Getting a Yanmar repaired

[Fredster]

I'm pretty clueless when it comes to machinery, so this may be a dumb question.

While cutting my field tonight, the main belt in my engine case broke (model: FX24D). There's probably a name for that belt, but I don't know what it is. It connects the fan behind the radiator with a couple of other things. When the belt broke, the 'charge' light came on, so I figure if there's an alternator on the tractor, the belt was connected to that, too. Again, bear in mind that I don't even know enough about what's in there to be dangerous. I'm lucky I identified the broken thing as a belt.

My question is this: I bought the tractor from Fredricks, who is about 20 miles away. I don't have a trailer to get the tractor to them. I know they'll come pick it up if I want them to, but I figure it'll cost me an arm and a leg to have them do that. There's a CASE dealership about 1 mile from my house. Should they be able to replace the belt for me, or should I only take my Yanmar to Fredricks?

Thanks in advance.

That's called a "fan belt" and is a very simple matter to replace. If it was me, I'd take the broken belt in to just about any auto parts store, get one the same size and replace it. That will undoubtedly be much less expensive than getting a mechanic out to the tractor.

In any event, don't run the engine for any extended time without the belt. The fan won't provide any cooling air flow through the radiator, and if there's a water pump on your engine, coolant will not be circulated. The engine will overheat very quickly and then you could really have a problem.

To install the new belt, you'll need to loosen the bolt(s) holding the alternator so that it can be pivoted inward to allow room to place the belt around the pulley on the fan/waterpump, the big pulley at the bottom (crankshaft), and the one on the alternator.

Once it's around all the pulleys, and with the alternator bolts loose, pull outward on the alternator (probably need a short pry bar) putting tension on the belt - should be able to deflect the belt 1/2" or so with moderate finger pressure. Then tighten the alternator bolts, recheck the belt tension, and you're done.

The belt is an A39.

Fredster,

Where are you in N. Alabama? I'm in Rogersville, Maybe I can help you.

Send me a PM.

YOU the man, Eddie!

We all assume changing a belt is simple....but IF you've never done one before It might be a challenge. If I had never done one before I'd want to watch someone or get a little instruction.

Fredster, IF Eddie, or any other competent mechanic shows up, seize that moment and find out as much as you can concerning air filters, fuel filters checking the oil and other maintenance issues you Must perform. Somehow I just have a feeling that you don't know what you should have been shown...or the opportunity never presented itself before. Good luck,

Mark

Thanks for the suggestion, Tom --- you definitely make it sound easier than I thought it would be.


Thanks, Danny, for the part number; that'll make it easier to find what I need, I think. At the risk of sounding TOO dumb, is 'A39' a Yanmar number or is that a universal belt number?

For the record: I'm not stupid about everything. Computers, I know. Tractors, I don't.

Eddie, you have a PM coming.

You're welcome. Sometimes working the belt into position can be a little frustrating. The clearance between the fan and the radiator on my tractor is tight enough to make getting the belt around the fan a little more trouble than it should be, but, all in all, it's really not a difficult task.

Thanks, Danny, for the part number; that'll make it easier to find what I need, I think. At the risk of sounding TOO dumb, is 'A39' a Yanmar number or is that a universal belt number?

It's a universal V-Belt size designation. The "A" identifies the belt's cross sectional size and the "39" is the belt's length.

For the record: I'm not stupid about everything.

You proved that by asking the question.

I wish I knew computers

I sure hope it's not stupid if I don't know about something

I have been in a fight with my computer last couple of days, changing out hard drive without loosing data on old one. also adding DVD burner.

I think it's easier to learn about tractors than it is computers

Fred, you have PM coming back to ya.

Fredster,

I am from East Limestone and recently back from Iraq. If you get the belt and let me know a time, I can swing by there sometime. I have been busy catching up here this last week. I need to get my hands dirty on a tractor again.

 

[Eddie]

Brent,

Man it's good to hear that you're back.

Thank you for your Service.

 

[Fredster]

Well, it took me about an hour, and a second trip to the auto parts place, but I'm pleased to say that I got the fan belt changed out and everything appears to be working properly -- no overheating, no charge lamp, no more hard time engaging the PTO. I just finished cutting the field, and she handled it like a champ.

It took me a little more effort because I couldn't get the belt around the alternator, even when it was rotated up as far as it would go. Probably I just don't know the secret, but taking the bracket the alternator is connected to off let me move the alternator a touch closer, and it was a piece of cake then.

Thanks for all the help, guys, and thanks especially to Eddie and Brent for offering to come help in person.

I'd like to add my thanks as well Brent.


Fredster...Job well done.

 

[Eddie]

Way to go Fred,

Now if I could just get my Windows XP to work as well

 

[Fredster]

Eddie - if you want to PM me and tell me what your XP problem is, I can try to help you. I'm a software guy, and not so much an operating system techie, but I'll be glad to give it a shot.

I'm going to ressurect this older discussion. I found it helpful and may provide a solution for my issue. My charging light (battery) stays on until I get rpms up to above 1500rpm, then it will go out. I noticed that my fan belt is stretched out and has about an inch of play (twice what it should be). All the adjustment with the alternator is gone.

Fredster, you're saying you had the same charging light and a new / tighter belt solved it?

Last question, would the "A39" be the same belt used on my YMG2000D? I ask, because I can't size from the current belt.

A33 on the YMG2000D.

A lot of times the size of the belt is stamped into the outer side of the belt, or stamped on it with ink. Take a look at it when you get it off, in case somebody rerouted a belt for some strange reason. I had a friend who wanted his alternator to run a little faster at idle, so he changed out the pulley on the crankshaft to a larger on. The original belts no longer worked.

good idea, but I suspect I don't have the correct belt right now. The slack with the alternator adjustment is all the way out and the belt still has an inch of slack. I don't think the stretch that much. the previous owner probably put on too big of a belt.
