Title: Gamma power steering Post by: Roland on 30 June, 2014, 12:33:41 PM Has anyone tried modifying the standard camshaft driven type by using one of the electric motors from an after market electric steering system ? If so, what were the results?
Title: Re: Gamma power steering Post by: lancialulu on 30 June, 2014, 12:41:43 PM I know this has been discussed within Gamma circles but have not heard if anyone has tried to direct couple the steering shaft - unless you are talking about replacing the pump with an electric pump???
Personally I just keep the belts slack.... Title: Re: Gamma power steering Post by: Roland on 15 July, 2014, 03:59:11 PM Yes, just replacing the steering pump with an aftermarket electric one.

I'm am so out of touch with how cars are screwed together these days. Next you'll be telling me they have a robot shouting navigation instructions at you as it reads an out of date map from a digital versatile disk.

The input shaft has to be in the right place so that the body of the rack is centred in the car, if it's not you'll have a bigger turning circle one way than the other! The length of the rack between knuckles has to be the same as does the steering arm otherwise you'll end up with some really unwanted wheel deflections as the suspension rises and falls, mounting it in any other position than original will also induce bump steer.
If you really need to change the power steering set up the electric pump has to be the most flexible option? An electric column would be the second choice but is going to be a lot more complex and you'll probably end up with a girly button on the dash too.... Please also consider telling your insurance company about any modification to the steering! If you don't any subsequent claims could be voided.

I wasn't sure if it was with encouragement or discouragement but to me it would be an essential first step with these sorts of ideas. There's a lot to get wrong. David |
