Got lucky and just bought my YUASA off Craigslist for $60! Saw your video before I restored mine, thanks! Had to create a new ratcheting detent for mine to keep the ratchet from slipping, along with replacing the two needle pins (one needle pin is used to align the ratcheting detent, and there's also pin to hold the sleeve/bushing both inplace that the main geared indexing pin rides inside. The sleeve needs proper alignment as the sleeve has a cutout section on it to expose the gear of the indexing pin for mating with the release handle's gear -- though I don't think you had to mess with the indexing "sleeve" in your video.) Overall, I had to do lots of cleaning of old dried grease. I also had to debur my locking pin around its gear area to allow it to travel more freely inside the sleeve (for which my "release handle" now readily snaps into place as soon as it aligns with the next index hole.)
One tip when tightening the main LOCKING ring/collar: keep the indexing pin FULLY RETRACTED from applying ANY pressure on the index-plate, while tightening the locking ring -- and you'll be surprised at how little (if any) you'd need to tap on the locking ring's groove with your screw driver! (I've had to disassemble/reassemble mine several times to resolve my ratching issue, and figured out the trick, since when the pin is fully retracted, you'll be able turn the ring significantly more by hand without tapping on it.) I'm thinking that, with the built in tolerances, it actually snugs up sufficiently without the need to torque it much, which is why I believe they designed that additional locking screw that mates with the coining on the outside of the ring (as a solution to holding the locking ring in place under a low torque scenario.)
Good deal, Thanks for the comment.
Got the same one recently paid 14 bucks for it. Just missing the spindle nut. Is in great shape! The vid really helped me to know how it works and the dissambley its basically the assembley reversed! Saying hi from Costa Rica! Thx
Thank you, Good deal, very useful tool.
Randy, good to see you figured out the indexing problem with the plunger. The tool looks well made.
We too are finally getting some long over due rain in southern California and hope it will continue.
enjoyed following along!
Thank you for stopping in.
While doing a little pre-purchase researching for a Hardinge HLV I find this - Just the kind of video I like to watch. Excellent information, thank-you for the vid.
Thank you Joe for coming by the shop.
that appears to be a well thought out design on that indexer, good fix Randy!
Thanks Brian for watching.
You should do a disassembly video.
Nice use of a snap on screw driver! I liked it! You missed an opportunity to show the Pierre, Phil,and Robert hammer in action. Good job, good video! Enjoyed it much.
You should see the tip of that screwdriver. I love there hammer and use it all the time now.
Hi Randy, what a superbly made indexer! Agree with Brian re applying grease, lets face it, it's much easier to remove grease than rust. Kindest regards. Joe.
Nice handy tool, good video on how it works/assembly
Thank you Chuck for the visit.
Have to chuckle seeing those mitts trying to handle those dang tiny pieces. Same issue here. I use lots of forceps & similar tools for small hardware. Darn nice indexer.
Sometimes a bit difficult.
That is a very nice tool. I can see where it could be all kinds of handy.
Thank you Harold for stopping in.
I need to take mine apart, the straight knurling is properly called coining.
Thank you for the info.
That indexing plate is cool with the set screw idea. That's a very nicely designed and machined unit.... way better than my 'cheapy' Chinese one. Looks like some TLC and lube gets a nice fix.
Hope you survive the expected excess of weather and rain!
Thanks Chris for stopping in. Really wet here. Good thing.
That was a fun video to watch. Love it when a plan comes together.
Yes thank you Ken. I had to do this in the middle of the Rotary Broach project to make the broaches.
There are so many variations of these collet indexers. I have a Japanese "NEWS" brand indexer, which seems to be nearly identical to a Yuasa, which makes sense since they're both Japanese. Yours has three screws on the grub retainer collar, mine has four. Other than that, they look identical. Same castings.
Rust protection benefits from the grease likely outweigh any sticky drawbacks.
No real rust problems here, but I do not do alot of indexing and it might sit a bit. Thanks Brian.
