The Kubota D1105 and V1505 are among the most widely used small diesel engines in the world — powering mini excavators, skid steers, generators, and compact construction equipment across the Middle East and beyond. Because they share the same block family, owners often aren’t sure which parts are interchangeable and which aren’t. This guide covers how to identify your engine, the parts you’re most likely to need, and how to make sure what you order is genuine.
Kubota D1105 vs. V1505: what’s the difference?
Both engines share the same basic block architecture, but they’re tuned differently:
- D1105 — naturally aspirated, commonly found in mini excavators, mini skid steers, and small generator sets.
- V1505 — a displacement variant of the same family, often used in slightly higher-output generator and industrial applications.
Because of the shared block, many internal parts (crankshaft metal, thrust washers, gaskets) are shared between the two — but always confirm against your engine’s dataplate before ordering, since running changes between sub-models (the “-E2BG” suffix on Kubota part numbers) can affect fit.
The most commonly needed D1105 / V1505 parts
Genuine Kubota part numbers for this engine family follow a consistent pattern (e.g. 16281-65510), which makes cross-referencing straightforward once you know what you’re looking for. The categories below cover the bulk of what owners replace over the life of the engine.
Scheduled maintenance kits
The fastest way to stay ahead of wear is a maintenance kit matched to your service interval:
- 1,000-hour kit — oil, oil filter, fuel filter, and air filter bundled for a standard service: Kubota MK1-Kub-V1505 Maintenance Kit — 1,000 Hours
- 2,000-hour kit — the extended-interval bundle for major services: Kubota MK1-Kub-V1505 Maintenance Kit — 2,000 Hours
Filtration
Air, oil, and fuel filtration is the highest-turnover part category for this engine — expect to replace these on every service interval:
- Oil filter, part no.
HH160-32093 - Air filter, part no.
TA040-93220 - Fuel filter assembly, part no.
1C011-43013(shared across the wider Kubota range)
Cooling and lubrication system
- Complete cylinder head, part no.
16062-03045 - Thermostat, part no.
19434-73015 - Oil pump rotor assembly, part no.
16241-35070 - Dipstick, part no.
16259-36410
Fuel system and electrical
- Fuel injection nozzle, part no.
16032-53610 - Glow plug, part no.
16281-65510— a common cold-start failure point worth checking first if the engine is hard to start - Oil pressure switch, part no.
15841-39013
Engine internals
- Piston (+0.5mm oversize), part no.
16060-21914 - Crankshaft front metal (0.20mm), part no.
16292-23913 - Exhaust valve, part no.
1G673-13120 - Gear case gasket, part no.
16264-04132

How to identify the right part for your engine
- Find your engine’s dataplate. It’s usually riveted to the block itself and lists the exact model and serial number — this is the only fully reliable way to confirm fit, since equipment manufacturers sometimes fit slightly different sub-variants to the same machine model.
- Match the part number format. Genuine Kubota part numbers follow a
XXXXX-XXXXXstructure. If a listing doesn’t show this format, treat it as a compatibility claim to verify, not a confirmed fit. - When in doubt, ask before ordering. Send us your engine’s serial number and we’ll confirm the correct part before you buy.
Genuine parts vs. aftermarket
Genuine Kubota parts are manufactured to the engine’s original tolerances — this matters most on wear-critical components like piston rings, crankshaft bearings, and cylinder head gaskets, where an aftermarket part even slightly out of spec can shorten engine life or cause a comeback failure. For consumables like filters, a reputable aftermarket brand can be a reasonable cost trade-off; for anything inside the block, genuine is the safer call.
FAQ
What is the difference between the Kubota D1105 and V1505 engines?
They share the same block family, but the D1105 is the naturally aspirated variant common in mini excavators and small generators, while the V1505 is a displacement variant often used in higher-output generator and industrial applications. Many internal parts are shared, but always confirm fit against your engine’s dataplate.
How do I find my Kubota engine’s part number?
Check the dataplate riveted to the engine block — it lists the exact model and serial number. Genuine Kubota part numbers follow a consistent XXXXX-XXXXX format, which you can then cross-reference against a parts catalog.
Where can I buy genuine Kubota D1105 and V1505 parts online?
Ghaddar Machinery Co. stocks genuine Kubota D1105 and V1505 parts across filtration, cooling, fuel system, electrical, and internal engine components, with the same part numbers as OEM documentation.
How often should a Kubota D1105 / V1505 engine be serviced?
Most owners follow a 1,000-hour minor service interval (oil, oil filter, fuel filter, air filter) and a 2,000-hour major service interval — matched maintenance kits are available for both.
Do aftermarket parts fit as well as genuine Kubota parts?
For consumables like filters, quality aftermarket brands are often a reasonable choice. For components inside the block — pistons, crankshaft bearings, cylinder heads — genuine parts are manufactured to tighter original tolerances and are the safer choice for engine longevity.
