A 5,466-page Caterpillar repair manual set for the 314D LCR and 314D CR hydraulic excavator, serial prefix SSZ00001-UP, powered by the Cat C4.2 engine. It is a Caterpillar SIS export of several factory books interleaved, each page carrying its own media number in the header. The two fold-out schematics are the reason to own it.
On page 5270 sits the interactive 314D CR hydraulic system schematic, part 270-6045, a full colour circuit where almost every component carries its own Caterpillar part number: main pump 311-7404, main control valve 270-5960, travel motors 277-6697, swing motor 274-2636, swivel 162-4696, joysticks 297-0533 and 297-0532, pilot accumulator 164-6981, case drain filter 288-8194, return oil filter 188-4145, hydraulic tank 282-7220. A colour key separates the circuits, from right and left main pump output and pilot supply through travel speed control, powershift and attachment control to boom, bucket, stick and swing brake control.
On page 5286 is KENR7795, the 48 by 35 inch full colour electrical sheet, part 336-6129, with wire groups colour-coded by function: ground, key-off and key-on circuits, charging, starting, monitor, machine control, security, heater and air conditioner, wiper and washer, and the RS-232 and CAN data links. Measured page by page, the set runs 1,962 pages of machine hydraulic books, 1,443 of machine electronic control, 1,236 of generic C4.2/C6.4 engine books, 417 of air conditioning and 379 of the D Monitor system.
