Wallowed out tie rod end hole on a steering knuckle on a 4WD John Deere
tractor. $1800 part. Got a new tie rod, trying to figure out the taper
so I can get a reamer. It's a ZF front
axle, so it's probably metric. Does anybody KNOW what the taper is?
Looks really close
to 1 in 12, but is it?

Source for a left hand spiral right hand reamer?

Thanks,

Bill

You might either make a casting around the male taper or turn a matching
female taper on the lathe. You can then then measure the taper as accurately
as it really is by measuring the depth of two different size balls in the
hole. Ideally the large ball should go just over halfway into the large end
of the taper and the small one should stick out of the small end slightly
less than halfway, but it is not critical.
