Should, of course,have an opening for the oil. If this PSRU was run on the dyno it sounds that like either: 1. This condition existed before the dyno runs (could be a missed step in manufacturing) or 2. The sleeve has sheared its pins and spun in the casting. Ed Ed; The run on the dyno was without redrive. It has now run less than 10 minutes at low rpm, but with no trace of oil in the drain line, clearly there never was any flow. Fortunately, I caught the problem early. Presumably no damage to the drive. Al ------=_NextPart_000_0037_01C48E15.7D60F4A0 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable
