4345

Hello all

i've got a job on monday on a 4345 which has had the swing gear replaced by another tech and the noise is still there.. he reckons it's the gear which drives that which is worn. anyone out there got any experience of changing this.....anything to watch out for?

thanks

if you have replaced the full swing plate assembly on a 4350 a few times it should be the same just it has more components to remove thats all.
here are some pics of my last call in which i replaced the swing plate assy.

thanks for that Rick. we have only ever had the swing gear and disc supplied from stores. i see there is the whole bracket which that fits into.

yes the assembly is kind of tricky the first time but after that you will get the hang of it, that picture was my first time replacing the whole assembly and took me about 1.5 hrs.

check youtube for a very good instructional video.

This link is very useful. make sure you account for all your screws.

Re: 4345

great video, you used to be able to get the swing plate kit which had swing plate assy and fuser gear. replacing swing plate assy and fuser gear/fuser unit, is the way to go. just replacing the gear and spacer disc the problem would come back very quickly.

Impressive. I believe it took me about 2.5.

i have literally done hundreds of these in the shop. Since we already have the covers off for cleaning, etc, it takes me less than 15 minutes on a 4250. 4345 longer as there is more stuff to remove.

One thing is after mounting the swing plate, its a good idea to check the drum drive arm that attaches to the lid and make sure it moves properly. I think I usually make sure its down when installing the plate. I forget, its like auto drive when I do it, lol. I also put the machine on its side when removing and reinstalling the plate on a 4250.

Re: 4345

I know this is an older post, but someone may have need of this information again:

Just a note, if the damaged swing plate has been in the machine a while it might have damaged the main drive. (Sometimes you meet a gem of a client that decides to wait to call a tech because "it's noisy, but it still works." If so, you will end up having to replace the Main Drive. ) Main drive > Swing Plate > Fuser is the way the machine is set up. If you have changed the fuser and the swing plate asm and you still have noise the main drive is your next step.

IMO, the LPR bushing is the culprit in all of the 42xx/43xx swing plate issues. The bushing gets worn, the LPR starts to wobble, and then the fuser gear damages the swing plate gear. If you are just replacing the fuser gear, make sure you replace the LPR bushings at the same time. Otherwise, you will probably have this problem again. Some techs like going out every other month to change the swing plate. It's up to you. I do not.

I have attempted to attach step-by-step instructions for replacing the swing plate assembly in the this machines. Hope it helps.
