Kubota V 3307 T Diesel Engine Servicing & Governor Systems

The powertrain section provides deep diagnostic and repair coverage for the Kubota V 3307 T water-cooled, 4-cylinder turbocharged diesel engine rated at 55.4 kW (75 HP) at 2200 rpm. The text outlines the architectural characteristics of the dual crankcase design, linerless cylinder construction, semi-floating valve cover with vibration dampening seals, and the Center Direct Injection System (E-CDIS) featuring four valves per cylinder and vertically centered two-stage injection nozzles. Technicians are provided with complete maintenance procedures, including valve lash adjustment (intake and exhaust clearances specified at 0.15 ± 0.02 mm cold), injection nozzle pressure testing (Phase 1 opening at 186 bar, Phase 2 opening at 225 bar, and seat leak tightness testing at 166 bar), along with timing verification and injection pump service.

Special focus is placed on the cooling circuit’s flow-control thermostat engineered with an integrated bypass recess to eliminate temperature overshooting and water temperature hunting during variable paving loads. The manual details bench-testing the thermostat in an agitated water bath (stroke initiation at 74.5°C to 78.5°C, reaching full stroke of ~8 mm at 90°C), radiator fin cleaning, and anti-freeze formulation (50% ethylene glycol). In the fuel delivery system, the mechanical multi-function governor is broken down across all operational phases: cold starting spring enrichment, idle stabilization (900 ± 100 rpm), high idle regulation (2300 ± 50 rpm), peak torque control, and engine shut-down solenoid (Y58) dual-coil testing (pick-up winding at ~0.38 Ω and holding winding at ~16 Ω). A comprehensive engine troubleshooting table details causes and corrective actions for hard starting, irregular running, excessive exhaust smoke, low oil pressure, and overheating.

ESX Electronic Control Unit, CAN-Bus Architecture & Metrology

Modern road finishers rely heavily on digital network integration. This Bomag BF 300 P service manual details the electronic control architecture centered around the 68-pole ESX micro-controller module (MC). Technicians learn the exact separation between chassis battery ground (terminal 31) and sensitive analog sensor ground (AGND), Pulse Width Modulation (PWM) duty cycles for proportional solenoid valves, and the implementation of dither frequencies to prevent valve spool stick-slip friction. Clear wiring loom overviews detail engine harnesses, preheating circuits, hydraulic valve manifolds, operator station looms, and screed control consoles.

Crucial diagnostic methodology is outlined for the 68-pole ESX controller, including precise test protocols using dummy load lamps (12V/21W) and high-impedance multimeters to verify voltage drop limits (maximum allowable drop ≤ 0.5V) across power supply pins (Pin 28 ignition feed, Pin 54 emergency stop enable, Pin 55 ground, and output bank Pins 56 through 60). Component servicing sections guide mechanics through the repair and testing of the three-phase charging generator, electronic voltage regulator, planetary reduction starter motor (pinion wear limits, commutator minimum diameter of 31.4 mm, and brush minimum length of 11.0 mm), Telemecanique switch blocks, inductive proximity switches, and water-tight Deutsch DT/DTM plug pinning and terminal extraction.

Dashboard Input Codes, System Teaching & Calibration Routines

A standout technical feature of this Bomag 008 917 45 service manual is the complete documentation of instrument cluster input codes. Rather than requiring proprietary external dealer scan tools, the paver allows technicians to configure parameters, calibrate actuators, and interrogate faults directly via the operator display buttons:

• Service Mode Activation: Accessing service parameters with code 0001 under engaged parking brake conditions.
• E-Throttle Calibration: Teaching the rotary servo actuator (M39) mechanical stops and electronic stroke positions using codes 5038, 5039 (idle position verification < 500), 5040 (maximum full throttle position), and 5041 (routine termination).
• Load Control System (LCS) Teaching: Calibrating maximum paving work pressure and stop pressure potentiometers using codes 3006, 3007, and 3008 in conjunction with hydraulic gauge verification.
• Fault Log Management: Accessing logged fault codes (code 0700), viewing error occurrences paired with recorded operating hours (code 0705), and clearing the ESX memory log (code 0710).
• System Configuration & Overrides: Enabling limp-home travel via screed relief push buttons (codes 1100 and 1121), resetting electronic control units to factory baselines (code 7010 with machine-specific profiles 7860/7861), activating/deactivating front-wheel drive assistance (codes 1101/1102), and bypassing a defective brake pedal switch (code 1104).
• Engine Speed Adaptation: Harmonizing software version v0.27 with generator V-belt pulley ratios on early serial machines using code 5046.

Closed-Loop Hydrostatic Drive & Material Feed Hydraulics

The manual provides rigorous schematics and step-by-step servicing instructions for the machine’s extensive hydraulic systems. The travel circuit is powered by an axial-piston variable displacement Bosch-Rexroth A10VG45 pump (45 cm³/re, delivering up to 152 l/min at 370–390 bar operating pressure with 24–26 bar charge pressure), feeding dual Sauer Danfoss 51D variable-displacement bent-axis motors on the rear axle and SAI BD1 radial piston motors on the front wheels. Technicians are provided with complete instructions for troubleshooting axial piston swashplate mechanisms, checking charge pressure filters, testing the shiftable two-speed Officine Meccaniche spur gear transmission (3.103:1 high / 8.052:1 low), and inspecting Bondioli & Pavesi planetary wheel reduction hubs (11.908:1 ratio).

The working hydraulics are supplied by an open-loop Bosch-Rexroth A10VO28 pump (84 l/min, 145–155 bar) alongside multi-stage Haldex WP09 gear pumps. Detailed sub-sections cover the independent dual-motor scraper belt conveyors (Sauer Danfoss OMS 160 orbital motors running at 60–64 rpm), reversible material distribution augers (OMS 160 motors at 80–84 rpm), and hydraulic cylinders controlling hopper folding wings, auger height elevation, screed lift, and crown profile curving (-3% to +4.5%). Testing protocols provide specific setup procedures for checking scraper belt tension, conveyor chain slack, auger clearances, and hydraulic relief valve pressure thresholds.

S340 Screed Mechanics, Electric Heating & Automated Lubrication

Asphalt mat quality depends entirely on the condition and setup of the screed. This manual details the BOMAG S340 vibrating screed assembly (paving widths from 1.70 m to 3.40 m, expandable to 4.00 m with extensions or down to 0.75 m using reduction shoes). The guide explains drawing arm leveling cylinder geometry, mechanical angle-of-attack preset bolts, eccentric shaft vibrator drives (20–50 Hz driven by Sauer Danfoss SNM2 motors at 2650–2850 rpm), and tamper compaction bars (0–30 Hz driven by SNM2 motors at 1800–2000 rpm).

Complete repair procedures are documented for the 230V/400V three-phase screed electric heating system. Service personnel are guided through removing and installing the heavy 65 kg auxiliary heating generator, setting generator V-belt tension via dual adjusting bolts, troubleshooting the external temperature control console, and replacing high-voltage heating rods inside the main screed base plates, extendable mobile sections, tamper bars, and lateral exit flaps. In addition, Section 17 covers the automated Lincoln central lubrication system, detailing grease reservoir refilling (NLGI class 3 lithium EP grease), electronic cycle timer setup, progressive metering valve block operation, and hydraulic blockage clearance techniques.
