Salvage a Gibbled Rim

[bc.gold 3,403]

One of the wide rear rims has the holes wobbled out. found a donor this afternoon at then a trip to the farm cut the center out nice and clean with the plasma.

 

I'm going to cut out the gibbled center then weld in the replacement then give the finished rim a rattle can pain job.

The donor is going to be a prefect fit, tire is tubeless, once the old center has been removed I can weld in the replacement with out having to remove the tire which is an added bonus as it's loaded.

The majority of these center pieces are spot welded into place while on a few that I've sen had a full bead weld along the edges of each tab, my replacement will be a full bead made with a mig welder. Might even ask one of the fellows at the farm to do the deed as my eyesight is not what it used to be by a long shot.

 

Each of the four tabs has two spot welds about the same size as those black dots indicating where the welds were placed. Now that I'm aware of this will zero in on those spot welds removing the cobbled center piece.

 

I suppose the holes filled in by the spot welds could be drilled out again then reassembled as they came from the factory, might consider do just that.

 I had that happen to a backhoe once. It seems that the factory did not weld the center to the rim properly and in use, the practice of using the backhoe to shift the tractor  sideways and scooting it about on the earth finally fatigued the metal on the rim, When it let go, you should have heard that whoosh of air!

  The center was still in good shape and we cut it free from the rim in a "sloppy" fashion with a cutting wheel, and then grinding the small pieces of rim away from the wheel. We tapped the old wheel center to the location in the new rim and spot welded it to two places by measuring. Kind of a problem because these are tractor rims and not very accurate.

  But wait! We had a perfectly good machine lathe to true things up a bit... We simply mounted the wheel to the back hoe and fashioned a metal rod to some concrete block jig/ indicator gauge and spun the wheel by using the outriggers on the backhoe to lift the wheel assembyl off the ground and spotting it to the wheel. The differential in the transmission allowed us to set the other wheel against the earth for additional stability. As the wheel spun around powered by the tractor it was easy to see when it got closer and further away from the fixed indicator rod. After fussing for a bit, we decided on a good average of all the defects in the rim and declared it good enough

 It remains a much less wobbly wheel than the factory welded wheel on the other side of the backhoe

Good thing yer back hoe tire wasn't loaded with calcium as it would have only been about 2/3rds full changing the center of gravity while truing it up on yer big machine lathe.

 

If the tire on the other side had a wobble did that not allude you to a potential problem such as that you were already making a repair.

 

On a side note, farmers no longer use liquid filled tires it has been found that using suit case weights improves fuel economy.

Lifting that heavy loaded tire onto the truck found that my chain is much to long, for what its worth thought I would share this old trick that I use

 

1. image loop chain making a cross then take the loop forward pull section of chain through the loop hang on hook. After removing the chain from the hook shake one end the knot unfolds.

Old center removed, donor is now in place all that is left to do is adjust the offset then weld it in place. Once you know where the spot welds are this job is a snap to do.

Had the Allis out for a test run the only complaint that I have is those wide tires on the front that make steering a two handed job, my Simplicity 9020 with tri rib fronts and a 400 pound snow thrower mounted on the front is one flat hand palm on the steering wheel.

 That wide front wheel has a wobble, bent rim.

Fooling around with Allis today when she bogged down into some very soft ground. this is when the loader came in handy, curl and push while back out of the two trenches that I had made.

 

Allis is thrifty on fuel as most of my work is at half throttle or less cleaning out the shop of all the useless scraps and loading all into an old pick up truck that will be picked up by a local scrap hauler next week.

 

The Simplicity 9020 blowing snow at full throttle loves her fuel.
