Trouble
Possible reason
See chapter,
section
1. Crankshaft does not rotate at starting attempt
a) Turning device is connected.
NOTE! Engine cannot be started when turning device is connected.
However, before starting, always check that turning device is disconnected.
03.1.1, 21.1
b) Starting air pressure too low, shut-off valve on starting air inlet pipe closed 21.1, 21.5
c) Jamming of starting valve in cylinder head 21.4
d) Jamming of starting air distributor piston 21.3
e) Jamming of blocking valve on turning device. 21.1
f) Starting air solenoid valve faulty 21.2
g) Inlet or exhaust valve jamming when open. “Negative” valve clearance (strong blowing noise). 12.
h) Starting automation on outside engine faulty 03.2, 23.
2. Crankshaft rotates but engine fails to fire
a) Too low speed (1b),
b) Automatic shut-down device is not in start position 23.
c) Load limit of control shaft or of governor is set at too low a value Fig 22-1
d) Starting fuel limiter wrongly adjusted 23.
e) Some part of fuel control mechanism jamming and prevents fuel admission 22.
f) Fuel and injection system not vented, pipe connections between injection pumps and
valves not tightened
16.3, 17.
g) Fuel filter outside the engine clogged
h) Three-way cock of fuel filter wrongly set, valve in fuel inlet pipe closed, fuel day tank
empty, fuel feed pump not started or faulty
i) Stop lever in stop position
j) Very low air and engine temperatures (preheat circulating water!) in connection with
fuel of low ignition quality
02.1
k) Fuel insufficiently preheated or precirculated 02.1 Fig 02-1
l) Too low compression pressure (1f)
3. Engine fires irregularly, some cylinders do not fire at all
a) See point 1f, 2f, g, h, k, l, 4d
b) Injection pump control rack wrongly adjusted 22.3
c) Injection pump control sleeve does not mesh properly with rack (may cause overspeed
if set in direction towards increased fuel quantity)
16.5
d) Injection pump faulty (plunger or tappet sticking; delivery valve spring broken, delivery
valve sticking, constant pressure relief valve leaking)
