I am in the process of re-plumbing my saddle on my 4020, but I think the lube lines were run incorrectly when I got the machine. This is how they were run:
Metering Valve
06E (small in size) Y Screw
06E (small in size) rear gib
20E (large in size) (near) Turcite
10E (medium in size) (far) Turcite
20E (large in size) front gib
06E (small in size) center way
Anyone know anything about this?
