Default Technics SP-10 Mk.II braking system overhaul

Hi folks.

Hope somebody might be able to help with the following.

After quite a long search, I've managed to find a complete braking system for an SP-10 Mk.II on Ebay, with the added bonus of a (supposedly) working strobe light too. 70 so rather an extreme price, but it's all advertised as working, and I guess these spares are pretty rare now. It'll be nice to finally have a 'complete' deck at last, as my SP-10 had the braking system removed by its last owner.

Unfortunately the braking solenoid needs some work by the looks of it. It needs cleaning, a re-lube, and the rubber end-stop washer (part 14-4 in the service manual) isn't there.

I assume I can use a bog standard rubber washer of appropriate size there. Does anybody know the thickness of this item though, and the circumference? Also I haven't a clue what kind of grease I should use to re-lube the solenoid - any advice here would be much appreciated indeed.

Cheers,

- John

I looked through my disassembly photos to see if I could pinpoint the washer you're looking for but unfortunately came up empty. The above photos is as close as I can get to the brake solenoid. For whatever that might be worth.

Thanks for that Steve - much appreciated

Managed to find a slightly clearer photo of the whole unit, and looking/measuring the solenoid shaft the inner diameter is approx. 10mm, the outer 15mm. I shouldn't think it's too critical. Have ordered a few rubber washers and hopefully one of them will fit.

That'll be it then for my deck, though I am keeping a very interested eye on your current thrust pad adventures

OD=14mm
ID=8mm
Thickness=2mm

After many times of actuation, this type of washer can break.

I'm a bit late to this thread, came to it while doing a google search for pics as I am doing a bit of an overhaul today. John, i noticed in your photo there is a circlip missing where the brake strap connects to the solenoid. There is also one on the other side. Not sure whether you had not yet replaced it, or didn't know that there are circlips.

Regards,
Phil
