7 Degree Taper

[Neddo]

Hello All
I’m sure some of you have had this problem before.
The 7 degree taper in my steering arms is to deep…not the correct word, maybe oversized is better.
When castle nut is done up snug split pin hole is above castle nut.
A thick washer would make it better but that’s not how it should be.
I’m sure there used to be a tapered split shim you could get in different thicknesses to fix this.
Does anyone know if there is in fact such a thing and where I may be to get a couple ?
Failing that I could Macgyver some up out of shim stock.
Or is there a better way I haven’t thought of ?
Thanks, Neddo

Sounds like the depth of the taper is machined/ reamed too deep and does not match the taper diameter of the steering arm. I've never heard of a tapered bushing to correct that. It would probably be a quite thin walled bushing!

A washer below the nut is not a problem. Check with another rod end to be sure it’s not worn.

The thicker washer seems to be the way to go!
Maybe one of the bucketeers will chime in!

Shim stock cut to shape (Cone) will sort it, or see if a mate with a lathe can machine a shim, it's reasonably intricate to machine.

Thankyou for the replies
To complicate the issue my tie Rod runs below the lower four bars. I have to maintain a minimum of 1/2” clearance. With 3/16 washers I am to close !
Shim stock it is.
Annoying having to do this with “ quality” new parts.

Tie rods can be closer than 1/2”. They go up and down with the radius rods. Any clearance during full steering movement is good. You know caster angle will affect clearance. Is yours close to 7 degrees?

 

[Neddo]

Physically I know the tie Rod won’t touch but our rules here in Aus dictate clearances between components.
Caster is at 7-1/2 degrees relative to the floor.
I did a test today with a shim and It will work good.

Just curious, how thick of a shim was needed? I'm thinking .005" thickness is probably all you would need.

Watch the scrub line.
