Re: 3CX JCB 1997 Maint. questions
Thanks Norm, it certainly worked well.
using the drop-out gave high strength without needing an exotic steel.
This spanner is 96mm to suit the boom ram - happy to provide the CAD file if anyone wants one from your local laser cutter.

Not a problem - you don't need to.
You just need to find a local fab house with a CNC profile cutter (laser, plasma or even water jet), give them the drawing (email or USB stick) and they'll be able to cut the tool.

There is a fab shop close by, they laser cut and bent the the window frames for me, done an excellent job. So how would I go about getting the info to make one If needed? I must have been lucky with my boom ram as the cap nut was barely hand tight, getting the pin out of the king post was a different matter. (as posted on here).

Re: 3CX JCB 1997 Maint. questions
Hi all.
I was giving the 84 3CX some TLC the other day when I noticed that 3 or 4 glass panels had JCB Newcastle upon Tyne imprinted in them. Anyone Know what that's about?

Sorry Norm, I thought I'd replied to you.
Just send me a PM and I'll email you the CAD file.
(offer open to anyone else on here too)

Re: 3CX JCB 1997 Maint. questions
Removing a broken dowel.
Another piston seal has has failed on a shovel tilt ram resulting in the shovel emptying it's self if it isn't pulled back regularly.
Pulling the ram down was straight forward, but it looks like the last person in there wasn't so skilled.
The dowel on one piston initially seemed to be absent, but on closer inspection turned out to be broken at about the rod/piston interface.
Given how hard the dowels are, the only way I can think of to remove it is EDM (spark erosion).
Any other techniques come to mind?
