A. Installation of preformed packings:
(1) Identification of Preformed Packings
(a) Preformed packings are sealed in containers which are marked with the data that follows:
1 The name of the part.
2 The quantity.
3 The engine manufacturer part number.
4 The cure date.
(b) The storage life of a preformed packing is calculated from the cure date on the container.
(c) The preformed packing material is identified with the color of the material. Alternatively it can be identified from a color code marked on the outer diameter.
(2) The Lubricants Used for Preformed Packings
(a) Preformed packings are lubricated to make them easier to install. Use the correct lubricant applicable to the system into which the preformed packing is installed. Apply the lubricant in small quantities immediately before the preformed packing is installed. The specified lubricants are as follows:
1 Preformed packings in oil systemsV10-077 lubricant (engine oil)
2 Preformed packings in fuel systems liquid paraffin (Material No.V10-060) orV10-077 lubricant (engine oil)
3 Silicone rubber seals in air systems - None
4 Fluorocarbon seals in air systemsV10-077 lubricant (engine oil)
(a) Always use new preformed packings.
(b) Make sure that the storage life and condition of the preformed packings are satisfactory
(c) Make sure that the grooves and the mating faces are clean, smooth and not damaged before the preformed packing is installed.
(d) Make sure that the preformed packing is not twisted when it is installed.
(4) Do not install preformed packings to engine parts which are hot. This will cause damage to the preformed packing.
(a) Use an approved tool to install the preformed packings on to a part which has two grooves. This will prevent damage to the preformed packing.
(b) Always install the parts, that have preformed packings installed, with a straight push.This will prevent twists and subsequent damage to the preformed packing.

1 Preformed packings in oil systems
2 Preformed packings in fuel systems liquid paraffin (Material No.V10-060) or
3 Silicone rubber seals in air systems - None
4 Fluorocarbon seals in air systems
NOTE: To prevent damage to rigid seals made of material code SE/DTA or WAF used in air systems: apply a thin layer of engine lubricating oil, V10-077, to all the surfaces of the seal before it is installed.
NOTE: There are no fluocarbon seals in the Electronic Engine Control air systems.
(3) Instructions for the Installation of Preformed Packings (a) Always use new preformed packings.
(b) Make sure that the storage life and condition of the preformed packings are satisfactory
(c) Make sure that the grooves and the mating faces are clean, smooth and not damaged before the preformed packing is installed.
(d) Make sure that the preformed packing is not twisted when it is installed.
