General Fitting Instructions: Dismantling

Be as clean as possible when dismantling components, particularly brake or air conditioning system parts. A particle of dirt or a cloth fragment could cause a serious malfunction if trapped in these systems.

• Blow out all tapped holes, crevices, oil ways, and fluid passages with an air line. Make sure that any O-rings used for sealing are replaced if disturbed during the process.
• Use marking ink to identify mating parts and ensure correct reassembly. Do not use a center punch or scriber to mark parts, they could initiate cracks or distortion in marked components.
• Wire together mating parts where necessary to prevent accidental interchange (e.g. roller bearing components).
• Attach labels to all parts which are to be replaced, and to parts requiring further inspection before being passed for reassembly; place these parts in separate containers from those containing parts for rebuild.
• Do not discard a part due for replacement until after comparing it with a new part, to make sure that its correct replacement has been obtained.
