Link-belt LS118 1992 Parts Catalog

I’ve watched guys pull a boom hoist cylinder off a Link-belt LS118 and then spend an hour on the phone trying to match a seal kit because they didn’t have the serial number. That’s billable time you don’t get back. This Parts Catalog from 1992 puts the factory part numbers in your hand. It’s not a repair manual—it’s the parts bible. If you’re wrenching on an LS118 and need to order anything from a filter to a final drive gear, you need this.

Machine Serial Number: The First Step

Page 1 of this catalog tells you exactly where to find the machine serial number on the Link-belt LS118. On cable cranes it’s on the right-hand boom foot mounting lug. On hydraulic excavators it’s stamped below the boom hoist cylinder lugs. The manual says to always furnish that number when ordering parts. I’ll add: if you don’t, you’re rolling the dice. The parts explosion in this 144-page

7 Systems Covered – But Not Repairs

This catalog covers the upper revolving frame, boom, stick, hydraulic system, final drives, cab, and attachments. It’s arranged by assembly group with exploded diagrams and corresponding part numbers. What it won’t do is tell you how to rebuild a pump or set track tension. That’s what the service manual is for. The parts list is for ordering. If you need a new control valve spool, you get the right one because you matched the part number from these pages. No guesswork.

Operator’s Manual Quick Reference – What Page 3 Tells You

Page 3 shows a quick-reference to the operator’s manual for the LS118 series. It lists sections like “Protective Maintenance And Lubrication” and “Periodic Adjustments.” That page alone warns you that this machine requires regular maintenance and that the parts catalog is part of the system. You ignore that reference and you’ll be chasing leaks that shouldn’t exist. The parts catalog gives you the o‑ring size and material; the operator’s manual tells you when to change it. Together they keep the machine running.

Parts Catalog vs Aftermarket: Know the Difference

I’ve seen aftermarket parts catalogs that list “compatible” part numbers for the LS118. Compatible means someone thought it looked close enough. The factory Link-belt catalog uses the exact OEM numbering from the engineering release. For example, the Automotive Industry Overview might talk about standards, but in this crawler crane the pin sizes are unique. You don’t get a second chance on a hoist drum bearing. The OEM catalog is the only source I trust for part numbers, and this one is a direct scan of the 1992 original print—no aftermarket reinterpretation.

Does This Manual Cover the Entire Machine?

Yes, in terms of replaceable parts. It includes the trench hoe attachment, shovel attachment, angle boom, and tubular boom. The serial number applies to the whole upper and undercarriage. If you’re working on a 1992 Link-belt LS118 with, say, serial number 12345, you use the serial-break tables to find which diagram applies. The catalog doesn’t cover every nut and bolt—it covers assemblies and service parts. You get the factory part number, quantity, and sometimes a note about supersession. That’s enough to order from any Link-belt dealer or parts supplier.

Frequently Asked Questions

Does this parts catalog include repair procedures or torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque specs and rebuild procedures are in the separate service manual.

How do I find the correct part number for my LS118?

First, locate the serial number on the machine as shown on page 1 of the catalog. Then use the table of contents to find the assembly group (e.g., “Track Frame”). Each part in the exploded view has a reference number, and the list next to it gives the Link-belt part number. Cross‑reference the serial number range to ensure the correct part.

Will this work for a 1991 LS118?

If the serial number falls within the ranges covered in this 1992 catalog, yes. The catalog covers multiple serial breaks for that model generation. Check the introduction for the exact serial ranges.

Is this a PDF or a printed copy?

It’s a digital download of the factory scan. You get the original 144 pages in PDF format, ready to print or view on your tablet in the shop.

I’ve been turning wrenches on Link-belt machines long enough to know that a misordered part costs more than the manual. This 1992 Parts Catalog for the LS118 is the one I keep in the shop iPad for when a customer drops off a cable crane. Don’t waste your time guessing part numbers. Download the Factory Manual and get the right parts the first time. Also check out the Link-belt ABS-78A, TC-78A, API-78A, TC-78B Parts Catalog – OEM 142 Pages, the Link-Belt RTC-80130 II 2011 Parts Catalog, and the Link-Belt HTC-86100 2011 Parts Catalog if you work on those models. And for general industry context, the Automotive Industry Overview may not cover construction cranes, but understanding OEM vs aftermarket applies to every machine.
