Can´t get this Garrard motor apart
Posted: Sat Aug 04, 2018 6:01 pm
Hello
Suddenly the spring (s?) broke and I need to take the motor apart and have a look to see what springs I need.
The screws (see photo) won´t budge. I've sprayed them over and over with penetrating oil to no avail. The motor seems to be in fine condition, no rust anywhere and it´s not worn. There´s a lot of oil and grease everywhere and I suspect the screws are stuck with oil that has hardened.
I´ve looked through older threads on stuck screws and below I´ve compiled a few tips.
My questions: can I put the entire motor in a freezer, would that help? Would it damage anything else?
Would heating the screws be a good idea - seeing as they seem to be stuck with old hardened oil?
Thanks for any further advice, I´ve never worked on a Garrard before... Snal
COMPILED TIPS:
One of the few things I've learned over the years is never to rush a stuck screw.
Just mind it daily with your favorite light oil, atf and lacquer thinner, pb blaster or whatever while you attend to other things. One day those screws will turn.-Bill.
I like to use a heat gun to help remove difficult screws. It's been some time since I disassembled a fat Victrola arm but I don't think the threads are reversed. Jerry B.
To break the friction on my old bikes, with obviously larger screws and bolts, I find that after penetrating oil, turning them IN just a few degres, like 3, breaks them free.
The bit about having a screwdriver that fits EXACTLY, and this might mean dressing it to fit with a file, is mandatory. Old British bikes have slotted screws made from hard cheddar, and I learnt it the "crying with frustration" way.
What I found was that a very good screwdriver that fits exactly is essential to getting these screws out if they are stuck. Most screwdrivers have a tapered tip, which is not what you need. You need a screwdriver with a tip that is all right angles, so it completely filles out the slot in the screw head more more torque.
