Palfinger PK 8500 2003 Parts Catalog – Factory Parts Data

Description

Palfinger PK 8500 2003 Parts Catalog – if you are tired of guessing which bracket fits which arm, this is the one piece of paper that will cut your bench time in half. I have been wrenching on truck cranes for 28 years, and I can tell you that the difference between a job that takes two hours and one that takes all afternoon is often a missing part number. This 135-page factory catalog from 2003 gives you the exact exploded views and part codes Palfinger used on the assembly line. Skip the fuzzy, third-party scans that leave out critical details. This is the original OEM print, straight from the source.

Palfinger PK 8500 2003 Parts Catalog: System Group Layout

The table of contents organizes the crane into twenty-plus system groups. You get base and console sections (Kransockel, Konsole), traversing gear (Schwenkwerk), piping and central lube (Verrohrung-Zentralschmierung), then the control valve groups for stabilizers, F controls, and RC remote control. Each subsystem has its own set of numbered part diagrams. For example, the Ausleger (extension box) sections cover R1, R2, R2X, and R3X booms with separate hydraulic routing sheets. Page 1 lists the variant designations — R1, R2, R2X, R3X, STZS, STZY, plus the optional external tank and RC400 remote. That page alone will save you from ordering the wrong stabilizer ram.

Crane Base and Console Assembly Sections

These are the foundation of the crane. The catalog breaks down every bolt, bushing, and bracket in the base frame (S111SGA-010.0100 through 010.2100). If you are rebuilding a PK 8500 from the ground up, you will spend time here. The diagrams show each part with a callout number. Cross-reference that number with the parts list next to the drawing. Do not assume the part fits just because it looks close — use the callout. I have seen guys grab a similar pin from a PK 7501 and end up with a sloppy fit that wore out in six months. The factory drawing does not lie.

Which Parts Are Covered in the Steering and Control Sections?

The Verrohrung-Steuerung sections (piping for F, RC, and RSQ 240 control valves) are covered in S111SGA-030.0100 through 030.0500 and S111SGA-031.0100. These are the hydraulic lines that make the crane move. Each pipe assembly has a separate part number. If you are replacing a leaky hose or a damaged fitting, you need the exact routing diagram. The catalog also includes the overload protection valves (overload protection-OSK-F and OSK-RC) and the limit switches for rotation and transport position. Every electrical component is listed under Elektroteile (section S111SGA-070.0100 through 070.0700). That includes the entire wiring harness for the control panel and the stabilizer support monitoring.

20 System Groups from Base to Stabilizers

The stabilizer (Abstützung) system alone takes up multiple sections: S111SGA-040.0100 through 040.0300 for STZS, then S111SGA-050.0100 and 050.0200 for STZY. Each stabilizer ram has its own parts list and hydraulic routing diagram. The oil tank (Öltank, 70-liter) is covered in S111SGA-020.0100. You get the complete tank assembly, including the filter and return line components. The control valve blocks for the stabilizers and the main functions are broken out separately — do not try to interchange parts between the STZS and STZY without checking the callout numbers. They look similar, but the porting is different.

Get the Right Part Numbers from the O-Ring Table

There is a dedicated O-ring table (O-ringtabelle) and a hose fitting section (Schlaucharmaturen) at the back of the catalog. If you are rebuilding a cylinder or replacing a seal, you need those O-ring dimensions. Third-party cross-reference charts are often wrong for metric Palfinger seals. The factory table gives you the exact ID, OD, and cross-section in millimeters. Match that to your dash number, and you will not be chasing a leak after reassembly. The same goes for the hydraulic fittings — they are listed with part numbers for each adapter, tee, and elbow.

Factory OEM Documentation vs Aftermarket Reprints

I have seen aftermarket parts lists that combine schematics from three different years into one blob. That is a waste of ink. This manual is from 2003 and matches the PK 8500 built in that year. The indexing uses Palfinger’s own system: db-ekat-s111sga and db-ekat-pvg32 for the control valve set. If you try to use a generic parts book, you will end up with a part that is superseded or never fit in the first place. Spend the time to get the factory print. It will pay for itself on the first order.

Skip the aftermarket junk.

Frequently Asked Questions

Does this manual include part numbers for all hydraulic components?

Yes, part numbers are listed for each subsystem.

How do I identify the correct part for my PK 8500 variant?

Use the variant designations on page 1 — R1, R2, R2X, R3X, STZS, STZY. Then find the corresponding section in the TOC. For example, if you have an R2X extension, look under Ausleger-R2X (section S111SGA-010.1300). The exploded diagram will show the part callout. Cross-reference that callout with the parts list on the same page. The catalog does not sort by generic numbers; it uses the factory assembly order. Follow that order and you will get the right part every time. Do not skip the O-ring table if you are replacing seals — the dimensions are exact.
