Component Documentation

When you are tearing down an L180, the machine P.I.N. and installed configuration determine which figure applies. This catalog maps the structural and mechanical composition of the loader section by section, then separates serial breaks, control types, flow packages, cab options, and regional variants. Assembly-level exploded views are paired with parts tables so the engine, fuel, electrical, power train, brake, hydraulic, chassis, cab, and attachment systems can be traced to their individual service parts.

• Engine and fuel: Coverage runs from the radiator/coolant recovery system, air cleaner, exhaust and aspirator, engine mounting, oil fill, block heater, and grid heater through the cylinder block, oil sump, crankshaft, connecting rods, pistons, camshaft/timing control, cylinder head and rocker shaft, intake and exhaust manifolds, turbocharger, oil pump and cooler, water pump, thermostat, and diagnostic sensor. Fuel-system figures cover the tank and shut-off valve, left- and right-side throttle controls, injection pump, injectors, injection piping and return, fuel filter, fuel pump, and fuel lines. The ASN engine section identifies engine overhaul kit P/N 8097550 and engine top-gasket kit P/N 8097551.

• Power train and brakes: The catalog covers tandem-pump mounting and internals, hydrostatic pump-to-manifold and drive-motor plumbing, the tandem-pump resonator, pilot-control-to-pump connections, ISO-pattern left-hand joystick valve kits, two-speed hydrostatics, standard and high-flow gear pumps, and single- and two-speed motor assemblies. It continues through final drive, transmission centering, Rexroth Pump AA22, pressure-relief valves, the internal gear pump, right- and left-hand rotary groups, the hydraulic control, control cartridge with orifice, and valve-section locking elements. Hydraulic brake figures distinguish standard, pilot-control, and on-road configurations.

• Implement and auxiliary hydraulics: Standard and high-flow bucket and boom circuits are separated from pilot-control and EH auxiliary arrangements. Coverage includes control-valve plumbing, hand- and foot-control valve assemblies, hydraulic oil cooler and bypass, mounting-plate shield and conversion kits, mounting-plate, bucket, and boom cylinders, filter and reservoir, connect-under-pressure couplers, secondary front and rear auxiliaries, and control-valve internals. Seal replacement kits, P.O. and EHPV spool-end groups, detents, check-valve groups, main relief valves, and control valve P/N 87658052 are indexed separately.

• Electrical, cab, chassis, and attachments: Electrical figures identify starter and alternator mounting, battery cables, standard and advanced instrument clusters, diagnostic plug, right- and left-hand consoles, the main harness and fuse block, engine/main/chassis electrical groups, two-speed and pilot-control harnesses, loader lockout, backup alarms, lighting, and heat and air-conditioning controls. Chassis coverage reaches the boom, boom lock and float kit, mounting plate, floor plates, standard and Deluxe Cab structures, doors, windows, demolition door, heater and air-conditioning assemblies, hand/foot/pilot controls, seats and belts, counterweight, noise-control equipment, Dirt/Foundry, Extended Low Profile, Utility/Light Material, and Manure/Slurry buckets, cutting edges, and pallet forks.

Named figure coverage includes the Radiator – Coolant Recovery System exploded view; Electric Cab – Main Harness and Fuse Block, Deluxe Cab view; Hydrostatics – Pump to Manifold view; Hydrostatics – Drive Motors to Manifold, Models With Pilot Control view; Control Valve EH Plumbing, Models With Pilot Control, EH Aux Control view; and Hydraulics – Oil Cooler Bypass, L180 ASN N8M464426 view. For an L180 shop, that means the Iveco package can be separated from the ASN FPT package before high-flow, two-speed, pilot-control, Deluxe Cab, or hydraulic mount-plate parts are ordered for a repair.

Specification and Reference Data

Each figure is organized by figure number, sequence code, page number, print date, description, and figure notes. The corresponding table supplies the REF callout, part number, quantity, year/serial applicability, part description, and additional identification notes. Repair-kit symbols show which items are supplied together. NSS marks parts not serviced separately; bracketed numbers identify parts unavailable as service items in that market; AR/X means as required; and BSN/ASN/BTW controls serial-number applicability. Right-hand and left-hand are defined from the rear of the basic loader looking forward, while attachment pages use the operator's normal seated position. New Holland also notes that production variations apply and that dimensions, weights, and illustrations may not represent every machine exactly.

The catalog records both metric and U.S. hardware dimensions and uses the number after a semicolon to identify hardware class or grade. Examples include 1/4"-20 Grade 5, M10 × 100 Class 8.8, and M20 × 1.5 × 100 Class 10.9 hardware, with NF, NPT, NS, ORB, ORFS, and LH/RH thread notation. Component-level examples include 480 mm (20 3/8 in.) and 518 mm fan variants, cylinder-head-gasket specifications SP=1.15 and SP=1.25, standard crankshaft main bearings plus −0.254 mm and −0.508 mm options, and tandem-pump overhaul seal and gasket kit P/N 140008A1, listed with 10 rings, 4 bearings, 20 O-rings, 6 gaskets, and 2 seals.

Specific part descriptions also carry pressure ratings. Backup-alarm control switches are listed as P/N 87029843 at 600 psi and the superseding P/N 87370805 at 2,000 psi. Option-dependent high-flow valves are identified as P/N 86520550 at 2,750 psi and P/N 87012669 at 3,250 psi; the catalog also lists replacement relief valve P/N 87021069 at 2,950–3,000 psi, main relief valve P/N 87610350 at 3,050 psi, and boom-float hydraulic valve P/N 9806765 at 110 psi. These values identify cataloged components; they are not pressure-adjustment instructions.

No shop-level step-by-step repair procedures are reproduced in this catalog. Several repair, service, and conversion-kit entries state that separate instructions are supplied with the physical kit, but those instruction sheets are not reproduced here. The catalog does not provide removal, disassembly, adjustment, pressure-testing, torque-sequence, or reassembly procedures, and it does not publish fluid fill capacities or hydraulic test instructions. It supports parts planning for engine overhaul, tandem-pump resealing, control-valve repair, cylinder service, fuel-injection component replacement, harness replacement, cab/HVAC repair, and attachment rebuilds by identifying the correct parts and kit contents; the applicable service publication is still required for the repair method.

Do not order from the nearest-looking figure until the machine P.I.N. is checked. The N8M464426 split changes the engine package, cooling module, engine mounting, fuel-injection equipment, electrical installation, and multiple hydraulic arrangements, so a hose, bracket, harness, pulley, or seal kit can appear correct and still be wrong for the loader. On control-valve work, identify the exact valve and spool-end group before loosening plugs or end caps; mixing a detent, check-valve, main-relief, EHPV, or seal-kit variant risks an internal leak or incorrect function. Do not substitute a fastener by diameter alone: forcing a near-match across inch and metric threads, or replacing SAE Grade 5 or Grade 8 or metric Class 8.8 or 10.9 hardware with the wrong specification, can damage threads, reduce clamp load, or disturb engine and pump alignment.

Keep in mind that replacing heavy machinery components involves significant mechanical hazards and pressurized fluids. Always verify load capacities and follow proper lockout/tagout procedures before turning wrenches based on these reference diagrams. The data presented here ensures you order the right hardware, but your shop's standard safety practices must dictate the actual tear-down and assembly.
