Door Hardware Lubrication Description for Isuzu S/T Isuzu - 2WD 2000

The mechanical components of the door are lubricated during assembly. If any door hardware mechanism requires additional lubrication, use Lubriplate Spray-lube A, Lubriplate Auto-Lube A or an equivalent. Lubricate the door hinge pins and the rollers at normal service intervals with 30 weight engine oil. Do not lubricate the surface of the hinge roller that contacts the hold-open link. This may prevent the roller from rolling properly.
