![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/01_preparation_removal.png?mode=pad&width=600)
Usunąć wszelkie tuleje w celu wyeliminowania przyszłego zużycia się na styku miedzy tuleją, a
uchem do mocowania.

![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/03_preparation_cleaning.png?mode=pad&width=600)
Wygładzić nieregularności na powierzchniach otworów.
![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/04_preparation_min_max.png?mode=pad&width=600)
Różnica pomiędzy średnicą min. a max. w zużytych uszach musi mieścić się w granicach .06” (1.5 mm), aby tuleja była dobrze spasowana.
ATTENTION! If the worn lugs diameter at any point is 2 mm (.080”) or more over original lug diameter contact your dealer or Expander System. You will need oversized sleeves.

Final Check
![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/12_final_check_initial_torque2.png?mode=pad&width=600)
Po początkowym momencie obrotowym, kilkukrotnie przesunąć maszynę przez cały zakres ruchów i ponownie sprawdzić wartość momentu. Wartość momentu sprawdzać po 10, 40 godzinach lub w regularnych odstępach serwisowych, tak aby zapewnić odpowiednie posadowienie tulei rozprężnych.
![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/13_final_check_min_distance.png?mode=pad&width=600)
Sprawdzić, czy odległość pomiędzy podkładką napinającą, a uchem wynosi minimum 0,5 mm. UWAGA! Jeżeli podkładka napinająca styka się z uchem, skontaktuj się z dilerem lub firmą Expander.
Dismounting
![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/through-bolt/10_dismounting_through_bolt2.png?mode=pad&width=600)
Dismount bolt and washer. Tap the axle until the tension on the sleeves is released (use a piece of pipe between the axle and the mallet/hammer not to damage the threads). Remove the sleeve with a plier.
![](/globalassets/mediavalet/web-assets/pictures/expander/installation-instructions/through-bolt/11_dismounting_through_bolt.png?mode=pad&width=600)
Mount a short bolt and remove the axle using a sliding hammer, puller or similar. Bolt is normally fine pitch and sold by your dealer.
