VM 45 Adapter Repair

[Hi-Fi-Mogul]

Hello everyone,
I've seen a few posts somewhere about
dis-assembly and cleaning of the VM adapters.
I could not locate any info, though, on searching.

Does anyone have experience in doing this ?
And would you post a "How-to" on the forum ?

Thank you.

Mogul, I have never attempted 45 adaptor repair, but if it's a VM, chances are Gary at VM has something on how to do it. Send him an email and see what he says.

Hi Bill,
I had not thought of V of Music.
I'll give Gary a holler.

I have the exploded view of those adapters, I just
never had an idea how to start the dis-assembly.

I'm sure I chunked a few out over the years that
didn't function. I don't want to do that anymore.

Please let us know what you find out. I'm interested, and I'm sure others are to.

Here's what I found out from a nice guy on another
forum, who I posted the 45 adapter exploded view for.
He was successful, and I asked him to post instructions.

His response:

V-M 45 Adapter Dis-assembly for Cleaning:

"The first thing is to very carefully remove the star retaining ring on the bottom, which is #130 in the diagram.

Use one hand to relieve the spring pressure on it by pulling up (or down depending on your view) on the lower third of the adapter (127).

With the other hand, use a small screwdriver to slightly pry up the washer tabs, working your way around the circumference.

Don't actually bend these tabs--you just want to pry them back a tiny amount so the ring can slide up and off.

After the ring is off, you'll be able to pull off that bottom third of the adapter.
Be careful not to lose the the paper washer (126); it will be hidden in the grease on that end of 127.

Next, unscrew 125 (x2) and separate 124 from 131, i.e. the other two thirds of the adapter.

My photo shows how 119 through 123 should be installed, though I recommend taking a photo yourself before taking them out.

Watch out: There are four small springs holding everything together, and it's easy to lose one.
I cleaned everything in this section with isopropyl, especially 121 and the little well that its shaft rests in.
No lube here IMO.
I tried a tiny bit on the shaft of 121 and that created too much friction for it to swing freely.

The only areas I applied some grease to (after cleaning off the old) was at the contact points between 124 and 127.
Thoroughly clean the paper washer (126) too.

Otherwise, it's reassembly in reverse order.

The star retaining ring (130) will need to be pushed back on until it seats in the original position."

That is great information, and actually sounds quite painless. Thanks Mogul for going the extra mile and sharing your findings.

Perhaps posting this information in "Getting Started" might be helpful to someone. Thanks, Mr. Mogul for sharing this.

Good luck.
I attempted a repair on one from an RCA RP-205 (same as the VM adapters) and the red plastic top exploded due to brittle, old plastic.
I saved all the guts from it so let me know if you lose any internal parts. I will be be happy to send them to you n/c.

Thanks everyone for the positive feedback.

I've posted this over in "Getting Started".

Gary, I'll keep your offer in mind, if I lose any
parts.
I probably won't tackle one of these for awhile,
but I hope it's a fun experience (read successful).
