Loader valve difficulty

284 International · Dec 25, 2010

Success! After struggling some to remove the hoses from the valve, I got the spool out. It came out in a straightforward fashion: Pull the cap on the opposite end from the lever, and, after unpinning the lever, pull the spool out. It has a spring on one end, retained by a bolt and washers on the spool and bolt head ends.

As you can see by the attached photograph, the spring was filthy with a tar-like crud, and inside the cap the crud had congealed into a crusted layer of carbon. It looked and felt just like the crust in the bottom of an oven if pie boils over. I gently scraped everything as clean as possible with a rifle brush, then dunked it into my ultrasonic cleaner. I ran it all for a 6 minute cycle in warm mineral spirits, and everything came out relatively sparkling. I reassembled it all, and now the valve works fine! Now if I could only make the motor run properly....That will be another thread, find it here: YM240 smokes heavily, lacks power - TractorByNet.com

Thanks for all your help.

I'm glad to hear that was easy to fix - basically doing the maintenance that had been neglected for a couple of decades.

My YM240 had several gotchas like that when I bought it. A month of tinkering got it back to decent condition. The primary problem in my case was it contained ancient fuel that would hardly burn. I suspect it was parked 10 years. The short-term second owner burned up and replaced the starter, buggered the clutch safety switch and the ignition switch, discarded the whole fuel filter assembly, put a 'reconditioned' battery in that was worthless, and had done other ineffective butchering without resolving this simple underlying problem. After I spent a couple hundred dollars to get back to stock condition and do a major maintenance cycle including fresh fuel, it became the nice tractor that Yanmar intended. (Well except for the weathered paint!)

I'll go look at your other thread now.

As you said, California, it appears that I need to do some of the basic maintenance and service that should have been done every couple hundred hours. I've found some other sorts of farm-expedient repairs or "service" jobs now that I've looked more closely and know what to look for. I'm tempted to start a thread on a list of all the "don't" or what to look out for when buying a used tractor. I don't want it to seem like I know what I'm talking about, though, so will document and record my experiences as I go, just in case.

I should have known better than to take someone's partly disassembled used tractor, so it's all my fault. For what it's worth, the guy I bought it from said he was moving, and had to be out quickly, and when I showed up he did have a crew loading stuff into a large moving truck. The story all went together, so I don't want to badmouth anyone without proof, especially since it's public record where and how I got the tractor. It's discouraging to feel taken advantage of, though, because I essentially took his word that I would have to reassemble the top end of the motor and then chug happily off into the sunset. Oops. Thanks again for the advice and tips. I think there is a lull in the rain here, so I'm going to plug away on the motor issues.