Nice indexer. It looks identical to mine which is a “yussa “. Mine isn’t in great shape, and missing a few parts like the little locking piece that stops the knurled round nut from loosening, the metal ring that serves as a stop for the plunger screws, the thread protector and the ratcheting handle. I’m sure you would never find parts, but looks like they could all be made. But with your video at least I know how to take it all apart. Keep the videos coming! JB San Diego
Thank you JB. I think you are correct. Good project, very handy unit. Stay safe down there.
Nice Indexer Randy.
Thanks for the Video
Thanks Phil.
Thanks for sharing Randy!
Do you have any idea who made this indexer? My chinese one looks pretty much the same but is in a few details different, for example is my ratchet ring not split, it has to be assembled together with the spindle.
Thank you Stefan, not sure who made it no man. mark. Well made and in great shape.
I should do some scraping on it to make it perfect.
I have almost the same one made by Hardinge here in the states. Im not sure if that helps or you may already know that. Sorry I cant help on the chinese copy manufacturer.
Randy, you mentioned it possibly being sticky due to the grease. Try some NLGI .5 or 1 grease instead of the common 2. I keep a tube of engine assembly grease just for items like this, and I think what I have is Lubriplate and I believe that it is NLGI .5. Comes in handy from time to time.
Yep i might try some Lubriplate, i have some of that.
Excellent video!!!!
Do you think it might be a better idea to use a machine oil rather than grease? Im a noob but I have found with tight tolerances machine oil allows the lubrication needed. Also I have learned the hard way in some cases that tacky grease holds foreign materials rather than providing low friction for them to evacuate; Sometimes causing marring etc, especially with harder chips.
Coming from the automotive workd I put some red n tacky on the spindle in my bridgeport and i couldnt even turn it by hand 😅.
Not saying you are right or wrong just throwing it out there.
Thank you.
Nice video
Thank you Dale. Hey we are getting some rain.
Nice indexer, Randy. Looks like it is pretty straightforward to work on and use.
Is there any sort of spindle lock to hold it securely once you have indexed it? I look forward to seeing you use it.
Stay dry but enjoy the rain.
Joe
The pin. it is very solid.
Hi Randy !
Nice indexer but what are the idea behind the screws in the indexing holes ?
Maybe something to do with the preset index pattern or ... ??
As you saw yourself they COULD be the source to a problem if the indexing pin is NOT allowed to go fare enough in the hole !
One can't even take them out because of the cover ring - it looks like a stuped design with these screws ... what's the idea ?
You back out the screws where you want it to lock in and stop. You have 24 possible stop positions.
Thank you Keld, for watchings.
Hi Randy,
This looks like a good quality indexer, so far I got almost everything but an indexer, I'm still on the watch... ;)
Hope you get loads of snow or rain California NEEDS it, is your work season still on or are you on break for Winter....?
Cheers, Pierre
I do not know the brand but it is quality made. Lots of rain 9.2 in in the last 10 days. The weather is giving us a bit of a break from work so i am getting some shop time.
Wind and rain here too...allot of wind blowing my cat door open with a bang-bang! Thanks for the water wishes Pierre, that's very kind of you.
Hi Chuck,
Last year The wife and I went to California first to the Bash and then spent 2 weeks touring around, even stopped at Randy's, we found very discouraging the drought where everything is so dry and the future is also uncertain for agriculture mostly... Since water is life hope you get much more to replenish the underground reserve...
Hey Randy, is that a Phaze II indexer? I have one to clean also. Thanks for the video, it will help me later when I get to mine.
i do not know the man. no markings. but it may be.
Hey Randy went back into the archives. I got a HV-0 Hardinge (little brother to this one I think). The one I got is a 20 pin indexer. Thoughts on making a 24 pin like yours? I think the ring would be about the only needed change and maybe the locking pin diameter. I think it’s worth a try anyway.
Sounds like a plan Dan. More options. Merry Christmas.
d00d that transition from the intro music to the actual video is so harsh .. the song just starts kickin and then smashcut to the video. You should fade the music out or something hahahah.
Thanks for another interesting video, as always!
I will have to fix that.
Well done how to use, how to put it together.
Thank you Bob.
