The Bobcat E88 Compact Excavator Service Manual S/N B62N11001 & Above 2025 is written for the excavator mechanic. It supplies servicing and adjustment procedures for the machine and its component systems. Operating instructions, starting, and daily checks remain in the Operation & Maintenance Manual; this book is the shop-level companion.

Who This Manual Fits

Coverage is limited to the E88 compact excavator beginning at serial B62N11001. The power unit is the 2.4 L Bobcat Engine, V2, Stage 5 — a four-cylinder, direct-injected, turbocharged and intercooled diesel with 2,392 L (146.0 in³) displacement, closed crankcase ventilation, and glow-plug starting. Gross output is listed at 48,5 kW (65.0 hp) ISO 14396 and 48,7 kW (65.4 hp) SAE J1995, with rated power 48,5 kW (65.0 hp) SAE J1349. Torque figures include 248,0 N·m (182.9 lb-ft) ISO 14396 / rated and 249,2 N·m (183.8 lb-ft) SAE J1995. Low idle is 1200 ± 25 rpm and high idle is 2100 ± 25 rpm.

Machine identification plates, engine serial location (side of the engine below the alternator, next to the oil fill tube), front and rear component callouts, and delivery-report requirements are all in the foreword so parts orders and service inquiries can be tied to the correct unit.

Hydraulic Work You Can Carry Out

Section 30 starts with a symbol glossary and separate troubleshooting trees for the hydraulic circuit, cylinder circuit, slew circuit, and travel circuit. Each work-group cylinder — boom (standard and articulated-boom machines), arm, boom swing, bucket, blade, clamp, and articulated boom — has leak-down testing, pin-off and hose isolation steps, parts identification, disassembly, and assembly. Relief hardware is treated as its own group: main relief description, port-relief pressure test and adjust, cross-port relief with gauge-port specifications, and the pressure-reducing valve used for pilot supply.

The hydraulic control valve chapter covers description, R&I, parts ID, and section-by-section disassembly. Pump work is worksheet-driven: no-load high-idle rpm is recorded first, then test fittings go on the pump and the P port of the pilot manifold. Procedures set minimum displacement, pump margin, load-sense relief, and torque-limiter flow at low and high pressure. System relief is specified at 295 bar (4279 psi). Pump capacity is 149 L/min (39.4 U.S. gpm); auxiliary flow is 95 L/min (25.1 U.S. gpm), with secondary auxiliary 62 L/min (16.4 U.S. gpm) at the base/female coupler and 41 L/min (10.8 U.S. gpm) at the rod/male coupler. Joystick control pressure is 30 bar (435 psi). Port-relief figures are given for arm, boom, bucket (340 bar / 4931 psi), blade base and offset (380 bar / 5511 psi), 4th auxiliary and auxiliary relief (210 bar / 3045 psi), and articulated-boom ports (270 bar / 3916 psi).

Cylinder bore / rod / stroke tables and cycle times (bucket curl 3.1 s, boom raise 4.9 s, blade lower 2.3 s, and the remaining functions) let you confirm a rebuilt actuator or a pump that is back on the worksheet numbers.

Undercarriage, Tracks, and Upperstructure

Track service is split by type. Rubber-track procedures cover tension check and adjust, lifting the frame onto jackstands, and driving the track off and on. Steel and segmented tracks add master-pin and cotter-pin steps. Component R&I includes the idler and related rollers. A dedicated inspection chapter explains how rubber tracks crack, gouge, or de-track when stones pack the frame or the machine works across side slopes. Blade R&I is in the same section. Travel-motor fluid is SAE 80W-90 API GL-4 or GL-5; final-drive capacity is 1,3 L (1.37 qt) each.

Upperstructure work reaches the swing motor gearbox (1,5 L / 1.6 qt), bucket teeth and pins, X-Change wear inspection called out in the post-repair checklist, and both standard and German-system hydraulic quick couplers, including a hydraulic schematic for the German coupler. Cover, toolbox, center-cover, grille, fuel-transfer-pump, and louver R&I support access for the engine and hydraulic jobs above.

Electrical Analysis and Cab Systems

Electrical coverage includes charging-system voltage tests (low- and high-voltage paths at the alternator), starter diagnostics, battery jump-start rules, fuse and relay maps (Engine ECU 25 A, Heat 40 A, and related circuits), and the 12 volt, 90 amp alternator / 1000 CCA battery / 2.0 kW starter specification set. Display and control chapters document the engine-speed dial, auto idle, Eco Mode (maximum speed dropping from 2450 rpm to about 2080 rpm when Eco Mode is on), wait-to-start and DPF icons, and the Remote Start Tool kit 7217666 with excavator harness 6689747 and computer harness 6689746.

