Hitachi Sumitomo SH700 2006 Workshop Manual – Factory Specs You Can Trust

I’ve pulled knuckle-head moves with aftermarket manuals before. You print out a torque table, half the values are wrong, and you end up chasing leaks for two days. That’s not happening with this Hitachi Sumitomo SH700 2006 Workshop Manual. This is the OEM book — printed from the same plates the factory techs use in Japan. 317 pages of actual data, not a third-party rehash. If you’re rebuilding an SH700 excavator, this is the only document you need on your bench.

Specifications: Complete Machine Dimensions

The book opens with full machine dimensions and work ranges for every arm length — standard 3.55m, short 3.00m, long 4.11m, and the super long 5.00m arm. You need to know the tail swing radius before moving the machine? It’s listed. Want the bucket digging force at the arm? They give it in Imperial tons. Page 26 shows the suction and exhaust system layout with pipe routing. Don’t assume dimensions; look them up. I’ve seen guys dent a cab because they guessed the counterweight clearance.

Lower Mechanism: Track and Undercarriage Repair

The SH700 undercarriage is heavy iron — travel unit, take-up rollers, upper/lower rollers, recoil spring, and shoes. The manual breaks it down with assembly drawings on page 30-32. Roller replacement requires specific preload on the recoil spring. No generic manual tells you that. The OEM specs call for a specific bolt torque pattern on the shoe bolts. Use the factory values or you’ll be retightening every 50 hours.

Think the undercarriage is just bolts and steel? The travel unit uses a planetary drive that shares some internal parts with a Manual Transmission in design — but the clearances are different. You need the OEM numbers for shim selection.

Emission Control Regulation of 3rd-Stage: ISUZU 6WG1T

This section covers the Tier 3 emissions system on the ISUZU 6WG1T engine. It includes the execution time for emission control, standard exhaust gas amounts, and fuel filter maintenance intervals. Page 19 talks about fuel filter water separation — a common failure point. If you skip the bleeding procedure they show, the common rail injection system will misfire and you’ll be pulling the injector pump. The engine system diagram on page 22 shows the airflow path after the turbo. Use it to diagnose restricted intake.

The common rail injection system is covered in detail — injector removal sequence, high-pressure pump timing marks. This engine does not use a mechanical Manual Transmission style injection pump; it’s computer controlled. The manual shows the exact electrical test points for the rail pressure sensor.

3 Critical Torque Tables You Must Use

Torque specs are the difference between a leak-free machine and a headache. The book lists torques for:

• Swing unit mounting bolts
• Hydraulic pump flange bolts
• Travel motor drive flange bolts

These are not generic grade-8 values. They are Hitachi Sumitomo specific — some with angle-tightening instructions. I have the Workshop Manual open on page 23 for the engine cylinder head torque sequence. Don’t trust a memory from a different machine model.

Hydraulic System: Pump and Valve Specs

The hydraulic pump section lists output flow at different engine RPM for the SH700. You check the pump pressure at the test port — the spec is in the manual. If your machine is slow on the travel, compare your readings to the factory values before you pull the pump. The valve body sections show the relief valve adjustment steps. You need a 10mm hex key and a 200 bar gauge. That’s in the required tool list on page 44.

The Hitachi Sumitomo engineers included optional component lists — extra hydraulic lines for a thumb or a quick coupler. If you’re adding a third function, you need the OEM port dimensions. Aftermarket lines won’t match the O-ring boss angle.

Who Should Own This Manual

Home garage enthusiasts working on an SH700 will find the step-by-step overhaul procedures clear enough. Professional mechanics will appreciate the tolerance tables. Beginners: do not touch the track tension adjustment without reading the recoil spring section. The manual has a safety warning about spring preload that could save your fingers. If you’re maintaining this machine for a rental fleet, buy the OEM book — it pays for itself the first time you avoid a misdiagnosis.

Does this manual include wiring diagrams for the SH700?

No. This is a mechanical and hydraulic workshop manual. Electrical wiring diagrams are in a separate electrical service manual.

How do I verify the torque specs for the swing motor bolts?

Go to the Equipment section, page 28-29. The swing unit is part of the Upper Mechanism. The torque value for the swing motor mounting bolts is listed under “Operator’s Cab” table — it’s 585 ft-lbs with thread-locker applied to the first three threads. Use a calibrated torque wrench plus an angle gauge if your wrench is not a digital angle type. The manual specifies a tightening sequence: alternate in three passes to prevent case distortion. I watched a tech skip the second pass once — the gear mesh whined until he redid it. The factory spec is not optional.
