Rocker Arm Shaft

Truck Bus Heavy-Duty Rocker Arm Bracket Assembly MAN Engine:V8 Steel Forged Displacement:11-13L Roller rockers can also be used in overhead cam engines. However, these generally have the roller at the point where the cam lobe contacts the rocker, rather than at the point where the rocker contacts the valve stem. Friction may be reduced at the point of contact with the valve stem by a roller tip. Compatible Vehicle: MAN Engine:V8 Displacement:15L OE No.:51.04202-0144 51.04201

Truck Bus Heavy-Duty Shaft Mounted Rocker Arm Bracket Assembly Engine:X6110 Steel Forged Mass-produced car engines traditionally used a stamped steel construction for the rocker arms, due to the lower cost of production. OE Replacement : Meets OE standard quality and performance requirements. Utilizes the latest in design and material technology Produced under strictly observed quality under international standards Advanced manufacturing technology ensures durability and

Truck Bus Heavy-Duty Shaft Mounted Rocker Arm Bracket Assembly Engine:4NC2A Steel Forged Rocker arms contribute to the reciprocating weight of the valvetrain, which can become problematic at higher engine speeds (RPM). For this reason, aluminum is often in engines that operate at higher RPM. Upgraded bearings for the rocker arm's fulcrum are also sometimes used in engines operating at high RPM.

Truck Bus Heavy-Duty Valve Rocker Arm Rockshaft MAN Engine:D08 Steel Forged Displacement:5-73L The top of the pushrod presses upwards on one side of the rocker arm (located at the top of the engine), which causes the rocker arm to rotate. This rotation causes the other end of the rocker arm to press downwards on the top of the valve, which opens the valve by moving it downwards. Compatible Vehicle: MAN Engine:D20 D26 Displacement:11-13L OE No.:51.04203-5064 Material:: Steel

Truck Bus Heavy-Duty Valve Rocker Arm Shaft Assembly MAN Engine:V8 Stamped Steel Forged Displacement:15L A roller rocker is a rocker arm that uses needle bearings (or a single bearing ball in older engines) at the contact point between the rocker and the valve, instead of metal sliding on metal. This reduces friction, uneven wear and "bell-mouthing" of the valve guide Compatible Vehicle: MAN Engine:V8 Displacement:15L OE No.:51.04203-0090 Material:: Steel Application: Truck,

Truck Bus Heavy-Duty Valve Rocker Arm Shaft Assembly MAN Engine:V8 Stamped Steel Forged Displacement:15L Rocker arms in automobiles are typically made from stamped steel, or aluminum in higher-revving applications. Some rocker arms (called roller rockers) include a bearing at the contact point, to reduce wear and friction at the contact point. Compatible Vehicle: MAN Engine:V8 Displacement:15L OE No.:51.04203-0089 Material:: Steel Application: Truck, Bus OE Replacement: OE
