This electronic unit injector assembly is supplied for CAT C15, C18, C27 and C32 engines, covering four displacements from fifteen to thirty-two litres on a single figure. The neighbouring figure in the same block is not a variant but the pair partner, and the two are fitted as a set rather than mixed. Both new and remanufactured releases are offered, each with its own trade figure.
| Product Name | Electronic unit injector assembly |
|---|---|
| Figure | 253-0615, written without the dash as 2530615 |
| Remanufactured | 10R-3264 |
| Pair Partner | 253-0616, with its own rebuilt figure 10R-3265 |
| Neighbouring Figures | 253-0617, 253-0618, 244-7715, 235-1401, 235-1402 |
| Engines | C15, C18, C27 and C32 — four displacements on one figure |
| Machines | Large excavators in the three hundred tonne class, and off-highway trucks |
| Quantity Per Engine | One per cylinder, six on the smallest of the four |
| Condition Offered | New, and rebuilt with tested solenoid and nozzle |
| Supplied With | Clamp, copper washer and O-ring seals as a set |
| Packing | Tip protected, solenoid capped, one pocket per injector |
| Four Sizes, One Figure | A fifteen litre and a thirty-two litre engine accept the same body, so displacement alone tells a buyer nothing about which injector is fitted. |
|---|---|
| Pair, Not Variant | The figure one digit higher is the matching half of a set released for the same build, and mixing the two in one engine leaves half the cylinders working to a different curve. |
| Rebuilt Is A Different Figure | The rebuilt release is quoted under a prefix rather than a suffix, so a buyer scanning for a tail will never find it. |
| Two Descriptions, One Item | The trade calls this injector by two different system names, and the two cannot both be right, so the engine plate is the only reliable guide. |
| High Hour Neighbours | Older figures from the same machine family still circulate and are frequently offered as equivalents, which works only when the build year matches. |
| Machine Spread | The same injector appears in mining excavators, in off-highway haul trucks and in the largest wheel loaders, so a single listing serves several trades. |
| Caution — Price Signals Condition | Listings at a fraction of the going rate are usually a nozzle, a solenoid or an empty body, and the title alone will not say which. |
| Caution — Washer Thickness | The copper washer sets the installed height, and a doubled or reused washer changes the spray position enough to score a piston crown. |
| Caution — Socket And Torque | The clamp bolt has a specified torque and the body is easily distorted by a rattle gun, after which the injector will not seal. |
| Caution — Coding After Fitting | The trim code on each injector has to be entered before the engine is run, otherwise fuelling stays on the previous calibration. |
| Related Components | Clamp and bolt, copper washer, O-ring seals, harness, valve cover gasket, fuel transfer pump. |
Yes, which is why the machine plate matters more than the displacement.
No, they are released as a pair for a reason.
By its prefix figure, not by a suffix on the original.
Because it is a component of the injector rather than the assembly.
Yes, or the engine keeps fuelling to the old calibration.
The copper washers, the clamp bolts and the harness.
