Nissan Pathfinder Rocker Arm
The Nissan Pathfinder Rocker Arm is a lever that links the camshaft and the engine's intake and exhaust valves. The cam lobe rotates, and the Rocker Arm translates that displacement into linear motion to open and close each valve to let in air and seal combustion. The component is mounted on a fulcrum so that as the cam lobe pushes one end, the other end presses downward on the valve stem. The spring pressure of the valve returns it as the cam lobe turns away. Overhead valve designs use a pushrod to transmit motion before reaching the Rocker Arm. With overhead cam layouts, the camshaft is positioned such that it can make direct contact with the Rocker Arm or follower surface. The accurate timing of valve lift by the Rocker Arm ensures that compression is maintained, misfire is avoided, and power delivery is made as smooth as possible throughout the engine cycle of every Nissan Pathfinder. The operation of the Nissan Pathfinder valvetrain is made reliable. The geometry must be consistent, and sufficient lubrication is vital because excessive clearance or wear can cause the pushrods to bend or the Rocker Arm to break, which can all limit Nissan Pathfinder performance.

Nissan Pathfinder Rocker Arm Parts Questions & Experts Answers
- Q: How to remove and install rocker arm on Nissan Pathfinder?A:Remove the valve covers. Loosen the rocker arm shaft retaining bolts a little at a time to avoid distorting the shaft, working from the ends toward the middle of the shafts. Some of the valves will be open when you loosen the rocker arm shaft bolts and the rocker arm shafts will be under a certain amount of valve spring pressure. Therefore, the bolts must be loosened gradually. Loosening a bolt all at once near a rocker arm under spring pressure could distort the rocker arm shaft. Prior to removal, scribe or paint identifying marks on the rockers to ensure they will be installed in their original locations. Remove the bolts and lift off the rocker arm shaft assemblies one at a time. Lay them down on a nearby workbench in the same relationship to each other that they're in when installed. They must be reinstalled on the same cylinder head. Note that the shafts with the larger notches go on the intake manifold side. Check the rocker arms and shafts for abnormal wear, pits, galling, score marks and rough spots. Don't attempt to restore rocker arms by grinding the pad surfaces. Measure the outside diameter of the rocker arm shaft at each rocker arm journal. Compare the measurements to the specific rocker arm shaft outside diameter. Measure the inside diameter of each rocker arm with either an inside micrometer or a dial caliper. Compare the measurements to the specific rocker arm bore diameter. Subtract the outside diameter of each rocker arm shaft journal from the corresponding rocker arm bore diameter to compute the clearance between the rocker arm shaft and the rocker arm. Compare the measurements to the specific clearance. If any of them fall outside the specified limits, replace either the rocker arms or the shaft, or both. Installation is the reverse of the removal procedure. Tighten the rocker arm shaft retaining bolts, in several steps, to the specific torque. Work from the ends of the shafts toward the middle.
