Basic specs are open to everyone and include images, displacement, dimensions and weight, essential bolt tightening torques, the characteristics of the engine like its power and torque.
Essential bolt tightening torques are the main bearing cap bolt torque, the connecting rod cap bolt torque and the cylinder head bolt torques.
MTU 4000 main bearing caps Lateral socket-head screws : Step 1 = 80 Nm Step 2 = 280 Nm +20 Nm
MTU 4000 Con Rod step 1 = Tighten 25 Nm step 2 = Pretightening torque 240 Nm +20 Nm step 3 = Additional angle of rotation 90° +10° step 4 = Checking torque 450 Nm
Cyl Head step 1 = Tighten 25 Nm step 2 = Pretightening torque 180 Nm +10 Nm step 3 = Additional angle of rotation 180° +10° step 4 = Checking torque 400 Nm
Frequent abbreviations you will encounter in MTU manuals and literature: KGS - Kraftgegenseite - (Engine free end) KS - Kraftseite - (Engine driving end) OT - Oberer Totpunkt - (Top Dead Center)
MTU 4000 bore and stroke bore = 165 mm stroke = 190 mm MTU 4000 Displacement - Displacement per cylinder = 4.06 liter 8V4000 = 32.48 liter 12V4000 = 48.72 liter 16V4000 = 64.96 liter 20V4000 = 81.20 liter
MTU 4000 Cylinder designations MTU use the DIN ISO 1204 specs in which Left is defined as A and Right is defined as B. Sides are viewed from the driving end, or 'KS' in the ISO specs; this means as viewed from the flywheel. Numbering cylinders begins from the flywheel end starting with A1 = Left 1; and B1 = Right 1. MTU 4000 firing orders: Rotation (facing rear end) - Counterclockwise 8V = A1-B4-A4-A2-B3-A3-B2-B1 12V = A1-B2-A5-B4-A3-B1-A6-B5-A2-B3-A4-B6 16 V = A1-A7-B4-B6-A4-B8-A2-A8- B3-B5-A3-A5-B2-A6-B1-B7 20 V = A1-B5-A8-B7-A5-B2-A7-B10-A2-B3- A10-B6-A3-B4-A6-B9-A4-B1-A9-B8
MTU 4000 Dimensions - approx guide - varies with every application, and can include accessories like marine coolers and so on: length 8 cyl length = 2340 mm 12 cyl length = 3220 mm 16 cyl length = 3690 mm width - all 8 cyl height = 1380 mm 12 cyl height = 1620 mm 16 cyl height = 1620 mm height 8 cyl height = 1990 mm 12 cyl height = 1835 mm 16 cyl height = 1890 mm
MTU 4000 Weights - approx guide - varies with every application: weight 8 cyl = 4630 kg 12 cyl = 5134 kg 16 cyl = 6541 kg 20 cyl = 7640 kg
