Overview of our Cylinder Head machining process:

All work is done on our premises and starts with a complete tear-down and thorough inspection of every head entering our shop. After a complete evaluation of all components, its on to our State-of-the-Art thermal cleaning system and magnafluxing. At this point, the head enters the second stage of our high tech machine shop where qualified and certified machinists handle the precision stages of restoration to ensure you of superior workmanship and quality every time. CBN resurfacing is performed to eliminate the possibility of head warpage. Valve seats always recieve a 3 angle valve job on one of our 3 Serdi machines. Each valve is machine dressed at the stem and face, conforming with OEM specs. All springs are tension tested, and worn rocker studs are replaced when necessary. In addition new freeze plugs, pollution plugs, valve keepers and valve seals are installed. The cylinder head is then vacuum tested to ensure proper seating of all valves. Specifications and technical updates are readily available thru our AREA and Prosis data programs. This information is utilized during the remanufacturing process to ensure accuracy at all times. Only after a final inspection are our heads ready to ship.

Example of our engine block machining process:

We start with hot tanking to clean then we test and inspect the block for cracks. Main caps are bolted up (without bearings), measured for diameter size and concentricity, and aligned. Next is align-boring or align-honing (when needed). The center line of crankshaft is established. Next, the block is decked. This is done to create an absolutely flat surface, which is parallel to the centerline of the crankshaft and correct angle relative to the bores, for the head gasket and cylinder head to mount upon. - The decking process may also be a method of adjusting compression ratio or decreasing the squish area. - With the block square, the cylinders can be bored and power honed with a torque plate in place. The hone creates the necessary crosshatch pattern on the cylinder walls through the use of dedicated, application-specific stones. Bore chamfering is performed as well. Additional machining processes may be undertaken depending on the level of performance machining desired. We can do it all here.

Overview of our crankshaft balancing and polishing processes:

Our crankshaft balancing process starts by attaching the crankshaft to our CWT Multi Balance 5000 machine. Weights are added to the crankshaft's journals to offset the weight of the rod and pistons (referred to as bobweight). If the weight added is the correct weight to offset the weight of the rods and pistons, the crankshaft is balanced. If the counterweights are too heavy, material will be removed by drilling or milling the counterweights. If the counterweights are too light, weight will be added to the counterweights. This is done by drilling a hole in the counterweight and filling the hole with "heavy metal" or "mallory". This filler metal is denser and heavier than steel (but not stonger) so the weight of the counterweight will increase as a result.
