Default I wonder how long this has been in the loft?

I couldn't resist this old Garrard model T Mk2 at my local auction today. The 2 pin mains plug was attached. Took me a few seconds to recall how these worked - for the electrician in a real hurry?! Promising old thing - the motor turns nice and quietly. But that's as far as I got tonight - I left the necessary tools elsewhere.

That platter mat looks in good nick. There'll be an old Garrard GC2 or GC8 mono crystal cartridge in that headshell I expect. Be careful when twisting that star shaped speed selector, these can seize. This unit comes from 1956-58.

They're a sort of wander plug in stereo or should that be on steroids?

It is in surprisingly good nick for one of these - as is the fabric covered flex - must have been stored well. GC8 cart - untried as yet - the RF co-ax lead (I rather like them as interconnects) is in a bit of a state (screen pinch clamp upside down for example!). And those were the tools I didn't have to hand. Yes the speed selector is very stiff - I shall proceed with care.

Indeed the speed control is very VERY stiff. I have dismantled it as far as in the photo. I assume there is some sort of selector mechanism in the casting which aligns the idler with the different steps on the spindle - but I can't see any obvious way of getting it apart - advice please.

Hi Roj, that is the same as used in the 4HF. It's the old grease problem again.
Heat it up and the cast part slides off the spindle.
Take note of the orientation of the parts for re assembly.

David.

It's a complete dismantling job, Roger, as in my thread earlier this year on the "Home made record player", if you remember reading it - especially the second page:-
https://www.vintage-radio.net/forum/...=145791&page=2

I thought I'd posted all the pictures of the deck in a dismantled state on that thread, but it seems I didn't, so here's a couple more to add to the ones from that thread:-

Thanks David and Frank - I thought that should be the case. I have heated it up quite extensively but as yet to no avail....but I am fully aware of the araldite like qualities of Garrard grease - and I shall have another go!

Thinking back, I probably used some of the dreaded WD40 to get things moving then gently turned it back and forth until it was possible to slide it off.

I know it was atleast 10 years ago as I didn't have a digital camera then and did a drawing of the alignment.

A petrol-based solvent such as Plus-gas or any petrol lighter fluid will be more effective than WD40 at freeing hardened grease.

Or do it outdoors with the real stuff- leave the fags indoors, though

You'll need an old washing up bowl, a tatty old coffee tin, a paint brush that's seen (much) better days and some oily rags to do a professional job, dilettantes can go for the clean unused versions.

They can be a real pain, on a similar deck I lost patience and held a small blow torch on the pin for some time. After a while it just fell apart

A long soaking in car engine oil is quite a good way of getting hardened grease off.
It contains an additive that keeps internal engine components clean and it also works on hardened grease.

Default Re: I wonder how long this has been in the loft?

I agree that if it's very bad, then careful use of a blowlamp is the only way. I had to resort to the gas blowlamp on mine - it was the only way, and that's why the whole assembly had to be removed from the deck first. Be VERY careful with the heat and just 'waft' the flame around it as the main part is made from 'monkey metal', and we all know what that's like!

Take careful note of how the idler wheel height is set, and that the grub screw should be tight and the spindle itself should be free to turn in its bearing in the casting - this will also probably be solid and needing heat to free it off.

On the other hand, if all parts of the assembly are moving slightly, then perseverance with solvent and oil as advised by others may work - but you'll still have to get some lubrication onto that internal 'roller' and stepped casting to get smooth speed changes.

Old-type automatic-transmission-fluid [ATF] is even better, because it has higher 'detergency' than engine-oil. It's also thinner, so it creeps into difficult places faster and more-thoroughly.

[I have an AR88 tuning-gearbox pickling in a bucket of old ATF as I speak]

I use the gas hob, always works for me, make sure you use oven gloves and also make sure the missus isn't around.

Thank you folks for the increasingly extreme remedies !! It's OK - I have become aware that these are necessary with old Garrards. Michael - yours reminded me of my childhood - my old dad used to perform really intricate electronic repairs to valve equipment with a very clunky old, once-upon-a-time-electric soldering iron he would heat up with a gas ring
