What are the engine torque specs for a c15 cat engine?

There isn't a single "engine torque spec" for a Cat C15 engine. The torque output varies significantly depending on the specific model and rating of the C15. Caterpillar produced many variations of the C15 over the years, each with different horsepower and torque ratings. These ratings are expressed as a range, usually given in lb-ft (pound-feet) at a specific RPM.

To find the correct torque specifications for *your* C15 engine, you need to:

1. Identify the exact model number of your C15 engine. This information is usually found on a data plate affixed to the engine itself. The model number will include details specifying the horsepower and other characteristics.

2. Consult the official Caterpillar service manual for that specific engine model. This manual will provide the precise torque curves (torque vs. RPM) and any other relevant torque specifications for the engine. You can usually purchase these manuals from Caterpillar dealers or online parts retailers.

Without the specific model number of your C15 engine, it's impossible to give you accurate torque specs. Attempting to use incorrect torque values can lead to serious engine damage.
