• | J 8062 Valve Spring Compressor |
• | J 43105 Valve Stem Seal Installer |
Important:
• Never shim the spring to obtain an installed height under the specified
amount. • Install the valve spring seat shims under the rotator, between the rotator
and the cylinder head spring seat. • Add a maximum of one valve spring seat shim, up to 0.726 mm (0.030 in)
thick to achieve the valve spring installed height specification. • The combination of valve spring seat shims to correct valve spring installed
height and valve spring tension should not exceed 1.524 mm (0.060 in)
thick.
Caution: Wear safety glasses in order to avoid eye damage.
Caution: Compressed valve springs have high tension against the valve spring compressor. Valve springs that are not properly compressed by or released from the valve spring compressor can be ejected from the valve spring compressor with intense force. Use care when compressing or releasing the valve spring with the valve spring compressor and when removing or installing the valve stem keys. Failing to use care may cause personal injury.
Important: When installing valve stem oil seals onto the valve guides, be careful not to tear the seal lip.
Important: When installing valve seals, J 43105 must be used to achieve correct installation. Failure to use J 43105 may cause excessive oil consumption.
Important: When installing valve springs, the small end of the valve spring must be installed up.
• | Use grease to hold the keys in place. |
• | Ensure that the keys seat properly in the upper groove of the valve stem. |
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.
