Can you tell visually when these need replaced? Of course the primary indicator would be in reg, but I'm just levelling out arms, platens, heads (thanks for the info Brian) currently.
Bearing don't seem to move when pallets raised in the forks (I have a Performer / Challenger II) but I heard that if bearings change from black to silver, through wear, it's an indicator they may need changed?
Just wondering if anyone one else has experienced this!
Thanks (:(https://uploads.tapatalk-cdn.com/20171104/10ffc971e2b4bb5f9f20494f4b59e9b8.jpg)

Looks like normal wear for an older machine IMO. Checking with a test print would answer the question. As long as the center shaft bearing is good the rest can be fixed.

Thanks for that Binkspot, I have a couple of platens that seem to be consistently out of reg from what I can tell but I'll be doing a large grid test print with all the heads to get a better idea.
I'll finish levelling off and see how I get on!

We replaced all forks and bearings when we had our press installed - CH3 came with over 4 million prints though.
It was noticeably out of registration though - like by at least 1/16" left to right which was insane to see...

They are easy to change and relatively inexpensive and you wont have to register the press afterwords. I would go ahead and change them out to prevent any fork wear caused by bearing wear. just sayin

Cheers for the advice guys, mines 5.5 million prints, Performer (challenger 2). I'm getting 2mm left to right on a couple of platens...
Replacing all three forks and bearings is what I'll do, a couple of flood bar holders on the print carriage assembly have some movement so going to see if that's just a tightening needed or if anything swoops out. Just sorted a few leaks today so the ringing in my ears is no longer drowned out...

If you move those forks you are definitely going to need a tech. Just a FYI.

Haha I didn't actually mean personally for the forks and bearings! 'Good with a manual' does not extend to me attempting to do a techs job on my first auto Rich
Got Someone from M&R Poland booked in ;)

very happy to hear that. I was concerned.
