Link-belt LS-98A Operators Manual – 122 Pages of Factory Crane Specs

I’ve seen too many crane operators skip the book and wreck a boom. The Link-belt LS-98A Operators Manual is what you need sitting in the cab. 122 pages, every lever pull and grease point documented by the factory. If you’re running a 98A on a job site, this is your safety insurance. OEM torque specs, hand signals, load lowering procedures – all inside. You don’t guess on a crane that lifts twenty tons.

Quick Reference Page and Operating Instructions – Section 1

Section 1 covers more than just start-up. Page 3 of the manual shows the Quick Reference Page with the full TOC. You get operating instructions for the LS-98A and the entire 98-118 series. Crane operation, dragline, clamshell, trench hoe – each attachment has its own subsection. Hand signals are on page 1-25. If you ever need to jack the machine with the boom mast, that procedure is on page 1-37. You also get the procedure for shutting down the crane and load lowering with torque converter and lowering clutches. Missing that step can drop a load.

Protective Maintenance and Lubrication – Chapter 2

Lubrication intervals are not suggestions. Chapter 2 lays out where to grease and how often. This isn’t a generic chart – it’s Link-belt’s original factory schedule. Every pivot pin, sheave bearing, and clutch linkage gets a spec. You’ll also find fluid capacities in imperial units. No metric conversions needed. If you skip this chapter, your machine eats bushings. I’ve seen it.

Periodic Adjustments – Section 3: Don’t Skip These

Friction clutches, brakes, swing pinion clearance – all in section 3. The manual tells you which shims to pull and which clearances to hold to thousandths. One page covers brake band adjustment for the 98A. The OEM procedure is the only one that keeps your crane safe. Aftermarket books leave out half the steps. This one doesn’t.

SoM Control System and Attachments – Sections 10-13

The S-o-M Control System is the heart of the LS-98A’s driveline. Section 10 covers its operation, safe engagement, and troubleshooting. Attachments include trench hoe (section 11), shovel (section 12), angle boom and tubular boom (both in section 13). Each section starts with attachment-specific rigging and capacities. If you’re swapping from crane to hoe, you need those pages.

Specifications and General Information – Section 14: The Final Authority

Section 14 holds the crane rating capacities, engine specs, and weight data. This is the section you check before lifting near the limit. It also includes serial number location info – page 1 tells you where to find it if the plate is gone. Machine serial number is stamped on the right-hand boom foot mounting lug for cable cranes. For hydraulics, it’s below the boom hoist cylinder lugs. Use that number when ordering parts.

Who Needs This Manual?

Any owner-operator of a Link-belt LS-98A, LS-98, or 118-series crane. Home garage enthusiasts? Not so much. This is for heavy equipment. Crane operators, riggers, and shop mechanics who need the factory word. Also for insurance inspectors who require OEM documentation on site. If you work on these machines, you need this manual open on the toolbox.

Source Authenticity: Factory OEM vs Aftermarket

This is not a reprint or a scan from a third-party. It is the original PDF from FMC Corporation (Crane and Excavator Division, Cedar Rapids, IA). The manual says: “Read this book and make sure you understand it before operating, lubricating, or adjusting the machine.” That’s the factory talking. Aftermarket books often combine models incorrectly. This one is specific to the LS-98A with Book No. 102. You get the real torque specs and correct hand signals.

Does the Link-belt LS-98A Operators Manual cover serial number ranges?

Yes. The manual instructs you to note the serial number from the capacity plate or the Crane Rating Manual inside the cab. If the plate is missing, the number is stamped on the upper revolving frame. The manual includes a blank line on page 1 for writing in your machine’s serial number.

What torque specs are included in this manual?

Torque values for critical fasteners are provided in the Periodic Adjustments chapter (section 3) and the specifications chapter (section 14). Values are given in foot-pounds. Specific torque for boom foot pins, swing shaft retention bolts, and outrigger lock nuts are listed with the associated adjustment procedure.

Is this manual only for crane operation, or does it cover attachments too?

It covers crane operation plus trench hoe, shovel, angle boom, tubular boom, and hydraulic bucket attachments. Separate sections exist for each attachment with rigging and operating procedures. The dragline and clamshell operations are also included in section 1.

Can I use this LS-98A manual on other Link-belt models?

No. The 98A has unique control system and specifications. There is a related manual for the Link-belt HTC-8675XP II Operators Manual – 282 Pages Factory Specs and another for the Link-belt DS350, 1225, 1229 1997 Operators Manual – OEM Factory Specs. The Link-Belt LS98 98 118 Series Operator’s Manual covers the 98 and 118 series broadly but does not replace the LS-98A specific book. Always use the correct manual for the serial number.

If your job involves working with mechanical systems, understanding the basics of a Manual Transmission can help you diagnose driveline issues. The LS-98A uses a torque converter and manual clutch combination for certain operations – the same principle as a Manual Transmission in a truck. But the factory manual gives you the exact adjustment specs, not general theory.

Stop relying on faded photocopies or internet forum guesses. Access the Factory Manual – the official Link-belt LS-98A Operators Manual – and have the real specifications at your fingertips. 122 pages of OEM data, ready to open on your tablet or print for the cab. Your machine’s safety depends on it.
