MOTOR GP-WINDOW WIPER 2213450 - Caterpillar

and reversible. Both sides of the lower race must be "good". Only the side toward the bearing must be "good" on the upper race.10. Use a screwdriver and guide the spring seat and nut onto the pilot-valve plunger. Hold the spring seat and nut, and turn the plunger counterclockwise, threading seat and nut on until the nut is just below the top of the plunger.11. Release the nut and continue threading the spring seat down until it bottoms.Centering the Pilot Valve
1. Turn the pilot valve bushing until the port is visible through the base.2. Push on the flyweight toes to lower the pilot-valve plunger as far as possible. Check distance A (Figure 4-19). Pivot flyweights out as far as possible and check distance B. Distance A must equal distance B when flyweights have been moved from the extreme inward to the extreme outward position.3. If the control land is too high, use pilot-valve wrench 370109 to hold the spring seat stationary and turn the plunger clockwise to lower it. Should the control land be too low, turn the plunger counterclockwise while holding the spring seat stationary.4. When the pilot-valve plunger is centered (the same amount of opening in the port when the flyweights are full out as there is when the flyweights are clear in), tighten the nut by torquing it to 7.9 N m (70 lb-in) while holding the spring seat stationary.5. Check the setting again and, if correct, seal the inspection port by installing the plug with Loctite 228.6. Install the speeder spring onto the spring seat. Place tool 370109 under the spring seat and force the spring seat upwards and at the same time place the speeder spring on top of the spring seat. Hold the spring seat in place and push the spring down and turn clockwise to secure to the spring seat. When properly assembled, the pilot valve can be lifted by the speeder spring.Droop Assembly
1. Internal Droop: a. Assemble the droop bracket to the terminal lever. Do not tighten the screw.b. Align the droop bracket to zero droop, using tool 8995-085 as shown, aligning the pin in the droop bracket with the end of the tool. Tighten the screw. If droop is required for governor operation, it must be set after the governor is completely assembled, preferably on a test stand.c. The droop bracket pin may be installed to the right of the centerline if droop is desired in the governor (the farther right of centerline the more droop the governor will provide). The droop pin must not be set to the left of centerline.2. External Droop: a. Assemble the speed-adjustment and droop-adjustment shafts into the governor. (The droop-adjustment shaft has a smaller roll-pin hole than the speed-adjustment shaft.)b. Add the torsion spring (if used) to the speed-adjustment shaft, and the speed-adjustment lever. Notice that the 45-degree notch on the speed-adjustment lever must be up. Use the appropriate roll pin to attach the lever to the shaft. Connect the torsion spring to
