Victor II Speed Control Issue

[pellicano1]

Hey guys. Having an issue with the speed knob to the speed arm. Appears the knob is around 1" too short of hitting the speed arm where it should be. I tried setting the speed ring against the governor disc and moving the arm in place but the ring goes back to its original place. I know i've done this on newer machines with success. Is there a way to adjust this? The speed knob is around 1 ¾" long. I dont see any set screws for the arm. Really odd! Any help would be great!

Somewhere behind the finger that goes from the rod to the ring there must be a collar with a set screw (square head probably) that you have to adjust to get the ring with the leather pads closer to the governor disk, supposed the governor is properly adjusted. In your photo it cannot be seen, it would be located in that difficult area behind the finger. That screw adjusts the position of the finger respective to the rod, and its angle.
The finger is double, at both sides of the ring? Then it's more like a yoke with two fingers at both sides. Not easy to adjust... for there is also that spring coil tensioning the yoke backwards, pulling it away from the governor disk. I don't know this arrangement very well,bbut I suspect must be similar to the simpler one finger version from smaller motors of this type.

Yes there is. I thought that screw just moved the collar left and right to avoid the springs from hitting it. The governor is set perfectly. I will try this. Thanks!

No the set screw also applies tension (coil spring) to the pitch control rod. By loosing it you have now removed that tension and the rod has dropped. This is why your pitch adjustor is now too short.
It is tricky to keep the yolk (ring with two leather pads) centered and the rod up and under tension.
Good luck.

It's in a really bad spot. The screw. Gonna be a challenge for sure loosening it up.

And this is what I'm dealing with.

Not the best condition but usable. You will have to reach the screw between gov weights/springs gap. a long skinny driver is needed. You will have to hold the rod up to the board and center the yolk while pushing the yolk toward the friction disc.....then tighten the screw. May take a few try's to get it where you need to be.

Also, don't over tighten the set screw. it will grab the rod. you do not want to break the slot.

These adjusting screws are a bit of nightmare, they're in a complex area, there's the spring applying tension, etc be patient. .

Welp guys I got it! It wasnt as bad as I thought! Took a few tried to get it right! Now I noticed a bent spindle and the governor gear is seized up haha. This Victor II restore has been a nightmare! But I currently have the governor soaking in Mouse Milk!

Thanks everyone!

Oh, and here is the video to the Mouse Milk soak haha: https://youtu.be/zc4i9Qj0E38

It is good to clean it, but the seizure could happen due to misadjustments. These thick teeth gears must be well aligned and with minimum end play. You should also check the governor brass bearings, they tend to wear out, and this makes the axis to be misaligned and then the motor jams. These bearings must have no lateral play (perpendicular to the axis) and only a bit of end play parallel to the axis. The bull gear meshing with the spindle must also be revised and adjusted. The spring axis where the bull gear is rotating must have but a little end play. These motors used to have some washers in the spring arbor to adjust that end play. If the bull gear moves laterally and doesn't mesh perfectly with the worm in the spindle can also cause motor jamming. Equally, a spindle bearing wearing, mostly at the upper motor plate bearing (a simple hole) can cause the spindle to have some lateral (perpendicular) play, and this causes misalignment between the spindle worm gear and the bull gear, another cause of jamming or motor running unsteady.
