The specific design considerations for the 3406B include:<\/p>\n<ul>\n<li>Reliability<\/li>\n<li>Serviceability<\/li>\n<li>Long Life before Overhaul is Needed<\/li>\n<li>Low Overhaul costs<\/li>\n<li>Application Flexibility<\/li>\n<li>Fuel Economy<\/li>\n<li>Oil Control<\/li>\n<li>Performance<\/li>\n<\/ul>\n<p>Caterpillar has always emphasized strength and quality, and continues to do so with the 3406B. The 3406B is a heavy-duty, in line, 6- cylinder, diesel engine. The engine has a 5.4 inch bore, 6.5 inch stroke and a displacement of 893 cu. in.<\/p>\n<p>The major engine components will now be discussed in detail.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2080\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/cylinder-block-3406b.jpg\" alt=\"cylinder block 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Cylinder Block<\/h1>\n<p>One of the major components in a diesel engine that must exhibit maximum strength is the cylinder block. To provide maximum strength, the block is precision cast using a combination of alloys.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2063\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/cylinder-head-3406b.jpg\" alt=\"cylinder head 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Cylinder Head<\/h1>\n<p>The cylinder head is designed to have excellent structural strength and ridgidity. The cylinder head has passed rigorous, deep thermal cycle shock testing for assured durability. This results in a cylinder head with significant resistance to cracking.<\/p>\n<p>The steel or aluminum spacer plate that is used between the cylinder head and the block eliminates the need for deep counterbores in the cylinder block. Deep counterbores decrease the structural integrity of the block and are prone to cracking.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2064\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/crankshaft-3406b.jpg\" alt=\"crankshaft 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>3406B Crankshaft<\/h1>\n<p>The crankshaft is a carbon steel forging that is total hardened. Many other diesel engine manufacturers induction harden their crankshafts only at the journals and fillets. This process can leave a stress riser at the boundary between the hardened and unhardened areas. The patented Caterpillar total-hardening process hardens the entire surface of the crankshaft, creating a longer wearing and stronger crankshaft. With the entire surface of the crankshaft hardened, the possibility of cracking is reduced.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2065\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/crankshaft-3406c.jpg\" alt=\"crankshaft 3406c\" width=\"237\" height=\"159\" \/><\/p>\n<h1>3406C Crankshaft<\/h1>\n<p>With the introduction of the 3406C, the size of the rod bearing has been significantly increased (projected area by 19%). The wider bearing spreads the load over a greater surface area, dramatically decreasing the bearing load while increasing the bearing life. This photo shows a former rod bearing on the new crankshaft to demonstrate the increase in bearing area. Additionally, this change increases the oil film thickness by 50% and gives the 3406C the largest rod bearing capacity in its class, eliminating mid-life bearing roll-ins.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2066\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/connecting-rod-3406b.jpg\" alt=\"connecting rod 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Connecting Rods<\/h1>\n<p>The forged boron steel connecting rod is hardened and shot peened for stress relief. The tapered-end design provides additional pin to bore contact area during the power stroke. This results in extra strength and durability of the piston and rod assembly.<\/p>\n<p>New with the 3406C is a larger, stronger connecting rod with a much larger rod bearing. In fact, the wider 3406C rod bearing has the greatest load carrying capacity of any heavy duty engine in its class. By spreading the firing loads over a larger surface area, load carrying capacity, bearing reliability, and service life are all dramatically increased for all ratings.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2067\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/piston-3406b.jpg\" alt=\"piston 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Pistons<\/h1>\n<p>Pistons are critical to the design, life, and overall performance of an engine. The Caterpillar 3406B Engine&#8217;s three-ring piston is an aluminum alloy casting with a cast-in nickel iron band for the compression rings. The nickel iron band provides improved groove strength and resists wear.<\/p>\n<p>The three-ring piston design provides excellent compression and oil control while reducing friction and heat buildup. This results in extended piston, ring and liner life and reduces maintenance cost at overhaul time.<\/p>\n<p>The piston rings are nodular iron for strength and durability. The oil and intermediate rings are chrome coated, while the top ring is plasma coated. Both coatings provide excellent wear and scuff- resistant properties.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2068\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/liner-3406b.jpg\" alt=\"liner 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Cylinder Liners<\/h1>\n<p>Cylinder liners are made of a cast molybdenum alloy iron for an extra margin of hardness. The internal surface of each liner is induction hardened, then ground in a cross-hatched pattern to aid in oil control. O-rings are used to seal the liner to block coolant cavity. A liner band is used to seal the top of the liner. Because the engine is rigid, these seals remain seated and provide excellent liner sealing.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2069\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/valve-3406b.jpg\" alt=\"valve 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Valves<\/h1>\n<p>Exhaust and intake valves in the 3406B Engine are extremely wear resistant for long life. Three materials are used in the exhaust valves. The stems are made of a hardened stainless steel. A special alloy is used for the heads to provide high temperature strength. The seating faces of the valve are made of Stellite for high temperature wear resistance. Intake valve heads and stems are made from stainless steel and are hardened for resistance to wear.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2070\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/valve-seat-insert-3406b.jpg\" alt=\"valve seat insert 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Valve Seat Inserts<\/h1>\n<p>When the valve seats become worn or damaged, valve seat inserts are replaceable. Intake inserts are a stainless steel alloy and the exhaust inserts are a nickel base alloy.<\/p>\n<p>Each valve has a rotator which moves the valve face 3\u00b0 relative to the valve seat during one complete cycle of the engine. This assures uniform wear for longer valve life and helps prevent burned valves.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2071\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/camshaft-3406b.jpg\" alt=\"camshaft 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Camshaft<\/h1>\n<p>The camshaft is made of a special alloy steel that is drop forged and hardened for reliability and durability.

The BrakeSaver develops a retarding capability of 360 hp and maintains normal engine temperatures on long downhill grades. The hydraulic operation of the BrakeSaver provides smooth, gradual engagement, reducing the possibility of skids or jackknives.<\/p>\n<p>By relieving the service brakes of the severe wear caused by downhill braking, the BrakeSaver extends brake lining, drum, and tire life.<\/p>\n<p>This reduces user maintenance costs.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2073\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/fuel-pump-3406b.jpg\" alt=\"fuel pump 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Fuel System<\/h1>\n<p>The 3406B utilizes a direct injection, scroll type, high pressure fuel system.

Earlier 3406B Engines used a spring\/hydraulic system. As engine speed increases, timing is advanced hydraulically using engine oil. As engine speed decreases, a large spring pushes the timing mechanism toward the retarded position. The spring\/hydraulic system has a timing advance capability of 9 degrees.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-2077\" src=\"https:\/\/penambang.com\/wp-content\/uploads\/2014\/12\/hysraulic-timing-advance-3406b.jpg\" alt=\"hysraulic timing advance 3406b\" width=\"237\" height=\"159\" \/><\/p>\n<h1>Hydraulic Timing Advance<\/h1>\n<p>A double hydraulic automatic timing advance was introduced on the 3406B Engines, serial number 4MG3600 and up.
