Back at it with the home made line boring machine to sort out loose steering pins on a JCB 416s
So after 11 years of use and several thousand hours of work the pins have worn the mounting holes in the chassis.
Tight space but a reasonable job to do. Line bore out the worn holes, machine up some new bushes and press into place. All without having to split the machine.
