Thanks and even a bigger thanks for all the manuals you have come up with and shared. You deserve a raise! :thumbsup:

- Yanmar YM2610 ■YANMAR GURU■ EXTRAORDINAIRE
Clemsonfor, by 'default' I became the owner over there.
The original owner left the Yahoo group he started. The only remaining moderator keep it going for almost 20 years. He's been retired for well over 10 years. He didn't have the energy anymore to keep it going, yet alone a mass migration of EVERYTHING in the FILES, PHOTOS, LINKS and DATABASE with the IT admin setup on the new site. Here is a nice writeup with the history of the group. I'm sure it's not 100% in details. It's the best I could piece together and the information passed on.
A little history of our Yanmar Tractor Owners Yahoo Group.
For your YM2000, there are a few good manuals for the machine.
BTW, today at MIDNIGHT, Yahoo Groups will be fully DELETED from the internet. Doug had no ability as a moderator to turn things off nor delete the group on Yahoo, so it was left on auto-pilot. I've sent out notices in the past week. We picked up an additional 14 members in 3 days.
All the prior messages from Yahoo Groups & GeoCities were archived using the PGO-4 software. About 95% of the messages are fully intact. However, all the message attachments didn't come over. Thus, the reason why the PHOTOS folder of 675-ish Mb was also backed up too.
Yahoo Groups had over 4 Yanmar groups. We archived all of them to retain the history. Additionally we assisted to save 3 other tractor groups too. Mitsubishi-Satoh, Struck Machines, and Gray Market Tractors.
Since the migration, repairing all the broken old links, finding new ones, making the DATABASE into a usable WIKI page, community members scanning and donating manuals or pointing where manuals are located on the web or Karl in the Czech Republic with his operations manuals or the massive holy grail of manuals from an abandon 2007 Zen-noh Japanese website, the group is so much strong that it ever had been. In fact, the monthly total messages now are in the hundreds like it was in the heyday of 2005 on Yahoo Groups.
The group has retaining it's true identity via it's original motto coined by Jay Brown, "A valuable source for owners of Yanmar tractors."
Jay Brown is retired himself. He has no interest in Yanmars that I'm aware of. Using the WayBackMachine, I had found all the good info of his Yanmar operations. Likewise for RCO, LMTC, and many others. It's all part of our tractor history and the group.
Much work over the last year kept everyone in the Yanmar community busy. The list of people stepping up to assist is widely large. So, I can not take the credit other than keeping things organized.
Our group is not a replacement for the existing tractor forums with a Yanmar sub-forum. We are a compliment to these forums.

Wow that was a lot of info. I need to click over there when I have time to read. I knew there was a Yahoo group that had largely become defunct/ idle. Never went to it. The manuals are of interest to me. I need to grab those files. I also have a 186 but I believe I have the important ones from California. I have them saved in email.

I clicked your group history link. It's pretty funny I'm sitting here reading that and I am just 30 minutes up the road from Easly SC here in Greenville.

You guessed it!
The rollpin (part 7 in post #4 above) that attaches the arm to the lift-lever was broken.
The safety wire in place of an inner rollpin, isn't in the parts manual.
I might not be the first person to repair this - there were tiny remnants of two colors of RTV gasket.
This assembly pushes/pulls the plunger that goes into part 1 in post #16.
Now I need to figure out how to force in the replacement outer and inner rollpins, working down in this cavity. Maybe needle-nose ViseGrip pliers will fit in there.

And in case someone else ever has to make this repair, here's a caution I saw in the Service Manual:
The drop rate control, the little T on the right side of the transmission, pushes against a plunger on the right side of this removable top assembly. The T lever stays in the transmission casting while the plunger comes out with this top assembly. The Manual cautions to not drop the plunger down into the gears when lifting off the top cover.
I had screwed the control in all the way to push the plunger in, then had to unscrew it for clearance to lift the top off. The plunger was still all the way in but it was oily and easily could have fallen if the top were tipped while removing it. Be careful!

Yanmar must have a specialty tool to get that spring pin (rollpin) in, to attach the external lift lever's shaft to the driver for the internal hydraulic valve. This was a nightmare. (See parts 6, 7 in post #14 above).
The not-visible hole in the lever's shaft has to stay perfectly aligned with the hole in the block that the spring pin starts in. With the lever swinging free off the side of the workbench it was a miracle that the holes stayed in alignment as I forced the spring pin in.
This took extreme force. There isn't room to hammer on the spring pin so it has to be driven in by something similar to a screw clamp.
I used various flat objects to pry the pin in, being careful to not twist the block relative to the hidden hole in the lever. First I used the square top of a carpenter's nail punch, the only thing small enough to fit between the end of the spring pin and the cover casting. Soon more leverage was needed so I pried with a chisel 12 inches long. Finally, after the tip of the spring pin had passed into the lever' hole, extreme force was needed. I got a couple of old rusty jumbo chisels from the junk box in the barn and had to use them like expansion pliers, forced by Vise-grip pliers.
Thankfully this didn't bend the shaft that the pin went into. It seems like it might have.
Putting the second, 3mm spring pin inside the 5mm required backing beyond the first pin so the 3mm pin didn't drive both out the far side.
Mission accomplished. I added safety wire as shown in the Service Manual, and that part of the project is complete. When the rain lets up I'll go out and do the (easy) reassembly of that cover back onto the transmission.
And thanks to Aaron (Hoye) for having the spring pins that I couldn't find anywhere, and even the original paper gasket for the cover.
