PM1030 Change Gear Adjustment (noisy)

Thanks you - yes I got that from the manual. What I was confused about was how to take up end float without adding friction between the washer and gear.
 
I just turned the gears by hand (chuck), tightened till snug and then locked it down. My washer (the thick one) spins with the gear(s) and I have virtually no end play. Don't remember if this was in the manual, there are also different thickness washers in the change gear kit, and depending on the setup, these get swapped around to keep correct clearances.
So how much end float are we talking?

I have a 1022 (same headstock as yours) that howls like a uh, uh, uh, howler monkey when I set the gears too tight. You need to experiment with backlash. From your picture it looks way too tight. I remove the cover safety prong and plug it in so that I can test without removing the cover 10 times, you should not do that because it is unsafe Flustered. My lathe needs quite a bit of backlash to run quietly. The gears will also need to wear in a little bit.

Agreed, I followed your same process and mine runs reasonably quiet.

Any gear with a rough finish will need to wear in. IMG_3227.JPG
These are not precision gears.

I have never dealt with gears like that, all the ones I set up are finished.
 
Just as a data comparison point, my PM 1022 runs at 58 dB @ 1000 RPM, so about the level of conversation (measured at operator position). For me, 2 thickness of paper between the gears, engage and tighten for does the trick for setting backlash. Of course change gears will be louder since they are only used if I don't have a large die and not completely run in. I know it says to oil the gears, but I used a quality NLGI #2 grease which helped as well.
 
The gears on my 13x40 are pretty loud. Someone suggested using Open Gear Lube and it helps quiet them down.

My 1022 is rather noisy also. I messed around with it quite a bit when I bought, adjusting gear mesh and clearance. The lathe has either gotten quieter or I have gotten used to it. :dunno:
I agree that there could be a better way, and an oilite bushing of some sort may help. As others have pointed out, straight cut gears, running dry, are rather noisy.
