Full CNC blue print machining, (bore, deck, hone and line honed).
We blue print bore the Cylinder bores to a true 90 degrees from the crankshaft center line, prior to diamond honing to within .0002 inch for precise piston to cylinder bore clearances.
We will main bore and line hone the crankshaft to precisely align the crankshaft in the engine block.
We bore the block back to the crankshaft center line and hone the block to Ra 13 finish. The piston diameter measured to the nearest .0001 inch matched to cylinder bores.
We will surface the Cylinder block on this 5.9L Cummins Long Block to a finish of RA30 or lower, to meet factory specification in both flatness and smoothness for the block to head sealing surface. This is mandatory for proper sealing of a MLS Gasket.
The CHOATE 5.9L Cummins Full Running Engine is rated for 600 HP and fully balanced. This engine is a must for the working man and perfect for regular heavy hauling.
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.
Building engines the way the OEM factory should have in the first place.
