Replacing the rear wheels with sliders

(1/2) > >>

grfishmaker:
There is a video on the internet showing a few bombardiers that have had their rear suspension modified by having the tires removed and replaced with a slider type suspension. One machine has only the sprocket and the one rear tire on it while some of the others use two tires per side. It is a very interesting video and well worth the look. It also shows an old 1939 B7 along with a few other interesting machines. Some have been cut down and used as flat deck type vehicles.
The video was taken in St-Roch-de-Mekinac, Quebec and looks like it is some sort of rally similar to the Cranberry Portage Rally.
I sent a request to the person that posted the video to see if he/she could post it on our NT site and am awaiting a reponse. As the video is from Quebec, we may have a language problem.
 If anyone would like to try and view it, here is a few steps that will hopefully help.
1. go the Youtube
2. type bombardier snowmobile in the search box
3. click on one of the bombardier video
4. the one that is posted by fatssoalbert is the good ones. he/she has a few, but the one that is 4:45 minutes long is the good one.
5. if you click on his/her profile, it will show all of his/her posts and there are a feww well worth the look

  There will be quite a few different video choices pop up with bombardiers, but the rally ones have some good machines. There is one there that appears to have all mag wheels on the rear suspension, but may just be painted.

 Hopefully I will here from fatssolbert and inform us as to the suspension set up and perhaps send us some picture for posting on NT. It would be nice for him/her to join and past along the NT site to whatever club that happens to be out there.
 The Quebec event appears to be the same sort as Manitobas with some prttey nice machines.
Good luck and hopefully you will enjoy this as much as I did.

Ya I see what you mean.  Thats pretty interesting.  I wonder if it has more "rolling resistance" compared to wheels.

the old trucker:
Great job Grfishmaker. Great job!!!!!

Well, I hit a dead end with trying to get hold of the person you posted the video as it says "no such member" when I try to send him a message. So below are some photos from the video that shows some of the machines had I was mentioning. One of the video is already "no longer available", so hopefully most of you have seen it or check them out before they are removed. If not, here's a few pictures to enjoy (quality is lacking).

Check out the fancy rims. What do you think hub caps, paint job or something new?

How about a 1939 B7. Looks like it was made yesterday.

Two tires per side on rear suspension.

How about only one rear tire and a sprocket?

Here's another flatbeck with the rear intact.

The video was taken in February of 2008 and shows a great number of machines of different years and styles. Most of them look as though the were made yesterday and is really a very facinating clip to watch.

I can see a slider system working on a bombardier if you never drove off of a flat surface, but I can't see how you would get any spring in the suspension if the slider is one continual piece. Would it not make for one back breaking ride? It would be like if you ran with solid wheels and no bogie suspension? No difference. You would have to duck tape yourself to the seat, and then head to the chiropractor after every ride.
They must have something that we cannot see clearly in the video that gives the machines a bit of movement in their suspensions.
I have a contact in Quebec through work that has volunteered to be a go between if we can find out any of the owners names.
