cds clutch

[Dwain Ray]

Well Ogura, Pitts, etc say you don't know wtf you are talking about and they make the things.

I didn't want to post and I PMd him the other day but I don't want others following your bad advice. Most manufacturers call for the key on 5 sec on then off cycle 25-40 times to burnish a new em clutch. Not doing so potentially reduces its torque handling capabilities significantly.

The Basics of Electromagnetic Clutches and Brakes

Electromagnetic clutches and brakes seem simple, but complex variations fit them to multiple applications.

AI/google is not a substitute for critical thinking and proper research especially if you don't know what questions to ask

*the caveat to this is clutches that are specifically listed as pre-burnished

When you tell someone they don't know wtf there talking about you should be in a place that you can back it up. I dont burnish electromagnetic clutches and find it unnecessary now you my friend said i was wrong and quoted clutch manufacturers . So i reached out to Pitt and got a response and it left me wondering who really doesn't know wtf there talking about??? Some just read others actually know wtf there talking about and i sir am of the latter! I am a person that will admit when im wrong. But when it pertains to this subject , yes there is a recommended procedure, is it absolutely necessary, NO. By not doing the procedure will it cause damage and/or shorten the life of the clutch? Not according to the manufacturer.so in short as far as im concerned and backed up by the manufacturer you can go ahead and burnish the clutch, just wear out that switch of yours as for me i won't nor will i recommend it. I will however offer it as an option when asked next time

It literally says there is a recommended burnishing process you delusional potato. I also linked you to several pages on Ogura's site (the largest manufacturer) showing how and why. Not only that but to Pitts installation instructions showing the same.

You also have post in this thread from suppliers (Pemberton) saying you should.

Not burnishing can significantly reduce the torque transferring ability of the clutch.

Hell you (still) didn't even know how to properly ask the question of Pitts based on the reply....you didn't include your email to them. Maybe email him back and ask why burnishing instructions are included in their literature...

Some just read others actually know wtf there talking about and i sir am of the latter!

I have no idea what you're talking about when you say burnish im assuming you are referring to bedding/ transferring material from one surface to another ( like braking in brakes) if so i wouldn't worry too much about that .

anyway....like I said I was just posting so others would have the correct info....carry on

Not according to Pitt as for the other guy i don't know the situation and neither do you . For all i know the guy stuck a clutch and magnet on and didn't set the magnet gap. Ive run pto's since 1997 and have logged in excess of 18,000 hours on them i have never burnish ed a clutch nor have i ever had a clutch fail because of that . Ive had 3 or so have magnet failures and 1 had a bearing go out but none have had problems associated with clutch surfaces i replace clutches on a regular basis on my machines as preventive maintenance . Steamgeni driveshaft has 2 double row sealed bearings that require replacing approximately every 2500-3000hours when i replace the bearings(rebuild the driveshaft) i replace the clutch at the same time and put the old clutch on the shelf as a used but good part incase something does break so far ive only used a couple of the magnets so bark all you want but Pitt said no damage will come ive seen no damage and youve only quoted damage youve heard of so as i said before in giving advice in the future i will tell people that there is a procedure but in certainly not going to get up on a pulpit and preach it

It does say there is a "recommended " not necessary procedure. It goes on to say that the zinc will wear off under normal operation. It goes further to state that not doing the "recommended procedure " will not shorten the clutch life span so as i said before i don't know the whole story of Mr. Pemberton's customer and anything I would come up with would be a guess. But if you're going to call me names. Im just going to block your comments i don't find them to be conducive to good professional dialog and have little if any respect for anyone that resorts to that

You are the one that keeps talking about failed clutches and lifetimes. How many times do I have to say "burnishing is to insure the clutch operates at its rated torque capacity". ?

maybe that just isn't as important on a vintage steam genie

and despite your email answer the Pitts clutch manual (screenshot above) says to burnish. Why? To insure rated torque transfer capability..........



So in conclusion for posterity if folks would like their clutch to work as rated burnishing should be done.



and yes...we all know how you hate name calling and just want professional dialogue

Whatever... agree to disagree
