John Deere 9505, 9510, 9511 Parts Catalog

If you’re wrenching on a John Deere 9505, 9510, or 9511 backhoe, you know the feeling of staring at a hydraulic valve cluster with no clue which port goes where, or digging through aftermarket parts lists that don’t match the casting numbers on your bucket cylinder. This catalog fixes that. It’s the same 166-page binder that John Deere sent to dealers in 1980 – PC3170. No generic redraws, no third-party interpretations. You get the actual part numbers, exploded views, and the exact hardware specs that came off the assembly line.

Boom and Bucket Cylinder Breakdowns

This catalog gives you separate sections for Boom Cylinder – CD 7168 and Boom Cylinder – CD 7169, each with its own part number table. Same for bucket cylinders – CD 7171 and CD 7172. You’ll find the piston seal sizes, rod wiper part numbers, and the retaining ring specs. For bucket pins, the catalog covers 20″, 24″, 30″, and 36″ widths. These are the same dimensions used on the factory buckets – no guessing whether a 7/8″ pin fits the 30″ bucket. If your cylinder is leaking down, flip to the Boom Cylinder section and order the right seal kit the first time.

Control Valve Sections with Variants

Backhoes came with different valve configurations depending on the year and option package. The catalog lists Control Valve-CD 7128 and Control Valve-CD 7129 separately, plus a dedicated Control Valve (With Extendible Dipperstick) and its housing assemblies. There’s even a section for Control Valve Housing and Cover – CD 7177 through CD 7180. Each exploded view shows every spring, poppet, and O-ring. If you’re rebuilding a swing control valve or a stabilizer control valve, the part numbers are right there – no cross-referencing aftermarket catalogs that skip the internal snap rings.

Cylinder and Valve – What the Parts Index Covers

The Parts Index at the back (page number is in the manual) uses alphanumeric codes linked to every drawing. So if you need the Relief Valve -CD 7144 or the Check Valve for the crowd circuit, you can look it up by the CD number. The catalog also includes Oil Lines (Boom and Crowd Circuit), Oil Lines (Stabilizers and Swing Circuit), and separate oil line drawings for machines with the extendible dipperstick. For hydraulic plumbing on models that share components with JD 400A, JD 310, JD 410, JD 450A, or JD 500C, there are dedicated subsections. That means you can order the correct hose assembly without measuring the old one – especially useful when the crimped fitting has the original part number stamped on it.

Does This Manual Cover the Fuel System and Engine?

This is a parts catalog, not a service manual. It focuses on the backhoe attachment – the boom, dipperstick, buckets, stabilizers, and the hydraulic control system. Engine components like the valve train, fuel injection pump, or cylinder head are not included. If you need engine specs, grab the factory service manual for the tractor model. But for every pin, bushing, seal, hose, and valve spool on the backhoe itself, this catalog is the authority.

3 Reasons OEM Documentation Beats Aftermarket Reprints

First, every part number in this catalog traces back to John Deere’s own engineering drawings – no typos, no supersession errors. Second, the serial number ranges are printed on the parts lists, so you can tell if your 9511 uses the early or late boom pivot. Third, the Decals/Accessory section includes correct decal part numbers for safety warnings and model identification. Aftermarket catalogs rarely include decal data. Access the factory manual and you’ll avoid ordering the wrong stabilizer pad or mixing up the Boom Pivot pin with the Bucket Pins.

Will this catalog help me rebuild a boom cylinder?

Yes. The Boom Cylinder – CD 7168 and CD 7169 sections show every seal, ring, and rod part. You’ll need the CD number stamped on your cylinder to find the exact page.

I have a 9511 with an extendible dipperstick. Are the oil line drawings different from the standard model?

The catalog has separate subsections labeled “Oil Lines (With Extendible Dipperstick)” and “Oil Pressure and Return Lines (With Extendible Dipperstick)”. They show the extra hoses and fittings for the dipperstick extension cylinder and the crowd circuit. Use the CD numbers on the drawing – they match the hardline routing in the machine. Also check the Extendible Dipperstick Cylinder and Extendible Dipperstick Housing sections for the mounting brackets and pins. Those pages are critical if you’re replacing the entire assembly because the bushing part numbers are different from the standard dipperstick.
