HMV 511, the machine that made me break my promise

[Inigo]

Superbe!

Congratulations on your latest acquisition! I hope you enjoy your HMV 511 as much as I enjoy mine, which I acquired in 2010. Like yours, mine has the repurposed HMV 510 cabinet which although interesting, is not quite as convenient as the later version when you need to service the motor!

Inigo, AZ, thanks for the greetings
And AZ, yes...the motor is unconviently placed, even if the motor board is interesting. I will ask for an extra hand when reinstalling the motor, someone that can hold the motor with a pliers in the spindle, while I am myself fastening the nuts from the downside.

I am servicing the 34 motor for the 511, and during the strenous work today, I accindentally mixed the two spring barrels...
I had the barrels in two different buckets from the start, but then it started to rain over my outdoor table where I was working, and when carrying everything indoors, I mixed the barrels.
Does someone remember what barrel go to the right, next to the winding handle?
I cross my fingers that someone remember this , or in their head can reason out which barrel should go to the right, close to the winding handle...

[Inigo]

I think it's the one in the left side. Just think in the winding small gear rotation direction, then the next ( second gear) goes directly to the center arbor of the first spring, which rotates counter clockwise when seen from the winding crank side; so the first external spring clamp must be... better seen than explained:

The barrels can be placed with the lid to either side, although you'll see the correct placing in the oiling diagram. But the two barrels are not interchangeable: one goes in reverse to the other.

Thank you Inigo, I was able to place it right later on today, after getting an idea. There are several 32 motor services shown on Youtube, and one showed the barrel open with all the old grease inside, but I was able to see the direction of the spring, the spring that would be barrel number 1 from the winding handle side, on the 34 motor.
Thank you for answering and even uploading the photos, they can hopefully too be used if anyone else get into the same trouble.

I finsihed the service of the 34 motor this evening, it is quite a task really to remove and re install these springs. Luckily purified kerosene worked very well on the old grease, and it saved my hands for a lot of stress.

Now it is soon time to reinstall the motor, I will only wait to get someone to help to hold the spindle with a pliers while I fasten the nuts under the motor board, the motor board is not possible to remove on this model.

You can help yourself by placing the motor and shoring it under the spring barrels with a big ball of paper or clothes, wood stumps or whatever you may have at hand, to help taking the weight of the motor while you install the bolts and nuts. You really need only to pre-install two of them with a few turns of the nuts to allow the motor stand hanging from the board, then remove the shoring and continue installing the bolts and tightening them.
Or you may use strings attached to two opposite booting holes, to lift the motor against the board from underneath, then bolting the other two free bolts, and then remove the strings and bolt the other two ...

Here we can see the inside of the HMV 511, it is quite a challenge to re install the motor, both because the motor is very heavy, and the horn take up much room in there. I needed help to get it out, someone had to hold the screws on top of the motor board, while I tried to find the nuts deep inside the dark comparment with a pliers. Also, there is always the risk of damaging the speed indicator if the motors crashes in there, since the speed indicator is a delicate part of the motor.
Putting clothes is not really an option, they would all be ruined because of the grease and oil. Paper..well..maybe, but really the challenge is to balance the motor and hold its weight while fastening the two first nuts. Wood, I will avoid that too, since if the motor crashes down while trying to install it, the delicate parts may be ruined.
I think I will wait for someone to hold the spindle, and even gently support the motor from the downside while I try to fasten the two first nuts.
I will have a closer look at it today, if it feel I can do it safely alone, I may try, if I feel there is a risk of ruining something, I will wait a day or two to get help from my son.

I see... the side is so vast, deep and large... And yes, the delicate axis of the speed indicator, which must enter through the tiny hole in the motorboard... Anyway, this is kind of a design failure, for a detachable motorboard is a desirable feature.

This is probably a crazy idea, since I have never seen a machine like this: Is it possible to install the motor with the cabinet turned upside down, so you are not fighting gravity? They must have had some trick at the factory...
