Note: The installation of the compression brake must be completed prior to adjusting the valve lash, the injector lash, or the compression brake's slave piston lash.
Place the compression brake over the taperlock studs and onto the engine.
Install the hard washers and four bolts 1, 2, 3 and 4 through the engine brake housing group. Finger tighten the bolts.
Install the hard washer and nut 5. Finger tighten the nut. Note: Use the torque sequence that is shown in Illustration 1.
Tighten four bolts to 50 7 N m (37 5 lb ft). Turn the bolts through an additional 90 5 degrees.
Tighten the nut to 50 7 N m (37 5 lb ft). Turn the nut through an additional 90 5 degrees.

Before the compression brake's slave piston is allowed to contact the bottom of the housing bore, the free running torque of slave piston adjustment screws (1) must not exceed the following value. ... 3 N m (27 lb in) (2) Final torque for two full nuts ... 34 5 N m (25 4 lb ft) (3) Final torque for three taperlock studs ... 65 10 N m (48 7 lb ft) (4) Final torque for the solenoid ... 20 N m (15 lb ft)Slave Piston Lash Settings
Note: Refer to Testing and Adjusting, "Slave Piston Lash - Adjust" for the complete procedure for adjusting the slave piston lash.
Prior to adjusting the lash setting for the engine compression brake, check the identification plate that is on the compression brake's casting in order to determine the model that is installed on your engine. You must have this model number and the engine's serial number prefix in order to determine the lash setting for your engine.

(1) Check the identification plate that is on the compression brake's casting in order to determine the model that is installed on your engine.Note: The slave piston lash setting is specific to the model number of the compression brake and to the serial number prefix of the engine. Use these settings only for the compression brakes and the serial number prefixes that are specified in the table.Pacbrake Compression Brake
Note: There is a fastener group that utilizes 12 point bolts for the installation of the compression brake to the cylinder head. If your compression brakes utilize 12 point bolts, refer to Specifications, "Compression Brake" for this type of fastener group.Installation Information for Fastener Group That Uses Hex Head Bolts
