Removal Procedure
Tools Required
• | J 38042
Dual
O-Ring Joint Separator |
• | J 39500-B
A/C
Refrigerant Recovery, Recycling, and Recharging (ACR4) System |
- Recover the refrigerant. Refer to Refrigerant Recovery and Recharging
.
- Place the
J 38042
on the refrigerant line directly behind
the female nut of the dual O-ring joint.
Hold pressure against the nut.
- Loosen the female nut until the seal of the dual O-ring joint
is broken. This procedure aids in the seal separation.
- After the seal is broken, slightly tighten the female nut to
facilitate the
J 38042
removal.
- Remove the female nut. Separate the connection.
- Use a non-metallic tool
to remove the O-rings.
The use of a non-metallic tool minimizes the chance of impairing the
seal surfaces.
- Inspect the line for kinks and dents.
- Inspect the connection for the burrs and nicks.
Installation Procedure
Tools Required
J 39400
Electronic
Halogen Leak Detector
- Lubricate the O-rings
using 525 oil or mineral oil before installation.
- Install the O-rings.
- Oil the bore using a small amount of refrigerant oil before assembly.
- Align the end forms for pilot-to-bore insertion.
- Push the pilot and the bore together completely.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the female
nut.
Tighten
Tighten the nut to 24 N·m (18 lb ft).
- Recharge the A/C system. Refer to Refrigerant Recovery and Recharging
.
- Leak test the system. Refer to Leak Testing
.
