Hydraulic Rockshaft slipping, loose (?)

[suffering_jukebox]

l3450 DT-GS. Parts Diagram.

Was swapping implements the other day- noticed this gap allowing me to see straight through to the rockshaft.

There's an external circular clip on the left side that looks a little bent- it's one thing to twerk some of the lift arm components, but I can't hazard a guess as to what would have disfigured that clip the way it is. Don't have a good pic of that side at the moment unfortunately.

I thought the right side was tight, but I think it was just underload. Will take a closer look tomorrow. I do ask a lot of this machine this time of year- demanding a fairly muscular performance over the past few weeks chiseling and disking about 3 acres- in addition to it's typical workload of brush hogging, etc.

Never have had to deal with this area of the hydraulic system- advice, words of caution, information, general assessment of repair exigence all appreciated. Thanks everyone.

At a minimum I suggest replacing both external snap rings, ensure the groves are free of burs, dings, etc. Be reminded that snap rings need to be properly orientated. It appears that your top link could use a Cat 1-2 bushing.

Expanding on the above comment regarding snap ring orientation, take this into consideration. If you examine a snap ring closely, you will see one edge is slightly rounded and the other is sharp, or not so rounded.

The snap ring should be oriented in its groove such that the axial thrust is forcing the "sharp" side of the ring into the side of the groove.

In your case, the "sharp" edge of the snap ring should face the fender(s).

A twerking tractor - what is this country coming to?

Oh, we've sunk much lower than a twerking tractor, of that you can be assured. Look at the goons teaching (indoctrinating) in the public schools.

Well, how do you dislodge debris that get wadded up in the York rake?

Lol kidding- weird word choice on my part haha

Damn - after 37 years of teaching = not sure I even KNOW what a twerk is, much less teach it.

Remember - just cause the news reports something, does not make it 100% true.

The news often tells the truth, but rarely the WHOLE truth and much more rare "nothing but the truth"

For example - all cops beat up on people............ .000001% True , but all we hear is cops are terrible people.

I ASSURE you - teachers today are working harder and harder to teach between those guidelines that SOME idiots think are the "right choices" in the subject matter.

Right on

thank you and to Motion for the specifics- I was able to press the link arms back together against the housing, so here’s to hoping it only needs those external components replaced

It is still kind of a mystery to me as to how that snap ring on the left got so dinged up. My best guess is something pressing against it when I raised the three-point but I can’t imagine what that would be. Oh well, hopefully I never need to know because it never happens again

The snap rings keep it all together but the rock shaft is VERY robust - it will lift a house without breaking a sweat, and never sees very much side force anyway.

FWIW the rest of the chasis will fail first if top link force is too high - 2014 pics of an L4610 with a winch and long logs drawn up tight when the front wheels dropped into a dip. Rear housing broke but rock shaft & cylinder not even scratched!

Usually there’s no horizontal force on the lift arm to push it off the splined shaft, so it takes little to nothing to hold it on and tge snap ring is more than sufficient.

Once in a blue moon, I’ve seen one pushed off the rock shaft and there’s a mangled snap ring testifying to some significant force involved. I’d push it back on, replace the snap ring and roll on. If it happens again maybe investigate / consider what’s happening to get it in a bind to create the rather unusual force vector and severity of force to push it off.

If you get curious, look it up. If you have a personal computer and a work computer, look it up on your personal computer. Do NOT look it up on your work computer.

yeah, i do KNOW what the "dance" is ....... but rather NOT watch it!
