Información general
Un mal encajamiento o desalineamiento entre la columna de dirección (Douglas Autotech, número de pieza
WWS 38101-3425) y el soporte de montaje de la columna de dirección puede causar juego excesivo en el
volante. El juego excesivo se puede eliminar en el punto de pivote de la columna de dirección, agregando arandelas en cada lado de la columna de dirección, entre ésta y su soporte.
Desde el 1º de marzo de 2004, Western Star
empezó a usar un soporte de montaje de la columna de dirección
que mejora el encajamiento con la columna de dirección.
Si existe juego excesivo en el volante, siga las instrucciones provistas en "Procedimiento de ajuste de la columna de dirección", utilizando dos arandelas, número de pieza WWS 120394 (3/8 de pulg. x 0.065 de pulgada
de grueso) para eliminar el juego excesivo.
Procedimiento de ajuste de la columna de dirección
1.
Ponga los frenos de estacionamiento, apague el motor y bloquee los neumáticos.
2.
Retire los cuatro pernos sin tuerca y las arandelas que fijan la columna de dirección a la estructura de la
cabina, y descanse la columna de dirección sobre sus rodillas. Vea la Figura 1.
3.
Retire los dos pernos sin tuerca superiores y las arandelas (los más cercanos al volante de dirección) que
sujetan los soportes de montaje a la columna de dirección.
4.
Afloje los dos pernos sin tuerca restantes junto con las arandelas que fijan el soporte de montaje a la columna de dirección.
5.
Instale una arandela número WWS 120394 (3/8 de pulgada x 0.065 de pulgada de grueso), entre la columna de dirección y el soporte de montaje en cada lado de la columna de dirección, e instale los pernos
sin tuerca y las arandelas que se retiraron antes.
Apriete los pernos sin tuerca que sujetan los soportes de montaje a la columna de dirección, a 31 lbf1ft (42
N1m).
6.
Levante la columna de dirección y regrésela a su posición, e instale los cuatro pernos sin tuerca y las arandelas que fijan los soportes de montaje a la estructura de la cabina. Apriete los pernos sin tuerca a 28 lbf1ft
(38 N1m).
