Power steering electrically assited

Thought I might chime in as I have been working on installing electrically assited power steering into My RF.
This is all as a result of Peter McKluskeys decrepit age an shoulder injury and my selfish need to insure he continues to be my wing man on the occasional drive into the country.

Anyway I found my self searching for a method of keeping the old bastard in his GT40 and will help him install the same unit to his DRB.

I used the column from a Holden Barina / Opel Corsa 2002 < 2004, and sourced the controller from (www.rallywiz.com - Electronic Power Steering Controllers - Opel Corsa Electric Power Steering EPS units, Escort power steering, electric power steering, Nova power steering kit, power steering column, electric steering column. suzuki wagon R power st) it is designed to work together with the factory ECU fitted to the column. I understand it replace the need for sensor feedback used in standard vehicles using this column and gives the abilty to vairiabley control the power assit.

The installation was relatively simple no modifications to the chassis. all the same mounting points have been used. The original steering column mounting bracket from the factory column is removed with a cutting disk transplanted onto the new column and I even have height ajust.

The rear bracket of the factory column is removed by drilling out the rivets and remounted to the chassis in its original position. I fabricated two torsion bars which mount off the new columns original cast aluminium housing down to the original bracket remounted to the Chassis using 8mm grade 12 socket head bolts & nuts at each end.

Had to remove steel mounting bracket at the front of the new column to allow the original columns bracket to be welded in place, also removed the steering lock and miscellaneous brackets. A brass bush is installed at the front on the column to support the bearing and sleeved over the housing just behind the bearing.

I modified the Intermediate uni's and shaft and reconnected the column to the rack and Bob's your uncle.

To be honest I haven't wired up the unit yet and have to source a steering boss to suite the new column but dont expect that to be difficult.

I can now use a steering quickner to change the steering ratio and hopefully will be able to use the 40 comfortabley in traffic and so will Pete even with his doggy shoulder.

I will post photos as soon as i can.

As a side note Jim C who is always happy to advise suggested when dealing with steering components to check the regs relating to modifiying original components, to have any welds crack tested and certified. He's not actually a bad bloke for a Kiwi.

Forgot to mention the cost: New second hand column $160 + $85 in miscallaneous parts and of course my labour $5000

I thought it was interesting, Mick. The US 40 owners, and many others, seem to be obsessed with accuracy - instruments, grommetted seats, rear vision mirrors, RH gear change, etc., so may not like power steering. The RF40 is fairly accurate too, of course, but cars like the DRB (such as old Pete has) are modernised for various reasons. I think power brakes (I know, sacrilege), centre gear change, and a few other things like air conditioning make the cars more user friendly if you want to get in and drive it every day. Power steering as an option is a good idea. So are wind down windows, as covered in a recent thread on here, if you want them. There is a european company makes EZ electric power steering, fitted to old classics like Aston Martins, Jaguars, even early 911's, to make them more enjoyable for their wealthy but geriatric owners, or even wifey. The assist on these is speed variable, or can be programmed via GPS without hooking up to the speedo, I believe. But much more pricey than your set-up, just to get a kit.

Mick, are these right hand drive only units ?? My car is LHD.

Dalton, do you have a website for the aftermarket unit you are talking about ??

Just Googled it, is this the one EZ Electric Power Steering

Inquiring minds want to know.

Hi

In the 40 I am building for my lady I am fitting power steering as she finds driving my 40 a bit too heavy at slower speeds or tight corners.

This is a photo of the power rack I have fitted in her 40.

Hi Dimi,

what was the rack type you used? looks good the route i took was the same as the Rally builders are taking on the content. They are installing electrically operated columns to reduce the risk of failure or addition power loss & weight.

Mick
 
Brian the column is suitable for left or right hand drive applications I post a couple of photos for you shortly. Had a look at the EZ site the column i used is exactly the same as the column type for small vehicles.

Hi Mick

The rack came out of a 96 Toyota Spacia/Townace van and required no modification as the width is perfect for the DRB with corvette front suspension and fits the Corvette rod ends.

I prefer the hydraulically operated rack due to the fact that the rack works as long as the engine is running.

With electrically operated racks there is always the risk that if power fails, blown fuse or bad connection, there is no assist and usually always at the worst time.

Dimi
 
Brian, yes, that's the web site for the EZ steering I was talking about. In Sydney here, Cummins Classic Cars are agents.

I believe Iain (Straight Eight Racing, on this site) fitted power steering (not EZ) to his racing RF40, so he may have comments on alternatives he found and how successful his steering has been.
 
Andy Green has details and pictures of fitting a similar electric power steering column in his Tornado in his build log - Norfolk Tornado.

Kiwi, what rumours are you starting Mick, I was only joking about the sheep fetish.

all the best ,dont hook the polarity up back to front on that power steer.

I will be interested with the outcome on this project.

Darren,
I believe that Mick got all his ideas from me, after I’d posted it photos & descriptions in my build log.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o:p></o:p>
Mick,<o:p></o:p>
I’ll be interested in your feedback on what its like to drive with the system enabled, mines still a few years off from being driven<o:p></o:p>
Dimi,<o:p></o:p>
An electrical power steering system is as reliable as a hydraulic system; otherwise they wouldn’t be as common place as they are. Correctly rated fuses rating and good electrical connections will be longer term more reliable that pumps & O-ring seals. For me there real advantage is that you don’t have a hydraulic pump & lines to mount, and a standard rack is utilised<o:p></o:p>

I have been in the trade for 35 years and I dont know anyone who has changed an electric column or had issues , replacing hydraulic components in a weekly event in my shop.

If the electric fails you end up with normal steer as the column is 1:1 the motor just helps drive the column .On hydraulic it will get real heavy because the ratio is different in the rack.

Andy your right you did give me the idea my memory isnt what it used to be very selective recall, mostly when the ex asked what I spent $200 dollars on i took out of the auto teller the night before. They where the days.
 
Hey Jim the controler I received from rallywiz came with what i hope are correct instructions. I will be doing a test run next weekend. fingers crossed. I will hound sh*t out of you before hand as usual.

Mick
 
Couple of pics of the power steering column installed. The variable control is to the RH side of the steering wheel easily accessible. very simple install hope like hell it works.

What size shoe will fit between the floor and the bottom of the steering power jobbie and stuff. Just looks a bit tight on toe room for my size 11 boats!

Ian
 
The pedal height would be about the top of your shoe Ian my foot is 8.5 and the heel is of the floor, however the end bracket on the column can be raised or lowered to suite. It looks lower than it is.

Mick ya Bastard I just caught up with this post, I had my wheel chair getting a V8 put in it, the V6 doesn't get the adrenalin going these days.
Looks pretty cool mate, and I really appreciate your concern for an old blokes rooted shoulder. If the steering works I'll be able to drop the tire pressures and pick up about three seconds around the paper clip I reckon.
Remember to give me a call if you want a hand or even someone to pass the beer.
And cut out the Old ya bastard:furious:
