John Deere PowerTech 4.5L and 6.8L Non-Certified and Tier 1 Certified OEM Diesel Engines Operator's Manual (OMRG25204)

Engines covered

OMRG25204 (Issue 02Nov06) is for PowerTech 4.5 L (4045) and 6.8 L (6068) OEM engines with mechanically controlled fuel systems, built from 1996 on. It covers non-certified engines and Tier 1 certified engines (EPA Tier 1 in the US, Stage 1 in the EU), from all three plants:

• Saran, France (CD): for example CD4045DF120, CD4045TF150 to TF258, CD4045HF150 to HF252, CD6068TF120 to TF258, CD6068HF150 to HF258

• Dubuque, Iowa (T0): T04045DF120 to DF153, T04045TF120 to TF251, T06068TF150, T06068HF250 and others

The full model list and the serial number rules (pre-2005 and post-2005) are on the first pages. This manual is for engines supplied to outside equipment makers, such as generators, pumps and industrial units. Engines in John Deere tractors and machines are covered by the machine operator's manual.
