11 Remove ‘O’ ring.
12 Unscrew Allen screws and remove the near plate from bearing bracket.
13 Remove the shaft seal key.
14 Pull the shaft seal off the shaft.
15 Pull the shaft seal seat carefully out of the recess of the rotor hub.
16 Remove key from the shaft and remove screws.
17 Pull the bearing cover with oil sealing ring off the shaft.
18 Remove the paper gasket.
19 Pull out the shaft with bearing bracket, allowing inspection of the bearing.
TASK 2: Cleaning of centrifugal pump
1 Clean all the parts by wiping with soft waste cloth.
2 Use cleaning oil to clean the parts.
3 Clean the recess in the rotor.
4 When fitting the seat remove the pretective coating if any without scratching the upper surface.
TASK 3: Assembling of a Centrifugal pump
1 Place O-ring on the collar of the rot housing and press into place in the inlet of the pump casing.
2 Fasten rear plate to the bearing bracket with allen screws.
3 Lead the shaft into the bearing bracket.
4 Mount oil sealing ring in bearing cover.
5 Place paper gasket on the bearing cover and lead cover over the shaft.
6 Fasten with Screws.
7 Mount the key in the shaft.
8 Dip the outer rubber ring of the seat into soapy water.
9 Press the seal into place with the fingers and check that all the parts are correctly embedded.
10 Lubricate the inner diameter of the slide ring rubber bellows with soapy water and push it over shaft.
11 Push the slide ring over the shaft with hand. (Note : If rubber bellows is tight, use a fitting tool and take care
that the slide ring is not damaged). (If the carbon ring is not fixed, it is important to check that is fitter correctly.
12 The carbon ring can be held by a little grease.
13 Fit key for rotor is the shaft and lead the rotor over the shaft and all the way to the shoulder of the shaft.
14 Place the two guide pins is front of the rotor.
15 Place the impeller on the rotor in such a way that the two guide pins are located in the impeller looks.
16 Secure the impeller with a disc, a lock washer, and an allen screw.
17 Place the O-ring that seals between pump casing and bearing bracket on the bearing bracket where it can be
held with a little silicone grease.
18 Lead the bearing bracket into place and faster with screws.
19 Mount filling and drain plug.
20 Fill the bearing bracket with oil (SAE 15W40) until half the shaft is covered.
21 When the pump has been assembled, check that the shaft rotates freely.
