The original threaded portion of the spark plug bore will typically consist of eighteen mm threads to match the spark plug threads. A method for repairing a damaged tapered seat spark plug bore according to, 12. Wrenches, PN 44192 and 44182M different lengths. FIG. This leads to Ford's recommendation of replacement of the cylinder head to repair damaged threads in the spark plug bore. 13. 1, but shows the threads of the spark plug bore repaired in accordance with the invention. The method may also include the additional step of: q) obtaining a guide pilot having an internal bore of a size to closely accept a desired size drill bit therethrough smaller than the drill bit needed to drill a hole for the tap and having a lower portion sized to snugly fit into the upper portion of the spark plug bore; r) positioning the lower portion of the guide pilot with the tap extending therefrom in the upper portion of the spark plug bore to align the guide pilot with respect to the bore; s) obtaining a drill bit of desired smaller size to fit in the internal bore of the guide pilot; t) attaching the drive means to the smaller size drill bit to cause rotation of the smaller size drill bit; u) using the guide pilot and drive means, drilling out the damaged spark plug bore below the guide pilot; and v) removing the guide pilot and drill bit from the bore. 2, a fragmentary vertical section similar to that of FIG. 3-5, an insert length from the bottom of the flange of 0.710 inch has been found to correctly position the bottom of the insert at the bottom of the spark plug bore and top of the cylinder. Commonly used for spark plug blow outs in Ford sert kit spark taper plug seat repair thread It is presently preferred to include the second drill bit and second guide pilot so that the repair may be made using manual socket wrenches or lower power air ratchet wrenches. A thread insert and method to replace the damaged threads and tapered seat in a spark plug bore of an internal combustion engine allows for the continued use of the original factory specified spark plugs where the original threads in the spark plug bore have been damaged by stripping or cross threading. sert triton A kit of tools for repairing a tapered spark plug bore according to, 15. thread pro spark m14 tapered insert plug seat repair non pack kit This is important because drilling and tapping a tapered seat spark plug bore destroys the tapered seat in the bore.

The thread insert allows the spark plug to be positioned in the spark plug bore to extend to substantially the same depth in the cylinder as it would have in the original bore thus eliminating the debilitating effects of over or under reach spark plugs. All rights reserved. The guide pilots are specifically adapted for each type of engine. The threads are either stripped entirely or become cross threaded. m10 tapered undocumented, SPARK PLUG REPAIR This problem is compounded by the modern trend to construct cylinder heads from aluminum, a relatively soft metal, and from the reduction of the number of threads in spark plug bores. 3, FIGS. In adapting the thread insert, the length of the exterior threaded shaft must be such that it does not extend into the cylinder when inserted. p/n 4212H 5, but showing an alternate embodiment of the thread insert with the flanged head having a chamfered bottom; FIG. oemtools The flattened side abuts against the cylinder head such that the guide pilot is properly aligned over the spark plug bore. reamer assemblies 14m rethreads With the thread insert of FIGS. FIG. The flange on the insert ensures that the insert is properly positioned in the spark plug bore and the insert cannot be inserted too far into the cylinder. This leads to two complications. Thus, a thread insert. thread pro spark m14 tapered insert plug seat repair non pack kit The flange also allows for easy insertion of the insert using only the spark plug and a normal spark plug wrench or socket. Tooling is long enough for extended reach and can be used for near surface spark plug holes as well using the shorter wrench. The final size hole for the insert is drilled with an eleven sixteenth inch drill bit and tapped with a three quarter inch NF thread tap to provide three quarter inch NF threads in the cylinder head. FORD F-150, 4.9 liter V8 1993 When the threads are damaged, the tapered seat spark plug may not sit properly in the bore which prevents the air tight seal from forming. To summarize the steps of the method of the invention, the basic method includes the following steps: a) obtaining a thread insert according to claim 1; b) obtaining a guide pilot having an internal bore of a size to closely accept a desired size drill bit therethrough and having a lower portion sized to snugly fit into the upper portion of the spark plug bore to thereby align the guide pilot and internal bore in the spark plug bore; c) positioning the lower portion of the guide pilot in the upper portion of the spark plug bore to align the guide pilot with respect to the bore; d) obtaining a drill bit of desired size to fit in the internal bore of the guide pilot; e) placing the drill bit in the internal bore of the guide pilot; f) attaching a drive means to the drill bit to cause rotation of the drill bit; g) using the guide pilot and the drive means, drilling out the damaged spark plug bore below the guide pilot; h) removing the drill bit and the guide pilot from the bore; i) obtaining a tap of a size for producing threads to mate with threads of the exterior threaded shaft of the thread insert and having a portion to extend through the internal bore of the guide pilot; j) positioning the tap in the guide pilot; k) positioning the lower portion of the guide pilot with the tap extending therefrom in the upper portion of the spark plug bore to align the guide pilot with respect to the bore; l) attaching the drive means to the tap to cause rotation of the tap; m) using the guide pilot and drive means, tapping threads into the drilled out spark plug bore; n) installing a tapered seat spark plug into the thread-insert; o) applying bonding agent to the exterior threads of the thread-insert; and p) installing the thread insert and spark plug as a unit into the new bore using a spark plug wrench. Can repair failed helicoils up to .660 inches O.D. kit The lower portion of the guide pilot has a smaller diameter in order for it to snugly slide into the upper portion of the spark plug bore. FIG. 3; FIG. (24mm Reach). A non-threaded portion in the inner bore is disposed above the threaded portion of the inner bore and the top of the thread insert and includes a taper formed in the insert to mate and seal with the tapered seat of the spark plug. For example, the non-original type plug may have a shorter or longer reach than the original plug. A shorter reach spark plug causes the thread insert's threads to fill with residue allowing the spark plug to easily foul and misfire. inserts includes length note a drill bit of the desired size to fit through the internal bore of the guide pilot and drill a hole to be tapped by the tap.
