9.5.   Assembly of Disposer

1.  Clean all components carefully. Wipe the surface of the motor (P1) upper flange and its shaft. 

Make sure that there is no dust or grease residue. 

2.  Make sure that the motor shaft key (P30) is in the correct position. Apply a thin layer of 

Disperator special grease (P26) on the motor shaft.

3.  Wipe the carrier (P2) clean on the inside and outside.

4.  Mark onto the motor shaft the depth of the hole in the carrier (P2). From the top of the motor 

shaft, this measure is 38 mm for models 510, 515, and 48 mm for model 520, and 58 mm for 

models 530, 550 and 575. Carefully press the carrier (P2) onto the motor shaft all the way down 

to the mark. If hand power is not enough, use the axle screw (P12) as a mounting tool. If needed, 

use the rotary shredder (P10) as a handle to prevent the carrier from rotating.

5.  On the end shield (P3), clean the center hole for the axle seals (P5). 

6.  Place the washer (P4) in the end shield with the flange facing towards the motor (see the sketch 

below under item 8, where the parts are seen with the end shield placed upside down as on the 

photo to the left). 

7.  Grease the sealing face of this center hole in the end-shield (P3) with special grease (P26).

8.  To avoid damaging the seals (P5, 2pcs), press each seal one at the time into position in the end 

shield using a tool (for example a shaft end or other round bar, see below photo) that has the 

same outer diameter as these seals. The seals shall be placed with the opening and stainless 

spring upwards towards the washer (P4) according to the below sketch. 

9.  The seals are fixated by fitting the locking ring (P6) into the groove in the end shield (P3) 

according to the above sketch under item 8. Tap on this ring to ensure that it is seated properly 

in the groove in the end shield. 

10.  With a clean and soft putty knife fill the grooves along the sealing lips in the axle seals (P5) with 

special grease (P26). Be sure no dirt or particles happen to fall into this greasing. 

11.  With a clean soft cloth lubricate a thin layer of special grease (P26) on the carrier (P2) sealing 

surface for the 

axle seals (P5)

. 

12.  With reference to section 9.4, item 13 above, refit the end shield (P3) so that its outlet ends up 

180° offset from the motor (P1) terminal box for cable connection.

 Take great care so that the 

lips on the axle seals 

(P5, 2pcs)

 not

are damaged. For disposer models 510, 515 and 520 secure 

the end shield with tightening torque 47 Nm on the four screws (P7), and for models 530, 550 

and 575 secure the end shield with tightening torque 81 Nm on the four screws (P7). 

13.  Grease the sealing lip of the V-ring seal (P8) and its seal washer (P4) using special grease (P26). 

Fit the V-ring seal over the carrier (P2) with its seal lip against the seal washer (P4).
