Eurocan MK6 EF Compound Gun Service

[John Jenner]

We just received an MK6 EF compound gun back for a service from a customer in Asia; I thought I would start a thread to show what is done.

In this first post we will cover the strip down of the gun and what we found, then I will post again when the repair is approved and the gun is rebuilt.

This unit was manufactured new in 2007 and this is the first time it has been sent back to us for a service. It was in pretty bad condition as you will see:

• The nozzle body, nozzle nut and nozzle body clamp are very distressed and in bad condition
  

• The integral bush in the gaiter clamp is very worn
  

• The gaiter box is very distressed
  

• There were no screws retaining the adapter plate which is also distressed with damage to the thread OD
• The needle is badly worn on the tip
• There was no nozzle present
• The front plate is very distressed, retaining screws are missing and seized
  
  

• Both solenoids are very discoloured and distressed with a taped repair to the wires
  

•  The armature washer is missing
• The bush in in the lower solenoid plate is very worn
  

• The backplate is very distressed
• The cable connector has visible damage to the thread
  

• The test fire button and boot are broken
  

• The gun has been completely dismantled
  

We have proposed that the gun is rebuilt with these new parts:

1x   10167SIG   Nozzle Body
1x   10160  Nozzle Nut
1x   10162SIG  Nozzle Body Clamp
1x   10175SIG  Gaiter Clamp

The assembly of this MK6 EF compound gun is being done in conjunction with the build and repair of two other units.

The first procedure is to fit the bushes in the upper and lower solenoid plates.

After being pressed home, each bush is reamed by hand to ensure the correct slide fit with the needle and anvil stud.



Now the upper solenoids are attached to the upper solenoid plates. It is really important that the correct specification screws are used. Incorrect screws can damage the brass thread in the solenoid casing, and pierce the plastic covering on the solenoid coil.



The anvil stud is then fitted and screwed into the armature with a drop of Loctite thread locker.





A special flat spanner is provided to hold on the internal flats of the armature whilst tightening the anvil stud.



The lower solenoids are attached to the lower solenoid plates together with the adapter plates using the special low head socket cap screws.




The armature washer sits on the bottom face of the armature.
