Isuzu Industrial Diesel Engine A-4LE2 BV-4LE2 MODEL Service Repair Manual
- 1. Each time you disassemble parts that use liquid gasket, completely remove the old gasket residue from each of the parts and matching sections using a scraper, then clean each of the parts to completely remove oil, water, and dirt etc. from the various surfaces by a cloth. Using the specified type of liquid gasket, apply new liquid gasket to each of the surfaces before reassembling the parts.
- 2. In order to make it easier to clean liquid gasket surfaces, apply gasket remover liquid (Pando- 391D made by ThreeBond Co., Ltd.) and leave the part to stand for approximately 10 minutes, after which the old liquid gasket residue will be easier to remove. However, this should not be used on resin components or painted components.
- 3. Please take care not to apply too much or too little liquid gasket. Also, you should always re-apply the liquid gasket upon itself when you start and finish application.
- 4. Make sure that there are no gaps when reinstalling the liquid gasket parts to each other. If there are gaps between the two parts, re-apply the liquid gasket. Some parts, especially the oil pan, use the same size studs as a guide to eliminate the need for knock pin positioning etc.
- 5. Re-install these parts within 5 minutes of applying the liquid gasket. If more than 5 minutes passes, remove the previous liquid gasket and re-apply it. 6. Please wait for at least 30 minutes since the last part is installed before starting the engine.
