Mounting of new stator 

J 205, J 405:

 (Figure 22, 23) Block up the new sta-

tor and make sure that the motor housing can be fully 

pushed down onto the stator. Protect the stator insula-

tion from damages and fold stator cables together in 

two groups and put them into a position so they can 

easily be pulled up through the holes/openings in the 

motor housing when stator is mounted. Avoid cables 

to get in contact with the hot motor housing during as-

sembly. Make sure the motor housing is secured by the 

lifting crane and that it can be fully lowered on to the 

stator. 

Use Two LP-gas flames to heat the housing till about 

198º to 250ºC (388º to 482ºF). With two 25 mm nozzles 

this will take about one minute. 
Rotate the motor housing into a position, so the sta-

tor/ thermal/control cables can be pulled up smoothly 

through the motor housing and later pulled through and 

assembled on the terminal plate/upper bearing bracket.

A stator lifting tool may be used for an alternative way 

to lift  back the new stator into the motor housing. 

Check section 11 for part No. (Figure 22)

When the stator has been mounted the motor housing 

may be cooled by compressed air.
Grease and mount the o-ring for the upper bearing in 

the upper part of the motor housing on J 205.

J 604:

 (Figure 22, 24, 25) Block up the motor housing 

and make sure that the new stator can be fully lowered 

into the motor housing. Protect the stator insulation 

from damages and fold stator cables together in two 

groups and put them into a position so they can easily 

be pulled up through the holes/openings in the motor 

housing when stator is mounted. Avoid cables to get 

in contact with the hot motor housing during assembly. 

Make sure the stator is secured by the lifting crane and 

that it can be fully lowered into the motor housing. 

Use Two LP-gas flames to heat the housing till about 

198º to 250ºC (388º to 482ºF). With two 25mm nozzles 

this will take about one minute. 
Rotate the stator into a position, so the two threaded 

holes used by the locking key are placed on each side 

of the axial groove in the motor housing (2xMC6S).
