Kubota V3800 Common Rail Fuel Injector Kit 1J500-53076 (Genuine)
Kubota 1J500-53076 Common Rail Fuel Injector Kit
The Kubota 1J500-53076 is a genuine common rail fuel injector kit, listed in the Kubota parts catalog as INJECTOR,KIT, for the 3.8 liter Kubota V3800 common rail engine family (V3800-CR-T, V3800-CR-TE4 and V3800-CR-TIE4). It is the latest number in the 1J500-5305x/5307x supersession chain and the factory injector for Kubota M8560 and M9960 tractors and the SVL90-2 compact track loader. The injector itself is a Denso common rail unit (095000-9690 / 095000-9691), supplied here as the complete genuine Kubota kit.
Application & Fitment
Confirmed applications for part number 1J500-53076:
- Engines: Kubota V3800-CR-T, V3800-CR-TE4, V3800-CR-TIE4 (3.8L common rail, Tier 4 interim)
- Kubota M8560 tractor (M8560HD, M8560HDC, M8560HF, M8560HFC)
- Kubota M9960 tractor
- Kubota SVL90-2 compact track loader
Aftermarket listings also show this injector for the Kubota M4N-071HD12 narrow tractor, and the same Denso injector is sold for Bobcat A770, S750, S770, S850, T750, T770 and T870 loaders (Bobcat 7024332 / 7485369) and for CAT machines built on the Kubota-based C3.8 engine (CAT 389-5232). We have not verified those fitments against Bobcat or CAT factory catalogs, so call us to confirm before ordering for a non-Kubota machine.
Supersession: 1J500-53076 replaces 1J500-53050, 1J500-53051, 1J500-53052, 1J500-53053, 1J500-53054, 1J500-53055, 1J500-53070, 1J500-53072 and 1J500-53074. If your parts diagram shows any of those numbers, this is the current genuine part. Note that it is not the same injector as 1J508-53076, which serves the later V3800-TIE4B/TIE5B engines in SVL95-2s and SVL97-2 loaders.

Frequently Asked Questions
Will 1J500-53076 fit my machine?
If your machine runs the V3800-CR-T, V3800-CR-TE4 or V3800-CR-TIE4 engine, yes: that covers the M8560 series and M9960 tractors and the SVL90-2 track loader, plus anything specced with the earlier 1J500-5305x/5307x numbers it supersedes. The safest check is your engine model and serial number. Call us and we will confirm the exact part before you order.
Why buy a genuine Kubota injector instead of aftermarket?
A common rail injector meters fuel at extremely high pressure, and calibration is everything: hard starts, white smoke, rough idle and lost power are what a marginal injector looks like. The genuine Kubota kit is the same Denso injector the engine was built with, supplied new in the complete factory kit and backed by an authorized Kubota dealer, so there is no gamble on gray-market or counterfeit stock.
How do I order this injector kit?
It is on the shelf here in Woodland — order it on this page and it ships free ground in the lower 48. If you would rather have fitment confirmed first, call 530-668-0818 or send us a note through our contact page with your engine model and serial number and we will check it against your build before anything leaves.
Why source your Kubota parts from Valley Fuel Injection
As an authorized Kubota dealer and diesel fuel injection specialists, Valley Fuel Injection & Turbo supplies genuine Kubota engines and fuel system components, and we service and rebuild the very common rail systems these parts run in. Diesel is all we do, and we have done it from Woodland, California since 1993.
Pricing & availability: $1,195.00 per kit, in stock in Woodland and ready to ship — ships free ground in the lower 48. Genuine Kubota injectors are sold outright, so there is no core charge and nothing to send back. Buying all four for a V3800, or want the part confirmed against your engine serial first? Call 530-668-0818 or contact us.
Why do I see this common rail injector cheaper online?
Short answer: it is usually not the same part — and common rail does not forgive “close enough.” Read why ↓
Search any OE number and eBay, Amazon and a dozen storefronts will show it well under dealer cost, sold by outfits with no name, no address and no phone number. We lose business to those listings every week — and we see a lot of them come back through our shop. Here is what is actually different.
- The part number proves nothing on its own. Counterfeit injectors and pumps are stamped with the same OE numbers as the real thing, in housings cast to look identical. The number in the listing title tells you what the seller claims it is, not what came off an OE line.
- “Remanufactured” is not a regulated word. A genuine reman unit is stripped to bare components, has its wear parts replaced — nozzle, plunger and barrel, solenoid, seals — and is then run on a calibration bench until it meets the original flow and response spec. A cheap one is very often cleaned, resealed, painted and shipped. Both get called remanufactured.
- No full teardown, so no idea what is worn. A proper rebuild means the unit comes apart completely and every part gets inspected and measured against spec — not just the ones that are obviously bad. Skip the teardown and you are reusing worn internals inside a freshly painted housing. It will run on the truck. It will not last.
- No factory-spec bench load testing. A unit is not finished until it has been run under load on a test bench and made its numbers across the range, not just at one easy point. That bench time is most of what you are paying for. Sellers working on price cut it first, because nobody can see it in a photo.
- The warranty has to be honored by someone. Everything we remanufacture in house carries a one-year warranty, with 30 days on electrical components. Parts we supply as an authorized dealer carry the manufacturer’s own warranty. Either way you call us, a real shop in California, and we sort it out. A marketplace warranty usually means shipping the part overseas at your own cost and hoping for a reply.
- No core program. We credit your rebuildable core back in full. Discount sellers generally will not take one, so the gap narrows the moment you account for the core you are now stuck holding.
- Common rail has no tolerance for “close enough.” These injectors meter fuel in fractions of a millisecond at pressures north of 20,000 psi, across multiple events per stroke. A nozzle or control valve that is merely near spec will not throw a code on the bench at idle — it shows up as a cylinder that runs hot, a balance rate that drifts, fuel in the oil, or a rail pressure fault six months out. And the labor to go back in is the same as it was the first time.
We are an authorized dealer and a working fuel-injection shop — we have been rebuilding and testing this hardware in Woodland since 1993, and the people who answer the phone are the people who run the benches. Not sure this is the right part for your engine? Call us with your serial number before you order and we will confirm it. Send your rebuildable core back and the core charge is refunded. And if a price somewhere else looks too good, call 530-668-0818 and we will tell you straight whether it is a deal or a problem.
