    The latest information is at the bottom.

    There seems to be two problems. [1] There is a loud clicking noise. It only happens when the flywheel under the back cover is spinning. But, it used to do this yet still make copies. [2] Now, the paper jams just as the from edge is entering the fusing unit. They seem to be related. I tightened the fuser unit to the body of the copier and the clicking went away and the copies went through the paper path. But, that only lasted for 4 copies. Now it's back to the same problems.

    ===

    I tried a new drum and the same problems occurred. So, it is not the drum. Where is the presser roller? Also, I should mention, I tried tightening the two screws that hold the fuser assembly and two copies did go through the copier. Then it stopped working and the same problems occurred. So, the problem for the paper jams may be with the fuser unit. Is there and secret for how tight the fuser unit should be screwed into the printer body? Of course, that still doesn't correct the clicking noise. Thanks for your help.

    I have some further information.

    If I remove the fuser assembly there is one white geared wheel on the fuser assembly. I sprayed a little drop of wd-40 on the sides of that gear and turned the fuser roller. I also cleaned the toner off the white geared wheel.

    That gear meshes with two gears but thicker white rollers on the internal body of the copier. They are on springs and appear to move a bit back and forth. One of them clicks but not a loudly as the problem clicking. I also similarly lubricated those two geared plastics wheels a bit. None of these three white plastic geared wheels are missing any teeth.

    After I've done the above, the copier prints fine for a few copies. Then there is mild clicking and eventually the problem comes back. that appeaers to be simply when the lubrication wears off.

    Any help on actually fixing this will be greatly appreciated!! Thanks!!

    I think it's all been said. I'm looking right now for the correct lubricant. What is it called? Of course, that's just my guess of what's needed -- see earlier descriptions and comments.

    Thanks!

There is problem inside the fuser assembely. Open fuser unit and make sure there is not any paper jam or not any small paper pieces.Make sure roller inside fuser unit is fine and not torn or corrupt. This problem occurs of paper stuck or roller is bad. If roller is corrupt then you need to replace it then it will work again. Let me know if you need further assistance. Thanks for using FixYa.

    Is there a web site or video (e.g. u-tube) which will instruct me in how to remove the fuser unit? Also, I'm beginning to think it's the fuser gear. How do I remove that gear? THANK YOU for your help.

There is something mechnically wroung with this copier. I would have the fuser taken out and looked at for the cause as you said when you nailed it down tighter it worked and now it does not this will be the fuser exit causing this issue.

1. how long ago have you replaced the fuser
2. how old is the machine

let me know ether way so we can make a determination gong forward.


thanks

    WD40 sure will lubercate but not for this type of lubercaton, there is some clear white lube called machine greese witch is basically put on these gears to last a loooong time. Now if you can get you hands on some of that great stuff, no not magic you just need to get some your machine might take it, but at this point it sounds more or less wear that has caused this clicking and jamming. I will leave it up to you weather you need a new fuser or not but I sure highly recommend it. NO there is no special magical torq to put on the fuser screws



    let me know, thanks

  • fir2 Aug 06, 2010

    I've never replaced the fuser. The copier is three years old.

    Remember, it worked for a while after I lubricated those three wheels. I'm wondering if a heavier lubricant (e.g. vasiline?) would last longer and may be what missing. Oh, I just saw you said that. OK.

    There is a special white grease we use between the cpu chip and it's heat sink and fan in a computer. It is the highest quality great I've ever seen. I'm going to try a drop of that.

    My guess now is that there is something causing a jam between the two spring-loaded white gear wheels and the back cover. Of course, that doesn't fit with the lubrication solution. Any ideas?

    Thanks.

    I am feeling that when you bolted down the fuser and it worked then stopped there is some issue where the fuser meets that needs a special look. I like the thermal compound idea LOL



    Vasiline = Epic



    I was talking about machine greese or oil.. But your got the idea or hey try some bearing greese you get from a auto shop that will do it.



    now for the jam issue i am kinda leaning on the side of the fuser since you never replaced the fuser since you had the unit this brings me to think its past its prime. Let me know

  • fir2 Aug 06, 2010

    I've got bit more information which might be helpful. I put some of that cpu grease on the two spring loaded white gear wheels on the inside of the copier. Nothing improved - clicking and paper jamming. Then I put a drop of that grease and a drop of wd40 on center circle of the white gear wheel in the fuser assembly (it surrounds the fuser lamp actually). THe copier ran nearly silently and no jamming. This lasted for about 10 minutes. So it does seems as if it is something in the fuser assembly that's keeping the fuser rod from spinning easily. What is the name of the grease you were making reference to. Maybe I can find some locally.

  • fir2 Aug 06, 2010

    please see the new comment I just added to you just below.

    Try bearing greese or machine oil!!





    You can get it from the home depo!!



    there is alo generic multi purpose!!





    You might have to replace the fuser as a whole it might be getting too hot and burning off the lube!

How to fix paper jam.

