How to service/repair/replace the height adjustment on a technics 1200/1210 MK 2 turntable part 1

This is a video showing you how you can serves/repair/replace the height adjustment on your technics SL 1200/1210 MK II.
This is quite a simple process and one that will save you money I went to my local electronics repair shop and asked for a quote and they said £60 to un-seize it and £80 to replace it thats before parts, thats just labor !!!!!!! I said wow thats steep and he said yeah well I got to strip the whole tone-arm apart it could take hours. What like 30 minutes, OH I GET IT yeah that sort of hours YEAH take the rubber bottom off stand around and scratch your balls and talk bollocks 30 minutes take out the tone arm assembly than take a break and drink tea for a further hour than replace the adjusting ring and stand around and scratch your balls and talk bullock for another half hour put it all back together and charge me £150, BARGAIN!!!!!
Sorry about the rant there, this is what pisses me off and the reason I do the videos because Im sorry but thats a rip of it absolute daylight robbery!
Information.
If you use WD40 to clean the threads it may be easier to spray the Wd40 into a cloth and wipe the threads rather than spraying Wd40 directly onto the threads in order not to coat everything with oil.
When you screw the adjusting ring back on (the bit you turn to heighten or lower the tone-arm) once you have screwed it all the way on you have to turn it back on its self (loosen it again) until it hits 0, but if you have to turn it to far back E.G more than half a turn the threads may not be lined up right and you may have to take it off again to realign the threads again.
Use a cotton bud or a small paint brush to apply the grease, it will be easier and get more grease into the threads without much effort.
