Replacement Bucket Spinner Shaft - (Updated: 06/02/23)

Update: - (06/02/23)

New v2 File: I have made a newer version that has a sloped internal ring to help push the new shaft on. You can use either versions and try them both to see which suits you. I would recommend trying the v2 first to see if it fits properly. If not then try the v1 which has a thicker internal ring (not sloped).

If your Bucket Spinner has seized up, become stiff and is squeeking, then it is more than likely that the shaft grease has become hard.

Instead of spending a lot of money on a replacement bucket spinner, you can print a replacement shaft for pennies.

To remedy this you will need a replacement plastic shaft that connects the spinner to the metal shaft of your bucket.

This is it.

Instructions and info:

My replacement shaft spinner will ONLY fit 8mm shafts which is the standard size for most bucket spinners. If the metal shaft is wider or thinner, then this will not fit your bucket spinner. The replacement plastic shaft should fit most bucket spinners as they have roughly the same size square cut out on the spinner to fit the plastic shaft.

You will need to remove your spinner from the bucket which usually entails removing the bucket outer rim cover first photo 2. Lift out your spinner to reveal the plastic shaft. This will need to be removed and in most cases, cut off with a junior hacksaw (this is how I removed mine). Be careful not to cut the metal shaft and use pliers or similar to help remove it. (Various cuts may be needed). The plastic shaft may well be brittle and will snap anyway which will help remove it.

Once removed, clean the metal shaft photo 3 as best as possible and remove ALL grease and dirt that is on it. Do NOT re-grease as this replacement works without it. If it is rusty then try to remove it with a file and WD40 or sandpaper/emery cloth.

The replacement will need to be pushed on as far as you can get it and then with a piece of wood on top (to protect the plastic) hit the replacement part with a hammer until it clears the shaft indent. Once it is on far enough, the shaft will spin freely. So hit it, try to turn it, if it does not turn hit it again, and so on until it spins without force photo 4.

Then put the spinner onto the new shaft photo 2, replace the spinner outer rim cover (if you have one) photo 1 and you will now find your bucket spinner works better than before.

TIP: Print more than 1 so you have a replacement at hand if you need it.

The photos show mine after a lot of use and the bottom of the shaft had broken off from the main part but it is still useable. You can always replace it with another as they are quick, cheap and easy to make and fit (especially after the first use as you no longer have to cut anything off).
