Buyer guide
- Cat's cited 3406C industrial engine uses a hydra-mechanical governor. Confirm whether the machine needs this control type before using 3406C data for a listing labeled only 3406.
- The same 3406C reference lists an SAE No. 1 flywheel and housing plus a rear-sump oil pan. Compare these physical interfaces with the existing installation.
- Cat rates this non-certified industrial 3406C reference from 280 to 347 kW at 1,800–2,100 rpm. Verify the offered engine's plate and local emissions requirements.
Buying questions
Which governor does Cat list for its industrial 3406C reference?
A hydra-mechanical governor. Confirm the actual 3406 generation and control arrangement on the offered engine.
What drive and oil-pan layout does the cited 3406C use?
Cat lists an SAE No. 1 flywheel and housing and a rear-sump pan for that industrial configuration. Verify both on the supplied build.
