[AT] Allis Chalmers ED40 injector pipes

Sun Feb 9 09:47:56 PST 2020

Even with the line connected to the injector you can cause a leak when bending the pipe if you start to make the bend too close to the fitting or put too much stress on the line. It can also hinder removing the fitting if the bend is made too close. Putting too much stress on the pipe can affect the way the end of the pipe interfaces and seals to the injector. Even if the fitting is tightened properly, a slightly off centered pipe can leak between the pipe and the back of the fitting.

The best way is to start the bend about an inch or so from the back of the fitting.  I would suggest clamping something to the pipe just behind the fitting to help keep it straight while you bend the pipe. You could use a standard pipe fitting that has an internal diameter about the same size as the external diameter of the pipe that you want to bend. Cut the standard fitting in half and clamp it around the pipe before starting the bend.

Just an after-thought, You said your friend had tweaked the pipes?
He needs to make sure that where the pipe screws to the injector, 
it is inline, not at an angle. Best way for tweaking is with the pipe 
secured inline to the injector. Could be the problem.
