- The YATAFORCE YF-908G1 Compression Tester Kit is a professional-grade diagnostic tool designed to measure cylinder compression pressure in petrol/gasoline engines with precision and ease. Engineered for both automotive professionals and DIY enthusiasts, this 8-piece kit includes everything you need to detect engine issues such as worn piston rings, leaking valves, or blown head gaskets. Featuring a high-accuracy 300 PSI / 21 Bar gauge, multiple spark plug thread adapters (M10, M12, M14, M18), and a durable flexible hose, the YF-908G1 ensures compatibility with a wide range of engine types — from motorcycles and cars to light trucks and small engines. All components come neatly packed in a durable plastic carrying case, making it easy to transport, store, and keep your workspace organized.
Features
:- Dual-Scale Precision Gauge : Large, easy-to-read gauge with measurements in both PSI (up to 300) and Bar (up to 20.6) for versatile use.
- Universal Application : Includes four common spark plug thread adapters (M10, M12, M14, M18), covering a vast majority of petrol engines in cars and motorcycles.
- Quick Pressure Release : Features a side-mounted push-button release valve to quickly clear pressure for immediate retesting.
- Enhanced Durability : The gauge is protected by a rubberized boot to guard against bumps and scratches.
- Improved Sealing : Spark plug adapters are equipped with O-rings for better sealing during the compression test.
- Convenient Connections : Includes a flexible hose extension for hard-to-reach spark plug wells, as well as straight and angled rubber-cone-tipped extensions for quick press-on testing on certain engine types (no threading required).
- Corrosion Resistance : Brass, corrosion-resistant fittings ensure longevity and reliable performance.
- Organized Storage : Comes complete with a sturdy blow-molded case for organized storage and protection of all components.
Applications
:- Engine Diagnostics : Identifying issues like worn piston rings, leaking valves, or head gasket failures.
- Routine Maintenance : Regularly checking engine health to prevent potential problems.
- Vehicle Inspection : Assessing engine condition during pre-purchase evaluations or insurance assessments.
- Educational Use : Teaching automotive students about engine compression testing.
Usage
:Usage Guidance (How to Use) :
- Warm up the engine to operating temperature and turn it off.
- Remove the spark plug from the cylinder you want to test.
- Screw in the appropriate adapter from the kit into the spark plug hole.
- Attach the compression gauge to the adapter via the quick-connect hose.
- Crank the engine a few times (4–6 revolutions) using the ignition key.
- Read the pressure on the gauge and compare it to the engine's normal range.
- Repeat for each cylinder to identify inconsistencies.
Maintenance Guidance :
- Clean fittings and adapters after each use with a soft cloth.
- Store the kit in its case to prevent damage or loss of parts.
- Avoid over-tightening adapters to preserve thread quality.
- Keep the gauge dry and avoid dropping it to ensure calibration is maintained.
- Periodically check the hose and seals for wear or cracks and replace as needed.
