Iseki Tx1300 Hydraulic woes

[LOTCP]

So I'm new to this forum and like most people I signed up because I'm having some troubles (caused by my ongoing stupidity no doubt). My TX1300 4x4 has a front end loader and has been a great tractor. I've run it for over a year now clearing blackberries, tilling, and hauling things around in the bucket. Two days ago I decided to change the oil in the gearbox because I hadn't done it since I owned it. I figured I was doing right by flipping the seat up and reading the label. Unfortunately it was in Japanese and all I could see was the number "80". Well, I thought that meant 80w gear oil. Oy. So I put gear oil in it and the next day try to use the hydraulics but it goes all stuttery and soft-like. I did a quick search and found out that the TX1300 shares fluid. So I went down to True Value and got a 5 gal. pail of Accel 303 hydraulic transmission oil. It worked all day today and after running it hard I tried the bucket (I was field mowing so I didn't touch the bucket) and holy moley, it's not even working. There is so much air in the cylinders that I can move the bucket on it's tilt axis about 1/4 of it's travel! I bled the lines both ways and it got worse! Did I toast my pump by using gear oil initially? Would higher quality oil fix this thing? I'm $70 deep in oil changes already. I looked at the part number stamped on the rim of the pump and it's GP3340A. If I did trash my pump I'd like to find one to fit on it (or if I didn't, it would be nice to have a spare). Any advice or constructive criticism would be appreciated. I read a bit about Accel oil being total crap but I'm having a hard time believing they could legally sell it if it behaves like this in an old tractor. I'm going to sit down this evening and study the forum for any clues while this post goes up.

Thanks!

Andrew

I guess I'll reply to my own thread. After searching quite a bit I found the larger tx's had screens on the suction line. I went out and pulled the banjo bolt and it had a nice long screen attached, and it was totally clogged! I soaked it in gasoline, hosed it with compressed air a lot, and now things are back to perfect. I drained the oil and sock-screened it before returning it to the case. Looks like when I changed the oil it washed enough garbage down that it clogged the filter. Crazy.

I'd still like to find spares for this little guy. The tie rod ends are shot and the tires are in rough shape. It still has the original tires on it.

Hi Andrew,

Sorry, I had responded, and then I must have not hit submit and I just found it on here. Glad to hear that you got it up and running! I have a TX1300F, and I have changed my fluids several times. The filter that you found is the only one in the system. Last year, I needed a wood splitter, and I was unsure about cutting into the hydraulic lines, because I have heard nightmares about the hydraulic pumps have very little give when it comes to sediment in the lines. I decided to keep the system sealed, and I bought a splitter with a PTO driven hydraulic pump, and it works incredible. It has tons of power, and speed. That is an option if you wanted to speed up your loader, and seal the keep the system clean. Under your radiator, there is a second PTO, and I have seen the pumps connected at that point. Are you in Oregon? We lived in Idaho, and Washington State for 10 years, before moving back here. Do you have any photos of your tractor?

The spare hydraulic pumps are expensive, but there are a few on eBay right now. This is the cheapest that I could find: Satoh Bolen Mitsubishi Iseki Hydraulic Pump | eBay

It is the original AYP OEM pump. I bought my tractor a few years ago, and it also had the original 30 year old tires on it. I put R1 AG tires on it, because we use it around the farm, and in the woods, and I really needed the extra traction. They work great. If you shop around a bit, you can find them fairly inexpensive. I had mine loaded to add extra ballast. I also have front suitcase weight, and I added a ROPS. I live in New Hampshire, and we have very hilly terrain here since we are at the base of a pretty steep mountain. The ROPS were a must, but we have a grant here that pays for them. This is my tractor with the new tires:

]NICE! So there's another PTO? It's late so I don't want to go out and look. Our TX runs a 4ft brush hog, a tiller (the original Iseki one), and we have a hole digger. I need new tires but priorities are elsewhere at the moment. Tomorrow I'm going to install a Zena 150a welder so we can do some fencing. Someday I'll restore it. I fell in love with it because it's so small and so **** tough. I rebuild TDI cars for a hobby and all my equipment/cars/etc are diesel powered. I'm new to tractors and I'm glad I'm around to learn something new about my TX. Here's my wife acting silly on ours.

Thats a great looking TX! At least your wife will drive it, mine won't. I think that it intimidates her a bit, yet she will drive our 4 wheeler around the property all day long. Did your tractor come with the loader, or did you add it later? It looks like the ones that I was looking at in Washington. I really need a loader, but they are big money. We bought our tractor for the same reason.. Perfect small size, and I agree 100% They are built like tanks. I have a Post Hole Digger, a 3 point wood splitter, a rear dirts scoop, a single plow, a carry all, a lift all, a trailer for ours. I use it almost every day in the summer, and every week in the winter on our small farm.

The front PTO might be a bit difficult to get to with the loader on, but it is behind a small panel under your radiator. It is run by the fan, but can easily power a PTO pump. You have the original rice paddy tires. They are pretty impressive! This is my first diesel, and now, I wish everything I owned was diesel.. Thanks for the photo! Below is mine with the post hole digger, and the location of the panel. I know a ton of places to get parts if you need any, and I know where they sell the TX decals if you decide to restore it someday. Most of the parts are very inexpensive. The PTO pump is one of the most expensive parts unfortunately.

I bought this from Coldwater Tractors in Washington. They've got quite a bit of old tractor imports sitting in the weeds. The loader was made for a TX1500 and they installed it. That panel is still accessible with the loader on, I might pop it off tomorrow and see if I can make a removable Zena welder bracket for it. Immediate needs on it include tie rod ends (ball joints) and tires. I really need to find tie rod ends however. I was thinking about cutting them off and welding on some VW type ends.

Your TX1300 may not have come with a front PTO. Mine didn't. See the second post on this page for further information:

Installed a Zena 150a welder in place of the original alternator today. New belt tomorrow and I'll have a portable welder! Pics to follow.

 

[LOTCP]

Not one to leave a thread hanging. The Zena didn't work very well. So I put a GM alternator on it instead. Would like to find tie rod ends and tires for it. It's been raining here too much to do anything outside and since I last post I've been out of state/country for most of the time.

LOTCP, Hello from Central Oregon. I have a TX 1500 and it was originally sold in Woodburn, Oregon. I have a front pump on my Iseki that runs the loader. It is a completely separate hydraulic system from the tractor 3 point system. I bought new front tires from Les Schwab a couple years ago. They got them over night and were quite reasonable. I could provide you with details about the front pump if you are interested.
