vega steering box stiff to rotate
While I had my '29 Model A up in the air and Vega steering box disconnected from everything I noticed an issue.
The steering wheel would obviously rotate very easily BUT there was a point when the box was mid-way beteen locks that it stiffened up. It wasnt massivly stiff but it stopped and required a little pressure to encourage it though the point and it then loosened back up again. It did this in both directions.
I could spin the wheel from one lock and it would rotate 2-3 times till it arrived at this central point and stop, I would encourage it past the stiffness and again it would spin feely till the opposite lock.
The stiffness isnt something I can really detect now it is back on the road but I am not sure if this means I should rebuild/inspect the box or whether it is normal? I am confident the stiffness is experienced at the exact point the box is mid-way between locks.
There is nothing wrong with that box, That hard spot is supposed to be there.
That "tightness" is what helps keep your car from wandering when you are going in a straight line. That is why it is important to set up your steering linkage so that the box is centered.
There is actually a torque value in the book, (I have a factory manual for a vega, how weird is that?), that specifies the amount of torque to pull the steering wheel over the center. If I remember correctly the value is 8-16 INCH pounds max @ the steering wheel with the pitman arm removed. The same value with the steering gear removed is supposed to be 7-8 inch lbs (including thrust bearing preload of 4 in-lbs) . The torque is supposed to be measured with a dial type torque wrench of no more than 50 inch lbs. Try finding one of those LOL.
On a used box I would not set it that tight. I will post up the procedure if you want.
If I were you I would leave it alone unless it is extra tight or really loose.
Hope this helps, mikey
thanks for the input Mikey.
I will leave it alone rather than screw with something that works!
