I just have question concerning the Densi dev spacer rollers for the BH350 series. I was wondering if people have been replacing both or just the rear roller? I assumed they should be replaced in pairs just in case there is wear on the front one too. However I have read on here that techs have been replacing just the rear one. I need a little clarification on this. Please comment on whether you replace them in pairs or rear only.
Thanks.

My company developed those collars in early 2009. When we started with this we replaced only the rear one but since about 6 month's more and more machines are having trouble with the front seal as well and that's why we started to install on both ends of the mag roller the modified collars.

If I take it apart, I do them both.

We have only been doing the rear, simply lift roller enough to slip the space off and on. I have not yet seen a front mylar tare. Thanks Hans for coming up with this solution, whether you change one or both it is well worth doing.

Thanks guys. I think I will continue to replace them in pairs. Reduce potential callbacks.
