Heres one to thank Ricoh for!

The small Sharps I have to work on also have similar bearings. They use fuser sleeves and they never make the popping noise.

I think that it is a combination of some movement and too much heat on the small bearings.

Sometimes I can get the noise to go away on old bearings, if I don't have any new ones with me, with some motor oil. Only a temp. measure, but I'm thinking that they dry out . Fuser sleeves, man, fuser sleeves.

He He.. I feel you on the lower frames, but there's a lot I could thank Ricoh for... Ld035/45, 5634/45... lack of proper authentication for smtp and no smb capabilities.. yuk yuk!!! 5685 in a 300,000 copy a month enviorment... not good.

Another tip that I use when the frame piece breaks is to take the screw out of a A230-9510 drum ( the long one that holds the bearing down) and put the screw into the hole that the ground wire attaches to on the metal frame piece that holds the pick off fingers. That screw is long enough to keep the bearing from moving around and keeps you from having to rebuild the frames. This only works if the plastic lip on the gear side is broken but that seems to be the one that breaks most often. I think like previous guys that people arent putting these back together correctly and causing the stress on that gear side lip because they arent getting the hot roller seated correctly then turning the machine on and cracking the plastic. Just my two-cents, but I have done this on several machines and not had any callbacks because of this fix.

Square peg, large hammer...

I agree that these are the easiest fusing units to service in the field. The problem lies in the fact that too many technicians don't take the time to tip the hot roller up high enough to gain the clearance around the bearing. They force the bearing out of the frame, breaking the flange. I've had some (limited) success bending the upper frame down at that end to keep the bearing in place.

I don't know if it is the caliber of the technicians, or the productivity demands being place on them. Too many employers today don't want PMs done on schedule, or at all. Also, too many have been avoiding PMs for so long that all they have time to do is put out fires.

Also, two other part numbers for the same bearing are A2323559 and AE030030? or was it AE030003? We used to use them before the change to the groove-less bearing by stripping the ring off the outside. But if you think those are expensive, try getting the same bearing from Toshiba, it costs three times as much. F0-something... from the 200L-283 series.

And the Barrierta grease does work wonders on those clicking noises. But it only lasts about 75-90K, whereas the PM cycle on that roller is 120K. The bearings on the pressure roller never seem to have the problem, or go bad, just the hot roller.

I've thought that these were one of the easiest fuser assemblies I've ever worked on, yet it amazes me how many techs I've followed up who must have thought they were round hole/square peg assemblies.

Maybe assembly/disassembly comes not just from being in the business for years, but for having a specific attention to detail towards this type of work. People have said to me, "Hell, I could do your job." Really? Here's my tools-go for it. Oh, and good luck figuring out WHY I'm changing what I'm changing. Yeah, you'll surely succeed.

Not to get off-subject, but when I've been in training schools, it really made me nervous to see the technical/mechanical skill of the other techs in class. After that, maybe I DON'T wonder about the whole round hole/square peg situation.

I just don't know if the caliber of tech has changed for the better or the worse over the years. Personally, what I think is happening is that we'll see more IT guys that attempt to troubleshoot copiers and it will continue to evolve into a more hybrid position, as it's currently doing. Some of the old-school techs I've talked to really do not like getting involved in the IT portion of the job, which is where this business is going fast.

This just follows up the post about incorrect installation-sorry about being winded.

1022 lower fuser frame

My best time for replacing a lower frame is 1hour 15 min!
As for the clicking noise Ricoh did release a little "L" shaped bit of spring steel that fitted between the flats on the hot roller and the bearing. Warehouse told me they had been back ordered, since that was several years ago I think I'll stop holding my breath!!!!!!

I'm thinkin, if you think these are easy to work on in the field, you have never worked on the old sharps with the clam shell fusers. They were truly 20 to 30 minute rebuilds.

[schooltech]

Like the Sharp AR405-507 era, or even earlier? I've found these to be very easy as well.

Older, I think the SF 2022, 2027 era.

I have been using the drum screws from the 9510 drums
and installing it on the black ground screw.
It keeps the bearing in position . This eliminates the need to replace the lower fuser housing. Did this on 4 copiers and no callbacks.

A nice to use,,,,,1224 silicon oil on those bearings work wonders,but the bearing must be hot while putting the oil on it!!!Takes that noise away for a very long time!!!
