Im sat here with a std T2, thread gauges and a vernier trying to work out wtf the thread size is for the oil feed fitting.
It is measuring- 11.3mm core, 13mm OD with a pitch of 1.25mm.
so you'd think M13x1.25........however that thread doesn't exist, no one makes a fitting that size, or a die that size to cut a thread. Speaking to my guy in the toolroom i'd be akward to screw cut that size of thread as well.
1/2" UNC almost fits, but i think the pitch is wrong (works out at 1.27mm)
1/4" BSP also almost screws in, but not quite.
Im told that T2's only come with 2 size oil feed holes, but the T2 i have on the phase 1 uses a M11x1mm fitting, i also have a knackered T2 with a fitting that is too big for the one on my phase1, but too small for this T2 in front of me.
****ty Europeans and their weird automotive thread sizes, wtf is wrong with good old BSP?
Can anyone help/know what size thread i need?
