Description

CASE 851EX Backhoe Loader Parts Catalogue — Print 47643704, Revision 03, October 2017

This is the full illustrated CASE 851EX Backhoe Loader Parts Catalogue issued under Print No. 47643704, Revision – 03, dated 10/2017. Inside you will find the complete group-by-group parts breakdown for the CASE 851EX machine, laid out so a technician, parts counter clerk or workshop can identify the correct component, the correct part number, the quantity used per assembly and the effectivity serial range for each line. Every major system of the machine is indexed and illustrated — the engine and component installation, the cooling system, the 2WD transmission, the rear axle, the front axle, the hydraulic system, the cabin, the body and structure, the buckets, the wheels, the electrical system, the stickers and tools section, plus the optional 4WD front axle, 4WD transmission, extendhoe, bottom dump bucket and HVAC cabin.

The catalogue follows the familiar group numbering used across the machine: groups 100 through 1700. Each group lists item numbers in the “Item No.” column, the part number, the description with technical spec where needed, the quantity per set or assembly, and the effectivity column showing the machine serial number in which the part is used. Exploded illustrations sit on the same page as the parts list so you can match a balloon number to the exact line item. A full numerical part index at the back of the document lists every part number, the page it is found on, and its reference number on that page — so even if you only have a part number in hand, you can jump straight to the correct group and illustration.

Why This CASE 851EX Parts Catalogue Belongs in Your Workshop

Anyone who has ordered a part for a backhoe loader from memory alone knows the cost of getting the part number wrong: a week of downtime, a return shipment, and a machine sitting idle on site. The CASE 851EX Backhoe Loader Parts Catalogue removes that guesswork. Every assembly on the machine is broken down into its individual components with the exact part number, quantity per set, and effectivity serial range. You can look up an engine mounting bracket, a stabilizer cylinder seal, a swing tower bushing, a bucket tooth, or a cab door lock by group or by the numerical index at the back — and see the illustration right alongside the list to confirm what you are ordering.

Because this is the parts catalogue the parts desk uses, it is the same document a dealer counter references when you phone in an order. Having it on your own device means you can confirm the correct part number before you call, verify what is included in an assembly kit (such as the 47481288 brake repair kit or the 47895039 main hydraulic pump seal kit), and check the effectivity serial number to make sure the part fits your specific machine before it ships. For workshops running several 851EX backhoes, the serial-range data alone is worth the price of the download — it prevents fitting a part intended for an earlier or later build.

The catalogue covers the complete machine, not just the mainstream assemblies. That includes the optional 4WD front axle and 4WD transmission, the Extendhoe, the 6-in-1 bottom dump bucket and the HVAC cabin, so whether your 851EX is a standard 2WD unit or a fully optioned machine, the relevant group is present. Sections for electrical harnesses, stickers and warning symbols, and the recommended tool kit round out the document. Torque-critical fasteners, washers, O-rings, seals and shims are all listed individually — exactly the small parts that get lost on a rebuild and hold up a job when they are not on the shelf.

Delivery is instant. After payment the PDF is available immediately — no shipping, no waiting for a disc, no customs delay on an overseas order. Open it on a laptop in the workshop office, a tablet on the machine, or a phone in the yard. Print the group you are working on and take the page to the bench. The file works on any device that reads PDF, and the group numbering and exploded views are laid out so you can navigate quickly even on a small screen. If you maintain, rebuild or restore a CASE 851EX Backhoe Loader, this parts catalogue is the reference that keeps your parts orders correct the first time.