The Engine Control Unit description explains injection quantity, timing, and pressure control from sensor inputs. Camshaft and crankshaft position-sensor R&I, auto-idle pressure-switch service, travel-motion-alarm checks, and multi-sheet wiring schematics labeled E88 S/N B62N11001 & Above (example sheets include Radio/Wiper/Fuel and HVAC) give a path from a stored code to a connector.

Cab service in the safety section plus section 80 covers the ROPS / TOPS / FOPS structure (ISO 3471 / ISO 12117-2 / ISO 10262 Level I), door and window latches including the front window raise-and-latch sequence, emergency exits through the front or right window, windshield washer reservoir, HVAC louvers, recirculation and fresh-air filters, R-134a charge of 1,18 kg (2.6 lb), compressor belt, reclaim/charge with a recovery unit, and Auto HVAC ATM flash codes.

2.4 L V2 Stage 5 Engine and DPF

Engine service is a full teardown path, not a filter-only chapter. After the description and sensor map, the book lists metric and component torque values, a cause-coded troubleshooting chart (will not start, no power, low oil pressure, knocking, running rough, and related faults), then engine R&I with designated lift brackets. Shop tests include compression through the glow-plug adapter (MEL10630 kit plus 7313843 adapter), in-line injector signal, and oil pressure at the turbocharger inlet (minimum 10 psi within four seconds of start; high-idle gauge pressure 300 kPa / 3,0 bar / 44.0 psi).

The DPF chapter defines passive, automatic, forced, and forced-parked regeneration, icon behavior, and the gates for a forced cycle (no active DPF codes, coolant above 40°C / 104°F, soot load 75–120 percent, more than 25 percent fuel). Fuel-system R&I runs from filter housing and lift pump through the transfer / high-pressure pump, fuel recirculation valve, rail, injectors, and the requirement to write each injector ID code into the ECU with the Bobcat V2 Engine Analyzer, then run ten minutes at full throttle for learning.

Bottom-end and top-end work includes piston and rod R&I, cylinder-block bore 89.990–90.010 mm (3.5429–3.5437 in), crankshaft and connecting-rod inspection with component-class tables, camshaft and bushing, gear-case timing and backlash, turbocharger oil feed and drain, flywheel and ring gear (flywheel bolts 67,8 N·m / 50 ft-lb plus 45°), and EGR. Head-bolt tightening is initial 39 N·m (29 ft-lb) plus 90° + 90° + 90°. Coolant choices are purple 53% propylene glycol / 47% water or red 50% ethylene glycol / 50% water; the thermostat is fully open at 97°C (207°F); radiator cap is 110 kPa (1,1 bar / 16 psi).

Capacities, Performance, and Shop Data

Section 90 collects the numbers used throughout the procedures. Operating weight for a cab with HVAC, short arm, rubber tracks, counterweight, standard bucket, and 75 kg (165 lb) operator is 8994 kg (19827 lb), with adders for steel tracks, add-on counterweight, long arm, and articulated boom. Travel speed is 2,5 / 4,4 km/h (1.6 / 2.7 mph). Digging forces per ISO 6015 are listed for long arm, short arm, articulated boom retracted and extended, and bucket. Fuel tank 116 L (30.6 U.S. gal), hydraulic reservoir 21,4 L (5.65 U.S. gal), hydraulic system at sight-glass center 81,4 L (21.5 U.S. gal), cooling system 10,4 L (2.75 U.S. gal), engine oil and filter 9,8 L (10.35 qt). Track width is 450 mm (17.7 in) for rubber, steel, and segmented options; crawler width is 2200 mm (86.6 in); slew speed is 9,0 rpm. Lift-capacity charts cover long arm, standard arm, add-on counterweight combinations, and articulated boom. Service-tool lists name the Remote Start kit, hydraulic tester MEL1744, engine analyzer, compression and seal tools, and HVAC service equipment used in the procedures.

Get the Manual and Get Back on the Job

With the Bobcat E88 Compact Excavator Service Manual S/N B62N11001 & Above 2025 on the bench you can lift and block the machine correctly, follow the service schedule, test and rebuild work-group cylinders, set pump margin and torque-limiter flow, service rubber or steel tracks, trace a charging or display fault, regenerate or replace the DPF, measure a cylinder bore, code new injectors, charge the R-134a system, and check every torque and capacity against the published tables. Using the printed pressures, idle speeds, and tightening sequences avoids guesswork that damages a Stage 5 fuel system, a load-sensing pump, or a ROPS cab. After payment you receive the PDF immediately — no shipping wait — so you can open it on a shop computer, tablet, or phone and print the pages you need for the current repair.
