What are these?

This is a shot of my CK35 (CT235) hydraulic block beneath the floorboard. What are those two protrusions above the row of four QC's?

Thanx

I suspect those are part of the joystick valve assembly that controls hydraulic flow to the loader. If you look at the back end of that thing I think you'll see the cables that come from the joystick. Specifically, these things are "caps" that contain the centering spring and detent (only for the lift valve) function for the two control valve spools. I must say that your setup looks much more accessible and compact than the arrangement on my 2006 DK45s.

That’s I believe where other rear remotes would go.

Richeyvs is correct. My CK30hst is the same. One is for the fel lift fuction and the other is for the curl. The ends of the spools are there with attached springs for centering the valves. When my control was hard to get into float, I removed them, cleaned, and re-greased. I also put a very thin film of silicone seal on the flat surface of the cup that mates with the control block to keep out any moisture. No hydraulic fluid is in the cups with it being kept in the valve block by sealing o-rings.

Thanks, all. This is a 2011 or 2012(last minute upgrade at purchase leant to some documented confusion) however it's worthy of mention the even newer hydraulics for the loader bring located above the floorboard by the forward mounted controller. I've colored zip ties on my but I always forget the order and am constantly forced to stick my head under there to determine which is which.

Good to know.
