Frequently Asked Questions
What is included with leakdown tester 35-1377?
The dual-gauge tester includes a 25-inch hose and stepped adapter; one gauge reads 0-100 PSI and the second reads 0-100 percent leakage.
How is an engine positioned for a cylinder leakdown test?
Place the cylinder at top dead center on its compression stroke with both valves closed, lock the crankshaft safely and apply regulated shop air according to the tester and engine procedures.
How can leakdown air help locate an engine fault?
Air heard at the intake points toward an intake-valve leak, at the exhaust toward an exhaust-valve leak and at the crankcase toward ring or cylinder leakage. Confirm results against the engine's service limits.
