Hi All TBN-ers!

I recently put on a hydraulic side link to my Kioti CK2610. It appears that it doesn't fully retract based on the 'silver' reveal. My hydraulic top link does not have this problem. My question to the group: Is this normal? The pic you are looking at is "fully retracted". Can anyone give me guidance?

Thanks! Cylinder Won't Retract Fully.jpg

It could just be paint. Usually there is some exposed bright cylinder rod showing. Real question has to be, was it ever any different? Then, I might expect some air.

Measure total rod travel and compare that value to the length of the barrel itself. Should be within about 3 to 3-1/2 inches to allow for the width of the piston and the part of the gland and end cap within the barrel.

A should be, approximation isn't going to tell him anything. Not when he is wondering is an inch should be there or not.

Contact the vendor and get the stroke spec of the cylinder. Or find your invoice and do an internet search of the part number, the stroke spec might come up in the results.

Measure the stroke, I would guess that it is 4". It is very common to have part of the remaining extended rod not painted. I would bet that your side link and top link were not built in the same facility and may explain the exposed part of the rod not being painted.

Can't say I recall seeing a lot of cylinders that don't have some shiny rod showing. Nor any, actually.

Is that normal? I don't know what's normal or not for your cylinder, but none of mine do that that I've noticed....not that I notice that much.

I had one cylinder recently that was not completely retracting. It turns out that the end nut that holds the piston in place was never tightened right and was coming loose. The only way I can see to get real information is to take the hoses off the cylinder and compress it until you feel a hard stop. You ought to be able to do that by hand or using the lift arm as a lever. You might even be able to tell if the nut is coming loose.

Thanks all! I'll measure the stroke today and ask the vendor. My mild OCD will drive me crazy until I figure this out.

Don't you just love OCD.....:)

Its possible you have a wee bit of air left in the cylinder that hasnt been bled completely. That would be my first guess on a new cylinder install. Do you have any bounce on the cylinder stroke?

I am interested in doing a hydraulic side link on my CK2610. Would you share where you got your cylinder from?

Most likely just from how it was taped off before paint.
How far does it extend, 4"?

Not the OP, but if you want a side link built to provide an equal amount of tilt to BOTH sides, you might want to try Fit Rite Hydraulics. Most side links available for these models do not provide an equal amount of tilt to both sides and still maintain the left side (OEM) dimensions.

Disconnect it from the 3 point hitch (both side) and cycle the piston back and forth with the "bottom" facing up...

It's a 5 year old thread. Hopefully the OP has it figured out by now. 🙂
