Haco Q5 Service and Q3 Teardown for Spare Parts to Make Room for LVD Punch
A punch shop floor only works when every machine has a clear purpose. In this project, the Haco Q5 needed leak repairs, control updates, and turret service, while the older Haco Q3 had reached the point where it made more sense to strip it for spare parts than keep it. AVM Technologies stripped the Haco punch machine for spare parts with pleasure!
The goal was simple: get the Q5 back into cleaner, more reliable condition and clear space for an incoming LVD punch.
Rebuilding the Q5 hydraulic system
The main Q5 service work started with the hydraulic leaks. The hydraulic manifold block for the fingers was rebuilt to stop oil loss and restore dependable function. This was not a single-fitting repair. The work covered the connected systems around the punch head and hydraulic unit.
Hydraulic hoses around the head and back to the power unit were rebuilt. The hydraulic valves received new O-rings to stop leaks around valve bodies and fittings. The punch head also received new O-rings and C-cup seals to correct oil leaks at the source.
Several fittings on the front head were tightened, and all transparent hoses were replaced. These clear hoses can become brittle, stained, or loose over time, especially on older machines that have seen daily production use.
The focus was not cosmetic. It was about stopping oil loss, reducing cleanup, and protecting the machine from avoidable wear.
Repairing air leaks and updating controls
The pneumatic side also needed attention. Pneumatic couplings, fittings, and hoses were replaced to correct air leaks. Air leaks can be easy to ignore at first, but they waste shop air and can create inconsistent machine behavior.
The control panel also received practical updates. The start pump and reset buttons were replaced, and new cycle start, stop, and reset buttons were added to the control. These changes made the operator interface more complete and easier to work with during setup and cycling.
All wiring of the finger manifold block was redone as part of the service. On older production equipment, wiring condition matters as much as hoses and seals. The wiring had become hard and brittle from being covered in oil for too long.
Restoring the tool turret stations
The Q5 turret also needed mechanical work. All tool turret stations were repaired, including new dowel pins, tool holder pins, and retaining rings. These parts play a direct role in station alignment, tool holding, and repeatable punching performance.
The bottom turret table received new bumpers as well. Worn or missing bumpers can create noise, vibration, and poor contact points during machine movement.
Stripping the Q3 down for useful parts
While the Q5 was being serviced, the old Q3 was torn down to the frame. The purpose was clear: save valuable spare parts and remove the rest to make room for the incoming LVD punch.
The teardown included removing:
Hoses, wires, tubing, and sensors
Wires from the electrical cabinet and control
Hydraulic parts and accumulators
Pneumatic parts
Covers, plates, brackets, hoses, wires, and tubing for recycling
Several major assemblies were kept for future support. The top and bottom head were saved as spare parts. The electrical cabinet and control were also kept, along with the hydraulic unit.
This kind of teardown keeps useful machine components available without storing an entire out-of-service punch press.
Making space without wasting value
The Q5 service and Q3 teardown supported the same shop goal. One machine was repaired for continued use, while the older machine was reduced to the parts that still held value.
That approach keeps the floor organized, lowers future spare part risk, and prepares the space for the LVD punch without throwing away components that may help keep another machine running. For older punching equipment, careful service and selective teardown can be the difference between clutter and a useful parts inventory.
