All 85 pages of this Yanmar V4-5D (US), 4TNV88-NKAH Parts Catalog (OEM #0CS10-M47800EN) exist for one purpose: putting the right part number in your hand before you call the dealer. Organized from silencer and air cleaner through drivetrain, axle assemblies, hydraulic piping, lift arm, and bucket, every system on your 2006 wheel loader gets its own exploded view with OEM part numbers, assembly callouts, and cross-reference data. Inside you'll find component breakdowns for the HST motor, control valve, power steering cylinder, ROPS cabin, and cab electrical; each assembly laid out so you can identify exactly what you're ordering. Cross-reference a 25X15 bush or a 1AP16.0 O-ring by number and confirm fitment before the parts truck rolls. No more guessing at part names or ordering the wrong supersession. Bookmarked by assembly, this PDF opens on any device. Pull it up at the counter and order with confidence.

Yanmar V4-5D (US), 4TNV88-NKAH Common Problems This Manual Covers
Yanmar V4-5D hydraulic lift cylinder leaking, need correct seal kit part number p. 57
Check the Lift Cylinder exploded view on page 57. The seal set is listed separately from the cylinder assembly, locate it in the parts list and confirm the seal set designation matches your serial number range using the Effective Machine No. table starting on page 2. Cross-reference with the suction filter parts on page 69 to rule out contamination damage before ordering seals.
Manual Section: Lift CylinderPower steering cylinder leaking or binding, unsure which seal kit to order p. 59
Open the Power Steering Cylinder diagram on page 59. The piston seal set is spec'd at 60A, verify that designation in the parts list before ordering. Confirm your machine's serial number falls within the listed range on page 2, then cross-reference with the Steering Unit parts on page 66 to identify any associated fittings or O-rings that should be replaced at the same time.
Manual Section: Power Steering CylinderHydraulic oil filter needs replacement, can't identify correct filter element part number p. 69
Go to the Filter & Pipe Fitting diagram on page 69. The line filter element is listed separately from the filter body assembly. Also check the Hyd. Oil Tank diagram on page 68, the suction filter is a distinct part from the line filter and both may need replacement during a fluid service. Confirm both part numbers against your serial number range before ordering.
Manual Section: Filter & Pipe FittingRadiator hose or clamp leaking coolant, need part numbers to order replacements p. 14
Reference the Radiator assembly diagram on page 14. Hoses, clamps, and the drain cock assembly are all itemized separately in the parts list. The pipe dimensions listed are 7x130 mm, verify your hose matches before ordering a replacement. Check page 13 for engine mounting brackets that route near the coolant system, as adjacent parts are often replaced together.
Manual Section: RadiatorBattery cable or wiring harness corroded or damaged, need correct replacement part p. 17
Open the Battery section on page 17 to find cable assemblies, cord harnesses, holder, and clamps as individual line items. Identify which component failed before ordering. For broader electrical issues, cross-reference the Wiring diagram on page 18 to locate the specific harness segment, and check page 19 for relays, switches, and lamps. Replacement bulbs are rated 12V-34W per the parts list on page 20.
Manual Section: BatteryDump cylinder won't hold load, need seal kit part number for rebuild p. 58
Find the Dump Cylinder exploded view on page 58. Locate the seal set line item in the parts list and note the part number exactly as printed, seal kits for lift and dump cylinders are not interchangeable despite similar appearance. Cross-reference with the Hyd. Oil Piping (Loader) diagram on page 72 to identify any hose or fitting part numbers needed if the leak is traced to a connection rather than the cylinder itself.
