Non-Functioning or Poorly Functioning SBE 5T
Perform the inspection procedures listed above in Yearly Maintenance for SBE 5T. If you do not discover the problem
there, proceed as follows.
1. Unscrew the connector end cap retaining ring. Install a 2-pin
dummy plug with locking sleeve over the bulkhead
connector to provide a good grip and protect the connector
pins. Rotate the end cap back and forth while carefully
pulling the end cap away from the housing. Pull out the end
cap and attached electronics from the housing.
2. Verify that the magnet can spin freely and is not broken or damaged.
3. Look for other signs of damage on the electronics.
4. Inspect the connector end cap o-ring and the mating surface in the housing for dirt, nicks, and cuts. Clean as
necessary. If the o-ring or mating surface is damaged, return the pump to Sea-Bird for repairs.
• Sea-Bird recommends that connector end cap o-ring replacement be performed at the factory, because the
pump’s physical configuration makes customer-replacement of this o-ring difficult to perform without
special tools.
5. Apply a light coat of o-ring lubricant (Parker Super O Lube) to the o-ring and mating surfaces. Gently place a new
desiccant bag (PN 30558 – 1 gram) on the electronics (see Application Note 71 for desiccant use and
regeneration). Reinstall the electronics in the housing, until the o-ring has fully seated. Reinstall the retaining ring
on the connector end cap.
