Front-End Loader Loader bucket cylinder replacements

[Believer45]

Kubota L305DT with Bush Hog 2240QT loader

Both the bucket tilt cylinders on my loader started leaking badly. Bush Hog uses the wire style attachment for the cylinder heads. I was able to get the heads to turn but the wires have evidently broken off inside the groove in the head/cylinder bore as they stopped moving with the heads when you turn them. OEM replacements range from $670 to just shy of $1,000 each. OEM bore is 1.75 inches. I have found aftermarket replacements that will fit for $133 each (shipping included). They have similar stroke but the bore is 1.5 inches. Since this is on the bucket tilt and not the lift cylinders my question is will the smaller bore (about 25% smaller, if my logic is working that means more speed and less power) be an issue?

Any insight is greatly appreciated.

Thank you ------ Dave / Believer45

Pressure and flow is what determines the power of a cylinder...the size of the rod would be a strength issue...

BTW...1/4" is 1/7 of 1-3/4" which would be about 14.3% I think...

Good Luck...

At 2500 psi you’ve got about 4400 pounds push vs 6000. Also the loader curl does it’s main work with the retraction stroke so the rod size is also important. I don’t think you’d be happy with that kind of loss. The previous posters calculations for percentage loss are incorrect. When you’re dealing with the area of a circle double the diameter is 4x area.

Drill a blind hole directly into the gland through the slot in the barrel where the wire exits. Insert a piece of wire, cut off screw or something that fits into your blind hole and sticks up just high enough to clear the top of the groove in the barrel. Turn the gland, if you have a strong enough slug of metal cut the right length the wire will come out. Do not drill more than 2/3 of the way down to the cylinder rod.
If you do this correctly and it works (it usually does) the gland can be re used.

I apologize...I was only thinking of rod dia. and not the bore...!
