Here you go Jim!
I have that exact same loader on my 3910.
I also have a Model 22 on my 5610-2
The cylinders are identical except for bore.
You would want the 2" bore cylinder for that loader.
The Farmhand part # is 22-1049 for the 2" bore cylinder, and is listed as non-current.
The 2.5" bore cylinders on the loader for the 5610-2 have a Farmhand part # of 22-1021.
If you need dimensions of cylinders, post back, and I'll do some measuring for you.
Edit: First 2 pictures are of the Model 30 (??) on my 3910. I can't verify that it's a model 30, as I've never found a name plate on it.
This is a Model 22 on my 5610-2. The dimensions and geometry are identical on both loadersb, but the 22 is build a bit heavier, and has the larger bore lift cylinders. the lift cylinder length, pin size, stroke, etc are identical on both loaders. The 22 with the 2.5" bore cylinders has a lift rating of 2800 lbs. I think that the 2" bore cylinders wil give a lift of 2000 lbs (+/-) which is probably plenty on the swept back front axle!
