Anyone have any info on the aftermarket pattern control valves, we are starting a job that has half and half operators. Thanks in advance. Russ
Have used some and have no complaints so far, just make sure all operators are well versed in location and operation. We have used these before: http://www.holmburyusa.com/ftp/Products09/PattChanger.pdf Also have had to help get a customer straightened out after he tried to install one recently. Make sure the hoses are marked properly before you start moving them, saves a lot of time. Here is another little article on this valve: http://hansonhydraulics.com/wordpress/archives/pattern-changer-valve-holmbury-inc.html
Perfect, thanks a bunch.
Do you want a manual valve like dblaneyfan showed or an electic valve with a switch in the cab?
Good morning all!!! I learned on a JD backhoe pattern and now have a mini with a conventional pattern.. It takes some getting used to. Love the minis with the changeover valve under the floor. First thing I go for when renting a machine. Now that's out of the way, can anybody explain why there are 2 setups. Just imagine if auto makers never got together on the location of the brake, clutch and throttle.. Smashup derby big time!!! Later Ablebob.
Welcome to the Forums ablebob!:drinkup This pattern choice Cat or Deere/backhoe or excavator has been discussed numerous times on HEF. Well actually it's been beat to death.:cool2 Take a look around the Forums and do a search, there will be all sorts of information. However for this thread, let's keep it the "nuts and bolts" of adding a pattern changer. This information can be helpful for a lot of folks out there and doesn't need to be turned into a debate once again of which pattern is better.
Thanks for the info dblaneyfan. How much does that valve cost, in round about numbers?
The fellow that I had to help out said he got his for around $500 delivered from a Deere dealer (the Holmbury is also what our local Deere dealer sells, it's just an unbranded model.) But we have found them from $300-400 shipped. Like the Holmbury manual valve, very simple, nothing extra electrical to throw into the mix.
I did too ........ but as CM posted lets keep it clean !!! ........ the 2 styles came about when excavators had cabs mounted on both left and right hand sides of the boom ... to keep it simple .... "Hand closest to the boom controled that function" .... cheers
I was not aware of that, thanks for enlightening me!
I have four new aftermarket pattern changer valves sitting on the floor of my shop. For $200 you can have one. PM me if your interested.
this is a little bit of topic. had to post it here because i cant make a new thread, and it is kinda relevant to this thread anyway. I have a 20t with a foot pedal for the tilt bucket. I would like to get the tilt pedal elimanated and control the tilt buck with a toggle on my right joystick. Question is, is it possible, if so how and what is involved, rough cost, and how long will it take to do. Is the hand control tilt bucket better than the pedal. like is it more precise, easier to control.
Anything is possible ! .....first off, does your machine already have a thumb ? ........ if so you can control the tilt with it by adding a couple of mechanical 3-way diverter valves off of the hyd lines that feed the thumb ...if not then you would have to add an elec over hyd valve controler .... don't know the costs but i'd expect that it's not cheap ............ I'd look at another machine same as yours and copy what's there ..... good luck
no thumb on the machine.
Add a 3 position solenoid valve under the cab and move the pilot lines from the foot valve to the subplate on the valve. Run two wires from the solenoid valve to the right joystick. Run another ground wire from both terminals to the frame. Get yourself a joystick from Sure-grip . Run a hot lead to the joystick from your cigar lighter, tie in the two lines from the solenoid to the corresponding wires on the switchs and your done. Should take 1 man less than a day and total cost is around $500US.
Good info. I've wanted to do this for my ex120 from day one. Having the thumb control next to the travel pedals just seems wrong. my .02.
You will also need some way of slowing down the pilot oil activation by orifice or a reducing valve. Otherwise the start and stop of the thumb will hammer hard. (stop/start too fast)
