Greenmech Quadchip 160

I still use the quadchip and have put some maintanance in it. Because the hydromotor of the stuck roller was damaged on the seals and leaked. I replaced them with Danfoss motors. Those are a bit bigger build but fit with some alternation of the springtensioner mount on the top roller. I also fitted a unpresurized returnline from the motors to the tank. Also i replaced the greasenipple from the rear bearing on the flywheel with a greaseline from the outside. The original nipple didnt torque in the right spot to put a greasegun on and the nipple would untight itself and fall out. Last but least i turned the anvils, was not that difficult but had to make a slide hammer to pull the vertical anvil. I cut some steel away within the turntable to make some more access. The horizontal anvil was easy to tap upwards into the feedbox. Took me an hour, including making that slide hammer. Machine is from 2017 and has 400hrs. I have a tarp made for it so rain doesnt get in the machine while stored. 

 

Danfoss hydromotors fitted

 

External greasline to rear bearing

 

Cut flange for space to vertical anvil

 

Slidehammer m12 threaded rod with 10mm round bar welded to fit the hole in anvil.

 

Wear vertical anvil is most on topside (400hrs)

 

Horizontal anvil wear is most on right corner (400 hrs)

 

I also mounted an fiat idea 1.3 Mjet intercooler with some silicon hoses. This stopped the chipper from overheating in summer.

 

Two ledlights in the feedchute very helpfull at dark (rainy)days and nightwork to see the feedrollers and how branches feed.

If you remove the moving feed roller carriage you can cut about 10mm out of the "chassis" by where the fixed roller is allowing the moving feed roller to close further. We have got them down to 5-10mm gap.

 

Measure five times cut once... Happy to take a photo if it helps.

Photo would be great if possible 👍🏻
