Hello, I picked up a timber king 201 head with a loewen aftermarket wrist for 350 degrees rotation for my cat tk741, was hopping to speed up the rotation on the wrist, all other functions / grab arms and acumalters work fine. Thanks

Hello ,finely got back to this unit, it had a single hyd cly for head left to right. the update Loewen wrist is 2 hyd motors, so flow is the problem, the valve band is controlled by proportional valve iqan -mdm . I have done some digging on their site, found a manual seems like it can be adjusted . Has anyone done this or know a better way to speed the tillt up. thanks

There's not really a good way to do it without spending huge money. That's a downfall with some of that old computer controlled gear, it's pretty much outdated at just 10 years old.
