Repairing completely worn out stub shafts in flail mower roller.

Ғылым және технология

So, in this video I repair both stub shafts in a roller out of a flail mower.
With the shafts been so badly worn, the first job is to dismantle the remains of the bearings to measure the ID. Once the size is determined the old shaft can be removed from the roller end. This is done by arc air gouging the welds away.
Once the old shaft is out, I made the decision to bore the hole out to 40mm so a bigger shaft with a shoulder for the bearing to run against can be fitted. This will stop the roller shifting from side to side causing wear to the shafts.
The new shafts are made in the lathe.
After working out the measurements needed between the shoulders on the shaft, the first shaft is preheated and welded into the roller end.
The roller is then set up on bearings so that it can be rotated to check alignment and to weld. The end is then tacked into positions and aligned to an accepted amount of run out. The root weld was done with the tig welder, mainly just for me to have a practice in a real-world situation but also to get good penetration. The second weld was done with the mig.
After the first end was done, the second end was removed with the arc air gouger and the old shaft was chopped off then drilled and bored through on the lathe.
The same process was then repeated to weld the end on.
Hope you enjoyed the video.
Thanks for watching!

    I agree, I would approach the job using my strengths of machining and welding. This way utilised his strengths of gouging, turning and welding which resulted in a perfectly acceptable job, considering the state it came to him. There's no perfect way, but this was as close as it was needed. 👍 Great comment by you.

    I can tell you that even on brand new flail mowers the roller end shafts are not central to the axis of the roller! On mine, the rollers are around 5mm off axis. Not a big issue you might think, but the scraper bar that is supposed to clean the mud/vegetation off the roller is bolted to the chassis of the mower. This means the gap between roller and scraper bar varies resulting in poor cleaning. The more central you get the roller end shafts the better, so well done for minimising the error. Nice one!

    I'm so glad you gave a shout-out to Kurtis at CEE Australia. What that guy doesn't know about welding, gouging, line boring, lathe, and mill work is not worth knowing. I love his show, the diversity of it, even including Karen and their safety inspector, Homie on the act, crazy dog. Everybody is involved. FYI, that earthing device Kurtis uses he made. Scroll through his playlist, and you will find how he made it. It's so simple, really, and easy for you to make too Oliver.

    Really good repair, awesome job there. Just some tips for your tig welding: The needle doesn't need to extend that much out. The more it sticks out, the harder it will be for the gas to protect the weld and the needle from oxygen and also keeping the needle cooler. Looks like you burnt your needle, which reduces it's life span. There are some gas lenses, which will suport a longer needle standout, but generally it should be just around 5mm. Also for the arm you are welding with: It is a really big help to keep it supported. Maybe fix something on the L- profile you used to indicate the new shaft with. Rest your arm on there or on your leg, if needed. The better your arm rest is, the better you keep control of the welding, because the arm and therefore your hand is not that loose. Makes it easier to keep the arc at the welding point and not all around your part. This also ensures better control of your weld, because actually at TIG welding, you should be somewhere around 2mm close to the welding point. That improves the gas' job of keeping the weld free from oxygen.

    I did a Kuhn flail topper last year, exactly the same scenario. After a day of messing around trying to save as much as possible, i ended up binning the lot and starting over. I couldn't get the same size tube so ended up going a fraction smaller, never bothered with the dished end's, just some inch plate on the ends with the stubs welded in both sides. The bearing carrier's were completely goosed so just used some housed bearings and luckily i didn't have to drill any additional holes in the topper for height adjustment. Really enjoy your videos, see you on the next one.

    Yes, they do have a grease nipple on them. Self aligning bearings are terrible for accepting grease though. A lot of the time the grease comes out between the housing and bearing rather than actually going into the bearing.
