Danfoss OMT V HD 500, part number 151B2267, is an orbital hydraulic motor. The exact article is listed in the current manufacturer catalogue and is explicitly associated with the original dimensional drawing supplied in the local PDF. The nominal size 500 is a series designation; the drawing does not independently establish an exact geometric displacement.
The execution uses a splined shaft with a nominal diameter of 38.1 mm. The spline has 17 teeth, 12/24 pitch and a 30° pressure angle under ANS B92.1. Mounting tolerances and the part-number-specific reference lengths are retained on the complete original drawing.
Main port connection: 1 1/16-12 UN O-ring boss. Drain connection: 9/16-18 UNF O-ring boss. The exact drawing is the reference for thread depth, sealing arrangement and port position. BSP parallel connections and UN/UNF O-ring boss connections are different interfaces and require the corresponding mating fittings.
The V HD execution includes the flushing-valve arrangement shown on its factory drawing. Several nominally similar V HD articles use different flushing details; compare the exact part number and drawing rather than substituting a neighbouring article.
The local PDF is an exact article dimensional reference. It does not establish continuous, intermittent or peak operating-pressure, torque or flow ratings for this execution. Select the operating point from the applicable manufacturer performance information; no ratings from a neighbouring execution are inferred here.
