Inspection and Maintenance Of The Pacbrake®
With frequent use, the Pacbrake exhaust brake will operate maintenance-free. If the vehicle is used inconsistently or seasonally, it will be necessary to perform preventative maintenance. If the vehicle is exposed to excess moisture, or is used only for periodical or seasonal use, perform the following steps.
- With the engine off, using any oil-free or non-petroleum-based high-heat lubricant, spray or coat a sufficient amount on the restricter valve shaft and the attaching locations at each end of the actuation cylinder.
- With your hands or a pair of pliers, motion the valve several times to distribute the lubricant down the shaft and the attaching locations.
Note: Operation of the Pacbrake could be affected by starting the engine and idling for short periods of time. During a cold engine start-up, moisture occurs in the engine and exhaust system that creates a corrosion hazard. The brake housing may trap water in the valve shaft bore, causing a corrosion hazard. The brake housing may trap water in the valve shaft bore, causing corrosion resulting in an improper or non-functioning brake. If it is necessary to periodically start the engine, attain normal operating temperatures before shutting the engine down.
