Compression Gauge/Tester for Gasoline Engines

grabcad

IV2017 - This is a Compression Gauge/Tester specifically designed for Gasoline Engines, measuring cylinder pressure to diagnose mechanical issues. The gauge features two scales: an outer ring displaying BAR (Atmosphere) readings from 3 to 20 and an inner ring showing PSI (Pounds per Square Inch) readings from 50 to 300. This gauge boasts a simple yet effective design consisting of a sheet metal body manometer with a fixed hose assembly, making it ideal for small engines like lawnmowers, mopeds, outboard motors, and classic bikes. It can be easily attached to common cylinder heads featuring an M14 x 1.5 mm thread. The sparkplug typically has a 20.8 (13/16") mm drive hex, while the adapter is useful for engines with smaller sparkplugs having an M10 x 1.0 mm thread and a 16 mm (5/8") hex. Download Information: The ZIP file includes Inventor Assembly (IAM) and Part (IPT) files, along with assembly STP files containing part files of the components, all located in a separate folder within the ZIP file.
