GENERAL INFORMATION
Cautions:
1. Always use the above brandnames or an equivalent as the sealant.
2. Since Loctite FMD127 and Three-Bond 1386 are anaerobic, do not use them in case a gap exceeding
0.25 mm is occurring between the metallic mating surfaces since satisfactory effects cannot be
expected.
3. Always use the optimum quantity of sealant. Observe the handling precautions designated for
respective products.
When applying a sealant :
(1) when applying a sealant over a surface where some other liquid gasket was used previously, thor-
oughly clean the reside sealant using a scraper and wipe the surface by waste cloth to remove oil,
moisture, dust, etc. from the surface.
(2) When using the gasket remover “Bundo 391D” made by Three-Bond (Isuzu’s Part No. 1-8840-0542-0)
to facilitate the “cleaning work”, apply the remover and leave it as is for “about 10 minutes” before
starting the removal work.
(3) Be careful not to apply too much or too little.
(4) How to use the TB1207C and TB1207B
Apply them with a line diameter of 3 mm or more and for a thickness of 1 ~ 2 mm.
Apply them along the gluing groove without interruptions and assemble the mating structures with 5
minutes.
Also, after finishing the assembly, leave the assembly as is for at least 2 hours and do not run the
engine during this period.
