Rock-AssaultTM
Steering Pump Kit
The stock Toyota
pump is just barley able to supply the
volume and pressure needed to run Hydraulic
assist steering. The stock pump puts out
1,300 psi @ one gallon per minute. The stock
pump is not able to provide enough fluid to
run both the stock steering and the demands
of a ram, especially at low RPM's. Drilling
out the restrictor plates in a stock pump
for more volume often leads to pump failure.
The answer is a
replacement "TC" style pump. The Trail-Gear
Rock-AssaultTM
pump puts out 1,600 psi of pressure at 4
gallons per minute. This provides the full
fluid volume your steering box and ram are
looking for, even at an idle.
Pump kit
includes pump, pump bracket, reservoir,
reservoir bracket, belt, fittings
hoses, & hardware. Pump kit is designed
to work with stock or ram drilled IFS power
steering boxes.
Application
Notes: This pump and bracket is designed to
fit all Toyota 4cyl 4wd motors from 1979 -
1995. A large power steering fluid cooler
(included) is
required on the low pressure side of the
system. Pump bracket works in conjunction with
stock idler bracket. If your truck is not
currently equipped with power steering, you
will need to purchase the idler bracket and
replace the steering gear box with one
designed for use with power steering. The
stock fan belt will not work with this pump
and will need to be replaced with Napa #
9440 belt. Belt is included with kit.

Reservoir & Bracket
When installing
a high flow pump such as the one listed
above, it is important to use a larger
reservoir to provide enough fluid when the
system needs it. The sock reservoir is fine
for the stock pump but is not adequate for
the TC style aftermarket pumps. Side input
of reservoir is a #6 JIC fitting and
the bottom outlet to pump is a #10 JIC
fitting. Reservoir includes cap.
Reservoir
bracket makes it easy to bolt in the
reservoir on most 4cyl 4X4 Toyota
applications from 1979 - 1995. Includes
mounting hardware. Unpainted
finish.

Steering
Fluid Cooler
If
your running a high volume/pressure pump
your system is generating much more heat
then the stock system. Fluid overheating can
cause damage to steering pump and steering
box. Installing a oil cooler in front of the
radiator is the best way to prevent this
over heating. Our cooler features a fin area
of 9" X 8" and does a great job of keeping
the steering fluid temps under control in
all conditions. Mounting kit sold
separately.
