Do any of you have in your bone yard,parts pile or barn a 44" gage front axle and wish bone or just the modified wishbone that you would part with? I have the factory drawings to shorten the axle but not how to do the wishbone any ideas. This is for a 44" gage Snowmobile. Will make it
if I get help on the wishbone.
Should be a trig exercise Bob. As an example, if the thing needs to close up "X" degrees on a side, it would have to also get shorter by by the right amount - determined by the difference between the original angle and the new angle.
Spindles get machined?
I have several of both wishbones and axles. The 44" measurement would have to be checked but I believe they would be all just regular T. They are in a trailer I store at work.
How are you going to narrow the springs?
After the axle is shortened I'd take it to the spring shop and have the bottom leaf shorten
The axle would need to be 14" shorter than the standard axle. By doing this the the ski and wheel would be just off the center line of the track line (Ski inside - Wheels outside).
If you were doing the 38" gage model the axle,spring and wishbone would need to be 18"
narrower. There is a 38" gage model A Snow Flyer
here in Seattle. This also includes narrowing the rear axle.
My fingers are crossed, I should pick them tomorrow.
44" thread would be 12" shorter than a 56" standard axle. If all is shortened between the perches, each wishbone leg needs to be about 3" shorter to to fit the narrowed axle with the engine and front spring in standard locations.
(I'm using the old Pythagorean theorem here, forgot the rest of trigonometry from school - rarely needed in cad computer days)
