Default Six bolt steering box fittings

Working on another conversion. I have a great non-leaking system i dont want to touch until its time.

Anyone know the fitting sizes of the high pressure input and low pressure return on the six bolt RHD steering box?

High pressure is the new fitting, low pressure is the old line that is partially blocked by the oil cooler in this pic.



the fittings are inverted flare male with oring tip just need to know the thread sizes

Figured it out

NTC8193 high pressure pump to box (lower fitting pictured) – M14 x 1.5

NTC8193 low pressure box to resesvior (upper fitting obscured by oil cooler line) – M16 x 1.5


Thank goodness somebody makes adapters for these things

"Thank goodness somebody makes adapters for these things"

Out of curiosity, where did you find the adapters and what kind of PAS pump are you connecting it to?

Jegs makes the m16x1.5 oring tip to an and lots of others do too because it's the fitting on the back of a metric Saginaw pump

The M14 one is a bit harder to find

I'm doing a super secret electric/hydraulic conversion, no more belt driven pump!

I'll post when it's done

You should have asked on the Cummins Land Rover group. Lots of people there have done that.

I used this one for the return line since most pumps/reservoirs have a nipple fitting for the return.
