BGS 165 | Repair Kit for Spark Plug Threads | M10 x 1.0 | 5 pcs.

I had rebuilt a motor bike engine but discovered towards the end of the project that the previous owner had cross threaded the spark plug in the aluminium cylinder head. I bought this kit to sort out that little problem. The kit comes with inserts of varying lengths to suit the thread length of the spark plug fitted although I did check the full specification of the spark plug before I ordered so I knew I was getting the right kit. The tap that comes with the set is very sturdy and can obviously be used more than once so it’s in my tool box for future use.

I used this for my chainsaw Sthill MS211C as the old thread had been stripped out and would no longet hold the spark plug. It took around 15 minutes, afterwards I flushed the cylinder head out with petrol to be sure there were no pieces of alloy still there. Put in the new spark plug and after a few pulls was back in business.

Great for quick fix if you know what you are doing.

Used on a chainsaw to repair the spark plug hole. Did it in place instead of removing the head. Worked well

Used this kit on a 125cc Pit Bike for spark plug thread repair, removed the head in about 5 minutes, used cutting/drilling oil while using the tool, screwed the sleeve into the freshly threaded hole and inserted my new sparkplug... Reassembled the engine, gave her a kick and she fired up with no faults! Cheaper than a new head and very easy, just make sure you remove the head as metal can go into the bore and cause other, unwanted damage.

So easy to use and good quality repair
