ATP Total Quality Approach to a Remanufactured Engine
 Steps to Remanufacture Blocks:
  • First, the blocks are completely disassembled and cleaned with all plugs removed, 
  • Then washed BEFORE and AFTER machining for a minimum of 3 times, 
  • Blocks are then crack tested, 
  • Any broken bolts are removed and any damaged threads are repaired and cleaned,
  • Torque plates are used when required by O.E.M, 
  • All cylinder walls are platue brushed for quick piston ring seating,
  • The main bearing saddles are align-bored, 
  • and Lastly, new freeze plugs and galley plugs are installed.

Our Steps to Remanufacture Crankshafts and Connecting Rods:

  • First, both crankshafts and connecting rods are cleaned and shot blasted,
  • Then, they are checked for straigtness and twist,
  • They are then reground and micro-polished to a 10 micro finish,
  • Micro Sleeves are then installed on most crankshafts, for a new seal surface,
  • and Lastly, connecting rods are precision honed and balanced in sets to within 7 grams.

Our Steps to Remanufacture Cylinder Heads:

  • First, We completely disassemble the cylinder heads to ensure a thorough cleaning of all coolant and fuel passageways,
  • Then, the cylinder heads are oven cleaned and thoroughly blasted to remove all carbon and oil deposits,
  • They are then magnafluxed to detect any cracks,
  • Then, they are accurately resurfaced to ensure a proper gasket seal,
  • The valve guides are then replaced or repaired using bronzeguide liners,
  • The valve seats are then machine cut to a triple angle (all three angles are cut simultaneously),
  • Hardened seats are then installed (when applicable),
  • The valves are then machined at stem and face,
  • New rocker studs are installed when needed,
  • The springs are then cleaned, tested and installed with shims to maintain proper tension,
  • Lastly, they are vacuum tested to ensure proper valve seating.

Our Steps to Remanufacture Camshafts:

  • First, the camshafts are reground to O.E.M standards,
  • They are then parkerized for break-in and durability,
  • Lastly, all new camshaft bearings are installed in the block.

The Final Step: Engine Assembly:

  • First, the crankshaft is installed with all new bearings and rear seal,
  • The thrust clearance is measured at installation,
  • Then, the piston and rod assembly is installed with "Prolong" assembly lube,
  • The piston to bore clearance is measured three seperate times on the engine,
  • The main and rod bolts are then torqued to manufacturer specifications and Loc-Tite is applied,
  • New or reconditioned camshafts are then installed with new timing components,
  • Cylinder heads are then installed with new gaskets, head bolts sealed (if applicable) and torqued to manufacturer specifications,
  • Head bolts are marked to verify that they have been torqued,
  • New lifters and push rods are then installed with clean and inspected rocker arms and fulcrums, New rocker arm adjusting nuts complete the valve train,
  • Every engine cooling system is air pressure tested for leaks,
  • Engine assemblies are spun on SIMS engine tester.
  • Lastly, the compression, oil pressure and oil flow are monitored.
