Silvermine Motors Electric Power Steering System

Recommended Posts

I might just put a bungee cord on the steering shaft and pull it towards the block a bit... that should work!

The shaft needs to move about 1/2” to work. I can try a twist downwards though.. good idea.

I haven’t been back out to the shop yet, but Granny’s idea kept me awake all night. That should work actually. I reinstalled the rack without a reference mark after doing all the powder coating. It’s quite possible I have it rotated too high even for factory steering shaft angles. I hope that’s it!

In theory, the rack should not be able to rotate at all. The bushings should establish the correct position and lock the rack into place.

That said, I'm guessing there's some squirm that you could probably take advantage of and it sure does look like the angle at that bottom U-joint is off some. It's definitely different than the 240 pics you posted above.

Any chance you got the non-round side bushing in upside down or wrong somehow? Is that even possible? Here's your 280 for reference.:

The steering rack has plenty of rotation when it is all loosened from the bushings and the stop bracket. Mine is definitely rotated too far up as you can see by the different alignment angles at the knuckle on the 240 and mine.

Crisis averted, lesson learned, idiot badge earned...
Rotating the steering rack solved the issue!

Well I'm glad that it turned out to be such a non-problem, but is it really OK for there to be that much play in the rack position inside the bushing? I thought the whole point that the bushing on the right left side of the rack is NOT round is to prevent exactly that kind of rotation? What's to prevent it from rotating back to where it was before?

I guess I just never loosened mine up and collected all the tolerance in one direction...

There is a rack rotation stop on the rack. That had to be loosened of course. The two bushings have enough slack to allow the rack to rotate the 1/4” or so with no problem. Once I tightened up the rotation stop, and clamped the bushings back down there was zero movement. Plus, it is now in the correct factory position versus my “guess” after restoring the rack and re-installing it.

Plus, the not-round bushing didn’t move on the inside... the outside ROUND section of the bushing rotated under the clamp. The rotation stop was the biggest issue as I had mispositioned it.

That left side rack bushing is not round on inside nor the outside. I thought that was the whole reason it wasn't round:

Wait... Is yours actually round?

Not round but “more round” than the inside diamond shape. The bottom groove in the crossmember and the top clamp on that side are smooth and allow the rack to slip a little. The purpose of the u-clamp and the rubber stopper “lock” the position along with the upper bushing clamps.
Or that’s what I’m going with anyways..!

Well whether it was on purpose or not, it's clear there's enough squirm to move it around enough to work. Cool! Non-problem!   :beer:

In case anyone is sitting on the fence regarding picking up this kit, I added a special note to the top of the thread! PM me for details on how to save money!!

Well the spare firewall plates arrived today so I got to work! 

First a picture of the problem. The current jig puts the column down and to the right.

Next step was to carefully grind off the welds and free the collar from the plate. Then I bolted the firewall plate in, then slid the collar over the steering column. I then bolted the column into the proper position with no strain. I then slid the collar thru the firewall plate and tacked it into place with my welder.

I then pulled it all out again and ground down the ugly welding and media blasted it clean.

and because I can, I decided to powder coat the finished amended firewall plate.

Now to get this back off to @silverminemotors for making the next set of power steering firewall plates!

Wow thank you so much Mark!! We will take your sample and use it to make a new Jig to make our firewall plates. All our future customers will get the perfect angled firewall plate.
