I bought a pair of split 'bones represented as 36 ford units to use on my dropped heavy 32 axle. Both 32 and 36 axles and bones should be 2 inch but when the 'bones arrived they measured out at 2 and 1/4 inches. I believe they're a split model A wishbone. I have no first-hand experience trying to insert a 1/4 inch spacer to make the split bones fit a 2 inch axle but don't see why it wouldn't work. I'd like to keep these split bones as they're really nice. Anybody tried using a 1/4 inch spacer to make this work? Any problems?
Speedway sells 'em, so they must work fine! http://www.speedwaymotors.com/2-Inch-Axle-Boss-to-2-1-4-Inch-Bracket-Spacers,31781.html
spacers are common fix. Have never heard of a problem. There should be a big difference in the length of the bones. I.E. Model A compared to '35. What is the length??
i have done it and it works just fine i actually think mcmaster car sells a thick washer that is perfect...if you dont want to go the speedway route tk
That's right, common fix. (Most axle mfrs. offered these spacers when they only had axles with 2" bosses...) Spacers go on the BOTTOMS of the axle bosses.
I just cut a slice of 1-3/8" round stock and made a spacer that more closely matched the diameter of the wishbone yoke. Blends in and is not very noticeable.
May have a proposition for ya...i bought bones represented as 2.25....and well they are 2".....and damn near perfect bones. My '32 heavy duty style (from CE) is a 2.25, did you opt for a 2"?
I also have some 32?? split bones that are 2" axle boss.....not as smooth as the ones above. If you want pics of the 32? bones or wanna work something out...let me know Whats the length of the ones you have?
besides being 2 1/4" wide at the perch yoke, the model "A" wishbone doesn't seem to have as much ( if any) positive caster built into it as the `32-`34 does. you might want to cut the tube apart at the factory weld to the yoke forging and cut a pie section out and reweld it back together with more caster.
Has anyone ever heat and bent the yolks? on a 2.250” wishbone to match the 2” axle? I bought an old hot rod with a 32 axle and model a bones, and the wishbones “yolks” (front part) are bent to 2” in the back and 2.125” in the front so the spacers I bought won’t work. I was thinking of just bending the front to 2” to get them to work.
I have never seen this but the ends are forged so I assume it is possible and that someone has done it. That being said, it would be tough to keep the eyes parallel when bending them. IMO, the spacer is by far the easiest way to go.
haven’t checked the Hamb in a while, but if anyone will check this down the road, my friend and I ended up heating them back within 0.010”. We c clamped the yokes together and heated the top part of the yoke and then slowly pulled in the c clamp. Worked like a charm. It wasn’t necessarily bending the metal just heating it up within the fixed c clamp to allow the metal to “relax” back to the 2” spacing. We went too far and used vise grips that push outward and brought it back into spec using the same process but in reverse. I used calipers to measure the backside and frontside of the yoke.
Fyi. 35 and 36 bones are 2 inch They look similar to 37 up, which are 2 1/4 Just bought a drilled so cal axle at 2 quarter, and need to use the unsplit 36 bone for 2 inch Worth noting. Perch pin bolt lengths. 5 inch long 4.5 under head 5/8ths 16mm just a tad bigger if wobbly Socket cap screw, milling the taper washers
Just curious (I’ll most likely never need to) is the top and bottom shimmed, or top or bottom, or makes no difference?
The shims I bought on Speedway (think they were in the beginning of this thread) gave me 4x 0.125" shims so I am assuming they go top and bottom. That being said, I read in the vern tardel book that if you do use shims they go on the bottom. Looking back, I should've just made the spacers myself on a lathe and made 2x 0.250" spacers out of stainless, but I didn't need to after straightening the wishbones I had.
