Product Information
Full details
The Laser Diesel Compression Test Adaptor (7237) is designed for automotive technicians and DIY mechanics who need to accurately measure diesel engine compression. Its primary benefit is extending the compatibility of existing compression and cylinder leakage test kits to a wider range of diesel engines. A key consideration is that it functions as an adaptor and requires a separate compression test kit to be used.

FAQs
What is the primary purpose of this adaptor?
This adaptor allows you to connect standard diesel compression test kits to specific engines by replacing a glow plug with a port compatible with your test equipment.
Do I need a separate compression test kit to use this adaptor?
Yes, this adaptor is an accessory and requires a separate diesel compression test kit (like Laser Part Nos. 4510 or 5140) or a similar compatible kit to perform compression tests.
Which engines is this adaptor specifically designed for?
It is designed for 1.4L and 1.6L DV4 and DV6 diesel engines found in brands like Citron, Ford, Peugeot, Mini, Suzuki, and Volvo, which use an M8 x 1.0 glow plug thread.
What is the thread size and length of the adaptor?
The adaptor has an M8 x 1.0 thread size and a total length of 115mm. The thread portion measures 50mm from the tip to where the seal should engage.
Can I use this adaptor with any compression test kit?
It is designed for Laser kits 2596, 4510, and 5140, and is also suitable for many other common compression test kits that can connect to the adaptor's output end.
How do I clean and maintain the adaptor?
Clean the adaptor with a dry cloth after use and store it in a dry place. Inspect threads for damage before each use.
What glow plug types is it compatible with?
It is compatible with glow plug types such as NGK YE04 and YE12, provided they have the M8 x 1.0 thread specification.
Troubleshooting
Adaptor does not fit glow plug port
Verify the engine application and ensure the glow plug thread size is M8 x 1.0. This adaptor is not compatible with other thread sizes.
Leaking at the connection point
Ensure the adaptor is securely tightened into the cylinder head and that the compression test hose is properly connected to the adaptor. Check for damaged threads on the adaptor or cylinder head.
Inaccurate compression readings
Confirm the adaptor is fully sealed in the cylinder head and that the compression test kit itself is functioning correctly and calibrated. Ensure no air leaks are present.
