Having an issue with a several machines that keep stripping out the metal fuser gear in the fuser motor assy. Cleaned all the shafts and gears on the motor assy at first and then also cleaned all the gears on the exit assy. Has anyone else ran into this issue?

Yep, bad design.

Did you get the updated gear? It has a bearing center, there was a bulletin. But it's not indestructible either, since that motor runs so much.

(RANT START) You mean to tell me you are just noticing this problem? We have changed over 50 of them along with the M*%$#@ F'n motor (about 85% of the time), because the motor worm gear also strips out. Of course no warranty. Updated gear and expensive grease make no difference. Even if you make sure fuser PM's and duplex, exit, waste and drive systems are lubricated, still sh#t. (RANT OVER)

Diddo with Gazoo, carry one in my car stock.

I work with Kidaver. No, we haven't just noticed it, but we thought we'd try things before we asked. Of all the answers we wanted to see these weren't it. Yeah, we use the new gears. Ok, I'll pass this up the chain. Maybe a call to tech support will help????

I've also encountered this problem in the past. I've replaced the gear, motor, many many times before. I dont bother replacing them anymore...so I replace the entire fixing drive assy and haven't had any issues. I learned the hard way with a chargeable account. Went thru several gears and motor.

Damn Gazoo, you actually bought that grease? Was it made of liquid gold?

We've changed a few also. Including one machine that only went like 3 months then had do again with motor as well that time.

I've been rebuilding the fuser drive assemblies with the new motor, gear, and grease. We've been getting anywhere from 400K to 700K from the drive assemblies. Also, take the time to clean all the rust out of the rear. After the rust took out a few duplex PWBs I started making a mylar "shield" to deflect the rust dust from the duplex PWB.

As a side note, the other gears inside my drive assemblies are starting to look a little ragged. I'm going to have to start out with a few new ones real soon.

Has anyone had problems with the 620-820 machines? I started looking at the differences between the 6030 and 620 series, the only difference in the drive assy is the fuser motor.

Ordered the fuser moter for the 620-820 machines. The drive shaft looks a whole lot sturdier. Perhaps the shaft on the 6030 fuser motor would wear down and strip out the gear?

Just replaced the fuser motor with the one for the 620-820 machine. Got just over 300,000 with the last replacement. Will wait and see.

I have been getting closer to a million on them, I have been changing the fuser bearings and bushings every PM

I changed another one today, on the machine right next to the one I replaced Monday. This should be a better test as my last five copy counts between changes are 131895, 62762, 88670, 34236, and 220081 (latest count first). Techboy, we do not change out bearing and bushings that often, only when they look bad.

Bad news. One of the machines went just over 77 thousand before stripping out and the other went nearly 60 thousand. The first machine to die got a rebuilt drive assy, the other got a brand new assy. According to chi-tech, he (she) doens't have any more issues after replacing with a new unit. We are going to try and see. If the gear and motor are not the issue, then what could it be? The only other thing I can see would be the drive plate--somehow it gets damaged when these things strip out.

we have had better luck at replacing with new rather than rebuilding the old. take out the fuser and manually turn the drive gears that turn the exit assy. If it is hard to turn by hand, the gears, bushings, and shafts need to be addressed. There was a bullitin addressing the exit assy. it replaced the bushings with bearings. The fuser drive assy striping is a symptom of the drive train being to tight. Loosen up what the drive assy drives and the gear wont strip as often. We will also loosen the fuser pressure a couple of turns.
