AW4 Fill Tube


NAXJA Forum User
What's the size of the bolt holding the trans fill tube to the bell housing? The XJ I bought recently doesn't have one. 5/16 coarse? Also does the vent tube for the transfer case bolt there too? I'm use to the AX15 so unsure on this one.
The parts diagram didn't show it, but most likely metric. The diagram calls the tube "tube, oil indicator", btw.

Yeah I grabbed a M8 x 1.25 to try. I'll see if that works. The bellhousing to block bolts are 3/8 but that's into good ol' American cast iron. Whereas this bolt is into the Japanese AW4.
The AW4 is all metric.
