This Kubota V3307-DI-T-E3B-WLTC1 Parts Catalog (OEM #93304-00110) documents a single diesel engine: the turbocharged, EGR-equipped V3307-DI-T-E3B-WLTC1 fitted to the 45ZV-2. Of its 64 pages, 50 hold exploded-view parts lists covering every major assembly: crankcase, oil pan, cylinder head, piston and crankshaft, the fuel injection pump unit with governor and solenoid, nozzle holders, starter, dynamo, water pump, EGR valve and cooler, turbocharger, and the upper and lower gasket kits. Every diagram ties component names to OEM part numbers with full interchangeability callouts, so you confirm the right piece before ordering. The 12V/80A dynamo assembly splits into individual rotor, stator, rectifier, and bracket parts, each carrying its own REF number. With your machine idle and the dealer quoting list price, look up the exact OEM number yourself. Bookmarked by assembly and keyword-searchable: find the part, check the cross-reference, place the order.

Kubota V3307-DI-T-E3B-WLTC1 Common Problems This Manual Covers
Kubota V3307-DI-T-E3B-WLTC1 engine will not crank or only cranks weakly in cold weather p. 36
Inspect the starter assembly exploded view on page 36 and note the part number for the 12V 3.0KW starter motor. Match the flange nuts and spring washers shown so the mounting hardware suits your serial number.
Manual Section: 554000 スタータEngine requires starting fluid to run due to suspected injection pump component failure or poor fuel delivery p. 23
Review the injection pump components list on page 23 and locate the 0.35mm injection pump shim by part number. Cross-reference the joint bolts, flange nuts, and air bleeder screws in the index to build a complete replacement order.
Manual Section: 521000 燃料噴射ポンプLow power with heavy black smoke traced to restricted exhaust or EGR cooler leaks p. 46
Check the EGR cooler exploded diagram on page 46. Locate the correct part numbers for the base components and cooler gaskets. Find the replacement 50-65 hose clamps and flange bolts required to reassemble the exhaust system properly before returning the machine to service.
Manual Section: 572400 ＥＧＲクーラOil pressure lamp remains on after start requiring immediate oil cooler component identification p. 49
Examine the oil cooler parts breakdown on page 49 for the cartridge and joints. The 73.5X3.1 O-ring seals this assembly, so grab its part number, and confirm the water pipe joint components match your engine configuration.
Manual Section: 582000 オイルクーラSevere engine misfire and heavy crankcase blowby requiring identification of oversize piston replacement parts p. 16
Pull the engine parts diagram on page 16. Locate the +0.50mm oversize piston kit and matching piston ring assembly part numbers. Identify the correct connecting rod assembly, piston pins, and crankpin metals required for a complete lower end rebuild on this machine.
Manual Section: 511000 ピストン・クランク軸Frequently Asked Questions
How do I find the correct starter motor part number for the Kubota V3307-DI-T-E3B-WLTC1?
The starter assembly exploded view on page 36 lists the 12V 3.0KW starter motor with its part number. Match the flange nuts and spring washers shown in the diagram to confirm the correct hardware for your serial number.
Which injection pump shim thickness does the V3307-DI-T-E3B-WLTC1 use?
The injection pump components list on page 23 specifies a 0.35mm shim (part number 1G790-5216-2). Cross-reference the joint bolts, flange nuts, and air bleeder screws in the index to build a complete replacement order.
What parts are needed to address EGR cooler leaks causing black smoke on the V3307-DI-T-E3B-WLTC1?
Check the EGR cooler exploded diagram on page 46. Locate the part numbers for the base components and cooler gaskets, and find the replacement 50-65 hose clamps. Ordering gaskets and clamps together avoids a second disassembly if the base seal is also weeping.
What are the replacement specifications for battery?
As an illustrated parts list, this manual gives no replacement specs for the battery itself. It does list the dynamo (alternator) as part number 1G398-6401-0 rated 12V 80A, which indicates the electrical system's voltage and alternator output.
