Jetnut Problem Solving


To check the Jetnut for leaks

Pump grease into the nut until the pressure pad is sticking out 1/8" equally around nut.

Put nut under an equal amount of pressure and watch for leaks.

IF: grease leaks out around seal area, the seal has either been cut or there is a nick in the groove area.

IF: Grease comes out from the bleed area, tighten bleed screw (do not over tighten. If grease continues to leak, the bleed hole must be drilled with a 29/64" flat bottom drill so that the ball can seat properly. Drill about 1/16" deep, staying clear of the groove area. If 1/16" is not enough to get the indentation out, go just enough to remove indent. If the groove area is hit, the nut will be beyond repair.

IF: Grease leaks around threads of fitting, nut has to be counterbored deeper to tighten fit around threads.

Note: When replacing grease fitting, use teflon tape around threads of fitting.

CAUTION: JERRY TOOLS PART #1800 HIGH PRESSURE LEAK-PROOF FITTING MUST BE USED FOR JETNUT TO WORK PROPERLY. IF ONE IS NOT USED, IT COULD CAUSE A FAILURE IN OPERATIONS. CONSULT FACTORY FOR REPLACEMENT FITTINGS.
