3PH wont raise

[DaveNay]

Arrrrggghhh.... /forums/images/graemlins/mad.gif

I just noticed that my 3PH isn't raising to it's full up position. I had noticed a few weeks ago that my rear blade didn't lift very high off the ground, but when I looked at it again, it was fine. I chalked it up to an observation error on my part. This weekend though, I can certainly say that it does not come up all the way. When I move the lever to it's full up position, the arms come up about 2/3 of the way and stop. I can lift them by hand all the way, but they just drop back down again. I checked my hydo oil level and it is fine, so the hydraulics shouldn't be getting starved. Any other suggestions? /forums/images/graemlins/confused.gif

Thanks,
Dave

If it were a Kubota B2710, I know where there's a simple adjustment, but I'm not familiar with that Deere. However, I'll bet if you look at what rods or linkages move when you raise it on up by hand, you'll see where the adjustment is. Or your Operator's Manual should show the adjustment (at least Kubota's do).

Does anyone have any ideas about this? /forums/images/graemlins/confused.gif /forums/images/graemlins/crazy.gif /forums/images/graemlins/frown.gif

Have you called your dealer to ask him? /forums/images/graemlins/confused.gif /forums/images/graemlins/smile.gif

Dave,
I have a service manual. I'll take a look tonight and see if anything like that is covered. I'll get back to you later.

From what I can tell, the manual says to try this (6) first.

Don't ignore that comment on those instructions that the "lift arms should have a small amount of play at full raise" because if it's still trying to raise more, you'll have a relief valve open all the time the lever is in the full raise position.

Bird, is there any way you might be able to tell me how to adjust the 3PH lift height on the B2710? I have a B2910 and I don't think mine is lifting high enough. My operator's manual has nothing in it (I cannot find it. There is a lot I cannot find. ) on how to do it. My manual covers the B2710,B2910 and the B7800.It was printed in 2003. Thank you very much in advance for any help. Also I wanted to ask how your wife is doing?

Richard, the manual for my B2710 (hmm, now I wonder if it was the Workshop Manual instead of the Operator's Manual) had instructions with pictures. First thing is to raise it all the way with no implement on it, then just try lifting the two arms higher by hand. I don't have the manuals anymore, so not sure I can remember all the numbers, but you should be able to easily lift those two lift arms about a half inch (the little bit of play mentioned in OkieG's attachment). If you have more play than that, then you may want to make the adjustment so it will raise higher. Now how am I going to describe this without a picture? /forums/images/graemlins/confused.gif Instead of a turnbuckle, as shown in OkieG's attachment, the B2710 had a threaded rod running through the little lever? that controls the oil flow to the 3-point cylinder inside the housing under the seat. You'll find that threaded rod with linkage connected to the top of the right lift arm. There is a jam nut on each side of lever it runs through (10mm nuts, if I remember right). You can loosen those nuts so you can adjust the distance that threaded rod will go through the other piece.

Not a very good description maybe, but I think when you raise the lift arms by hand while watching the linkage connected to the right one, you will probably see for yourself and understand how it works.

 

[DaveNay]

Thanks OkieG!!!! /forums/images/graemlins/grin.gif

That was exactly the problem. The jam nut had loosened on my assembly, and I could see bright threads where the turnbuckle has vibrated loose. In fact it had loosened so far that the entire assembly was only about 1/2 turn from coming completely apart.

I guess I am going to need to get me one of those service manuals if I am going to keep avoiding having my dealer do this type of work. Do you know if JD still has them available?

Thanks again!

Dave

Wow! Looks like you caught it just in time.
I suspect JD stopped printing X55 manuals when those model tractors went out of production in '97 or '98. I've posted a pic of the cover of mine if you are curious. The good news is that there are printing companies that make a living out of publishing out of print manuals. The JD dealer is the place to start. They will have a publishers name and number for you to call. I'm almost certain somebody still prints manuals for our "old" tractors. You should have no trouble getting one. Maybe even someone on this forum could provide the information for you?
I'm glad your 3ph is back on track.

