Review on Paisley Industries Compression Cylinder Diagnostic by Jesse Bailey

The caliber seemed accurate compared to another similar one. I have previously tested compression on a Yanmar tractor, several models of which, including Yanmar's smaller John Deere series, have similarly designed fuel injectors. Can be used in two ways, one uses part #4, a 1/8" NPT coupler along with 1/4" NPT-M to 1/8" NPT-F (not included included) and is screwed into the nozzle from the side. Another option is to unscrew the top of the nozzle and screw in a #7 12mm x 1.25"F - 18mm x 1.5m after cutting about 1/4" off the bottom of this fitting. I angle the edge outward at a 45 degree angle while sanding on a 1" x 30" belt sander. Take special care to remove all shavings. I then used #6 12mm x 1.25m - 7/16" x 20m with a flat washer to keep it from sinking along with thick teflon tape. Further up I used a #15 7/16 " x 20m - 7/16" x 20F used, which is a 90 degree adjustment. I attached a #5 7/16" coupler to it. The second method uses a larger hole (about 1/4". ) than the first (less than 1/8". In any case, you must remove all internal parts of the injector and use only the body. The instructions for this set are partly Chinese-oriented, but clear. It would be nice if the fittings were labeled I did this with a fine tipped permanent marker so I didn't have to take out the threadmeter every time.Also instead of having 2(once) and 3(twice) the same fittings different sizes can be used for greater vehicle coverage. Around the nozzles too remove, I soaked the edges with penetrating oil overnight, and then i loosened the 2 top nuts and moved the nozzle to the side. Wrench by pulling up with pliers.
