TROUBLESHOOTING
HIGH-PRESSURE SEAL LEAK:
• The high pressure seal may leak initially at lower pressures, but should pop closed as
pressure is increased. A continuous leak at operating pressure from the weep holes
indicates the need to replace the HP Seal and Seat. HP Seals wearing out too quickly
can be an indication that the HP Seat is installed upside-down, or the tool is rotating
too fast. If the tool is leaking, but not over rotating, the SC125 602 Seal Kit is required.
TOOL WILL NOT ROTATE:
•
Check the nozzles for plugging or wear (nozzles have to be removed to check for
obstructions).
•
Check that the nozzle sizes are correct for the desired flow and that the desired flow
matches the head flow range.
•
Check that the nozzle sizes are installed in a balanced configuration.
•
If the tool feels rough when manually rotating the head, this indicates internal
damage and SC125 610 Overhaul Kit will be required.
•
Check head by hand to make sure it rotates freely. If it does not rotate freely by hand,
the tool needs to be disassembled and repaired. Research from field reports show
that exceeding set-down weight may bend the headshaft ever so slightly and prevent
rotation.
TOOL ROTATES TOO FAST:
• If the head rotates too fast, clean out old lubricating fluid and replace with fresh
lubricant.
• If tool is showing heavy scuffing damage to body, we suggest that the customer
install an available fluted body on the SpinCat™.
STORAGE
TOOL STORAGE:
The SpinCat™ should NOT be stored in a used condition with wellbore and pumped fluids
possibly migrating into the lubricant chamber. Flush with fresh water and perform a seal
redress after HCL, Xylene or Toluene chemical treatment jobs. Downhole tools, especially
thru tubing tools tend to be stored upside down in tool racks with threaded stubs welded
to rack base. Storing the SpinCat™ in this manner allows air to collect at the top of the
lubricant chamber. We recommend the SpinCat™ be stored with inlet nut facing up to avoid
this air pocket. The SpinCat™ may also be stored horizontally.
