lift nut onto tailrod and fit the slotted end on piston shaft. Thread tailrod in until there is just enough clearance so tailrod lift nut can turn on piston. Tighten nut on tailrod lift nut to secure it in position.

6. Place gasket on cylinder and spring in cylinder.

7. Use jack screws or some type of guarded press to compress the spring guard on to cylinder and secure it with screws and washers.

8. Install scale.

9. Install spring, seal, and o-ring.

10. Check needle-valve seat for wear and install needle valve and washer. Screw in needle valve until it just bottoms. Then and back it off 2 turns.


NOTICE

Do not overtighten the needle valve as this damages the seat.


Power Case And Base (Figures 5-34 and 5-35)


Figure 5-34. Power Case

1. Check for wear in gear pockets. Shiny spots indicate a side load on driveshaft.

2. Check surface (base and column) for burrs, and stone if required.

3. Install both accumulator pistons and secure with snap rings.

4. Use an arbor press and install accumulator springs and seats, and secure with snap rings.

5. Install all pipe plugs, oil drain and oil gauge. Use Loctite on all threads.

6. Install idler gear and check for free movement.

7. Install pump gear and check for free movement.

8. Lubricate and install preformed packing on base end of power case.

9. Place base in position on power case and with 4 screws in center holes on each side of base, secure base to poser case. Tighten screws evenly a little at a time. Check alignment by placing driveshaft in position and turn it to check oil pump for free movement. If pump does not move freely, loosen screws in base and reposition slightly until driveshaft turns freely.

10. Insert the other 4 screws in base and tighten. Torque to 90 lb-in nominal.

11. Check driveshaft for wear in area where seal fits.


Figure 5-35. Drive Shaft and Base

12. Replace bearing on driveshaft with a new bearing unless none is available and the old bearing is not damaged too badly. See Figure 5-35.

13. Install gasket on seal and place into base.

14. Install driveshaft and secure with retainer plate and screws. Torque screws to 63 lb-in nominal.

15. Bend ears of retainer plate to secure screws.


Figure 5-36. Compensation System

17. Lay power case on its side and insert piston spring and spring seat in compensation cylinder on servo side of power case. Be sure both springs fit into ends of buffer piston.

18. Install gasket and power servo.

NOTE: When governor is on test stand and is at operating temperature, torque screws to 40 lb-ft.

8. Insert diaphragm assembly into cylinder for lube-oil system.

9. Install load-control supply valve in order as shown and in correct hole in column.

10. Replace bearings, if required, in end plate. See Figure 5-42. Use a brass punch through bearing end to remove end cap. Then reverse end plate and drive out bearing. Press fit new bearings into both end plates.