OkieG,

Is the technical manual available for every tractor model like the 4110 for example? Are the JD dealers willing to provide those manuals to the "end user"?

Thanks!

[OkieG]

The parts dept. will gladly sell you one if they have it in stock...but they probably won't stock your tech manual. If JD still sells 'em, your dealer can order it and probably have it for you in short order. If your tech manual is no longer sold by Deere, hopefully your dealer will have information on a publishing company that does print it. I believe your dealer will be gald to help you find a manual.

OkieG

PS- I just looked at the Deere Web site. The operator's manuals for 4000 TEN series CUTs are still available, so with any luck the Tech Manuals will be available, too.
Deere probably offers two Tech Manuals for your tractor. One is dedicated to the engine only. The other is for everything else about your tractor. The Engine Component Tech Manual will help you tear down and reassemble every nut and bolt on the engine. I have that manual, but hope to never have to use it.
The most useful one for me is the Compact Utility Tractor Tech Manual. Yours will likely cover some engine items, like engine/fuel operational checkout and system diagnosis. It will also cover everything you'll every want to know about all your tractor's other systems. It will pay for itself the first time you use it.

Dave and Hyp3rnix,
Please let me know if you have trouble finding a manual. I'd be glad to talk to my dealer and see if he can find one for you.

Dave,
Here's one for sale on eBay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2597406712&category=53063

Thanks Bird. I will check it out in the morning. You explained it very well.

JDParts has the tech manual for the x55 series tractors, but it's $145. This seems a little high /forums/images/graemlins/crazy.gif /forums/images/graemlins/confused.gif I think I will keep an eye on the one on eBay just in case. How comprehensive is the manual? If it is worth the $145, I don't really have a problem, but I have no experience with the JD tech manuals. Also, I think I have heard that the service manual for the Yanmar engine is a different publication. How much of the engine is covered in the tech manual?

Hmmm......JDParts has the CD-ROM version for only $75, but it also says it is an obsolete item.

That's extremely high compared to what seems a reasonable cost of printing. I bought mine when I got my tractor in 1998. Then, I recall paying under $100, but not much under.

<font color="blue"> How comprehensive is the manual? If it is worth the $145, I don't really have a problem </font>

I am not a widely experienced Tech Manual person, but I believe this manual will walk you through about any project. I think it's the same manual the service guys use. I used my manual to help me rebuild a broken front axle spindle mechanism. There are many, many pictures illustrating every step. The sample I posted for your 3ph adjustment is a good example of how the book is put together. In my opinion, the manual is very comprehensive and written and illustrated so a somewhat mechanically inclined non-mechanic like me can work his way through. If you plan on keeping your tractor for a while you will probably get the chance to use it a few times.

<font color="blue"> the service manual for the Yanmar engine is a different publication. </font>

Yup.

<font color="blue"> How much of the engine is covered in the tech manual? </font>

The Contents page of the Engine/Fuel chapter is attached. The engine manual is detailed enough for overhaul/rebuild. The engine section of the Tractor Tech Manual covers more testing and adjustments rather than massive dismantling and rebuilding.

Ya know Dave,
Now that you're in a book shopping mode...if you run across a Parts Catalog for a reasonable price, you won't regret getting it. There's been many a time the poor parts guy looked long on his computer for a part I needed. And sometimes, I'm not sure the part he found was the right one. If you're armed with a part # you don't even have to go to the dealer. Just call him on the phone. If they have the part, great. If they have to order the part, you haven't wasted a trip, and it can probably be mailed to your house whether it's in stock or needs to be ordered. If you live close to your dealer maybe a trip or two is no big deal. My dealer is half an hour away. Sometimes I like to make the trip, other times it's nice to let my fingers do the walking, especially for small parts.
