Hi all

Ive been trying to get a replacement or even something made up for the return line on the 990 Implematic, No wreckers in NZ have one and even the hydraulic shops have nothing small enough in the same thread as an aftermarket. Has anyone else had this problem and come up with a fix for it ?

The tank fitting is smaller than the other end which seems to be more common ?

Cheers in advance
Luke

Have you tried to ask a brake garage?

The thread in the nut is 1/8 BSP and the tank end is secured with a banjo bolt.
All the bits are available for making up a new pipe if you shop around.

The Selectamatic pipe will not fit, the connections are wrong.
Do you require a banjo bolt?

The fuel tank port must be smaller than that as the 1/8 male doesnt fit in , not even close but 1/8 female on the rail does fit fine.

The pipe is connected to the tank with an 8mm banjo bolt and sealed with two copper washers.
Any other connection will not work because there is no seat for a conical type fitment ( olive )
1/8 BSP is not interchangeable with 8mm banjo bolt thread.

Perfect! Thanks heaps db2d , fitted it all up and good to go, strange thing though, The hydraulics seem to be controlled with the clutch in relation to the pto . The hydraulics are only able to be raised or lowered when the clutch pedal is released, soon as I press it, the hydraulics stop wrking and the pto disengages as it should. I cant remember if this was like it before it was split in half for a clutch as it was a long time ago? Ive only got the repair manual, waiting on an operations one to come. Have I knocked a lever somewhere?

Cheers Luke

If your tractor is a Non-Livedrive the clutch is working as it should. If it is a Livedrive the set-up adjustments probably need setting. A Livedrive clutch has two stages of pedal movement - the first stage disengages the transmission only and the second stage disengages the transmission, PTO and hydraulic system.

Livedrive serial number VAD 4/47A. Non-Livedrive VAD 4/47B
