Wedge plate on H

What was the wedge plate between the pedestal & bolster for, and did the thick part go forward or to the rear?

I don't remember one, and my old partsmanual doesn't show one. But it's an interesting idea, I've always wanted to put the front wheels further towards the rear. DO NOT know if that's a good idea.

100% guess here as I'm not sure I know what you're talking
about (Case guy), but any wedge should get wider to the
front, tipping the wheels back. You sure wouldn't want them
tipping forward.??

It was to reduce shimmy when your bolster was worn. I can't remember now which way it goes. I have it wrote, oops, written down somewhere.

it was to reduce steering effort. thick part back. ih built this angle into the late model tractors.

FBH44 · Dec 8, 2013

well we got it narrowed down to either the front or the back...

They moved the pedestal back to improve steering so you want the thick part to the front

Did it on the M sure made a difference wide to the front as I-H moved the pedestal back to improve steering.

Whatever the reason some of the wedges have front stamped or cast on the thin side for the intended use.

Gene is right about thick to the front. But that wedge is very over-rated if you want to stop the front wheel wobbles; there is one on my H and the front wheels still wobbled badly in 5th gear...and the wobble did not stop until I fixed all the worn parts of the steering gear. My H had a loader on it for many years, sure fire way to wear out the front end.

if it is to reduce steering effort it would be thick part forward to put negative caster into the steering , which would aggravate a high speed wobble. If it is to reduce high speed wobble would be thick part to the rear to put positive caster in the steering for increased stability but would increase steering effort. The simplest illustration of caster angle is a bicycle, the front forks are farther out at the bottom than the top creating positive caster increasing stability so when you take your hands off the handlebars it still wants to track straight. If you reverse the forks it is hard to keep straight and if you take your hand off you eat asphalt.

Agree.

Janicholson · Dec 8, 2013

The bicycle idea is not as simple as it seems (though correct)due to the head bearings in the frame being at a rake angle already. A tail wheel on an old rake is easier to envision. (its pivot is vertical and the trail is dramatic) if the wheel were directly under the pivot it would have no tendency to follow the lead of the frame. The farther the offset to the rear the greater the self steering effect will be. Jim

(quoted from post at 19:41:42 12/08/13) . . . The farther the offset to the rear the greater the self steering effect will be.

And the greater the tendency to wobble. A shopping cart is a good example of a lot of caster. The wedges were intended to reduce the wobble by reducing the caster, thus the thin side of the wedge belongs forward.

If you are trying to accomplish something else, installing one backwards may serve your purpose.

The wedge is marked with a "FRONT" cast into it.
