3.5 ENGINE SPEED ADJUSTMENT
A mechanical governor controls the engine speed.
The governor is built into the fuel injection pump. All
governors are adjusted to the rated speed at
nameplate power or maximum allowed pump load
before leaving Clarke. During Start-Up Inspection or

minor speed adjustment may be required. It is
recommended that this adjustment be performed by
the authorized Service Dealer representative.

Engine” Procedure in this manual.
B. Let the engine warm-up. Loosen the jam
nut(s) (Figure #38).
C. While observing the instrument panel tach
