KL 1450 loader

[DK35vince]

In previuos posts I mentioned I was dissapointed with the tilt power for my bucket.
I have been doing a few changes to hopefully help.
I made longer bracket where the cylinders attach and moved the pins on my quick attach up 3".
I still need to dissasemble and paint the new pieces.

I had to trim back the quick attach a bit for the pins.

 

[DK35vince]

I also bumped the loader pressure up to 2400 PSI (I'm not recommending this, but I'm doing it !!)
I still need to test the tilt cylinder seals for any leak by.

Also added a set of lights to the ROPS.

Here is a picture of what the original bucket linkage looked like.

I now have all the bucket linkage and quick attach repainted and reassembled. No pictures yet.
I still need to add bucket stops (the originals are no longer in the right place)
Almost done and should have more roll back power.

I hope this works out better for you Vince - I'm impressed that you can make something like this. I have zero ability in that regards - Good luck with the mods - I'll be interested in your "final report".

Take Care,

I'm enjoying this project a lot Vince. I too wish I had the talents to do these mods. Keep up the good work, hope it works better. John

Looks good Vince. Let us know how it works.

I have a question about testing the tilt cylinder seals.
I rolled the bucket back against the stops.
This pushes the piston to the top of the cylinder, I then removed the hydraulic hoses at the top of the cylinder, started the tractor and held pressure rolling the bucket against the stops.
If the seals were leaking by oil should try coming out the top holes. That is my theory anyway. Is this correct ?
I saw no oil trying to leak past the seals.

 

[JerryG]

You did it right . Your seals should be ok.

 

[DK35vince]

Thanks Jerry.

Actually I was kind of hoping one of the cylinders was leaking by. Repairing that would help the power in addition to the other changes I made.
Oh well, hopefully the changes I made will be enough.
If not I will try something differant.
The ground here is frozen solid so its hard to put it to the test.

Great idea and great work I would be real curios as to how this works out. does it seem to help with the angle also.?

[DK35vince]

My roll back angle on the bucket is the same as before. I didn't gain or loose anything there.
I did loose some dump angle,I didn't put enough curve in the linkage I made and they hit the bucket near the lower bucket pin before I run out of cylinder.
I'm going to use them as is for a while to see if I gained enough roll back power.
If the power suits me I will just make new linkage with more curve on the lower half to clear the bucket pin so I get full throw from the cylinders.
Problem is every thing here is froze solid and it may be awhile before I can see what I gained.

vince, I think if there were a blow-by type leak your method should have found it.

Something else you may want to check. The hydralic pressure at the cylinder. I think it should be about 2000psi. It should be availible in the machines specs. You could have a leak in the control valve limiting its pressure.

 

[DK35vince]

Thanks Charlie,
The loaders owners manual calls for 2300PSI.
I recently turned the pressure up to 2400 PSI.
When I ran the hydraulic pressure test I plugged into one of the loader quick couplers coming out of the loader valve.
When running the test I was plugged in to the loader lift coupler.
You are correct though, just to be sure the loader valve is working properly I should also check the pressure from the loader roll back coupler .

 

[DK35vince]

Charlie,
I did as you suggested and tested the presure at the bottom of the cylinder, just to make sure the valve was OK and no blockages to the cylinder.
The pressure is good.
The seals are good.
Everything looks good, so the stock bucket pins being to close together (5") seems to be the only problem I can find.

Mr. DK
If you fill the bucket up with somethig heavy, Curl it all the way,,,,, will the bucket (tilt cylinders) bleed down? The cylinders should hold for days wheather the engine is running or not.
If the cylinders bleed down then give me an e-mail and I can tell you the fix. you may be barking up the wrong tree.
I,ve had that complant here a time or two.
