content: I've seen quite a number of part numbers that all seem to be for about the same thing, an 8x2mm feeder:"0402"KW1-M1300-000KW1-M1300-110KW1-M1300-020KW1-M1300-030"0201"KW1-M1500-000KW1-M1500-110KW1-M1500-021KW1-M1500-030All I can tell is that the M1300s seem to have blue handles and the M1500s seem to have green handles. I don't understand what the difference between a feeder for 0402 and 0201 should be given they're both 2mm pitch tapes. Also, what are the 3 numbers at the end for?As some background, I got stuck trying to make some 8x4mm feeders that don't have the leaf spring work for some tiny components. I've found that if I transplant a leaf spring from an 8x2 to the 8x4 that there's no trouble at all (with out it it's flinging parts out of the pockets). I'm wondering if the last 3 digits have something to do with options (like a spring) and whether M1300/M1500 actually is different in some way that optimizes for the different size parts.

content: The 2mm feeders come in normal accuracy and high accuracy.

content: As mentioned before, one is for 0402 components and one is for 0201 components and it definitely does make a difference.Normally, the last three digits indicate a version or a revision, so that won't matter much overall. There are plenty of subtle differences between the 1300 and 1500, mostly in the tape guide and shutter plate. Even when sitting next to each other you can see the 1300 has a wider tape cover plate opening than the 1500.See attachments.

content: Accu-Sembly: wow, that is exactly the kind of response I was looking for. A few follow ups if you'd be so kind as to answer:1. Where do you get those pictures from? Those are exactly the kind of assembly drawings I've been looking for and can't seem to find.2. Do you have an assembly drawing for a CLY-84 (KW1-M1100-030)? I'm curious if the spring just doesn't come standard with the CL-84. For context, the part I'm having trouble with at the moment is a CSD17484F4, a 0.6 x 1.0 x 0.2 mm part in an 8x4 tape.3. I assume the 0201 style feeder might have too small a cutout for 0402 parts to fit through? I.e. you might be able to get away with an 0402 feeder if the stars align, but might not be able to get 0402s out of an 0201 feeder if the stars don't align.Thanks again for your help, your reply was excellent!

content: P.S. I forgot to ask, but do you know a good source for the KW1-M134T-001 spring? I've tried getting a quote from a few for 50 quantity but nobody wants to reply.

content: Happy to help.1. When you work with these machines long enough, you end up collecting quite a bit of very helpful literature. Some of it proprietary and I'm not honestly sure what the limits are, but the CL style feeder is enough generations behind that I think posting these particular pages is pretty safe. It's not my intention to step on any toes in the industry.2. See attached.3. You are 100% on the right track, though you will want access to a feeder calibration station by the end of this project. I have a couple custom feeders that do exactly what you are thinking. In fact, look at the photo I linked above to demonstrate the differences in cover plates. By pure luck, the second from the left (with the black tape installed in it) is one of those feeders I made exactly for the type of component you are struggling with. See the gear teeth? That's a fine pitch 0201 feeder made to advance 8mm. You can even assess the clearance of the tape pocket on the smaller cover plate. So, you can totally do what you're already thinking, and any company would be lucky to have someone with that mind set and problem solving skills.4. Try Trans-Tec for parts:https://www.trans-tec-america.com/service- They are definitely not the cheapest, but they are the best. If they can't get you what you need, I have a few third party sources I could give you.

content: Hiya, thanks for posting that last picture.I have a couple of 8mm CL feeders that have slightly bent or damaged mounting pins - they wont mount into the machine.I didn't know they are called knock pins. Now I do.Have you ever replaced these? One feeder has the pin press fit in and the other has a grub screw retaining it.The press fit one might be a problem. I think I'll have to heat the area surrounding the feeder.Interestingly, your diagram says "press fit and training required" for this part!Thanks

content: Quote from: law on June 05, 2025, 11:28:25 pmAccording to my repair notes from long ago, yes, but they were never quite the same. Those pins are so critical for function and alignment it's just not worth it IMO.

content: Yeah, Its only one with the press fit. I'll try my luck and see how I get on.Thanks again

content: Quote from: Accu-Sembly on June 05, 2025, 08:51:02 pmI could use some of those extra sources. Trans-Tec won't deal with me because it's not an actual Yamaha machine.Thanks again for all the help. These diagrams are definitely great!

content: Ah, I didn't even think to ask. Not offering any volume or regular business would also be working against you for such an inexpensive part.I would try CRM Synergies next. They have been able to track down challenging parts for us before.https://www.crmsynergies.com/contacto.asp
