That's not chewing gum. It's the weight they use to balance the spindle. It goes on very soft and flexible..like dough. It's soft like this to allow the operator of the balancing machine to "pinch" pieces off the weight to bring the spindle into balance. After 24 hours the "dough" will harden like a rock onto the wires, permanently.
Great explanations for beginners. Very encouraging. I am rebuilding a small greenhouse inflation fan there is rust on the copper wiring. What do you suggest I use to remove the rust? The copper wires are very thin and I don't wan to break them. Thank you.
Copper wires are coated in varnish, microscopically thin layer but critically important. Any cleaner that dissolves the varnish is counter-productive. Rust is iron deposits, they are water soluble. Test is with water and a soft toothbrush, then dry everything with air, See how that works out.
can you help me understand how you can put the wooden dowel to hold the brushes and remove it after installation? For my motor, I don't have enough room to put the wooden dowel in as there is barely any gap after I insert the commutator into the hole. Please advise?
@@DougWoodrow you can use any pipe strong enough and the right side outer diameter to fix the inner sleeve of the bearing. How much is that? A dollar? The old bearings can be cut off with any rotary cut off tool. 20$ maybe
Time spent shopping + delivery + scrap disposal + time spent with this all + cost of new machine with dazzling features not just bare basics like the old was = ... way more money than $20 for bearings

Cool, thanks!

The plastic that holds the carbon brush melted
Do you know where I can but that part
Hi! The two magnets inside are they glued in place? Or do they just stay in place because there magnets? Please get back! Thank you!
They are epoxy glued in exact place by manufacturer.
There not glued! they can come out! but they look like they were once glued!@@theoverengineer

Any thin piece of wood, metal strip, paper will do.
Thanks for watching!
Hi.thank you... How did you re assambly the bearings??
Thank you, very clearly explained!
So $12 for the 2 bearings, but how much for the specialised tool you mentioned?
When was it mentioned?
@@theoverengineer 11:42 "a proper bearing installation tool".
And isn't a bearing-puller also required?

Where can we buy commutator, winding etc?
try newark element 14 . com

i have smoke coming from the motor , but it's working fine
what may be the problem ?
- burning through the varnish on the wires. Too much friction in the bearings?
You saved 2500.00 dollars? You are joking, right?

2500$ for a threadmill?
Yes, they can be expensive.
