stripped fuel connection to aluminum fuel pump

Ron Corkum · Aug 18, 2009

I wonder if anyone out there has had a problem such as mine and was able to come up with a good solution!
My john Deere 510 diesel has a banjo type connection on the fuel line from the tank to the fuel pump.It was leaking so I tried to tighten it a bit more and the thread chewed out of the aluminum casting.Not my day!
Can helicore threads be used here,or some other method to create a new thread?
PS my first thought,I bought a new fuel pump but with the loader on and the fuel pump bolts being very inexcessible,I canniot get the old one off! It seems like there is not room to get a socket on the bolt head being very close to the casting! Help! Thanks in advance!

THread Sert, or other brand of solid insert with a locktite application will be easiest, and least likely to leak. Drill square, put a no lint gag down the passage to pull metal out, and it will be fine. JimN

HELLO rON,
Helicoil will work with no problem. The only think is that thr tool kit, that you thread the insert size for is used only for that size, and it comes as a kit. In the future you will only have to by the inserts. Good choice and works well for pressure and torque applications.
Guido.
