We are currently in the process of fitting up power steering to our 1960 Jensen 541S. Obviously not an original install when rolled out of the factory in 1960 but an excellent addition to the restoration.
EZ Power Steering specialise in power steering for classic vehicles. Their main offices are in Holland where they manufacture the items but they have represntation here in the UK in
An EZ Electric Power Steering system is completely hidden underneath the dashboard. The existing steering rack or box remains unchanged and thus retains the standard steering ratio and setup. The amount of assistance is fully adjustable and is sensitive to speed and load. They use CNC laser cut bespoke brackets designed to fit the original mounting points of your car. As no holes are drilled, with no cutting or welding to the chassis or body, the car can always be converted back to its original steering column. Under the bonnet there are no changes, everything remains as original. The advantages of an electrical system opposed to a hydraulic system are numerous. The electric motor only uses power when steering assistance is necessary whilst a hydraulic pump is continuously operating when the engine is running. A hydraulic setup generally uses around 4 bhp and therefore consumes extra fuel, even when driving straight ahead.
Because the electric power steering system is truly speed sensitive, it will steer light at low speeds and not become lighter at high speed. The amount of assistance can be selected by turning a potentiometer, so that the driver can select the desired feel (i.e. more assistance with wider tires and/or a smaller sports steering wheel’. With a classic hydraulic system there is usually little feel and no possibility to adjust this at all.
In the unlikely event that the electric power steering system has a defect, the car would steer exactly like it did prior to power steering conversion. If a car fitted with an hydraulic system would have a fault the car would steer extremely heavy.
The EZ Electric Power Steering works without making a sound. It can not leak and is completely maintenance-free.
EZ Power Steering are no strangers to the Jensen 541S but ours happens to be a unique one. Unbeknown to everyone, when the new power steering system arrived is wouldn’t fit eaxctly where it needed to which left both us and them a little confused.
It turns out that the automatic transmission makes a difference to the install and only having experienced a manual Jensen they are having to rebuild the system. This means the old column and new column have been returned to Holland and we await its arrival.
