Jims’ Piston Jet Test Stand No. 772 allows engine builders to test the piston jets inside Twin Cam engine cases. The unit operates on both compressed air, and air over oil. When operating with air only, verification of proper flow through the piston jet can be witnessed. In the air-over-oil mode, mechanics can not only check for proper operation, but also see the oil spray pattern emanating from the jet. By adjusting the unit’s air regulator, they’re able to determine at what pressure the piston jet turns on and off. The tool also lets them clear assembly lube from the jet’s narrow oil passage. The Piston Jet Test Stand retails for $199 and is backed by a lifetime warranty.
