Sandvik 00855-R1 Service Manual – Factory Specs for Heavy Drilling Equipment

I’ve seen guys lose fingers because they skipped the safety chapter on a rig like this. The Sandvik 00855-R1 Service Manual is what you need on the bench if you’re pulling wrenches on this drilling equipment. It’s 344 pages of factory procedure—not some aftermarket copy that guesses at torque values. The original PDF file runs from introduction through the last maintenance table, and every spec came from Sandvik’s engineering floor. You don’t get that from a third-party reprint.

Safety Section: Read It Before You Hit the Shop Floor

Page 11 kicks off the safety chapter. That’s where you’ll find emergency stop procedures, PPE requirements, and the warning signal layout for the core drill, wireline winch, power unit, and control panel. Section 2.6 goes through each piece of equipment—the core drill, wireline, power unit, control panel, water pump—and lists the specific hazards. If you’re used to skipping to the wiring diagrams, don’t. The hydraulic system section on page 28 covers safe pressure release and lockout steps. I’ve seen too many techs blow a line because they thought they knew the system. This manual forces you to slow down and confirm.

Hydraulic System: Torque Specs and Test Procedures

Page 52 starts the hydraulic system description. Section 3.8 breaks down the directional valve, selector valves for high/low speed and pipe entry/exit, the ball valves for the chuck and pipe clamp, and the rotation motor. Section 1.4.10 outlines the hydraulic system test procedure—how to verify pressure and flow without risking components. Torque values for hydraulic fittings are listed in the maintenance tables. You won’t find those in a generic manual. This is Sandvik’s own data. If you need the charge pressure spec, you’ll find it in the technical data chapter. Everything is in metric, but I convert to ft-lbs on my bench. The manual gives you the factory number; you do the math.

344 Pages of OEM Procedure – No Aftermarket Guesswork

Aftermarket manuals leave out steps. This one doesn’t. It’s the same document Sandvik hands to their own service techs. The table of contents covers introduction, safety, technical description, and maintenance. Every subsection is numbered and cross-referenced. When you see a torque spec in this manual, it came from Sandvik’s engineering, not from a forum post. The difference between a stripped thread and a properly torqued bolt is the spec. OEM documentation eliminates the guesswork. For related Sandvik equipment, check out the Sandvik TORO 7 2006 Service Manual – Factory Specs & Procedures or the Sandvik Tamrock Secoma S.a.s AXERA 5 THC560 2005 Service Manual for similar drilling platforms. If you’re working on loaders, the Sandvik LH203 2010 Operators Manual – Factory Specs & Safety covers those systems.

Maintenance Program: Daily Checks and Scheduled Overhauls

Page 72 gives the programmed maintenance schedule. Page 74 covers daily checks. This is where most breakdowns get caught early. Section 4.4 tells you how to clean the air bleed plug. Section 4.5 walks through filter inspection, oil level check, and hydraulic fluid fill. You’ll also find lubrication intervals for guide rails (page 79), rotation unit chuck and bearings (page 81), feed bar chains (page 84), and chain tension adjustment (page 86). Water pump oil level check is on page 95. The schedule is laid out by hour meter intervals. If you follow this, the rig stays running. Skip it, and you’re rebuilding a hydraulic motor at double the cost.

Technical Description: Know Your Components Before You Touch Them

Section 3 starts with design and function. The feed bar, rotation unit, pipe clamp, tie-down beam, mounting frame, and rear anchor legs are all detailed individually. The rotary table (section 3.3), wireline winch (3.4), power unit with starter cabinet and display (3.5), control panel with regulators and gauges (3.6), and water pump (3.7) are all covered. The hydraulic system description uses component-level diagrams. If you’re cross-referencing a part number or trying to understand how the selector valves interact, this is where you go. For fundamental transmission theory, you might also check the Manual Transmission article on Wikipedia or the Manual Transmission primer for gear drive basics. But for this rig, everything you need is between the covers of this Sandvik manual.

What languages is this manual in?

Spanish. The original file is Spanish-language.

Does the manual include wiring diagrams?

Yes—the technical description chapter covers the control panel and power unit electrical systems with schematics, but the exact page numbers for wiring are not listed in the TOC. The hydraulic circuit is fully detailed starting on page 52. For electrical troubleshooting, the control panel section (3.6) includes regulator adjustments and gauge readings. If you need a complete wire-by-wire diagram, you may want to consult Sandvik directly, but for most service work the diagrams in this manual are sufficient.

You want the original Sandvik procedure on your bench, not a copy that misplaces a torque spec. Access the Factory Manual from AutoRepairManuals and keep the 00855-R1 running without downtime.
