Product Questions & Answers (2)

Question by: Dale D on Nov 7, 2025, 8:15 AM
got a older tractor that needs a new steering unit, displacement is 7.3 cu in/rev and ports are 3/4-16 straight thread O-ring. this one gonna match up?
Answer by: Customer Support on Nov 9, 2025, 6:20 AM
For port and displacement specs, yes, that lines up. The unit runs 7.30 cubic inches per revolution and uses 3/4-16 straight thread O-ring ports. Mounting is handled by a 4x .375-16 UNC-2B pattern on the mounting face, with 2x .375-24 UNF-2B on the port face. The mechanical interface is an internal involute spline, 12 tooth, 16/32 DP, 30 degree pressure angle, so you'll want to confirm your shaft matches that before ordering.
Question by: Frank Y on May 17, 2025, 7:08 PM
got a steering setup that needs 4 to 8 gpm, is this unit in the right wheelhouse for that?
Answer by: Customer Support on May 19, 2025, 10:31 AM
For flow, it’s set up for a 4 to 8 GPM range and the displacement is 7.30 cu in per revolution, so it matches that kind of steering circuit without needing to be pushed outside its stated flow window.
