- Application of Loctite 638
Product characteristics
- Colour : Green.
- Temperature : resistance - 55°C to + 170°C.
- TO BE USED WITH CARE : avoid any contact with eyes and skin.
!
- IF LOCTITE GETS INTO YOUR EYES, FLUSH THEM WITH WATER FOR 15 MINUTES.
- IF LOCTITE GETS ONTO YOUR SKIN, FLUSH WITH WATER AND SOAP.
Disassembly
- Disassemble the units, in the event of sticking, tap the parts to break the film.
- Remove particles of Loctite as thoroughly as possible.
Assembly
- Clean and carefully degrease surfaces using a solvent.
- Apply a single beading of Loctite 638 to one of the bearing surfaces well around the attachment
holes (thickness of beading : 1 mm max.).
- Assemble the parts and tighten screws to the required torque.
- The parts must be assembled within 10 minutes following the Loctite application.
- Possible handling after 4min - total polymerisation 6h.
Screws without adhesive drive lock or re-used after removing will be mounted with LOCTITE Frein filet SR 242.
Product characteristics
- Colour : pale blue.
- Temperature : resistance from - 55°C to + 180°C.
- TO BE USED WITH CARE : avoid any contact with eyes and skin.
!
Disassembly
- Disassemble the units, in case of lock, heat the screws.
- Clean excess material off the surface and degrease.
Assembly
- Clean and carefully degrease surfaces (the lubricant prevents polymerisation therefore making the product
ineffective) using a solvent or by washing the parts.
- Let evaporate.
- Apply on the thread, if possible at the end of the screw, only one drop of the Loctite.
- To reduce polymerisation time, spray T activator on the thread,let evaporate and then apply Loctite.
- In the case of a blind tapped hole, apply Loctite into the tapping of the hole and not on the thread of the screw.
- Assemble the parts and tighten to the required torque.
- All screws must be tightened as soon after assembly as possible.
- Possible handling after 10 min - total polymerisation 3 h.
Tightening torques
The tightening torques indicated in this manual must be respected.
A tightening torque weaker than indicated may lead to a shearing stress and may break the bolt.
A stonger tightening torque may lead to a plastic deflection of the bolt and damage of the parts.
