First build ,cat D11

[9W Monighan]

You need to add spherical rod ends on the cylinder rods.
I helped a mechanic install a blade on a D11N back a few years ago. We a had a heck of a time getting the push arms aligned because it was a low hour machine at the time. The mechanic got his torch out and started cutting the spherical bearing just as the big boss came around and gave him h e ll. The next morning I was passing by and the Cat Dealer mechanic was there installing a new push arm end.
