Operating instructions for 0001-000-3472 cylinder leakage tester
This document provides operating instructions for the EGUIP Model 2509 Cylinder Leakage Tester Kit. It details the necessary steps to prepare an engine for testing, such as removing spark plugs and positioning the piston at top dead center on the compression stroke.
The manual explains how to connect the tester to an adequate air source and interpret gauge readings to determine cylinder leakage percentages. It also lists methods for diagnosing specific issues based on where escaping air is detected.
When using a 100 psi source, the regulated gauge should be adjusted to read 90 psi.
Air escaping from the crankcase breather indicates defective rings or worn cylinder walls.
A difference of 5 psi between cylinders is considered satisfactory.
