I don't know what PSI the power steering pump puts out, but I beleive that cylinders are big enought as the leaverage from the ski pivot to the ball joint is large. I needed to use 2 cylinders to keep the volume of oil the same for turning left or right. The big side of one cyl is plumbed to the small side of the other cyl then to one side of the hand pump. Also, my bombardier is a wide guage steel so I have enough room up front.

So how do the "hand pump" work ? Do you turn the steering wheel plus move a lever for the skis to turn, or is it all done in a single motion with the wheel ?? By the way I like the way you have the brake caliper set up. I think I will go that way with mine.
OT.
dpaulson:
It is all done in a single motion. It allows a bit of oil through when the steering wheel is turned. I guess that's why they call it a 'hand pump' because it will pump oil to the appropriate side of the cylinder even when the power steering pump is not turning (ie when the engine is not started) although you must put some effort into steering.
As far as the brake caliper goes, I was using the instructions that Cletus gave using the same parts in http://www.northerntracks.com/forum/index.php?topic=352.0, but in assembly showed that I cannot mount the rotor in the same direction as he did as I have the original rear end (Ford 9") and his has been replaced with a 3/4 ton rear end. There is a gusset at the bottom of the pumpkin preventing the installation that way. The rotor was turned around to have the offset facing the rear of the vehicle. I used the same brake caliper as he did. The only thing that I can say is that you can get the calipers for either the right side or the left side. The difference is where the bleed screw is. I got the wrong side and to bleed the system, my caliper must be removed and turned upside down to get the screw to the top.
I haven't posted much in this thread, but I have been working on it every weekend since the last pictures posted. I have put on about 10 gal of body fill. I am sure that I sanded off most of it. Somebody that knows what their doing could of done in 1/4 of the time that I spend, but it did turn out pretty good. There is a lot of dints and imperfections that accumulate over 60 years. I had the guy at the body shop bring his colour camera over to get the colour code of the original paint, before it completely disappeared from the body fill. It's came as Western Star medium maroon. I didn't realise that this paint is so pricy, but I hope it is as good as he says it is. I should get it paint next weekend.
dpaulson:
Just an update on progress. I really like the colour.
the old trucker:
Looks good my friend. If I had a metal bomber I would paint it the same color. I like it alot.
OT.
the old trucker:
When you get the undercarriage & rims painted she'll look better again !! I noticed in the last pic it looks like that "hand pump" as you call it, is fitted into the steering column itself. Any chance of getting a pic or two of how you have it done ??
I'm trying to think of how you open & close that valve to turn the skis.
A puzzled OT.
