Would anyone have a hydraulic schematic for a Cat 277 serial is JCNC012.. I can't make out the other 3 numbers. It is a straight 277 not A or B. The hydraulics all seem a little lacking in effort, as if you aren't moving a spool through it's complete range. I am thinking possibly low pilot pressure or maybe a hidden screen or filter somewhere. All functions work, just not giving full power out to the cylinders or travel. Thanks
Are you sure the Serial Number prefix is not CNC rather than JNC..? CNC is the S/N prefix for the earliest model of 277. If it is CNC then PM me with your email address. The same Hydraulic Schematic works for all 277 loaders S/N CNC1-Up so there is no need to know what the last digits of the S/N are.
