MIKEY II - EXHAUST MANIFOLD REPAIR

  1. Mount the ProPlate™ to the cylinder head using the included ProFast PPF008375 or PPF008500 precision fasteners according to the included cylinder head schematic. Torque to a minimum of 20 FT-LBS.

  2. Insert the ProBushing™ and corresponding ProDrill™ machine grade tooling bit into an air-powered angled style drill and use the drill depth gauge machined into the ProPlate™ to set the proper depth of the bit and mark the bit if necessary. Apply one drop of the ProLube™ PPL001 drilling & tapping cutting fluid. AVOID PENETRATING OIL/SPRAY OR OTHER LUBRICANTS.

  3. Insert the mounted ProDrill™ into the included ProBushing™ mounted in the ProPlate™ first by slowly and manually turning the chuck until the ProDrill™ slips into the bushing and contacts the surface of the damaged stud. This will ensure the cutting edge is not damaged. Important step to avoid drill bit breakage. While applying light pressure, activate your drill both on and off five times (ten times if utilizing an air ratchet) in one second intervals. This is the MOST CRITICAL step of this repair as it facilitates precise alignment by creating a “seat” for the tooling bit to stay on center and not follow the angular broken surface of the stud. Moreover, this step allows the surface of the stud to conform to the cutting edge of the bit distributing the load evenly across the entire cutting edge of the bit providing for cutting extremely hard surfaces and extending cutting tool life.

  4. After this initial start, drill continuously running your drill at the proper RPM (see below) and while the bit is turning, extract the bit in and out of the damaged stud while maintaining it in the bushing to “clean” or “excavate” cutting debris from the stud. Repeat this step progressively exerting more pressure until your drill reaches the maximum depth.

  5. After Step 4, run drill continuously at proper RPM (see cutting speeds below). While the bit is turning, slightly extract the bit in and out of the damaged stud to “clean” or “excavate” cutting debris from the stud (commonly referred to as peck drilling). Repeat this step progressively, exerting more pressure until drill reaches the marked depth.

  6. Inserting ProTractor (PPT125): Remove the ProPlate™ and place the optional ProCutter (PPC007A) in drill. Insert the protruding portion of the arbor into drilled hole. Toggle the drill on and off five times to remove the burr and clean the tapped hole. With ProTractor (PPT125), place a mark approximately .” from the end and lightly hammer the ProTractor (PPT125) into the remnant, to the .” depth line. DO NOT INSERT THE PROTRACTOR ANY FURTHER THAN 1/4" depth line. Place the included slip-nut over the ProTractor™ and slide it up against the cylinder head. While holding the opposite end of the ProTractor™ and using a high-quality calibrated torque wrench, slowly and carefully apply torque, first in the clockwise direction, and then in the counterclockwise direction to loosen the damaged stud. Repeat this motion several times NOT EXCEEDING 75 IN-LBS OF TORQUE FOR THE PPT125 OR 150 IN-LBS FOR THE PPT188. If the damaged stud fails to release, STOP and remove the ProTractor™ and proceed to the next step

  7. Inserting ProTractor PPT188): using the larger (optional) ProDrill™ and corresponding ProBushing™, repeat steps 3-5 to prepare in using the larger extractor (PPT118).

NOTE: In the unlikely event an extractor fails or breaks, contact technical support at 724-941-0941 for recommendations and procedures. ProKits can also be upgraded to be an “extractorless” repair: Repeating drilling instructions above and chasing threads clean with a machine grade tap.
