Wedge Power Steering flush & Prime [TR8]

[GBRandy]

My new power steering rack & pump are installed. I now need to flush and prime the system according to the notes that came with the rack.

What it fails to do is tell me how, exactly, to do that.

Based on my review of the now 30 year old ROM, I need to connect the system up and fill it. Turn the engine by hand for awhile and fire it up. That does not sound like a "flush" to me.

What is the best method to take this system from dry to filled and operational?

Thanks!

I do not have any experience with a TR8 but have done the following on my Honda. Fill with fluid and with engine on turn steering back and forth several times which will force air out. If you want to flush system you can disconnect low pressure hose and connect it to a containner. While engine is running add more fluid to replace fluid flushed from low pressure side. Doing it myself, I run engine for a short interval, stop engine and replenish fluid, making sure that reservoir does not empty.

page 167 in the service manual says,,,,,POWER STEERING SYSTEM
Bleed 57.15.02
T h e h y d raulic steering system is
self-bleeding but care must be taken to
ensure that at no time is the fluid reservoir
allowed to empty or become dangerously
low.
This is especially important where both the
pump and the rack have been newly
installed. When the hydraulic system has
been disturbed, proceed as follows:
1 Ensure that all the hydraulic pipe
connections are tight.
2 Fill the hydraulic fluid reservoir to the
correct level, indicated on dipstick,
with one of the recommended fluids.
3 Place the road wheels in the
straight-ahead position.
4 With the drive belt slackened or
removed, rotate the pulley by handto
prime the system.
5 Fit and adjust the drive belt, see
57.20.02.
6 Check, and top up the fluid reservoir
as necessary.
7 Start the engine and allow it to idle.
8 Turn the steering-wheel to full lock
and return to the straight-ahead
position.
9 Check and top up the hydraulic fluid
reservoir.
10 Turn the steering-wheel to the
opposite lock and return to the
straight-ahead position.
11 Check and top up the hydraulic fluid
re servoir.
12 Turn the road wheels from lock to
lock several times to permit air to be
fully exhausted from the system.
13 Return the road wheels to the
straight-ahead position and check the
fluid level in the hydraulic reservoir.
N O T E : R epeated turning o f the
steering-wheel when the car is stationary
will not harm the steering mechanism and
hydraulic units, but will affect the
mechanical components of the steering and
tyre threads. Whente sting or bleeding the
power steering, to minimize tyre scrub the
road wheels should be rotated slowly or
the front wheels positioned on steering
