ELME 558 2004 Service Manual – Factory Specs, Not Guesswork

You pull the ELME 558 extension cylinder out of the spreader, and the seal kit arrives. Now you need the correct reassembly sequence and the torque for those gland nuts. Grab the aftermarket PDF you found online, and it says “tighten to specification” – but gives you no number. That is exactly why you stop looking at free documents and buy the 51-page factory document. This is the real 2004 Service Manual from Elmhults Konstruktions AB, the people who built the damn thing. It is not a reprint, not a generic copy. It is the original PDF.

Section B110-150 covers the extension cylinder service instruction. That is where you find the disassembly steps, the order of the seals, and the critical torque values for the cylinder end caps. Page 3 lists the build index and directs you to the exact section you need. Page 4 gives you the parts breakdown for the extension cylinder assembly, part number E779 065, so you can order the right seals the first time. No hunting through parts catalogs.

Extension Cylinder Service: B110-150

The cylinder is the heart of the spreader’s extension function. The service instruction in B110-150 walks you through each step: removing the cylinder, disassembling the piston from the rod, replacing the wear rings and seals, then reassembly. It tells you the tools you need – a seal driver, a torque wrench capable of reading in Nm (don’t use ft-lb conversions unless you trust your math). The manual gives you the OEM torque spec for the piston nut and the gland. You do not have to guess.

Every time I see a cylinder leak on a 558, nine times out of ten it is because someone reused a seal or over-torqued the gland. The factory manual prevents that. Follow the service intervals in B110-017 Maintenance Instruction – it tells you when to change hydraulic oil and filter, when to inspect the cylinder for scoring. Save yourself a comeback.

What’s in the Wiring Diagram on Page 3?

Page 3 shows Section C Diagrams: hydraulic symbols, hydraulic schematic (772 163), and the wiring diagram (782 037). The wiring diagram is the actual factory drawing – not a redrawn version from some third party. It labels every wire color, connector pin, and ground point. If you are chasing an indicator light failure or a solenoid that won’t trigger, you start with this diagram. The electric schematic (782 036) covers the control logic for the sideshift and extension valves. Without it, you are probing wires blind.

I have seen mechanics spend half a day tracing a bad ground on a spreader because they used a generic schematic that didn’t match the pinout. The ELME factory document eliminates that. Use it.

7 Sections of Factory Data

Seven sections in this 51-page manual: User Instruction (A), Service Manual (B), Diagrams (C), Mechanical Parts (D), Hydraulic Parts (E), Electrical Parts (F), Special Parts Optional (G). Each section is a chapter you can jump to based on your repair. The parts sections list exploded views with item numbers and part numbers – D781 282 Extension beam arrangement, E776 761 Sideshift cylinder assembly, F782 087 Electrical system. You can order the exact bolt, seal, or valve without measuring.

The hydraulic parts section (E) includes the Parker fittings list (E779 735) – so you get the correct O-ring face seal or JIC fitting. No mixing metric and imperial threads because you lost the old fitting. The mechanical section (D) gives you the wear pad dimensions (D781 190, D782 086, D783 745) – you can check clearance before you bolt the carriage back on.

Lubrication Chart and Maintenance Instructions

B110-148 Lubrication chart: tells you which grease points, what grease type, and how often. B110-017 Maintenance instruction covers daily, weekly, monthly checks. This is the kind of information that prevents premature wear on the extension beam slides and the end beam assembly (D782 177). The manual treats you like a professional: it expects you to follow intervals, not guess.

I ran a six-bay shop for two decades. The techs who ignored lube charts always had the most comebacks. Do not be that guy.

OEM Documentation: Why Aftermarket Manuals Fail

Look at the OCR excerpt: “ELME SWEDISH SPREADER SYSTEMS” on page 1. That is the original header. The build index on page 3 shows the exact model revision (Build Index No. 1-1151). Aftermarket sources often strip out the build index, leaving you with a manual that might cover a different revision. Then you order parts based on the wrong section, and the spreader sits dead while you wait for the correct part. This manual is the OEM scan – it retains every page, every revision mark (02-05 11-04). You can verify you have the right version for your serial number.

For other ELME spreader models, check these related factory manuals: ELME 812-818 2005 Service Manual – Factory Specs & Repairs, ELME 952 2004 Service and Parts Manual, and ELME 7036 Service and Parts Manual. All OEM, all factory scans.

If you want to understand the fundamentals of spreader transmissions or driveline components, Wikipedia has solid overviews on Manual Transmission and Manual Transmission. But for the ELME 558 specific wiring and hydraulics, this factory manual is the only source you should trust.

FAQ – ELME 558 Service Manual

Does this manual include torque specifications for the cylinder?

Yes. Section B110-150 lists the factory torque for the piston nut and gland. Use a quality torque wrench set to Nm.

Is this a scanned PDF or a reprint?

It is an OEM scan of the original 2004 factory manual, 51 pages, with all sections A through G. No reprint, no third-party editing. You get the exact document the Swedish engineers released.

Can I use this manual for the ELME 558 with a different build index?

This manual is for Build Index No. 1-1151. If your serial number matches that build index, the parts and procedures are correct. If not, cross-reference the major assemblies – the extension cylinder and hydraulics are often shared across indexes, but always verify part numbers from Section D and E before ordering.

What wiring information is included?

Section C provides the wiring diagram (782 037) and electric schematic (782 036). Both are factory-original drawings with wire colors, connector labels, and pin assignments. You also get hydraulic symbols and a hydraulic schematic (772 163).

You are rebuilding a 558 spreader. You want it back in service without a second tear-down because you used the wrong torque or the wrong part number. This factory manual gives you the exact information Elmhults Konstruktions AB printed for their own service network. Stop guessing, stop relying on forum posts that may be for a different revision.
