Front End Loader Question

I'm probably going to have a hard time explaining this, so please excuse me if I ramble around some.

I've had a CTC loader on my X739 for a couple years now, and it pretty much does what I need it to do. I've moved several tons of dirt and gravel with no issues, but today I noticed something that I had missed in the past.

I was moving some dirt around, for a neighbor, and as I was piling it up, I had the bucket up about eye level as I dumped it. As the cylinders extended, to dump the bucket, they actually hit the top of the arms. As the shafts continued to extend, they actually bent before they reached full extension. Guess I never noticed this before, because it was not right in front of me, but I can't imagine this is a good thing.

I'm guessing there are 2 ways to fix this problem. I could raise the point where the shaft attaches to the bucket about 2 inches. I'd have to check, but I think this might be enough to fix the problem. The other option would be to get a pair of cylinders that were a couple inches shorter at full extension. The bucket wouldn't dump quite as far, but I don't think this would be a problem.

Are those pretty much my options, or is there something else that might work. Actually, if I was working on a wish list, I wish the bucket would pull back a few inches more.

Thanks in advance for the help.

Re: Front End Loader Question

Going to be a lot less expensive to change the location where the shaft attaches....new cylinders will cost a small fortune...you say that they bent...do they straighten back out?
Depending on your set up you may be able to cut off the top part where the cylinders mount and move them back and do some fabrication and reweld them...this would also tilt the bucket back further....good luck

Re: Front End Loader Question

Maybe you could heat and ding in the high spots so the rod has clearance...

Re: Front End Loader Question

When I needed to roll the bucket further back to carry wet cement for a project, I drilled new cylinder pin holes on the bucket mount lower than the originals. Once the pour was done, I put things back to square one and never checked for the effect at max height.

What you gain on one end of the curl, you'll lose on the other. I suggest that you make a mockup of the bucket mount and back out of scraps of plywood and try various options. It only needs to be wide enough for one arm and cylinder. Tie the other cylinder out of the way for safety, because it will still go in and out as you try for the best curl fit at the top and bottom of the arm lift.

If you can't find the sweet spot on the bucket mount, then start looking at a change for the cylinder mount on the arm.

Change the cylinders only as a desperation move of last resort. Someone messed up in design or manufacturing to cause the problem, and it should be correctable unless it is the wrong cylinder.

As mentioned, a couple of pics from the side with the cylinders at both ends of the stroke would help.

Re: Front End Loader Question

I purchased a lightly-used CTC loader about 5 years ago and have worked it pretty hard since. Itís a fantastic piece of equipment.

That said, Iíve made a few changes to it over the years. One of those was to weld small stop blocks to the bucket, at the bottom of both mounting brackets. I had noticed the same cylinder-to-arm contact you mentioned. With the stops in place, I can instantly feel when the bucket is curled to full cylinder extension.

Re: Front End Loader Question

Thank you for the replies.

Mark, maybe bend is too strong a word. Flex might work better. You can see a definite curve as the cylinder hits the top of the arm, and the shaft keeps extending.

rayjay, I thought about that right after I cleaned everything up, and put it away. If it doesnít rain today, Iíll mount the loader and get some pictures.

Kbeitz, that would work, but Iíd like to save it as a last resort.

Tudor, lowering the shaft mounting holes on the bucket is not an option. That would make my problem worse. I canít do anything with the piviot points at the bottom of the bucket because thereís not enough material there. Iíd have to cut the mounting off the bucket, move it, and reweld or replace it. Would raising the rear mounting points accomplish the same thing? I will try to get pictures today.

AOW162435, I had not thought about that. That might be the easiest thing to do. It would keep the cylinders from fully extending, but it would fix the problem.

Re: Front End Loader Question

Got some pictures, but given the tools that I have, my abilities, and the possibilities of messing something up, I've about decided that AOW162435's idea of welding in a stop might be the way for me to go.

Re: Front End Loader Question

Iíll post a pic or two later. I sized the stops such that the rods get to within 1/4Ē of the loader arms. Works perfect.

Re: Front End Loader Question

Dave,
Here you go. Let me know if you need any measurements. I shaped the pieces of 1/2Ē cold-rolled steel and kept test fitting them before welding.

Re: Front End Loader Question

Got it. The pictures were what I needed. I was working way too hard.
If I have a picture, or instructions, I can do things. I guess I lack the imagination to come up with the idea.

You do NOT want to be banging into those hard stops.
