Tech Tip #120: How to Order a Kubota 2003 Engine Overhaul Kit: Five Easy Questions

Tips on how to order a Kubota 2003 engine overhaul kit: five easy questions
This Tech Tip is one of a series that we publish on maintaining industrial and marine engines and power takeoffs. This Tech Tip focuses on how to order an engine overhaul kit for your Kubota 2003 engine. While this Tech Tip focuses on the Kubota 2003 diesel engine, if you are working on a Kubota 2203 engine you should check out Tech Tip  #110: How to Order an Engine Kit for a Kubota 2203 Diesel Engine.
Rebuilding Kubota engines can be difficult. The parts are expensive, Kubota uses funny terminology, and their prices are high. Very high. Moreover, you can’t buy a complete engine overhaul parts kit for a Kubota like you can with almost every other industrial engine. In other words, you can’t call your friendly Kubota engine dealer and place an order for an engine kit. Rather you have to order it piece by expensive piece. And it gets worse. Because you have to order it part by part, you have to understand how Kubota uses the English language. For example, what we would call a rod bearing, they call a “metal, crank pin”. All in all the only people who make any money overhauling a Kubota diesel seem to be the telephone company and Kubota.
But Foley can help! We can save you both time and money. We stock complete engine overhaul parts kits for the Kubota 2003. Our kits include pistons and piston rings up to .020 oversize, rings, rod, main bearings thrust washers, a complete Workshop Manual, engine paint, Tech Tips, a Dr Diesel coffee cup for when you read the manual etc. etc. Not only are the kits complete, the rings come loaded on the pistons so you don’t run the chance of breaking any rings. If you have a cylinder that is worn beyond .020 we now even offer a repair sleeve that allows you to sleeve your Kubota 2003 back to standard.
We make ordering an overhaul parts kit for a Kubota 2003 easy. You can do it in one phone call and without having to learn Japanese. Here is what we need to know if you want to order a kit for your 2003 Kubota.
How to Order a Kubota 2003 Engine Kit
1) What is the Engine Model Number?
The model number will be read similar to “V2003T-E” and end in either an E or an M. We need to get this right because it will affect the main and rod bearings, pistons and gaskets that we send you.
2) What is the Engine Serial Number?
If you don’t have this, please advise if the engine is in a 2004 or later machine.
3) Is it a Generator Engine?
Please let us know if your engine runs a constant 1800 RPM in a generator or is a variable speed engine.
4) Fuel Injectors?
Please confirm that your fuel injectors screw in as on a Perkins or push in as on a John Deere. If your injectors push in, please re-check your serial number.
5) Location of the Fuel Shut-Off Solenoid?
Please advise if the fuel shut off solenoid is mounted near the fuel injection pump or on the front cover.
There you have it. To overhaul a Kubota 2003 diesel, just make one call to us and give us the answers to these five easy questions. With us you don’t have to order 46 different part numbers, learn new terminology and pay $1000 more than you should for a parts kit. Just call us toll free at 800 233 6539 and we can get an overhaul kit right out to you. We also stock new oil pumps for your Kubota and strongly recommend that you install one as part of your overhaul. Our pricing is good on the pumps too. We have new pumps for roughly $150. Given this low price, why reuse a worn, dirty old pump?

Is the engine a fixed speed, 1800-RPM generator engine?
3) Location of the fuel shut down solenoid
Is the fuel shut down solenoid located on the front timing gear cover or is it on the injection pump?

Tech Tip #79: Kubota 2203 Identification: A Field Guide

How to properly identify your Kubota diesel engine
The Kubota 2203 Diesel has gone through several iterations including Tier and Tier Two emission compliant versions and this Tech Tip is a Field Guide for easy identification.
Kubota 2203 M Series vs. BG and E Series
2203 M Series The fuel shut off solenoid is mounted in the front timing gear cover
2203 BG and E Series The fuel shut off solenoid is located behind the fuel injection pump on block
Kubota 2203 Direct vs. Indirect Injection Engines
All of the above 2203 series diesels were shipped as either direct or indirect fuel injection engines.
2203 series Kubota direct injection diesels have a push-in pencil style fuel injectors similar to a John Deere diesel
2203 series Kubota indirect injection diesels have shorter, thicker, screw in injectors similar to a Perkins diesel
O3 Series
03 Series Kubota Diesels were Tier One Emission compliant before January, 2001 using a Kubota diesel serial number prior to 4A000. They use small crankshaft bearings
03 Series Kubota Diesels were Tier Two Emission compliant effective January, 2001 and after. They use Kubota diesel serial number 4A000 and up. They used larger crankshaft bearings.

Tech Tip #77: Identifying your Kubota Four Cylinder Diesel

How to correctly identify your Kubota engine
Dealers tell us that we broke new ground with our new engine overhaul parts kits program for Kubota diesels. Prior to our Kubota engine overhaul parts kits, people who wanted to overhaul their Kubota were stuck. They had to buy their parts one at a time from their local Kubota dealer because the factory doesn’t offer Kubota rebuild kits. Not only wasn’t this a whole lot of fun, but buying parts one part at a time from a bored lawn and garden parts guy was expensive. Our Dr Diesel felt your pain. He says that buying parts one at a time for a Kubota engine overhaul is like buying a keg of beer one bottle of Budweiser at a time. Because of this we came up with this new program of Kubota engine kits. This little Tech Tip helps you identify your Kubota engine so you can order an engine parts kit from us in one toll free phone call.
A little background is always good. Kubota four cylinder diesels have been shipped to the US in a variety of configurations and variations. These variations include indirect and direct injection fuel systems, Tier 1, Tier 2 and Tier 3 emissions compliant engines, etc. As a result the internal engine parts will vary. We will ask you three things when you call to order an engine kit.

Engine model and code. A Kubota diesel’s base engine model is found on the metal tag on the side of the head. Usually it is the first line on this tag. For a four cylinder Kubota diesel, it will probably be model 1702, 1902, or 2203. The engine code is equally important. This is a ten digit number separated in the middle by a dash located on the same engine ID plate. This Kubota engine code is located on the third line of the engine tag. This engine code functions much like the Cummins CPL or a Perkins diesel build list. It tells us which pistons, rings and liners as well as other internal parts you need. It is all important.
If the engine ID plate is missing from the Kubota head, the engine serial number is scribed into the block on these four cylinder Kubota diesels just behind where the injection pump is bolted on. We can use this to then get the engine code number.
We would also like to know what the Kubota diesel engine is used in. If for example, the Kubota you are overhauling is out of a skid steer loader but aren’t sure if you has a V1702 or a V1902 Kubota engine, we could pin it down with the make of the skid steer such as a Skat Trak or a Clark Bobcat. For example, very few Kubota 1902s were used in anything but Skat Trak skid steers.

Foley Engines takes tech support seriously. We also believe strongly in the concept that we belong to a community of engine professionals that depends upon on the free exchange of ideas for its continued success. We are active in our professional association, the AERA, and our Dr Diesel is currently a Director of the AERA.  All in all, we and want to help engine rebuilders get good tech information, sometimes in cases where engine manufacturers are not very forthcoming. As with all of our Tech Tips, we welcome your comments and suggestions.
