Harley Twin-Cam: JIMS Piston Jets Tester


Motorcycle Tools

There is no doubt that the lifeblood of your Harley-Davidson’s Twin Cam engine is its oiling system.

Crucial to oiling yet often overlooked are the piston jets. Located deep inside the Harley-Davidson’s engine cases, it’s hard to verify whether the piston jets are functioning properly…until now.

JIMS new Piston Jet Test Stand (No. 772) allows mtoorcycle engine builders to test these jets for proper operation before installing them. 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 you can not only check for proper operation, but also physically see the oil spray pattern emanating from the jet.

By adjusting the air regulator on the unit, mechanics are able to determine at what pressure the piston jet turns on and off.

An additional benefit of the Piston Jet Test Stand is the ability to clear assembly lube from the jet’s narrow oil passage. Don’t let malfunctioning piston jets cause your Harley-Davidson Twin-Cam’s engine to sump or overheat, test them before you install them.

JIMS Piston Jet Test Stand has an MSRP of $199 and is backed by a lifetime warranty. For more information connect with JIMS on the web at jimsusa.com.
