Now we study about "CUMMINS" engine
2) Faults:- Engine misfiring.
Probable causes and Remidial actions.
A) Dirty fuel filter.
Check fuel filters and If necessary:-
a) Change fuel filter.
b) Change fuel filter elements.
c) Clean the inlet filter.
B) No /Less fuel in tank.
a) Change fuel filter.
b) Change fuel filter elements.
c) Clean the inlet filter.
B) No /Less fuel in tank.
Filled fuel in the Tank. Bleed air from fuel system in the following steps:-
a) Loosen the bleed plug on the fuel filter and operate the priming pump until the fuel emerges of bubbles. Tighten the bleed plug.
b) Then loosen banjo plug on injection pump and operate priming pump until fuel emerges free of bubbles. Tighten the banjo plug.

D) Deffective injector.
Remove the defective injectors and Get it overhauled/calibrated or replace with new one.

E) Valve clearance is not proper.
To check Valve clearance, and adjust the clearance follow these steps:-
a) Un-screw bolts and remove cylinder cover.
b) Crank engine until the inlet valve closed then turn approx (1/2) half turn further.
c) The feeler gauge should pass between the valve cone end and the rocker lever with suction.
d) If the valve clearance need resetting loosen lock nut and readjust by means of the set screw.
e) Tighten lock nut and recheck valve clearances.
f) Renew gasket, sealing ring and fit cylinder head cover.
