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 diesels. 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 waster and a copper washer with the fitting. When you install the fitting in the cylinder head install the heat shield washer first then install the copper washer. Both washers must be used to guarantee a leak free seal at the prechamber.
