Ordering a take-up roller, recoil spring or swing motor part for an X3-generation machine starts with the correct part number, and this 734-page Link-Belt 350X3-EX parts catalog PDF (OEM ID 2256) lists them for the 350X3-EX hydraulic excavator. Exploded views break each assembly into numbered components, running from the Lowers group and turn table bearing through the Isuzu 6HK1 engine, pilot and auxiliary hydraulic lines, the operator's cab and boom and arm attachments. Electric Parts covers the wiring harness, battery and air conditioner, while Inner Parts opens up the hydraulic pump, traction motor, swing motor and control valve. Width matters on track shoes. Order 3-bar grousers by size: 700 mm, 800 mm or 850 mm. Your job may be pricing upper, lower and take-up rollers, or confirming the breaker plug group before plumbing in a breaker. Bookmarks drop you straight into Lowers or Electric Parts, and the text layer finds any part name across the 734 pages.

Link-Belt 350X3-EX, 350 X3 Common Problems This Manual Covers
Link-Belt 350 X3 can't find V-ring, O-ring and packing ring part numbers for the center joint
Open the center joint exploded view on page 32, then pull part numbers from the matching list on page 33 by item number. That list carries the seal ring, V-ring, O-ring and packing rings, and the packing ring is called out at a quantity of seven. Check the serial column against your machine before ordering.
Manual Section: Lowers p. 32Need correct high strength bolt and washer part numbers for the double track guard
Check the double track guard drawing on page 30, then the parts list on page 31. Order the track guards with the high strength bolts and high strength washers listed there, sixteen of each per assembly. Give your distributor the model, serial and manufacturer's numbers plus part number and quantity, as page 9 directs.
Manual Section: Lowers p. 31Can't find hydraulic pump inner part numbers from the main pump parts page
Start at the hydraulic pump parts listing on page 186, which also covers the PTO pump. Look for an asterisk in the breakdown column; page 11 explains that it flags a separate inner parts page. Then turn to the Inner Parts section starting on page 476 for the pump component breakdown and part numbers.
Manual Section: Control & Lines - Hydraulic Pumps and Floor Controls p. 186Pilot control line parts differ between HBCV and selector valve machines, unsure which page fits
Check the control and lines index on page 14. It splits the pilot control line into an HBCV version and a version with selector valve, and splits control valve mounting into standard and with 2nd option. Identify which setup is on your machine, then order lines and fittings only from the matching parts page.
Manual Section: Control & Lines (Continued) p. 14Attachment line part numbers differ by arm length, unsure which list matches my arm
Measure your arm and match it to the Attachments listings starting on page 384: short 2.63 m (8 ft 8 in), standard 3.25 m (10 ft 8 in) or long 4.04 m (13 ft 3 in). Each arm length has its own aux hydraulic lines page, and the 6.45 m boom has a separate one. Order only from the matching page.
Manual Section: Attachments p. 384Wire harness parts pages split at a serial break, unsure which harness listing fits my machine
Check the Electric Parts listings starting on page 316. Some CCD wire harness pages cover only serials 01101 through 01113, so read the serial number plate at the front of the machine, right side of the cab platform, per page 7. If that plate is unreadable, use the manufacturer's number stamped on the upper revolving frame.
