Mechanical issue with Miniscribe

[VicNor]

I kept a Miniscribe from a SE that I restored and sold off a couple of years ago. I've only got it to spin up twice - both involved that I "applied" oil (synthetic sewing machine oil and Singer super oil respecitively) to the stem of the centre spindle. Then I work it out like crazy. At first it's stiff but it improves a lot after workout. I'm don't feel that not much of the oil get's where it needs to go because of the little disk (that keeps the Pabst motor and platter package/assembly in place) is in the way.

My question: Is there a way to remove the little disk to properly lubricate the drive so it can easily spin up again? I don't wish to open up the drive and expose the platters. Or should I just go yolo and squirt some WD-40 in there to loosen up/dislodge any grime?


PS There's nothing of importance to me on this drive and I have already imaged it and copied the content - twice.

This bugger. How do I remove it? Is it possible? Do I need a special tool or is it bulted on so it's impossible? I've tried to lift it with a flat screw driver but that doesn't help.

Or is the Papst motor on the Miniscribe constructed so you can only relubricate it if you open up on the platter side the harddrive?

PS I've googled this problem and it doesn't seem like there's a known solution. If YOU think that you can help, this is your time to shine.

That looks to me like a threaded on nut, that probably requires a special spanner tool. You can use a needle nose pliers opened up to fit the notches, or maybe a lock ring type pliers. Or use a single flathead and a tool to tap/strike the flat-head to unscrew it. But since its a hard drive, I would not suggest the latter (impact maintenance) with the flat-head.

Thanks! I'll try to goto the hardware store next week to find a spanner tool that'll work.
