SPM-HEP-5202 is the electronic unit injector: the grey body with the plunger spring, the white solenoid cap with two terminal pins and the nozzle with its sealing rings. It is used on Caterpillar C18, C27 and C32 engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
It replaces Caterpillar 295-9085 and Caterpillar 10R-8988.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Yes, it is a direct replacement for the Caterpillar 295-9085 with the same fitting.
Often 5,000 to 10,000 hours, but much less on poor or wet fuel. Injectors are usually changed when they fail a test, not by hours.
Black or white smoke, a misfire or knock on one cylinder, hard starting, higher fuel use, or a high return leak or balance rate on test.
Clean the bore and seat of carbon, and keep the nozzle capped until it goes in. Torque the clamp to the engine manual, not by feel.
Not always. If the others pass a return leak or balance test, one can be changed. Where they are all high hours, a full set keeps the cylinders even.
No. It is an aftermarket fuel injector made to replace the Caterpillar 295-9085. It is not made by the original manufacturer; the number only shows what it replaces.
