Jims Tools 730 Piston Jet Tester for Twin Cam & Milwaukee-Eight Engines

The Jims Tools 730 Piston Jet Tester is an essential diagnostic tool for Harley-Davidson engine builders and technicians working on Twin Cam and Milwaukee-Eight engines. This specialized test stand allows you to verify the proper operation of piston cooling jets before final engine assembly, ensuring optimal engine performance and longevity.

Key Features:

• Tests piston cooling jets for Twin Cam and Milwaukee-Eight engines
• Helps determine if piston jets are stuck open or stuck closed
• Verifies the PSI at which jets open and begin spraying oil
• Allows visualization of spray pattern before engine cases are sealed
• Assists in clearing jets of assembly lubes during engine building
• Prevents issues from leaking or clogged cooling jets
• Made in the USA

Piston cooling jets spray oil onto the underside of pistons to reduce operating temperatures by approximately 50°F. Leaking jets can cause excessive oil flow into the crankcase and high sump levels, while clogged jets can reduce or eliminate critical piston and cylinder lubrication. This tester helps diagnose and prevent these issues before they become costly engine problems. Note: Piston jet nozzle not included with tester.
