730 Piston jet test stand

Ensuring your piston cooling jets are functioning correctly is a critical step before closing up the crankcases. This JIMS piston jet test stand allows you to verify the operation of the jets prior to final assembly. It is an invaluable tool for clearing out assembly lubricants, checking the specific PSI at which the jet activates, and visualizing the spray pattern to ensure optimal cooling. This stand is designed to work with 1999 to 2017 Twin Cam engines as well as 2017 to 2026 Milwaukee-Eight models. By catching a faulty or clogged jet on the bench, you avoid the catastrophic engine failure that can result from overheating pistons on the road or track.
