I have a BSR P128R (which looks very much like the P170 in your pix). The problem I have is an old chestnut, how to get the platter off. The unit is in a Pye radiogram of uncertain age, electronics all OK, but the usual problems i.e. slow speed (no doubt the idler glazed), speed change stuck and obviously needs a bit of help once I get the platter off.
It seems to be plastic or thin metal, and I am loath to prise it off. What is the usual treatment? I was thinking of using a bit of hot air plus WD. All advice gladly received, don't want to break it since all else is in good condition. David |

yes by all measn use heat to soften the dried up grease in the shaft, I normally use a 15 or 25 watt soldering iron inside the shaft having removed the centre stub, if your going to use WD40 then aim it very carefully at the top of the shaft, leave the soldering iron in the shaft whilst gently turning the platter back and forth also gently pulling the platter up as you do this.
Once you have the platter off you will probably need to the same treatment for the automatic gear, remove the circlip that holds it on, heat the casting next to the pivot whilst again turning the gear and pulling it upwards. Once you have this off you will might need to do the same for the actuating levers on the auto gear wheel, follow the same procedure. When all is don't clean up all surfaces with white spirit, the actuating levers use a little drop of light machine oil on the shaft, the auto gear use grease on the pivot and the same for the platter shaft. Get all that done and you are about half way there ![]() Gary |

I think you may be referring to the centre disk.If you carefully insert pin between disk and rubber platter and lever it will flip off to reveal circlip.
