description

This 7E-6814 is dedicated valve camshaft for single cylinder bank of 35 series engine. Its lobe lift and duration are factory calibrated. It drives valve tappets to control valve opening and closing timing. Forged alloy steel blank with deep high-frequency hardened and mirror finished cam lobes, stable under high temperature and cyclic impact load. It is widely used on mining, marine and generator engines, normally replaced with cam bearings, thrust washers and tappets during overhaul.

FAQ 

Q1：Can 7E-6814 be interchanged with 7E-5539 camshaft?
A：No. Lobe layout, lift parameter and locating structure are different, not compatible.

Q2：Must the camshaft on the other bank be replaced at the same time?
A：Not mandatory. Inspect the other camshaft separately and replace it if worn severely.

Q3：What typical faults will a worn camshaft cause?
A：Valve train noise, low power on single bank, unbalanced exhaust temperature, high fuel consumption and rough idle.

Q4：Can old cam bearings be reused with the new camshaft?
A：Not recommended. Bearings and journals are mating friction pairs, better to replace together.
