First remove the pump from the equipment to be repaired.<\/span> Use the pump disassembly procedure from the manufacturer.<\/span> Use appropriate equipment and adhere to safety procedures as confirmed by the manufacturer.<\/span> Attach the pump to the demolition or table for disassembly (the pivot part is below) (Figure 3.47 left).<\/span> With sharp metal scratching apparatus, a pencil or magic marker (special markers), draw a line \/ mark on the pump from the port end cover<\/i> to the end shaft cover<\/i> .<\/span> This line will work to flatten the components when you re-assemble them.<\/span> Remove the cover bolts and washer<\/i> on a single unit<\/i> or threaded rod<\/i> on multiple units (Figure 3.47 right).<\/i><\/span> Remove the end cover port<\/i> and thrust plate<\/i> by inserting a screwdriver or push rod (Figure 3.48 left).<\/span> Make sure you do not scratch the surface of the engine.<\/span> Thrust plate<\/i> and roller bearings<\/i> remain inside the end cover port<\/i> when released as shown in Figure 3.48 on the right.<\/span> Remove the thrust plate<\/i> and check for wear<\/i> (wear).<\/span> Lift the housing gear<\/i> carefully so as not to damage the surface of the engine (Figure 3.49 left).<\/span> Use a screwdriver or pusher if necessary.<\/span> Remove the drive gear<\/i> and idler gear<\/i> carefully so as not to damage the surface of the machine (Figure 3.49 right).<\/span> Keep gear<\/i> united.<\/span> You have to re-assemble it in pairs because the gear<\/i> works simultaneously.<\/span> In the multiple section unit<\/i> , disconnect the carrier bearing<\/i> (Figure 3.50 left).<\/span> Use a screwdriver or pusher if necessary.<\/span> Make sure you do not damage the surface of the machine.<\/span> In the multiple section unit<\/i> , remove the connecting shaft (Figure 3.50 right).<\/span> Lift the gear housing<\/i> carefully so as not to damage the surface of the machine (Figure 3.51 left).<\/span> Use a screwdriver or pusher if necessary.<\/span> Remove the drive<\/i> and idler gear<\/i> from the<\/i> shaft cover<\/i> carefully so as not to damage the surface of the machine (Figure 3.51 right).<\/span> Keep gear<\/i> united.<\/span> You must install the drive<\/i> and idler gear<\/i> back in pairs, as both work together.<\/span> Remove the thrust plate<\/i> and check if it has experienced severe wear (Figure 3.52 left).<\/span> Bearing<\/i> must remain on its cover<\/i> .<\/span> If not, or if removable by hand, remove the end cover port<\/i> .<\/span> Check the thrust plate<\/i> if you are wearing or are slippery.<\/span> If you plan to change the bearing<\/i> , reverse the end cover port<\/i> and release the snap ring<\/i> on the bearing shaft<\/i> (figure 3.52 right).<\/span>
