51 R18 Rebuild

  I have to agree with you KPM. She's definitely looking 100% better already...

Well, parts for the steering and brake never showed up, so I spent my time re-skinning the doors.  I only had 18ga sheet to work with, so after I cut the pannels out about 1/2" wider on the straight to about 1/4" wider on the curves, I bent the straight parts to a 90 deg in my brake.  I used a ball peen hammer to fold the sheet over the angle frame.  The last door only took about 1 hr.  I went on a lot better than I had anticipated.

This weekend I reskinned the cargo door, install the hydraullic cylinders for the power steering,  fabricated the brake peddle set up and installed. and installed the rotor and caliper setup.  The brake peddle and master cylinder were salvage from on old electric fork lift.

These are the cylinders for the steering

This is the hand pump I'm using to control the hydraullic fluid.
It is salvage from an old Massy combine

I have to apologise for the poor pictures, I need to get a new camera.

  What diameter & length are those cylinders & where did you get them ??

Those cylinders are from princess auto 1 1/2 Dia X 12" stroke. 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.

I think you should wait to see if I make it to the Cranberry rally.     You know, I can talk the talk, but can I walk the walk?

[the old trucker]

  Please correct me if I'm wrong, but could you tie those cylinders into your power steering pump ? Wouldn"t it look after turning those cylinders ?

I called it a hand pump because it is known in these parts as a hand pump.  It really should be called a steering control valve.  This control valve is connected to the power steering pump also.  I have it hooked up now.  There is 5 3/4 turns of the steering wheel to go from extreme left to extreme right.  It can turn the skis while the machine is at rest while it is sitting on concrete floor.  I don't know if it can do the same in snow where the ski runners are dug into the snow, but it should work fine while moving.

  Thanks for the learning experience. I know I'm never too old to learn.
                                                                                                 A smarter OT.

    Kpm you didn't take any pics for this ol' trucker now did ya ??

[kpm]

no  I did.nt.....I hate to ask him....as it is a VERY unique system,which will fit either a wide or narrow guage...and i'm not sure of his plans of as yet....i'll see what I can do..
                                                                                                          kpm
  he owns 6 bombardiers,so once he's done his and my 2,i'm sure i'll be able to get some pictures.
