Hello all, been lurking here and there a d everywhere for quite some time, I own a 5 acre property in Central Arizona. I recently purchased what I believe to be one of the earliest "green" Yanmar YM1500D's.
I did a lot of research prior to purchasing any type of tractor (for the last year) and finally came across the right deal and had been saving for a while and pulled the trigger on this machine.
Bought it from a guy on Craigslist...previous owner said he owned the machine for "about 2 years", maintained it himself and stated "no leaks" and "low hours", both of which I knew couldn't be true with it being 40+ years old. I went and looked at it, went through all the basic functions, started it, loader up, down, curl, dump, 3 point up, down, etc... gave a once over, saw some leakage in the front knuckles, you could easily tell it had just been pressure washed, as whoever did it, missed ALL of the "under spots" that still had years of crud and goo. I negotiated a bit and loaded it up on the trailer.
I don't trust anyone that I ever buy anything used from... a habit of being burned in the past....so upon bringing the tractor home, I purchased all new fluids and filters, changed all fluids, oil, fuel, and air filters, and cleaned the suction screen (Supertech hydraulic/transmission and Delo 15/40). Flushed the radiator (too much antifreeze, and lots of rust, I know this because it overheated in about 10 minutes of driving around and playing after getting it off the trailer, which is why I think the guy I bought it from just "flipped" it and did not have it for the 2 years that he stated). He also was not familiar with most of the lever functions, PTO, diff lock, 4wd. Refilled with water only for now since I don't have to worry about it freezing.
Bonus-maybe, it came with the US version of 3 of the Hoye manuals with the 155D circled in permanent marker on the manuals...is the 1500D equivalent to the US model 155D?
Also came with a few parts on the tractor and stickers from Hoye...so at least I know somebody in it's history cared about it a little bit!
After all of that, it is running excellently, but, here are a few concerns/issues/questions.
1. Confirm that I have a "green", don't care green or red, just need to know for ordering parts.
2. Front knuckles appear to be leaking from the large seal that connects the upper/lower half, I've read this is common, any other common leaking spots in the front axles I need to worry about?
3. Out of all of the YM1500D pictures on the internet, I have seen 2, that do not have the twist knob between the legs, mine makes this 3 (which is why I think it is one of the earliest models made)?
4. Prior to doing some research AFTER I made a mistake that I didn't know that I had made.... the 3 point lever has a nut and bolt that friction holds it in place, I did not realize that lever needed to be moved forward just a bit to put it in "neutral" once it was raised, I then operated the loader with the 3 point lever "locked" in the up position. I don't know how long or how many times I did this, but I was moving dirt around for about 45 minutes before the 3ph and loader quit working altogether. I shut the machine down and began inspecting, I had no idea what happened or that I caused it to happen at the time. I noticed some smoke coming from under the hood and saw it was coming from the hydraulic pump, it was HOT. I let it sit there for about 30 minutes to cool down, started doing some research, went back out and all was well again, for about 10 minutes before it happened again (I still didn't know, I was the cause of this yet). I parked it and shut it down and began digging through forum threads from late 90's all the way up until present.... that's when I realized that I was the problem and I caused the pump to overheat. I should note that the controls allowed the loader and 3ph to lower, but no raise, curl or dump.
This was Saturday and I haven't had a chance to do anything with it as of yet. I did check engine oil to see if it was overfull from a blown seal. between pumpkin pop and motor, but it was not, hydraulic fluid was right on full as well.
So now my question....should I continue to run it and hope that I didn't screw anything up internally? Or should I pull the pump out and replace the oringsand check they key just in case?
5. Prior to making my mistake when I was only operating the loader with the 3ph down, there was some screaching noises coming from the hydraulics somewhere, but only at the limits, end of curl, end of dump, and top height of loader, are my lines sucking air? High pressure or suction line? I don't know. this happened before and after changing hydraulic fluid and cleaning suction screen. I plan on taking ALL the the horses off and blowing them out as a precaution. Anything else I should do? (I do not have a pressure gauge to test system). There is no noise in the hydraulic system when operating the 3ph.
6. The suction screen appears to be the one Hoye sells from the pic on the website, it wasn't completely caked with crud, but it definitely needed cleaned... what I didn't do, was pay attention to what direction the screen came out. One end of the screen has the metal mesh covering the end, the other end does not, and doesn't appear to have any marks on the housing that it ever did.... are they directional? I put the screen in with the covered mesh end in facing the suction hose.
7. Can anyone identify my loader control valve? PN# 156B2303 Only thing I can find regarding part number is on a QCC website, but nothing else. The valve has a Power Beyond port and I would like to find the "sleeve" so I don't have to worry about me or anyone else that may operate the tractor making the same mistake I did by accidentally using both the loader and 3ph at that same time with it plumbed in series.
8. The loader appears to be homemade? Can anyone confirm that by the pics or is it a repainted and beefed up Koyker? SSB? VN? etc...there are definitely some welds that do not appear to have been done by a manufacturer.
I already have a few items in my cart on Hoye's website, but if I can confirm some things and hopefully get everything ordered in one shot, I would prefer to do it that way.
Any help is appreciated and sorry for the long post!
