Replacing front registration roller bearing/bushing LD118

[Vista David]

Hello all,

I had my first run in with a broken front registration bearing/bushing (part number AA080269) yesterday. I had no previous knowledge of this being an issue until I was troubleshooting a skew at a customer's office and found that the piece where the spring attaches was broken. Long story short, I need to replace that bearing, but I have no idea the best way to go about doing so. Also, in my efforts of troubleshooting, I knocked the rear bearing out of position, which I later learned is a big no no. Any advice on how to replace the front bearing as well as re-positioning the rear bearing would be greatly appreciated. Thanks!

It can be a bit tricky, but you'll have to make sure the rear bushing is not getting out of position when you replace the front bushing.

But don't worry, I think everyone made that mistake when they replaced the bushing.

X2. Before you pull off the front bushing, clamp the reg roller with a pair of vise grips at the rear end on the inside of the frame to keep it from shifting to the rear.

I fear that I've already knocked the rear bearing out while I was messing around with it yesterday . What's the easiest way to get that front bearing out? When I was looking at it, there didn't seem to be a clear way to remove the old one and put in the new one without pulling out that whole assembly.

No, it's not that difficult, just will take a little patience. Remove the front door and front inner cover to expose the bushing. You will have to extend or better yet remove the slide out lift handle to get full access. Remove the 2 clips on the gears of the left and right reg roller. Also remove the spring bracket to the left of the reg roller. Now remove and replace the bushing. All this is done of course with the rollers locked in place so they don't shift to the rear, which you state is the case already. You can get access to the rear and get those bushings in place first, it should be obvious once you see it (though there may be some items in the way you may have to remove). A spring hook will come in handy on this job to catch and hook the spring.

I'd personally replace both bushings anyway, so the fact that you pushed the rear one out of place is not that big of a deal. It's a lot more rare that the rear bushing breaks, but I have seen it happen. Both bushings have been modified to make them stronger, thus the reason I recommend replacing both.

If you elect not to replace the rear, you will need to remove a few items to get decent enough access to the rear bushing. Remove the sprint from the rear bushing, then slide it back into place and re-attach the spring.

Once that is done, you can then secure the rollers as others have stated, or just be extremely careful when installing the front bushing, and don't push on them, or at least hold them in place when trying to install the bushing. I personally don't worry about clamping them. You shouldn't have too much of a problem with them moving when installing the bushing, the problem will come when you are trying to install the gears...

To get the old bushing out, and the new bushing in, the easiest way is to remove the lift handle in the front right corner. One screw on the right side, just above the handle (there are 3 or 4 in the area, just loosen them at first to find out which one is the correct one), and then one screw on the front side. The screw on the front only needs to be loosened enough to allow the handle to slide out of the side of the machine, and let the handle bracket come out through the front.

Replacing the bushing is easy. Replace it (don't push rollers out the back!) and attach the spring. When reinstalling the gears, install both gears at the SAME TIME. If you didn't secure the rollers, slide the gears onto the ends of rollers slightly, then hold the rollers with your right hand through the right side, and push the gears on with your other hand. If you don't do them both at the same time, you are going to have a much harder time getting them on, as they have angled teeth, not the typical straight teeth.

It's not that hard of a job, but I understand where it can seem quite daunting your first time. Good luck.

Yeah I fucked up there too the first time I had to replace the bushing. I don't like the sound of rear parts falling apart during doing something at the front

I wouldn't replace the rear bushing since I've never seen one broken so the extra effort doesn't really justify the prevention of possible calls in my pool of machines and we really have a lot of units out there.

To each his own. The rear isn't that difficult to do, but like we both said, it's much more rare that the rear breaks. Leave it up to the OP to decide I guess...

Alright, got the part in and installed it this afternoon. Thank all of you guys SO MUCH! It would have taken me ages to figure out how to realign that rear bearing without you. The front bearing was a breeze after I pulled out the handle. Next time it will only take a fraction of the time it took me today. Thanks again guys, you're all lifesavers!
