Suggest you look over the Lonestar Wheel Weight web site.

Wheel Weights - Lonestar Weights

Kubota and other manufacturers were often buying third party products and marketing them as factory stuff.

I had read that in a previous threead but there wasnt any info on who the third party was, thanks

Are you actually tightening the bolt? (or is it stripped and just spinning?) the spring acts as sort of a lock washer and is supposed to prevent it from vibrating lose...

It is tightening however the wheels are still wobbly

I suspect with the pins in place ( not all worn) and the securing bolt tightened, the wheel should be secure.

Investing $13 in two new pins would seem wise

Dave M7040

I understand now that I was correct in what I had noticed and that was that not only are my pins worn but also the wheel itself and most prob the axle. Its not stupid sloppy but Im used to working on more precision tolerances

The chances of finding OEM wheel weight bolts, for a bizarre set up like you have, is about zero. Myself I would buy long enough normal bolts, You could grind large washers to custom fit the rim, then weld it to the bolt head, and insert them from the inside of the rim. That would make it so you just have to use one wrench to remove the weights.

Consider it done than. Its no problem

The pins are typically sloppy even when new. The compression bolt with the spring is what tightens the wheel to the axle. Still, that wheel fixing system wasn't the best system for holding the wheel firmly. It isn't in use on many - if any - modern tractors. And never was popular or much used on tractors much larger than yours.

It's an inexpensive way to hold the wheel on and it won't let the wheel slide along the length of the axle if the pins and their keepers were in place. But they were known to be a bit wobbly. It is what it is. There are ways to shim it to work a bit better, but if you put in the pins and tighten that bolt it will get you by.

BTW, you can buy bolts to mount those weights at any hardware store. Yes, the heads will be too big to fit. That's not a problem, simply grind the heads until they fit.

The whole point of having an older tractor like this is that it gives you a chance to exercise your creative mechanical side. I'm betting you are way ahead of me and that you started seeing that with that ridiculously expenseve air filter spring.

Being able to understand when you can legitimately use a simple solution is half the fun of old tractors.... and exercising your ingenuity on a nice little older tractor is a great way to learn mechanics the right way. Pretty soon you will not only be making the simple parts yourself, but some of them are going to be better than the originals.

good luck, rScotty

Tractors in pretty good shape in my opinion, Im assuming not many around cause of all the attention it gets when I take it out somewhere, Id like to preserve whats left with correct parts if avail, I have lots of other projects that Ive spent alot of time exercising my ingenuity on.

You give some of the best detailed responses. thanks

The system holding on the axle will always be sloppy and break pins. Ordinary bolts work well as a replacement. Duct tape wrapped around the hub will hold the pin pieces in place when they break keeping the wheels in place on the axle. Trying shims helps abit but they will quickly wear out. Kubota has a replacement hub for these type of hold downs.

A lot of those old style hubs broke the safety retaining pins when the compression bolt with the spring either came loose or was lost. Then the hub would wobble on the axle and break the pins. We now know that whole hub wasn't a very good design, endless adjustment and trouble. It just wasn't up to handling the forces a tractor puts on the hub.

A diligent person can make it functional by fitting things carefully, but replacement with an upgraded type of hub to axle fixation would sure be a better answer. Still, if the compression bolt and spring are still there and with good enough threads to tighten down well.... plus pins or bolts as you say - then he could get by for awhile.
I didn't know that they had a replacement hub type. That would be a better long term solution.

Fitting carefully works for a very short time in my past expierience.

The little Yanmar I'm rebuilding is about the same size uses about the same hub tightening system. But it was apparently never run loose because it has remained tight for decades now.

You know..... what really interests me is finding out what the upgraded hub fixation looks like. A few posts back someone mentioned that Kubota offered a replacement part that worked better. I'm curious what it looks like.
