Looking at some used motors. Are the motors in the links below a viable option for the shredder?
Hi, I tried everything to get the spool off, and I appear to have broken my engine 🙁 The spool seems to be connected to some sort or bearing or something I can see it and it now comes out when the spool turns.. I fear I have broken it.
You can see in the video.. lucky it was only $220aud but I really don’t want to have to buy another, especially if the spool doesn’t come off ..
anyhelp with my new issue would be appreciated. and yes im a noob and yes i am not trained in any sort of mechanical engineering unfortunately
Can you take a picture of the end of the spool? Also can you push the shaft and bearing back in place? Does it rotate without wobble then?
Hi, thank you for relying. Yes I can push it back in although I have pushed it in hard just till it stops, you can see from the YouTube clip I posted previously that when I run the motor the spool works it’s way out. I will try and push the bearing back in place and see.
here is a photo of the end of the spool. Was identical to the YouTube clip I watched of the guy would used a mallet to remove the spool. But maybe mine is crimped to stop the spool from coming off..
What is that black, looks like heat shrink plastic, sleeve around the wider part of the shaft end. If that is plastic, I would cut it off to see if there is a retaining ring of some kind under it.
Hi, I assumed it was metal and recall it was cold to the touch, I will check tomorrow when I’m in the warehouse and see . Thanks
yeah, if it was mine, I would cut that black material off to see what is underneath. In the picture it almost looks like there are some threads on the shaft with maybe a lock ring?
Nope definitely not plastic. its part of the metal spool… not sure what to do now
I would go with the gear puller or a DIY equivalent that pulls on the hub while pushing on the shaft. Might be worth taking it to a local mechanic and they can probably pull it in 5 min. You can make something equivalent with a stout steel bar (or square tube), A hole near each end that you bolt (with a gap) to the hub and a hole in the center for something like a 10 mm bolt. You put a nut between the bar and the shaft, then as you screw a bolt through the nut (holding the nut), it should push on the end of the shaft while the nut pulls the bar (and the hub) off of the shaft.
Of course you could go brute force and carefully slice the hub lengthwise with an angle grinder with a couple of cut off wheels.
A mechanic may have an idea how to keep the bearing in the housing. I would probably just carefully glue it.
Thank you so much for taking the time to give your thoughts on the matter.. Because this is now a damaged motor to a certain extent, im going to use it for testing as the turning power hasn’t seemed to be affected, but the bearing does turn its way out.. I will see if I can hacksaw that end black bit to see if it releases the spool.. I have a mechanic friend that might be able to help.. do all the experiments on this and then maybe buy another and get it right..
Cheers thanks to you and to everyone who has helped thus far..
Hi, so I figured I would pull the motor apart to see if I can free the spool. I’ve already dropped down the rabbits hole so why not..
so after removing screws the spool came free and the shaft is still stuck tightly to the spool.
im at a loss.. I still can’t believe the guy on youtube did a few taps with a mallet and was easily able to remove this. He must of done something else and skipped it which of course means his video isn’t a proper instructional. I was duped 🙁
Well hell.. I finally did it. I removed the spool. I ended u removing the spool from the motor and then tapped (hard) on the tip poking out and it finally budged. The mallet just did have enough power..
thanks to everyone who helped, it really pushed me to keep going..
now to put it al back together and pray it still works 😉
but now I can buy a new winch and do it properly.
While I’m here annoying everyone, I need to find a coupler that can connect 2 different size diameter shafts.
@shredman, no worry, there is nothing annoying; much like Bart Simpon’s Teacher, said : ‘there are no stupid questions, there are just stupid people’. Nothing to worry.what you mean by ‘bueller’ ? drive shafts : I don’t know the torque of this winch motor but be prepared those motors or it’s gearbox is breaking some day anyways. If you can’t find anything, try to find a metal workshop with a lathe. They do you a direct coupling in 1 hours, paid rate of around 25-50$ the hour. Normal couplings are in the 50 – 200 Euro range. From what I’ve seen, folks break their couplings a lot. Get it big as possible! Those metal shops can tell you also where to get those from a trader near you.
Hi, thanks for the info. I will look into a lathe workshop and see..
bueler? Is from a movie Ferris hurlers day off. It’s used in a way of asking anyone for a question. It’s in reference to a specific scene . Just ignore me 😉
thanks for your help
