General Fitting Instructions: Disassembly

Observe scrupulous cleanliness when dismantling components, particularly when brake, fuel or hydraulic system parts are being worked on. A particle of dirt or a cloth fragment could cause a serious malfunction if trapped in these systems.

• Blow out all tapped holes, crevices, oilways and fluid passages with an air line. Ensure that any 'O' rings used for sealing are correctly replaced or renewed, 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).
• Wire labels on to all parts which are to be renewed, 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 renewal until after comparing it with a new part, to ensure that its correct replacement has been obtained.
