Too Much Pressure To Connect Hydraulics? Need Help

jinman · May 7, 2005

( Jim I know you wrote the book on loaders but we have always treated our 17LA loader a bit different and it has worked well for us. )

Mike, I didn't write the book, but I did take the pictures. /forums/images/graemlins/wink.gif

There's absolutely no reason your system won't work just fine. It makes your cylinders extend all the way out, but it accomplishes the same thing as curling the bucket and lifting the arms. Often, when I reattach the loader, I end up extending the arms to get everything into position.

My main reason for posting the picture was to show why the bucket could not be curled all the way down and sat on its face like Murph's picture shows being done with a 7308 loader. With our kickstand, I don't think that's possible.

That may not have come out the way I meant it. Should have said your article on the 16LA loader is a classic, it was well written and very informative.

Only meant to say that there is more than one way to skin a cat. I currently know of 2 ways yours and mine and suspect there's a member or two yet doing it a completely different way than us that hasn't even admitted it as of yet....

The next time I pull mine I am going to try your method Jim just because I have never done so before and doing things a little differently from time to time can't be bad.

Jim just as an update I did try your way on the 17LA loader today. When we curled the bucket fully up the loader would not raise enough to clear the loader mounts.

Would think the differences might be due to the fact that I have a QA but I believe that you now have one on your loader as well so that can't be what makes the difference in disconnecting.

I wish another 17LA owner might jump in here and tell us what procedure they use to dump their loader.

Mike,

I got an idea, why don't you buy me a TC40 and a 17LA loader and I will test it out for you?? /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif This way it would be good for me and you. I would get something free and you would have another opinion /forums/images/graemlins/grin.gif But something tells me are not that interested /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif

I can wait!! /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif Just make sure you get the block heater option for me. If it is not in your budget I can pay the difference. /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif

Mike,

I have a TC40D with a 17LA loader and do my install/detach the way you mentioned. Have managed to do it in ways similiar to Jim's technique but have also managed to bend the pins in the kickstand as a result of trying to convince the loader to disengage.

Dave, I'm starting to wonder if the different length of the 17LA makes a big difference. I normally put a wooden or concrete block under my stand on my 16LA and that's just enough to get the arms to lift. One time I did have to walk around front and stand on the bucket lip to get the arms to pop out. /forums/images/graemlins/smile.gif

BTW: The roll-up bucket technique is what is in the 16LA/17LA manual. I agree that if you extend the arms after pulling the pins, you make the job much, much easier. I just don't normally have to extend them anymore than 1/3 rather than all the way like PineRidge does.

Dave we have tried Jim's way but it doesn't seem to work for us. Haven't put anything under the jack stand though as in Jim's picture to afford extra height.

I have always assumed that the extra length of the 17LA along with the extra length of the quick attach plate made the difference in the way it gets connected.

The day the dealer delivered our rig this was how he showed us how to make the connection and we have never experienced any problems with the routine.

I figured there were more than a few others out there that might be doing it the very same way too........

Guys,

I wish I had read this thread the other day because I thought I was losing it!

I purchased my TC35DA at the and of Decamber and hadn't removed the 17LA loader until I picked up the mower deck and decided that mowing with the loader on the tractor was a bit much /forums/images/graemlins/wink.gif. Removing the loader as the dealer suggested (equalizing the pressure in the lines with the engine off) was a breeze.

About ten days later when I needed the loader again, I was EXTREMELY frustrated that I could not re-connect the hydraulic lines! I had no idea that parking the loader where I did (compacted sand) would allow enough movement to cause pressure build-up.

After using all my strength to push the connector ends against the loader mounts and wooden boards to no avail, I was about to losen the fittings themselves to relieve the built up pressure. Before I did that, I called my cousin who's been around tractors for twenty years or so to see if he had a trick up his sleeve. He told me to tap the end of the fitting with a hammer.

I know that banging on the end of the fitting could cause some damage, but I gave it a try and by golly, three or four (fairly firm) raps with a rag wrapped around the end of the line solved my problem. I checked the fittings after the "treatment" and saw no mushrooming or damage to the nipple on the end.

Quick and painless (a little messy) and ten minutes later I was moving some dirt!

I love my tractor! /forums/images/graemlins/grin.gif
