How To Add Power Steering To a 1949 Packard
Posted by Packard 1948 On 2015/9/22 15:02:15
Here are the pictures of the Power Steering system I added to my dad's 1949 Series 22.
The actuator is a Monroe actuator from a 1955 Packard.
I had to use the 1955 Packard Pitman arm because it has a curve in it to allow the two PS hoses to be installed in the actuator without conflict.
I also had to use two drivers side steering tubes (the parts that connect the actuator to the tie rod ends) because the passenger side tube needed a little bit of a curve in the tube so that it did not conflict with the actuator bracket I fabricated).
I had to fabricate a passenger side actuator to frame anchor bracket. My first attempt was to use a 1955 OEM bracket however the chassis are different and the OEM part had a curve in it so that it when installed it to the Series 22 chassis it did not match the rubber grommets that the actuator uses to attach to the anchor.
Naturally hydraulic hoses had to me custom made for this application.
A 1952 Chrysler PS pump is a cleaver contraption because it is a generator with a PS pump mounted to the back of the same shaft. I thought this would be an elegant solution because I could install it in lieu of the existing generator (had to fabricate a heavy duty bracket for it). All I needed to do was to use a pulley that matches the Packard V belt thickness pulley and a slightly longer belt.
The remote oil filter still worked and all I needed to do was to install it a bit higher in its bracket and bend the steel oil lines slightly to make it work.
The Chrysler pump when installed was in conflict with the OEM battery (the long and skinny 6V battery) so I had to redo the OEM battery box to accommodate a 6V "Type 4" which is not as long as the OEM battery but much wider (from a golf cart) battery. This ended up actually being a good thing because the Type 4 battery has about 150 more cold cranking amps than the OEM battery.
The Chrysler pump used in the same system with the Monroe actuator in hind sight was a bad choice because the output (pressure and flow) of the Chrysler pump is a perfect match for the Bendix actuator (both are 650 PSI and 1.5 GPM) however the Monroe actuator apparently needs more pressure and flow (1000 PSI and 1.9 GPM). Those who also visit the V8 pages of this forum will know of all of my trials and tribulations trying to figure this out. The Monroe seemed to be a better choice at first because it has much less external rubber hoses and valves but either I should have gone with the Bendix or else used a separate PS pump but then it would have been a huge hassle dealing with different brackets and belts.
Since the Chrysler pump is a lower output design as compared to the needs of the Monroe actuator, the PS system makes an annoying humming sound at very low speed turns such as in parking when you really need the power assist. Cant hear it from outside the car but inside it is annoying. I told my dad to turn up the radio to fix it. He is REALLY happy to have PS...noisy or not.
I did modify the Chrysler pump to put out more PSI (now puts out 1000 PSI) by adding shims ( 3 washers) to the pressure relief spring however now I need to figure out how to shim up the flow control valve to increase the GPM output.
Anyhoo...as my Hot Rodding mentor says "Well...that's hot roddin"
