Do you guys happen to know if there is anyway to lock the 3rd or 4th valve on? We are going to be running a truc brush broom and it would be super handy to not have to hold the lever while the broom spins. I know the lift and curl use magnets and prox sensors to hold in, but im unsure about 3rd valves. Thanks in advance!!
The servo blocks are the same. You would just need to get the magnet and plate for a let's say return to dig function or similar. I would strongly suggest wiring into an e-stop on the A pillar. The magnets have a good hold when adjusted properly, easier to hit a big red button than to fight a mag in an emergency. Look to an E or F series catalog for more options
Thanks for the reply. Would the magnets go on the pilot controls, or on the actual valve block?
Pilot
There was a kit for constant on 3rd function in the F catalog. Also has the option for the E stop which could be retro fitted to the D . I used this same option to power a log processor on an L70F
This attachment needed constant flow and had its own control lever
I contacted volvo today. They claim these magnets are unavailable. Do you know of any aftermarket or used sources for these?
I do not know of an aftermarket source the only suggestion I would have is to try perhaps another dealer
The option for 3rd function is 80098. I have no idea if all of the parts are still available.
Ben, I think he has 3rd function, he just needs to lock it "on." Like boom float , or raise to kick-out. His dealer is telling him that the magnets are no longer available. They used the same servo manifold up to and through the G series, didn't they?
Our L70F has no lock on the 3rd valve. The angle is on a toggle. Sounds cheap, but I just use a rubber bungie cord
You know, in all honesty, simple is better.
This machine has 3rd and 4th functions from the factory. We will be running a truc brush attachment which needs constant flow for sweeping snow from the top of semi trailers. I figured i would just buy the magnets from volvo but my dealer says they are NLA. After looking at the pilot valve section, i thought about buying a 24 volt electromagnet and making my own bracket to hold the pilot levers engaged.
I'm sorry I should have been more clear. The option for 3rd function detent is 80098. This can be installed as an aftermarket option but as I stated I don't know if parts are still available. There is also an option for varible fixed flow I believe, as this option will be fixed max flow. But you should be able to adjust the limiter screws on the 3rd function spool to limit flow if it is too much.
