14A-6 Service Information Guide (All models) Recommended liquid gasket 1. Using the thread liquid gasket Caution Make sure to use a liquid gasket with the above product name or equivalent. Use an appropriate amount of liquid gasket. Follow the handling precautions for the product. Do not use Loctite 515/518 or FMD 127 (Loctite 5127), as they are anaerobic, and do not provide sufficient effect when there is a gap larger than 0.25 mm {0.0098 in} between the contact surfaces of metals. Caution Be careful to apply a proper amount of the liquid gasket to avoid an excess or lack in application. Be sure to overlap the beginning and ending of the liquid gasket application.

Be careful not to misalign the applied part with the mating part when assembling. Note When there is a misalignment, apply again. Use the same size studs as a guide when using with a section which has no positioning such as a knock pin. Whenever disassembling, completely remove old liquid gasket using a scraper, and clean by removing any oil, moisture, filth, etc. from the locations of parts and the mating parts where liquid gasket was used by using a rag, etc. After cleaning, apply the specified liquid gasket to each location and assemble them. Caution After applying the liquid gasket, assemble within 15 minutes.

Note When more than 15 minutes have passed after applying liquid gasket, remove the liquid gasket and apply it again. Note It is better to start the removal operation approximately 10 minutes after applying when using gasket remover to make the operation easier while cleaning. Caution Wait at least 30 minutes before starting the engine after assembling each part. Caution Do not apply gasket remover to plastic parts and painted parts. Apply liquid gasket of the specified bead width to one side of the contact surface thoroughly.
