[SEL] Diesel Engine Starter With Oil Pump

[Howard Bottles]

On my JD 730D I push down on the decomp pedal, crank the engine until
the oil pressure comes up, then relase the decomp pedal and let it crank
3-4 revs on full comp w/o fuel to heat the cylinders, the put some
throttle on it and she lights right off

Francis;
  I remember the compression release lever was close to the pony
motor..should have mentioned that is opened prior to cranking..believe
it keeps the exhaust valves open.  It may have also shut the injectors
down..never thought about it until now.  His was a '57..can't remember
now how the engine was shut down..had to shut the fuel off somehow..on
his newer grader one just pulls up hard on the foot throttle.


It may have been an add-on but believe some turbo charged engines had an
accumulator that would release oil to the turbo bearing after the engine
was shut off.


Well catcha later,
RickinMt.
