[SEL] Diesel Engine Starter With Oil Pump

[Richard Strobel]

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.
