Maintenance
5. Remove the four seal retainer screws and remove the seal retainer. The seal will now be exposed.
6. Pry the rotary seal from its housing using care not to damage the sealing surfaces (see Figure 4-7).
Inspect the shaft and seal surface for scratches or nicks (see Figure 4-8). Small wear marks are normal.
If the shaft and sealing surface are undamaged, clean both the shaft and seal assembly surfaces with a
lint-free rag and isopropyl alcohol.
If the shaft sealing surface is scratched (you can feel it with your fingernail), contact Aerotech customer
service.
If advised to remove the rotary union, see Section 4.4. for instructions.
