JVC LA11 - How to replace the main drive belt.

[@inter7847]

Thanks, this was really helpful, I’ve been trying to figure out my uncle’s record player for a while now.

[@Isdale]

Cheers for this video, not only did I learn how to put the belt on without looking like a moron, I realised that the cause of my turntable going slow was because the centre spindle was completely jammed.

[@yung.bol_she-vik]

Thanks for this! I had a turntable running slow that had a fairly new belt and in trying to remove the platter I found that, like many others in the comments, it simply didn't lift off. Used some WD40 around the spindle but had to actually use some grips to hold the spindle still while turning the platter to get it unstuck. After that just added some WD40 on the spindle bearing itself and put it back together, working perfectly now.

Excellent video. What if the center spindle does not move?

[@gbaudio1212]

If the spindle does not move, then the spindle bearing will need to be cleaned out and lubricated.

@@gbaudio1212 I came here to ask the same thing! Is there a video that includes this bit?

[@gbaudio1212]

@@RocktheProject We've not had a player with a stuck bearing for a long time. The next time one comes in for repair, we'll do it on video.

What are the two screws either side of the motor spindle for they move about with the motor movement

[@gbaudio1212]

They are holding the motor in place. They move because they are mounted on rubber bushes which isolate motor vibration from the chassis so that it does not transmit through the chassis - spindle - platter - record and get picked up by the stylus. Some turntables use spring mounts to achieve the same thing.

Great video - thanks.

Thank you so much !

Hello, can you tell me what to do if the spindle starts spinning immediately when plugged in ?

[@gbaudio1212]

That sounds like the micro switch for the motor is stuck in the ON position, not uncommon with decks which have not been used for a while. The micro switch is under the deck and it engages with the tonearm when in the rest position. A little squirt of switch cleaner should free it.

[@rezatabatabaei4545]

I bought one but it does not have a headshell. Can you please let me know which headshell is compatible with this turntable?

[@gbaudio1212]

There are many standard headshells which will fit the JVC, Technics and other Japanese turntables with an 'S' shaped arm. We sell an ultra-low-mass headshell for £12.41 with regular wires or £27.95 with Van-Damme wires. gbaudio.co.uk/data/cartridges.htm

Mine simply will not come off even if I lift it up on the two holes and hit the center spindle with a hammer it's stuck so hard it's like it's welded on. I know I was able to remove the splatter 20 years ago the last time I changed the belt

[@gbaudio1212]

Wow, that seems really stuck. Try some WD40 or similar round the spindle. Let it work in for a while then get someone to hold the platter by the inspection holes, so that the whole deck is 1cm off the table, while you gently tap the spindle with a hammer or mallet. Be very careful doing this because the when it does come apart, the deck will drop onto the table. Good luck.

[@basspig]

@@gbaudio1212 I tried all of those methods including heating up the platter to try to separate it. I ended up using a special brake removal tool to pull the platter off but that apparently ruined it I could not get the platter back on again.

[@gbaudio1212]

@@basspig Oh dear, that's really bad luck. I've never heard a story like that before. Was it the spindle or platter which got damaged?

[@basspig]

@@gbaudio1212 Both the spindle and platter. I could not get the platter back on, so I drilled it out a bit, but now it wobbles.

[@yambo59]

You really should have cleaned the old belt material off the motor pulley as well, it will gum up you new belt and cause problems in the future

[@gbaudio1212]

Thanks for that suggestion. Maybe, to be thorough, I could have said to check the motor pulley for debris, but in this case it was totally clean.
