Bearing Block XC540

Do you have the service manual for it. Pretty sure it shows how to disassemble about every thing on the machine.

 

I have done this on an old CJ 500 and looking like I might have to do the same on my Sp 540 V. For the CJ I bought just the bearing blocks directly from THK, Installed them and the machine worked fine for a few more years until it died of other causes. I would try not to disconnect the ink lines, could you tie the head assembly out of the way?

 

I took the heads out and slid the carriage off the left end of the linear rail. I think there are some preloaded spring attachments on the back of the carriage which were tricky to deal with but it's all doable. I don't think any of that is it the service manual. I might have an extra bearing block or two. We just retired our xc540 a couple weeks ago and I think we had brand new spare linear bearings since they are so hard to get. Will be selling all the parts from our xc540 as well

 

Have been a service technician for roland for years, and have never replaced the linear bearing where the carriage slides on, never had a worn bearing. If the sound of the movement of the carriage gets louder and louder, it is more likely the scan motor.

 

FrankW, Do you recall how to get the time on the scan motor on XC-540?
Edit: Disregard getting the time on the motor(s) = I found that. I'm amazed at how LITTLE time shows for the amount I've used the machine. Is there some unusual way that it is calculated?

 

Friends, my scan motor seems even noisier and I have bought a replacement. It seems easy enough to replace but I wonder what must be done/adjusted/etc. after replacement beyond resetting scan motor hours?

 

The spring should put the right amount of pressure on the gears. Snug up the screws, but not tight. Just run it back and forth by hand before tightening the screws to make sure that the gears mesh properly before you tighten the screws. Then put a small amount of grease on the gears and wipe most of it off. Run it by hand again to distribute the grease and again wipe most of it off - excess grease will just fly around in there and that's not good.

Good Luck

 

Many thanks. Changed scan motor but still have some noise. Apparently it is something else being noisy.
