How should the rocker shaft and rocker arms be inspected and maintained on BMW 2002?

Scrub the rocker shaft and with it roll it on plate glass; rarely it may be bent and if present it is advisable to acquire new ones. Make sure that the surface of the shaft is smooth each of the rocker arms does not leave any worn ring ,and replace the shafts if they are worn. Check the rocker arms for wear on the rocker bushes, on the face that rock against the stem of the valve and of the faces which ride on the Rocker shaft. To determine whether the rocker arm bush is worn, the rocker arm tip should be held and placed on the shaft and rocked while being observed for lateral shake. In case, both shake is present and the arm is loose on the shaft, then a new bush or the rocker arm should be fitted. Also it is required to check the condition of the roller connecting with the end of the valve stem and the slide pads coming into contact with the cam lobes and replace them if worn out.

BMW 2002 Rocker Arm

The BMW 2002 Rocker Arm is the critical lever that converts camshaft rotation into straight line valve movement, allowing the engine to breathe on cue. Acting like a seesaw between the cam lobe and valve, the Rocker Arm takes the spin of the cam and the straight push of opening each port, which is closed by a spring. Within the 2002 range, two valve-train layouts influenced the Rocker Arm form: early overhead valve pushrod systems and later overhead cam heads. Pushrod versions placed the Rocker Arm atop the head, which was driven by a rod from the block, normally as economical stamped steel pieces, although roller tipped and full roller styles were introduced later, giving the arms additional bearings for the Rocker Arm to slash friction and unlock extra revs. Overhead cam models applied shorter, center pivot or finger follower units directly under the lobes and eliminated the use of pushrods, reduced weight, and maintained the same principle of motion transfer. Worn tips or pivots on these levers could be the cause if a BMW 2002 should develop ticking or sluggish acceleration. Consistent lubrication makes each BMW Rocker Arm quiet and efficient.
