CNH America E50 2005 Parts Catalog – Factory Part Numbers You Can Trust

Ever stood at the parts counter with a worn-out number scribbled on a rag, hoping the counter guy can cross-reference your E50? That guesswork burns time and money. This catalog is the OEM bible for the CNH America E50 2005 compact crawler excavator – 458 pages of factory part breakdowns, exactly what the dealer uses. No aftermarket reinterpretation, no third-party reprints. Just the original 87360688 NA publication.

Engine and Fuel System Coverage

Section 1-01 of the Engine section (page 25 in the TOC) lists every component from the mounting hardware to the accessory drive. The Fuel system gets its own dedicated treatment: FUEL LINES (page 52), FUEL TANK (CANOPY and CAB variants on pages 59-60). Need the part number for the injector return line on a cab model? That exploded view lives under “FUEL TANK (CAB)” on page 60. The diagrams are clean – each part circled with a reference number tied directly to the factory parts list at the bottom of the page.

Hydraulic Piping: Pump to Control Valve

Hydraulic system leaks nightmare. This catalog breaks down every hard line and hose in the PUMP/CONTROL VALVE PIPING sections (pages 92, 100, 104, 110). Included are the NIBBLER & BREAKER variants for those running attachments. If you are rebuilding a control valve or replacing a cracked hose, the exact routing and o-ring size are in the illustrated parts list. No generic “use this if it fits” – these are OEM part numbers down to the last clip.

Cab Components and Control Systems

The CAB – COMPONENTS section (pages 180-01 and 2-01) covers everything from the floor pan to the control levers. For the operator station, sections like CONTROLS (CANOPY), CONTROLS (CAB), and CONTROL LINES (MULTI) give you the full assembly breakdown. Has a joystick linkage started binding? The exploded view under “CONTROLS” on page 128 shows each ball joint and bracket. That level of detail prevents ordering the wrong cable or bracket.

Who Actually Needs This Catalog?

This one is for the owner-operator who maintains their own E50, the small fleet manager with multiple CNH machines, and the shop tech who refuses to rely on aftermarket interchange lists. If you swapped in a reman engine and need the correct fuel line routing for the CANOPY version, the diagrams on pages 52 and 59 are your blueprint. Also useful for rebuilding a swing hydraulic motor – the SWING HYDRAULIC MOTOR section (page 74) lists every seal and bearing. No more trial-and-error on parts that cost $200 each.

Why This OEM Manual Beats Aftermarket Versions

Printed in November 2005 by CNH America, this is the first edition factory parts catalog – same book the dealer pulls up on the counter. Aftermarket catalogs often scan older editions and miss later supercessions. Here, every revision history is baked into the document (page 2). If a part was updated mid-production, the catalog notes it. 458 pages, no recycled content, no generic illustrations. For the E50, this is the source of truth. For related machines, see the CNH America 621E 2007 Parts Catalog – 896 Pages of OEM Specs or the CNH America LV80 2002 Parts Catalog – 638 Pages OEM. For the updated SR model, there is the CNH America E50SR 2007 Compact Crawler Excavator Parts Catalog.

6 Systems at Your Fingertips

The table of contents lists over 60 sub-sections covering the Engine, Fuel system, radiator, air cleaner, muffler, control valve, swing hydraulic motor, lubrication lines, control lines, cab components, and more. Everything from the bracket assy swing (NIBBLER & BREAKER) to the floor cab. If you own an E50, owning this catalog means never paying dealer markup on a part number lookup again.

Does this catalog include service procedures or only part numbers?

This is a parts catalog – exploded views and part numbers only. For service procedures, you need the separate service manual. But for ordering, this is all you need.

Will this work for a 2006 E50?

Yes. The manual states the unit first became available 01-2006. It covers production from that date onward. Check the revision history on page 2 for updates.

Are torque specs included in this parts catalog?

No. This catalog lists parts and their OEM numbers. Torque specs are in the service manual. But the fuel line routing diagrams on pages 52 and 59 show exact part numbers – that saves you ordering the wrong hose.

How do I find a specific part number for the control valve piping on the nibbler variant?

Turn to section “PUMP/CONTROL VALVE PIPING (NIBBLER & BREAKER)” – pages 104 and 110. The exploded view is keyed to a numbered parts table. Match your machine configuration (canopy vs cab) to get the right hose assembly number.

This catalog sits on the shop bench, not the shelf. Spattered grease, dog-eared corners, and pencil marks are signs of a well-used parts book. For anyone who has tried to cross-reference a CNH part number through generic databases, this OEM file ends that frustration. Access the Factory Manual now and keep your E50 running with the right parts the first time.
