We will start our wheel assembly instructions by reviewing the assembly of the sections of sails, sail ribs and inner and outer wheel bands.
WHEEL SAIL SECTION ASSEMBLY |
| Slide a sail rib (#101) over the small end of the
sail toward the large end until it fits into the rectangular hole in the sail (#100), as
indicated in the drawing. Repeat this process for all 18 sails. Lay three sails in position as shown in drawing. Connect the inner band (#35) to the sail tab with bolts and lock nuts. Do not tighten the lock nuts yet. Note the distance that should extend in dimension 2 table. Slide the outer band (#34) throough the rectangular hole in the sails until bolt holes of outer band match the bolt holes in the sail ribs. Dimension 1 indicates the correct measurement when #34 is installed correctly. Tighten all lock nuts in wheel section and repeat this procedure until all 6 sections are completed. |

| Install
the 12 wheel arms into the hub assembly of the crated motor. The end of the #736 wheel
arms with the square head screws into the hub. Use a wrench with smooth jaws to tighten
them into the hub. Never use a pipe wrench, as it will ruin the galvanized coating and
make the arms susceptable to rust. Stop the first arm of each pair 1/4 turn from tight, so
it will not interfere with the installation of the second arm. Then after the second arm
is tight, tighten the first arm so that the tabs are parallel to each other so the offset
ends are aligned to receive the inner wheel band. The outer ends of the wheel arms will all stand straight out and in line, allowing them to slip through the holes in the outer wheel bands without bending. Do not try to spring the arms out of their normal position when putting on the wheel sections. The arms cross at the inner band and the cross ties stand at right angles to the band so they cross the inner band. If the inner bands do not fit into the depressed area of the arm crosses, you have not turned the arms to the right position, or you have an arm in with the wrong end screwed into the hub. It is important for them to be in right so the wheel can run true. Do not attempt to bend these arms or the threaded section. Be sure to follow these instructions completely. With a pair of wheel arms mounted in the front holes of the hub facing down, place a section on so the ENDS OF THE WHEEL ARMS GO THRU THE OUTER HOLES OF THE SECTION. Rotate the wheel to the left, and place a section onto the arms mounted in the rear holes of the hub. The wheel arms for this section will go through the outer holes of this section. The third section will go on the arms that are from the front holes on the hub. BE SURE YOU ONLY PLACE THE NUT ON 2 TO 3 THREADS AS YOU INSTALL SECTIONS. IF YOU TIGHTEN THEM UP TOO MUCH, THE LAST SECTION WILL NOT FIT. Rotate the 3 assembled sections to the top so they will balance, and install the 4th section which goes on the arms from the back holes of the hub. Rotate again to install the fifth section onto the front holes of the hub. When you put the sixth and last section in place, the point where the first section meets the sixth requires you to temperarily remove the outer end of the first band and place the end of the sixth section band on first. Then replace the first section band so each joint is assembled with the same lap. VERY IMPORTANT THAT YOU NOT PLACE THE LAST SECTION OVER THE OUTSIDE OF THE FIRST SECTION END. IT WOULD CAUSE YOUR WHEEL TO NOT BE TRUE. After all six wheel sections have been assembled to wheel arms and all the inner bands are bolted together, you will start to tighten each set of nuts on the outer bands a couple turns at a time. Then rotate the wheel and tighten the next set a couple turns. Continue this until all the nuts are tightened fully. The Aermotor windmill wheel is a tension type wheel and when it is properly assembled, it forms a very rigid and strong wheel of high efficiency and strength. Now it is time to fill the gear case with oil. Remove the helmet and put in the proper amount of oil. The ( X ) 6' mill requires 1 quart, ( A ) 8' requires 2 quarts as does the ( B ) 10' mill. The 12' ( D ) requires 4 quarts, the 14' ( E ) requires 8 quarts, as does the 16' ( F ) size mill. This will be enough oil to properly lubricate the mill for a year. It is recommended that a NON-DETERGENT - ZERO WEIGHT OIL BE USED. It will flow freely to all areas needing oiled and will remain fluid in cold weather. Replace the helmet and be sure it is fully seated. The inner flange should be inside the gear case casting to assure that the oil does not splash out. Install the nut to hold the helmet in place and keep rain out. Pump Pole |
| The pump pole is made of wood
approximately 14' long. Being of wood, if something gets hung up or catches, the wood pole
will break instead of breaking something in the gear case. It is your safety link. DO
NOT TRY TO ELIMINATE IT AND PUT A CHAIN IN ITS PLACE. The cost of the damage possible
will outweigh the inconvenience of replacing a broken wood pole if necessary. Connect the wood pole to the #171 pump rod swivel. Turn your wheel until the pump pole is at its lowest point of the stroke. Screw the #62 rod to pump pole connector onto the rod, and pull the rod up about 2" and connect the #62 to the wood pole. This will prevent the plunger from hitting the bottom check of the cylinder. Turn the wheel completely around to be sure it also does not hit at the top, and that there will be no problem with the mill stroke length in reference to the cylinder stroke area. Stroke length change. The mill is assembled using the long stroke at the factory. The capacity tables are all based on the long stroke. Changing to the short stroke will decrease the capacity of water pumped by about 25%. It will allow you to pump a little deeper than the chart says for the cylinder size with your size mill. To change your Aermotor windmill to the short stroke, turn the large gears until the pitmans are at the bottom of the stroke. You may need to place a piece of wood under the edge of the #608 yoke to support the weight on the pump rod. A piece of wood the thickness of the pump pole is about right. Remove the cotter pin at one end of the #522 shaft that goes through the guide wheel. Push it out of the pitman arm, yoke and guide wheel. Turn the large gears until the lower ends of the pitman arms are above the rim of the gear case. Remove the cotter pins and #622 bolts, and remove the pitmans from the gears. Turn the large gears about 1/2 turn, until the other set of pitman bosses on the large gears is above the rim of the case. These are the bosses that are closest to the center of the gear. Place the pitman arms onto the short stroke bosses, and reinstall the #622 bolt and cotter keys that held the pitmans to the long stroke bosses earlier. Rotate the gears until the pitmans are near the bottom of the stroke and again use the piece of wood to support the base of the #608. Replace the #522 shaft through the LOWER HOLES IN THE UPPER ENDS OF BOTH PITMAN ARMS, the yoke and the guide wheel and insert the cotter key that goes into the end of the #522. After changing the stroke, be sure the oil ring #507 rolls on the large gear at the bottom of the stroke. Turn the wheel to be sure everything is operating freely before replacing the helmet on the gear case and returning the mill to service. IMPORTANT When changing the stroke, BOTH ends of the pitman arms will change location. The short stroke requires the large end to be on the inner most boss on the large gear, and the inside hole on the opposite end to be connected to the #522 shaft. |

Windmill Care |
Home |
Aermotor windmills are the ideal livestock water source for cattle and sheep, whether on the open range or ranch pasture. We offer the largest selection of Aermotor windmills for stock watering (domestic Aermotor windmills, imported Fiasa windmills, and factory reconditioned used Aermotor windmills ) as well as windmill repair parts to keep your present windmills operating efficiently. For over 35 years we have provided windmills, windmill towers, sucker rod, cylinders, cup leathers, and other windmill supplies to enable ranchers to use wind power to pump water. Windmills allowed the settlement of the old American west and still offer an alternative energy source just as efficient and reliable as when first used in the early 1800's.
