New Holland Kobelco E18SR, SK17SR-3, SK15SR-3 2007 Workshop Manual

If you’re wrenching on a New Holland Kobelco E18SR, SK17SR-3, or SK15SR-3 and the track won’t stay tight, or the travel motor is puking oil, you need the factory procedure – not some aftermarket summary that leaves out the idler adjuster preload. This 2007 workshop manual gives you exactly that: 54 pages of step-by-step removal, installation, disassembly, and assembly for the entire travel system. I’ve torqued more sprocket bolts than most people have eaten hot meals, and I’ll tell you right now – you skip the sequence on page 34-3 and you’ll be chasing leaks all week.

What’s Inside Chapter 34: Travel System

This manual is built around the travel system – chapter 34. It’s broken into two main sections: removal and installation (34.1) and disassembly and assembly (34.2). You get crawler removal and installation for rubber tracks, plus the optional steel track procedure. Every component is listed: slide plate, lower roller, front idler, idler adjuster, sprocket, travel motor, slewing bearing – even the adjustable crawler frame width. Page 34-33 walks you through tearing down the travel motor. That’s where most guys strip a seal lip because they don’t know the order. This manual tells you the order.

Rubber Crawler Removal – No Guessing

You got a blown track? The manual shows you how to relieve tension, remove the rubber crawler, and reinstall it with the correct alignment. It doesn’t say “remove retaining hardware” like a Chilton’s – it tells you what wrench size, which direction to loosen the idler adjuster grease fitting, and the exact procedure to walk the track off the sprocket. If you’ve got the steel track option, there’s a dedicated subsection starting after the rubber installation. I’ve seen guys ruin a new crawler because they tried to muscle it on without following the track path sequence. Don’t be that guy.

Torque Specs and Fluid Capacities – Why OEM Matters

Every fastener in the travel system has a factory torque spec. The manual doesn’t just give you a range; it lists the specific values for lower roller bolts, sprocket nuts, travel motor mounting hardware, and the slewing bearing bolts. These are Kobelco’s numbers, not someone’s guess. Using the wrong torque on a travel motor housing can crack the casting or cause a leak that takes hours to find. I’ve got a stack of aftermarket manuals that skip the idler adjuster preload spec – this one doesn’t. It also tells you the fluid type and capacity for the travel motor gearbox. That matters because the wrong viscosity eats bushings.

Does This Manual Cover Steel Tracks?

Yes. The table of contents lists a separate procedure for steel track removal and installation under 34.1.2.2. It’s clearly marked “STEEL : OPT” so you know where to look. Same level of detail – chain pitch, track shoe bolt torque, and the sequence for equalizing tension. If you’re swapping between rubber and steel, the manual includes the adjustable crawler frame width procedure (34.1.10) so you can set the correct stance. That section alone saves you from bending a track frame because you adjusted it wrong.

3 Systems You Can Fix with This Manual

• Travel Motor Rebuild: Full disassembly and assembly of the travel motor (34.2.1), including seal replacement and gear mesh clearance checks.
• Idler and Sprocket Replacement: Front idler removal (34.1.5), idler adjuster service (34.1.6), and sprocket removal (34.1.7) with all torque specs.
• Slewing Bearing Service: Removal and installation of the slewing bearing (34.1.9) – that’s the big ring that lets the cab spin. Miss the bolt tightening pattern and you’ll get a wobble.

Every section has a parts-name diagram first (34.1.1) so you know what you’re looking at before you touch a wrench.

FAQ

Does this manual cover the engine and hydraulics outside the travel system?

No. This specific manual is the travel system chapter only (chapter 34). For the complete machine, you need the full workshop manual set. That said, the travel section is extremely detailed – 54 pages on just the undercarriage and travel motor.

What year machines does it apply to?

First edition December 2006 for E18SR serial PU08-05001 and up. Updated January 2007 for SK17SR-3 same serial range.

Can I use this manual for a SK15SR-3?

Yes. The manual title includes SK15SR-3, and the preface lists it as applicable. The travel system components are essentially the same as the SK17SR-3.

Are torque values given in foot-pounds or Newton meters?

Both. The manual provides Imperial (ft-lb) and metric (Nm) values for every fastener. No conversion needed.
