Yanmar ym1602 / ym1502 lift arm guides.

[careyo63]

The YM2000 was A import rice patty tractor. Tiller! No doubt about it. The water damage showed up in several places. Lack of Maint Ect.. Had a tiller for it. I purchased a Yanmar 1400 from Fredricks. It worked much better than I expected. the small garden worked really well. My 3pt ghetto rig! worked will it last?

so probably not gonna be needed in the future for my uses.. if i get a rotary tiller, it would be a 3 point model..

in your opinion would it be something worth trying to sell / trade?

It may fit other models SCUT Yanmar tractors from that era. I wouldn't scrap it. Parts like this are an extreme rarity. Someone in the next 5 to 10 years will post a message here asking how to hook up one of these old RC tillers and need the part!

Reply #2 the L. arm anchor JPG.. My org. metric threads have finally worn out also. Looks as though that may have happened on yours also from what I can see. Sure looks that way from the steel plate.
Last time it came loose I was able remove the washer and catch the last remaining Metric threads. Been having trouble for decades keeping them tight. Esp the L. one..
This last time I had to use a Standard threaded pin.. Larger Dia. that I put a Tach weld on the Loc. nut to make sure it didn't come loose. I haven't had it come loose yet but it takes quite a few Hrs. for it to loosen up. Worst case I'll try to Heli coil insert it.

if you are going to step up the size to a helicoil, why not just put the next size metric bolt in? instead of a m10 go to a m12?

on mine, the bolts all tightened up nicely, but i dont like how thin the bracket looks. i will be taking measurements and developing a better system. most likely will make the side brackets and a back bracket all one piece such that i will have bolts going in from each side, and bolts going in from the back, which should allow a very strong bracket.

after that part is fitted, i will decide if i want to use the large bolt and nut, or if i want to use a pin for the arms to slide onto.

providing this works out the way i envision it will, pictures of the progress will be added to this thread, and if any want it, measured drawings can be shared.

i typically draw the parts i want to make in autocad, and then cut it out of heavy cardboard with my laser cutter so that i can mock up everything and ensure alignment/fitment before i spend time and energy making it out of metal.. kinda a mix of the 2 "cad"s (cardboard aided design, and computer aided design) lol

AWESOME, yes, please post images of your progress and dimensions.

AutoCAD works great. The files can be imported into FreeCAD. We can then take the flat 2D patterns into 3D, even 3D Print if needed.

On the YTOG, we have a section now for Yanmar 3D printable parts in STL and STEP files.

i am gonna be mapping out the tractor side so i can make a spacer/brace adapter anyway, maybe i should draw/model the whole part and post incase someone wanted to have one fabricated if needed..

oh and who am i kidding.... i can never bring myself to get rid of anything that might be useful in the future. i dont have problems with letting something go to someone who will use it but i have never been a fan of scrapping stuff lol

i am a member of YTOG as well, that section is in the wiki right?

i typically print the drawings to pdf with the same filename as the drawing so that it is easy to scroll through and find what you are looking for.

how would i go about submitting the files for upload?

could a folder for cad files / pdf files be made over there?

do you think the chain anchor at the beginning of this thread would be an item of interest for the list?
i actually cut that out with a drill press, a 2.5 inch hole saw, a 1.5 inch hole saw, a 3/8 drill bit and a sander..
using the drawing as a template, i marked all the holes center, drilled the 2.5 hole all the way through, and then used the 1.5 to mark radius of the 3 ends so be able to sand it and make it pretty lol..

There is a members upload folder.

You can create a sub-folder in there for the project.

Once completed, The one moderator will make a released folder out on the shared system for the project.

Now if your parts are more about cutting, forming and welding, he may make a new area on the shared system for those projects.

Today we are messing around with other 3D CAD creation. 3-inches of snow going to 7 today. Nobody wants outside.

No Metric pins. available local. I would have to order them. Fredricks most likely. I do have another US. 2000 and just so happen to have them. I didn't even have to remove tire. If it would happen on the R. which has never came loose. I'll do it the same way. Heli either way metric or standard is a still a option available. Which I'll go Standard not metric.
