Machining Processes Include:

• Full CNC blue print machining, (bore, deck, hone and line honed)
• The Cylinder bores are blue print bored to a true 90 degrees over the crankshaft center line
• Diamond honed to within .0002 inch for precise piston to cylinder bore clearance
• Bored and line hone the crank bore housing to precisely align the crankshaft in the engine block.
• Torque Plate Honed
• The piston diameter measured to the nearest .0001 inch matched to cylinder bores.
• The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface.
• This is mandatory for proper sealing of a MLS Gasket.

Cylinder Heads- While there aren't as many issues with the bottom end of the Cummins, there are really BIG problems in the head department. Valve seats fallout contacting the piston and cause catastrophic failure.

We machine oversize valve seats within creased press fit area to remedy this issue. Stamped gallery plugs in the heads blow out causing a mixture of oil and coolant, destroying the bearings. We thread the head and insert threaded plugs to make sure this issue never rears its ugly head.

Plus: Freeze plugs in the block blow out leaving you at best stranded on the side of the road, at worst, with a severely overheated engine in need of Remanufacturing. Every new Choate Cummins engine comes standard with billet freeze plugs that are blow out proof using a tie bar bolting them into the side of the block.

Assembled by Our Professional Team in house This CHOATE engine is fully balanced, and is the perfect engine for spirited daily driving, consumer level towing and everyday life.

Upgrades over the Model C include but are not limited to:

• Torque Plate Honing
• Full Engine Balancing
• Harmonic Balancer
• Head Studs
• Upgraded Warranty

This 5.9L Full Running Dodge Cummins Diesel Engine Includes just about everything bolted to the engine to make for a quick painless install. This includes but is not limited to the following: a factory original turbo, oil pump, water pump, engine sensors, fuel pump and injectors:

Long Block work is as follows:

Full CNC blueprint machining, (bore, deck, hone, and line honed)

The Cylinder bores are blue print bored to a true 90 degrees from the crankshaft center line, prior to being diamond honed to within .0002 inch for precise piston to cylinder bore clearances.

We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block.

We bore the block back to the crankshaft center line and hone the block to RA13 finish. The piston diameter measured to the nearest .0001 inch matched to cylinder bores.

The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface. This is mandatory for proper sealing of a MLS Gasket.
