Review on 🔧 Powerbuilt 640811 Back Tap Thread Repair: Restoring Threads with Ease by David Moreno

I have a Dewalt washer with a Honda engine spark plug hole firmly recessed between the muffler, air cleaner and OHC valve cover. The valve cover is so high in relation to the spark plug angle that it is not possible to use a ratchet wrench to remove or tighten the spark plug. Nice Honda design! I ended up threading the spark plug hole as I didn't notice the problem when I first changed the spark plug. I heard about this tool on YouTube and read reviews on Revain. Mark S.'s review was particularly helpful with his caveats and usage steps. Today I received the tool and got to work. I removed the air filter cover to make room. When I also tried to remove the muffler cover, two screws (one on the top and one on the side) didn't come out. Plan B was to completely remove the muffler from the cylinder block, but I didn't intend to do that so the muffler cap stayed. Thank you Honda! Following the directions on the box and Mark S.'s instructions, I lubricated the tool's threads and slowly expanded the tool's threads by having the tool inserted, removed, inserted, removed, etc. I made 5 passes on the threads until I fully expanded the tool's threads. I never tried to "twist" the tool while it was rethreading the hole. When he felt resistance, I shook the instrument just a little to overcome the resistance. The spark plug hole threads looked pretty good after the fifth time, so as a final step I did one final insertion and removal, starting from the outside of the hole, screwing the tool in, then unscrewing it. This is the opposite of how the trimming tool actually works. The tool threads screwed in and out easily, so it was time for the spark plug. I hand tightened the spark plug a few turns, then used long double-jointed pliers to thread the spark plug in until it was fully seated in the spark plug. Hole. As a final step, I was able to give the spark plug a final tight fit using a ratchet socket wrench. I replaced the air cleaner cover and we were good to go. The engine started on the third pull and ran perfectly. As for the tool, the company could expand on the instructions as I found Mark S.'s guide more helpful. There's no harm in posting a company-developed video on YouTube! I would also suggest that a tool turning knob that turns to expand the threads in the motor is better designed for turning in tight spaces. I had to use regular round nose pliers to turn the handle. Finally, remember to lubricate the threads of the tool each time you insert it into the engine block. and then clean it after removing the tool from the hole. It seemed like a good idea to keep metal shavings out of the cylinder. Nice tool!
