Garrard Model 1000 turntable will not work automatically
Hi folks
This Garrard Model 1000 turntable will not work on auto, with the turntable running and a record sitting on the spindle, by moving the lever to auto and releasing it, there is no action mechanically and record will stay where it is. The spindle pushes home OK and the only clip I can see is the one that holds the platter down, I don't really know where a clip is supposed to be fitted underneath for the spindle. I have had the platter off and the large gear seems to stay where it is, that is with the flat adjacent to the small gear on the platter shaft, for some reason the large gear does not appear to get activated by what ever activates it from underneath. The exploded view of the turntable from its underneath view is a little complex and can not work out what is supposed to do what at the moment. Ken |

Re: Turntable will not work automatically
Your problem is hard grease in the linkages on the deck underside.

Re: Turntable will not work automatically
When you push the stacking spindle fully home, you will hear/feel the spindle locate itself. It does not fit into a "clip" as such.

Re: Turntable will not work automatically
The clip that holds the turntable on also secures the spindle, so that's all correct. The fault you describe is due to the trip mechanism, which is seized with old grease. Basically, you need to take the large cog off, and remove the small swivelling mechanism attached to it's edge. Thoroughly clean all the parts, reassemble, but do NOT oil any part of the trip mechanism, it relies on friction alone. For fuller instructions, see the "stickie" at the start of this section entitled "Automatic trip repair on Garrard Autoslim - chassis units"

Re: Turntable will not work automatically
Thank you Edward and Barry,
I may have to seek another clip, and it wasn't until I looked carefully at the spindle I realised the groove in it associated with the platter. As for the auto part of it I looked at what you said Barry and it all became very much clearer as to how this worked, but I did notice though the did notice the lug on the small cog on the platter was worn a little, but will try as you suggest and get back to you with a report. I had the audio going quite nice but for some strange reason it seems to have gone very quiet, I did change the cathode bypass cap, just maybe the cap I put in has gone defective. Best wishes Ken |

Re: Turntable will not work automatically
Hi folks
I am still having trouble with the deck on this player, I managed to get the turntable to switch of by physically moving to arm to the centre, but it will not allow a record to drop, I took the large gear off and cleaned as suggested but could not get the part that sits below the gear to come out and where it is riveted to the pin that is intended to be on the plate is loose. I am still not sure if there is anything missing as yet from the underside of the deck. I have put pictures so you can see where I have got to Ken |

Re: Turntable will not work automatically
If the shaft on which the Cam Gear turns has worked loose, the cam may not be in the right position relative to the spindle. I once removed a stuck cam gear by pouring hot water into it's central hole. This melted the hardened grease, allowing the cam to be easily lifted off. The same method also freed off a seized platter.

Re: Turntable will not work automatically
The large cog must have ALL the trip parts removed and cleaned. The bit you have left on will come off if you heat it, either with a soldering iron, or dropping the whole thing in boiling water.

Re: Turntable will not work automatically
Thank you Audio1950
I will try this and see if it does the trick, the cog being die cast aly I being a bit put off as I thought the cog would snap. I will have to obtain a new circlip for the platter though. I still wonder, if there is still something missing from the works underneath. I have now replaced all caps on the amplifier but still might have to get another cartridge, this one is a BSR X2HE.

Re: Turntable will not work automatically
Don't recognise the BSR cartridge type number X2HE?

Re: Turntable will not work automatically
Hi folks
Have solved the auto section of this record player, I did leave the large gear in hot water for a few minutes and the swivel plate did eventually come out, the reason it was fitting tight was that the pin that goes through the gear was 4mm in diameter, the hole in the gear was 3.5mm so I drilled the hole in the gear to that of the pin on the swivel plate (part 45) but where the pin is riveted into the plate this had come loose so I tightened the rivet up and applied a small amount of solder around the rivet edge. Put it all back together and yes I had intended to replace the circlip that hold both spindle and turntable but managed to squeeze it back to a tighter fit, now the auto works fine. I replaced the dual 8uF with two separate ones (22uF) and fitted these underneath the chassis. Job done, works well, Thanks everyone for your input. Best wishes Ken |
