[ask]about ir5070/5570 fixing unit

The bearings will eat into the shaft of the lower fixing roller just like the ir8500. You can try to extend there life by bonding them to the shaft of the lower fixing roller with glue or by scoring the shaft with pliers and pressing the bearing on using the old bearing as a pounding block and hammering on the new one with it. I would then follow-up with silicon oil on the bearings at any calls inbetween. This will make them last the longest. The gears you mentioned are locked to the shield and that is why they have to be kept in alignment. The shield will not go back in properly if one of the gears gets out of alignment to the other. It will still take a bit of wiggeling to get it to go back in even with everything lined up.

Sorry simohayha, I do not have a handle on prices on these parts, because I do not order them. I do know, that even if you put every one of these parts in to Fixing Assy., it is still much cheaper than ordering the whole Fixing Assy., even if its refurbed.

1) Yes the shaft will chew up, thats why it was suggested to locktite them.

2) The pock pins-rings are so that the gears dont spin on the roller. The key of the gear is real thin due to the heater being so close the the roller.
