Tires/Gear Leg/Toe In

[tps8903]

Chris,
I had 3 thoughts on how to do it:
1) weld up the axles and then redrill.
2) make a sleeve, drill to the gear leg. Slot the original. Get it lined up, mark/tack weld it, then weld for real.
3) buy new weldments.

Would like to see your setup for checking alignment.

I took the tires off the rim. Used metal straight edges clamped to the face of the rims. Measured, did the math. Just like a car alignment. They are visibly toe out which was alarming before I even measured anything.

How would one match drill the hole with new weldments?

Somebody had a picture of description. I'll have to see if I can find the thread. Basically you make a drill jig aligned with the gear hole. It is clamped onto the gear leg above the weldment.

I guess I'll have to see how far it rotates to the new position before I decide which method to use.

From a practical stand point. What would be the problem with drilling a new hole slightly above the original?

I had a similar issue. I had a machine shop relocate the mounting holes at the engine mount. This involved rotating the leg the required degree, and use a 5/16 bit. Then I bushed the hole back to 1/4.

I had the same problem. I just removed the bolt. Did the alignment, drilled a new hole about an inch above it 90° to the original hole and installed the bolt there. Then I elongated the holes in the weldment and installed second bolt in the original hole through the axle. I really should weld that back up and re-drill but I decided if one bolt was good enough to maintain the alignment. I didn’t need to do the second bolt properly.

Thanks,

That's exactly what I wanted to know.

Started swapping my tires tonight. This is about 110 hours or so.

Wow! Fortunately I fly off grass, most of the time - I am hoping for a long tyre service life

Wow. Are you sure you have the correct alignment? I guess you can extend that if you swap them every oil change. Any opinions if it would be ok to just swap the whole wheel, in which case the direction of rotation would be reversed? Is there a bearing problem if you do this?
