Jog Wheel Maintenance on VCI-100 and VCI-300

29

In today’s video Chris, A.K.A. PhotoJojo, takes us through the process of fixing a VCI-100 jog wheel that spins unevenly or wobbles. This technique can also apply to fixing VCI-300 jog wheels, which have the same mechanical structure and similar issues. Be sure to also check out our writer’s last video log, where he demonstrates how to get your faders sliding silky smooth again.

ADJUSTING LOOSE OR STIFF JOG WHEELS ON THE VCI-100

Often times I’ll see complaints of jog wheels that seem to move differently on the same VCI. One may spin freely and the other will make a revolution or two and stop dead in it’s tracks. Another problem is jog wheels that are to loose and have a bit of side to side play to them. Sometimes tightening the screws on the top plate can solve the problem with loose wheels, but other times the problem can only be corrected by opening the jog wheel assembly and adjusting the collar that sits around the jog wheel post. Adjusting this collar may also solve a problem with your VCI causing Traktor to turn sync off due to vibrations from loud club systems moving the jog wheels.

Supply list

  • Phillips screwdriver
  • 1.5 mm allen wrench
  • Container for screws

The first thing you need to do is remove the three screws from the top of the jog wheel. Be careful when your removing the metal plate, there’s a spring under there and it is possible for it to going flying across the room. If your adjusting both jog wheels I would recommend doing one jog wheel at a time just to keep things organized.

Once you get the jog wheel off remove the four screws from the top attaching the jog wheel assembly to the case. Steady it with one hand, flip the VCI over and remove the back of the unit. You have one screw on the bottom and two on each side of the VCI. Slide the cover slightly to remove it and set it to the side.

Slowly lift up the jog wheel assembly paying attention to the thin wires and making sure not to pull to hard on any of them. There’s four screws around the edges of the jog wheel assembly that you’ll need to remove. After you get those off gently pull the jog wheel assembly apart. You can set the back of the unit containing the contact finger to the side, but be careful as it’s still connected with a wire. After that you can lay the main part of the jog wheel assembly back down. You’ll be able to gently rotate the post to see the allen bolt in the collar.

You’ll need a 1.5mm allen wrench to loosen the bolt. Once you do, the collar, which is also attached to the mirrored disc will move up and down. Next you’ll pinch the post and apply a slight downward pressure on the collar with your fingers. It takes VERY LITTLE pressure to get adequate tension between the jog wheel and the collar. While your applying the even pressure you’ll tighten the allen bolt back up.

Check to make sure everything spins correctly and there’s no side to side play indicating the jog wheel is to loose and put it all back together. Once again be careful with all of your wires making sure not to pull to hard or pinch any wires between the two pieces making up the jog wheel assembly.

CHECK THE OPTICAL SENSOR

While your inside the jog wheel assembly you should check the optical sensor to make sure there’s no dust or lint between it and the mirrored disc. If you do see something in there just gently blow it out rather than try to remove it with something. You could risk damaging something if you try to dig it out.

REASSEMBLY

After getting the jog wheel assembly back together you’ll need to check the white bushing on the back of the assembly to make sure it’s lined up correctly, loosen all three screws and make sure the bushing is centered well and then tighten the screws a little bit at a time making sure to get them screwed in evenly.

Next you want to turn the VCI over to it’s front. As your holding the jog wheel assembly against the inside of the faceplate with one hand so you can flip the VCI over and line up the screw holes once again checking to make sure no wires are being pinched between the faceplate and jog wheel assembly.

Once you get the jog wheel assembly screwed back on you can move on to the next one if you need to adjust both jog wheels or continue with putting the VCI back together.

There you go, a straight forward guide to adjusting your jog wheels to get a consistent feel to them on both sides. Let us know how this worked out for you in the comments.

    I need some help please….

    i’ve just tried to fix a wobbly platter and now after i’ve put it back together the right hand platter is not sending midi data (other than data to say the platter is being touched)

    So now i cannot move the track forward or backward or pitch bend with it.

    Has anybody else had this problem and managed to sort it out? i’ve had it apart a few times now to look at it and still no joy….

    i hope i haven’t just broken my vci!!

    any help will be greatly appreciated.

    thanks.

    • Roy

      I didn’t opened mine but I’m having the same issue with the right hand platter… it lights up the led right when I touch it but I can’t move forward or backwards!! Does anybody has experienced this?

    Can anyone in here please look at my thread, as I think some of you guys might be able to help me out πŸ™‚

    Thanks in advance!

    No, but I have heard of at least one person contacting Vestax directly and getting a replacement.

    Great vid… I’ve actually done this on my VCI-300 to fix a wobble. Worked like a charm…

    I’m not real sure. My best guess is to improve the sensitivity of the jog wheels. Or possibly to put upwards pressure on the metal plate to keep it from loosening. I’ve seen people mention needing to tighten the three screws, something I’ve never needed to do.

    Do you have the holes for the springs? You can try and get in touch with Vestax through their website and see if they can help you out. You also might be able to take one of the screws to a hardware store and get one to match. Same with the spring, but it won’t be an exact match.

  • vangelis

    i also don’t have any spring and i thought that i accidentaly lost them.
    when i had the same problem i used silicon lubricant and then i had no problems.

    Sorry guys that should have been in the description. Springs were just added in the last several months so some people may not have them.

    Great, helpful video. Definitely notice a good number of VCIs have this problem.

    Last time was the fader, this is a completely new video… thanks photojojo!

  • djelevation

    This is a recycled article, but helpful. I was having super erratic line fader issues in Traktor and cleaning them worked like a charm.

    I did this cleaning on my VCI 300 as well before I sold it and it worked quite well.
