A snap ring designed to be removed with a *gasp* screwdriver?! Wow, Japanese precision at its best!Originally Posted by allan
Yeah.... I'm gonna have a hard time finding this bearing. I can tell already....
I've called Copylite twice about setting up an account, and Rudy called me back once, but I think we're playing phone tag now.
I just wish I could find a couple of these locally, or even on eBay or Amazon or whatever. I just don't know what specs to look for.
Searching for "Grooved 688z bearing" comes up with mostly nothing useful.
I think you are making a big deal out of something really simple. This bearing is used on many different models. Like I posted there are several of these bearings used in the FS-534 finishers and others. PM me and I will sell you 2 NEW bearings. $20 + shipping with paypal, venmo or zelle and be done with it!A snap ring designed to be removed with a *gasp* screwdriver?!

I agree that it would be simple, if I worked on these machines every day and had access to broken parts from which to scavenge bearings.
Unfortunately, I have to source everything new, so it's a real challenge for me, since KM doesn't seem to list that as a separate part #.
I appreciate the offer for the new bearings. I may very well do that.
I wasn't expecting them to be so expensive, but then again I haven't seen any pricing from Copylite either, so I guess I don't really know what I should be expecting.
I meant $20 shipped. Think Copylite price is $15.95 for 2 bearings + shipping should be around $20.I agree that it would be simple, if I worked on these machines every day and had access to broken parts from which to scavenge bearings.

Werd. lol
That sounds good. Let me get back to you on that. I'm pretty sure I'll probably take you up on it.
It never fails! One day after posting about the infamous fuser noise at idle I got 2 service calls for same thing, one C224e, C654e. Next day a C754e. On big machines, one had bushing wore on brush roller and frame cut a nice groove into shaft. The other had the cleaning roller bearing disintegrate and was metal to metal. On both machines I replaced cleaning & brush rollers, all bushing & bearings. One side note there is a new style bushing that goes into cleaning roller bearing. These seem to last longer. Also as been discussed here some techs remove the cleaning rollers from the C654/754 machines. I have done it one time on a C654 because customer didn't run 2 sided. Most of my customers with the production models run 2 sided so best to leave cleaning rollers in.
The C224e was the usual suspect, bearing was worn on LFR. Low volume machine. My theory is the grease dries out inside bearing as early as 3 years but usually happens after 4+ years on low volume machines. Most fusers have under 200k. Another thing I notice is the customers running high volume on these 22 ppm machines may never make the noise, unless of course you go way beyond rated life and eventually the bearings just break down from overuse!
You can use WD40 PTFE Specialist to lubricate the bearings. Might work or not, depends on how the overall condition of the fuser looks like. Ususally this knocking sounds comes from a lack of lubrication between the fuser roller and it's ball bearing. Best solution is removing the bearings and apply new temperature-resisant grease.
Aren't these sealed bearings? How would you re-lube them?
When the bearings are hot a couple drops of truflo oil seeps in and gives extra life. At least in my experience. Been using that or fuser oil for 20+ years for bearing creaking.
We know a thing or two because we've seen a thing or two.
