Thread: Centrifugal switch replacement
25/07/2023 21:38:18

Thank you for all the suggestions. This is the new switch. Its construction is different to the original switch - the arms that hold the springs. On the old switch they (the arms) were quite delicate and ‘pegs’ on the ends of the arms slotted into a grooved channel on the collar of the Bakelite. It was one of the arms that was broken, requiring replacement of the switch.
the windings are good and all else is functional. The wires just needed wrapping with insulation tape as the rubber coating was perishing due to age.
the new switch has a locking nut at its base to hold it in place on the shaft. It appears I’ll have to try and remove the cast piece of the old switch.
‘The motor is for a cement mixer so I’m not sure that I can add a relay etc and fit it all under the motor cover (plus this might be a bit beyond me)!

Appreciate everyone’s help!

Here are a couple pics to show the part of the switch I am trying to remove. The small alloy arms holding the springs were broken, hence the need to replace. It does look like it may have been cast in place?

It may be beyond me to fix!?

Can someone please help me - I am trying to fix a Newman Elf motor, specifically, replacing the centrifugal switch. I am trying to remove the cast collar section of the old switch off the shaft so I can slide on the new switch.
It appears it sits within a machined groove, I’m guessing, to hold it in the correct position. Problem is it looks like I have to remove the shaft from the other end. Do I have to remove the shaft by first taking off the part that the belt sits in and then slide it out?

I’ve tried to take off the bit that holds the belt by unscrewing the locking nut but still can’t get it to slide off? Maybe just stuck from years of grease and grot? I have given it a good spray with WD-40 hoping this might loosen it but still not budging.
My other option is to carefully angle grind through the switch collar to remove it??!! Not my preference

I’d much rather fix this than throwing it away as the rest of the motor is fine, and probably a whole lot better made than motors today. If anyone can help by giving a step by step instruction that would be appreciated as I can’t find anything online that shows or explains this.
thank you.
