Enter your JCB engine part number (320/xxxxx) to identify the engine type and find a replacement
Every JCB 444 engine carries a data plate containing the full engine identification number. This number tells you the displacement, aspiration type, part number, country of manufacture, serial number, and year of build.
Engine data labels A are located on the cylinder block at position C and rocker cover D (if fitted). The data label includes important engine information and the JCB engine identification number E.
The last three parts of the engine identification number (country, serial number, and year) are also stamped directly on the cylinder block at position B.
A typical JCB engine identification number is made up as follows:
When contacting us for a replacement engine or quote, providing your full engine identification number (all six parts) allows us to identify the exact specification straight away.
Every JCB 444 engine has a part number (320/xxxxx) which identifies that specific engine build, and a build specification code (e.g. 9802/2910) which identifies the base engine configuration — the combination of displacement, aspiration, fuel system, and emission tier.
The build spec code tells you what type of engine it is, even if the individual part number isn't listed here. If you can find this code on your engine data plate, it narrows down the replacement immediately:
For Tier 4i and T4 Final engines, the two-letter prefix on your engine identification number is essential for identifying the exact power output and configuration. See our machine cross-reference tables for help matching by machine model.
Use our JCB 444 Engine Cross-Reference Tables to find the correct engine by machine type, model, and emission tier.

Understanding JCB engine part numbers, build spec codes and replacement options
JCB engine part numbers starting with 320/ are the factory assembly number for a complete engine.
Each number identifies a specific engine configuration including the emission tier, aspiration type, power output and voltage. For example, 320/40000 is a Tier 2 naturally aspirated 55kW 12V engine.
The trailing code on a JCB engine number is the build specification. It identifies the engine family and configuration: 9802/2910 is Tier 2 naturally aspirated, 9802/2940 is Tier 2 turbo, 9812/2300 and 9812/2400 are Tier 3 turbo electronic, 9812/2350 and 9812/2450 are Tier 3 mechanical, 9822/0500 is Tier 4i EcoMax, and 9822/0920 is Tier 4 Final." }
The engine part number is stamped on the data plate fixed to the engine block. It follows the format 320/xxxxx.
You may also find it on your original purchase documentation, JCB dealer invoice, or by providing your machine serial number to a JCB parts dealer.
Yes. Timik Engines stocks new JCB 444 engines across all emission tiers including Tier 2 naturally aspirated and turbo, Tier 3 mechanical and electronic, Tier 4i EcoMax, and Tier 4 Final. Engines are available to purchase online with immediate pricing and stock availability.
Both are Tier 3 JCB 444 engines but with different fuel systems. The 9812/2300 uses electronic fuel injection (turbo electronic), typically at 68kW or 74kW.
The 9812/2350 uses mechanical fuel injection (TCA mechanical), typically at 74kW or 93kW. The correct replacement depends on your machine's original specification." }
