Garrard sp25 mkIV

Post by rzepska » 30 Dec 2018 15:16

Hello. I have a problem with my arm. I recorded a movie to show what the problem is.

The linkage for arm positioning during shutoff is binding, likely due to old stiff lubricant.
The machine requires cleaning and re-lubing.

There is a trip lever on cam wheel that needs to move absolutely free. Usually it dries stuck on to the shaft/spindle it is on. Sometime so that is does not move at all. It it is not able to fall back in the end of the cycle this you experience happens.
I don't have any SP25's left so I am not able to take a picture for you but take the platter off and inspect the cam wheel - it is rounded triangle shape if I remember right.

Please, can you mark me in the picture for which part is it?

I marked with the arrow the shaft it is on. If it is not moving freely you may need to take off the circlip - fastener(pry with flat screw driver and be careful not to fly this away - put a piece of tape on it) and take off the trip lever(I do not remember if it has something under the cam wheel as well - inspect first); clean the shaft and lever hole(toothpick) with alcohol; re-lube with drop of sewing machine oil.

Why hasn't anyone so far addressed the real problem, located UNDERneath the chassis?

The lever moved freely but for sure I pulled it down, cleaned it and lubricated it with oil. Unfortunately, it did not help.

Dis-assembly, cleaning, and properly re-lubricating of the mechanical assemblies pictured in the upper right hand of that photo, along with those levers along the top leading to the control panel.
It's common for various parts there to become "bound up" from grease/oil that has turned to glue.
I've had to do it hundreds of times for people.

Can you recommend what grease I can use to relubricate these mechanisms?
In my spare time I will try to collect for cleaning and re-greasing. Thank you for all tips and advice.

I've always used Super Lube for grease, and Zoom Spout Turbine Oil for rotating pivots and motor bearings.

I am trying to undo the control mechanism but I have no idea how to unscrew the part marked in the picture.
