Replacing Centrif. Mechanism

[8270tom]

When replacing centrif mechanism on Westinghouse combo and backend motors, I use red super loctite to fasten mechanism to armature sets up overnight and turns rock solid.

I get rid of them for the relays......c-mechs fly apart causing damage.

I replace them out with Cybernetics Solid State Start Switches, but only when the C/f mech has worn or needs replacing.

I agree with Alastair and King. I just replace the mechanism and switch with a SSSS.

Tom,

I think your going to regret using red loctite…that stuff is just about as permanent as you can get next to welding. Usually takes a lot of heat to get that stuff to break loose. If I were going to glue the mechanism down, I would use a milder loctite that is used as a bearing retainer.

Too much trouble dealing with centrifugal switches and mechanisms. I replace any bad switches (boards) and mechs with Motor Start Relays (like Stahl's brand, also available from Grainger) on the combos and SSSS on the backends which I mount inside the rear control box.

I do this because no matter how well you keep up on maintenance, you will still have those few centrifugals crap out during league. Reliability is enhanced greatly using any of the above mentioned products.

Why even mess with C-Mechs, just as Kat said they'll just crap out. SSSS are great and trouble free. I like the lewis SSSS for my back-ends and Quality brand on the combos, but both work great where ever you put 'em.

Wire your SSSS with Molex plugs and if one should happen to fail, then you cna snap another SSSS on in seconds.

Thanks, will try your suggestions on SS replacements on my next repair. Didn't have to take mechanism apart after loctiting probably will be a bear to remove defective mechanism.

<font size="2" face="Verdana, Helvetica, sans-serif">Pack a rag around the base of the shaft to keep filings out of the motor, then apply a Dremel with a heavy-duty fiber cutting wheel to the centrifugal plate... cut through an edge to the shaft. Don't cut all the way through... leave the last hair of metal and break it loose with a screwdriver to keep from scarring the shaft. Use a little sandpaper to get rid of any loctite residue.

Re: Replacing Centrif. Mechanism

our owners will not stretch to solid state units, we have since found a source of incredibly simple cent mechs and with the use of the retro-fitted braking relay, the motors have become incredibly reliable. i only change maybe 2-3 cent mechs a year even with our heavy lineage

Alastair,

Who sells them in the uk ?
