This is a hard-to-find adapter you will need if you have an early-1990s 5- or 6-cylinder turbo diesel engine. It is not easy to make these, but we machine this right here in our shop, and it is designed to work directly with our OM61x compression tester ( see related products below):
Product Details
Here is a picture of the adapter hooked up to our compression tester with a quick disconnect included with the tester. No specific instructions are included for doing a compression test on these later diesel engines. The instructions that come with the compression tester are specific for the older 61X four and five-cylinder engines. General principles of doing the test may apply. Note: We include a factory crush washer and 4 aluminum washers with the fitting. Before you install the fitting in the cylinder head, install the heat shield washer first, then install one aluminum washer. Both washers must be used to guarantee a leak-free seal at the pre-chamber. NOTE: The heat shield washer with last through a complete test. Generally, one aluminum washer will last through a test, but if it becomes too deformed, you will have extras. If you are having a hard time getting a seal on any cylinder, remove all the washers and clean the carbon off the pre-chamber and try again.
