FUEL INJECTION PUMP--GENERAL
INFORMATION
Most engines are equipped with a Stanadyne or Lucas
rotary-type injection pump. Rotary injection pumps are
dynamically timed at the producing factory and reference
timing marks are accurately stamped on front plate and
injection pump hub. Timing can be checked and adjusted
as covered below using theTIME TRAC Kit.
Higher horsepower engines use multiple-plunger, in-line
type Nippondenso fuel injection pump with a mechanical
flyweight governor and aneroid control.
In-line injection pumps are statically timed by locking
engine at No.1 TDC compression and installing pump with
injection pump drive hub lock-pinned (refer to Group 35,
INSTALL IN-LINE INJECTION PUMP and/or IN-LINE
FUEL INJECTION PUMP TIMING).
TIME TRAC is a registered trademark of Stanadyne Automative Corp.
