Fluid Rell
The following
recommendations are
for general purpose steering systems
(both TRW and Sheppard).
• For normal temperatures, use
Automatic Transmission Fluid
(ATF) Type E or F or Dexron® III.
• For cold temperatures of -22º F
(-30º C) and above use ATF Type
A.
• For extremely cold temperatures
between -22º F (-30º C) and -40º
F (-40º C) use ATF Type B.
Inspection
NOTE
Before removing
reservoir cover, wipe
outside of cover so that no dirt can fall
into the reservoir.
1. Check the
uid level; add uid if
required.
2. Check uid
for contamination,
discoloration, or burnt smell;
correct source of such problems
before replacing uid and lter.
When adding uid, be sure to use uid
of the same type. While many u
-
ids have the same description and in-
tended purpose, they should not be
mixed due to incompatible additives.
Mixing incompatible uids may lead to
equipment damage.
CAUTION
If incompatible (insoluble) uids are
mixed in a power steering system,
air bubbles can be produced at the
interface of the two uids. This can
cause cavitation, which reduces the
lubrication between moving parts in
the gear. This could result in worn
components.
The mixture
of two different uids,
although harmless to individual
internal components, may initiate a
chemical reaction that produces a new
compound that will attack seals and
other internal components.
Do not
mix different uids.
