Notes are used to notify of installation, operation, ormaintenance information that is important but not safety related.Caution is used to indicate the presence of a hazard,which will or may cause minor injury or property damage if the notice is ignored.Warning denotes that a potential hazard exists andindicates procedures that must be followed exactly to either eliminate or reduce the hazard, and to avoid serious personal injury, or prevent future safety problems with the product.Danger is used to indicate the presence of a hazardthat will result in severe personal injury, death, or...

This manual will cover the installation of the basic driveconfigurations available for belt and gear-drive Hypro Centrifugal Pumps. Consult the manufacturer of yourtractor, motor or engine for additional information. Read all instructions and general safety information before attempting to install or operate the pump. > 3. To prevent start-up shock, a Spring should beattached to the Torque Chain. Secure end of the Spring to something solid in the same manner as using a Torque Chain alone. Series 9400 Pumps are designed for ease of installation and removal with tractor-mounted sprayers....

Nozzle Bodies Nozzle bodies with shut-off check valves are recom- mended to eliminate dripping from the spray tips when the boom valves are shut down. Boom Section Valves For rapid response and reliability,we recommend elec- tric plunger valves be used for boom control. The valves should be sized accordingly to minimize the pressure drop and maximize the flow rate. The boom tubing or hose should be sized accordingly to ensure that a pres- sure drop in the lines does not occur,causing inconsis- tent pressures at the nozzles. Agitation Flowmeter The centrifugal pump control contains a manual...

Engage the PTO clutch slowly and smoothly. Avoidsudden starts and fast clutching that may damage the drive section of the pump. Two Flow Control Valves are used - one in the agitation line and one in the line leading to the boom or spray gun. This permits controlling agitation flow independently of nozzle flow. > To adjust the sprayer (regardless of power source - PTO, belt or pulley), follow these steps:1. Prime the pump with all valves open. 2.Close Control Valve and Agitation Line Valve; thenopen the Boom ShutOff Valve.3. With the pump running, open the Control Valve untilthe Pressure...

Remove plastic back cover flange. Knock seal outfrom back with a hammer and screwdriver.] > 3. Remove stationary seat and boot by prying out withtwo small screwdrivers in manner similar to impeller removal. 1.Lightly lubricate the shaft for easier removal of theseal. Using two screwdrivers positioned opposite each other, pry the rotary portion of the seal from the shaft (See Figure 13).2.[ The seal will be damaged by removal in this manner.Anew seal and rubber gasket must be used when the pump is reassembled. Figure 13 Removing the Pump Seal > This step should not beperformed on the...

Figure 15 Figure 16 Pressing Bearings off Shaft Pressing Shaft and Bearings out of Mounting Flange 3.Using an arbor press, press the old bearings off theshaft (See Fig. 16). Because the center portion of the shaft has a thicker diameter than the ends, the bearings must be pressed off each end of the shaft.4.Support the inner races of the new bearings; thenpress the shaft into the new bearings.5.Pressing on the outer race of the new bearings,press the new bearings into the mounting flange.6.Install the internal retaining ring. > Be extremely careful with the new seal. Take special care not...

Gear Drive Unit ReassemblyBefore reassembling the gear drive unit, all partsshould be examined, and parts being reused should be clean and free of old oil. DO NOT WASH MAIN BEARING. 1.Place the gear case in the press, face up. Press themain bearing in (See Figure 22). Insert a large retain- er ring into the gear case.2.Place the gear case in the press, face up. Positionthe driver hub in the main bearing and press in, bot- toming on the main bearing. > On the 1000 rpm models, perform Step 5 beforeinstalling the driver hub. 1.Remove the drain plug from the bottom of the gearcase and drain the...

The weep holes in the mounting flange adapter must face down - towards feet. Do not force together. 12.Align holes and secure with gear case capscrews,using a 9/16" socket wrench.13.Replace the bottom drain plug in the gear case andremove the top fill plug. Fill the gear case with approximately 6oz. of Phillube SAE 80W90 GearOil. DO NOTOVERFILL. Replace the breather plug. DO NOTuse the side plugs on the gear case for a fill level indicator because doing so will cause you to overfill and damage the gear case.14.Install the pump seal, impeller and pump casing asdescribed elsewhere. 4.Slide a...

Idler Bearing Replacement 1.Remove the belt.2.Remove the idler bolt with a 15/16" impact socket. 3.Remove the idler pulley snap ring. 4.Press out the bearing using an arbor press. 5.To reassemble, reverse the procedure. Pedestal Bearing Replacement 1.Remove the belt.2.Remove the large pulley retainer ring and pulley.(For quick coupled models, remove the outer keeper ring and keeper balls.)3.Remove the bearing retainer ring and dust cover. 4.Using an arbor press, press out the driver hub andbearing assembly from the pedestal bearing bore.5.Remove the bearing snap ring from the shaft. 6.Using...
