GENERAL INFORMATION
SCOPE
NOTE
A Service Life Extension Program (SLEP) has been implemented on selected D7F Tractors. This revised man-
ual is designed to help you perform lubrication, troubleshooting and maintenance on both configuration D7F
Tractors.
The major differences between a non-SLEP and SLEP tractor are as follows:
a.
A non-SLEP tractor is equipped with either a Model D333 or early Model 3306 engine. These
engines use glow plugs for cold weather starting. In addition, there is no oil sampling valve for
engine oil sampling.
b.
A SLEP tractor is equipped with a later Model 3306 engine, with an ether staring aid system
and an engine oil sampling valve. Some SLEP tractors may be equipped with a transmission
oil sampling valve.
Refer to WP 0002 00, Equipment Description and Data, for further information on how to verify which tractor
you have.