It seems inevitable that the copy machine will have a paper jam. You need the copies immediately, so how do you fix the jam? Luckily, ingenuity and a manual, can help you fix the problem yourself. Fixing a paper jam, can elevate you to hero status amongst your co-workers.

Things You'll Need:

  • Copy machine manual.
#step 1

Discover the location of the jam. Carefully open the cover of the copy machine and the paper tray to see exactly where the paper is jammed.
#
Step 2

Turn off the copy machine before pulling out the paper.
#
Step 3

Pull the page out, the opposite way it is fed into the copier. Pull the jammed sheet out gently. If you tug too hard, the paper may rip.
#
Step 4

Check for any paper fragments and clean up any torn pieces.
#
Step 5

Check the roller where the jam occurred to be sure none of the copier parts are loose or broken. The roller should be smooth all the way across with no possible snags.
#
Step 6

Replace the cover and paper tray and turn the machine back on.
#
Step 7

Press the button to cancel the paper jam message. This button will vary among copy machines. The display will tell you which button to push.

Tips & Warnings
  • If you cannot fix the jam yourself, ask for help. It’s better to have help than make the jam worse.
  • Test to be sure the jam is fixed by only copying one sheet at first.
  • Never try to copy pages with staples. This will more than likely cause jams.


How to fix clicking noise.

The fuser hot roll gear and the small white drive gear have worn out. They will have to be replaced.

Problem also experienced by us. Taking the printer apart revealed the fuser assembly had a broken ring gear. Couldn't find a replacement part and it probably would not be cost effective anyway.

GE front load is making loud banging noise during spin, any ideas how to fix?


Sounds like what happens in a top load when the load is "out of balance". I suppose it's less likely to occur with front load. Test with a "light" load. Is the washing action a reversing action? If so there may be a transmission problem.

Loud Buzzing when turning key


Something is froze up. Try rotating the engine "key off" to see if it is jammed. Then remove engine cover to access the starter motor.
It should spin freely. If there is no apparent problem remove the flywheel and inspect the shaft key and magneto settings. If you need more repost.

Clicking noise coming from around flywheel.


If the car is an automatic, it will have a thin metal flex plate, rather than a regular flywheel. If the flexplate gets a crack in it, it would cause a bit of noise. See if there is an inspection plate on bottom front of transaxle. Remove the inspection cover to look at the flex plate. Turn the engine over to view the flexplate all around. Look for cracks, maybe a loose or missing mounting nut where torque converter mounts on flex plate. If you see nothing, leave the inspection cover off, and run the engine and listen closely for a problem from that area.
Leaking oil, eh? Don't know if related, but while looking at the flexplate, check if motor oil is leaking out the rear main crankshaft seal. It will be fitted to the rear engine block, in front of the flex plate. Oil would be dripping off the rear of engine, or maybe collecting at bottom of bell housing, evident when inspection cover is removed.

My Nordic Track 1300 Commercial elliptical makes a loud clicking sound on the left side as the left pedal returns from front to back. What is the fix for this?


Dear Sir:

Thank by your request, I hope everything is o.k
I will try to help you, inmediately.

1)
Pedal Arms
1
Use aflat screwdriver to unseat the tabs that hold the front top cover in place. Thiswill expose the flywheel and pedal arm connection points. Rotate the flywheelby hand and determine whether lubrication will accomplish the repairs. If thebearings are exposed, use a grease gun with an extension nozzle and lubricateboth bearings with lithium grease. If the bearings are damaged or sealed,proceed to the next step.2
Removethe front and side covers on the main frame. Hold the flywheel with one handand use a box wrench to loosen the bolts that secure the pedal arms at eachside of the flywheel. Pull the arms away from the flywheel and remove thebearings from each side.3
Test thebearings as before. Lubricate exposed bearings with lithium grease andreinstall them. Sealed bearings must be replaced. Reattach the pedal arms tothe flywheel. Replace the main frame covers and front top cover to complete therepairs.
If you need further assistance, please reach me.

Thank you in advance, sincerely. God bless you.

Motor was ticking loud,parked it and the motor made a noise , now the starter is just spinning, could it be the flywheel?


yes, if the starter is spinning freely it's basically telling you that the gear is not engaging to the fly wheel. the only way to be sure is to crawl under and take the trans dust cover off a visually inspect.

yes could be a bad fly wheel. we have had them on our 1996 van and it is exactly as you describe. you do not hear it revving the engine. you will need to get under the truck . remove inspection cover for trans. look very carefully with a flashlight for reflections from the cracks in the flywheel. we tried to pry ours and it did not move. but we saw it with the flashlight both times. 2 flywheels were made one with ovals and one with circles. the oval ones always go bad. do not buy an aoval replacement

"howling" noise during spin cycle (still there after changing burned off belt)


Travioso, there was two service flashes out on this model concerning the seal and bearing which means they had an issue with this washer. The howling noise you are hearing is the bearing and will need the new designed triple seal and bearing kit. This should be covered under your warranty, I believe it is 5 years. The numbers for the service flashes are TDL-0048A-B. Call Maytag and inquire about these service flashes, these should be covered. Catriver.
