  Bill and interested others,
  
  I don't know how much Oildyne gets for the hyd. pwr. pk. but Lancair gets
  $600.00.  I asked about buying the unit direct from Oildyne but they do not
  want to get into the business of competing with their customers, which I can
  understand.  My discussions were with the engineers on these units (first
  names Bryan and Vern in Minneapolis) (763) 229-7859.  They estimated I had
  about 25 +/- continuous hours on my pump but given its age and
  considerations about the brushes and future problems, a new pump was the way
  to go.  That old pump was so darn hard to service and check with that tiny
  fill port and little stem, the new, big reservoir is almost worth the price.
  Also, my landing gear now come up very quickly, in roughly five seconds.
  That old pump would struggle over ten plus or minus seconds then run in
  short bursts for the next five getting the doors closed.  My occasional low
  and hot transition was getting to the point of exceeding the red line (120
  kts.) on the doors before they closed.
  
  The new high pressure switch is at 1100 psi and with the new pump no
  adjustment of the setting is required.
  
  Thanks for the input and suggestions from others when my problem surfaced.
  A little panic starts churning when there are unknowns happening and there
  is uncertainty.  More information on the table helps in sorting out the next
  step.
