OIL PUMP PRESSURE
The MINIMUM oil pump pressure is 41.4 kPa (6
psi) at curb idle. The MAXIMUM oil pump pressure
is 207-552 kPa (30-80 psi) at 3,000 RPM or more.
CAUTION: If oil pressure is ZERO at curb idle, DO
NOT run engine at 3,000 RPM.
PISTON AND CONNECTING ROD ASSEMBLY
The pistons are elliptically turned so that the
diameter at the pin boss is less than its diameter
across the thrust face. This allows for expansion
under normal operating conditions. Under operating
temperatures, expansion forces the pin bosses away
from each other, causing the piston to assume a more
nearly round shape.

SPECIAL TOOLS
5.9L ENGINE 124
All pistons are machined to the same weight,
regardless of size, to maintain piston balance.
The piston pin rotates in the piston only and is
retained by the press interference fit of the piston
pin in the connecting rod.
