CAUTION
Contact of O-ring with graphite or similar material
Fluid could escape!
▷ Do not coat O-ring with graphite or similar material.
▷ Use animal fats or lubricants based on silicone or PTFE.
▪ Assembly adhesives
– For gaskets, avoid the use of assembly adhesives, if possible.
–
If assembly adhesives are required, use a commercially available contact
adhesive (e.g. "Pattex").
– Only apply adhesive at selected points and in thin layers.
– Never use quick-setting adhesives (cyanoacrylate adhesives).
– Coat the locating surfaces of the individual components and screwed
connections with graphite or similar before reassembly.
For reassembly, tighten all screws and bolts as specified in this manual.

✓ The sealing surfaces have been cleaned.
WARNING
Hot surfaces due to heating of components for assembly/dismantling
Risk of burns!
▷ Wear heat-resistant protective gloves.
▷ Remove flammable substances from the danger zone.
1. Heat up angular contact ball bearing 320.02 and the inner ring of cylindrical
rolling element bearing 322.01 to approximately 80 ℃ in an oil bath or by
means of an induction heater.
2. Guide angular contact ball bearing 320.02 onto shaft 210 as far as it will go.
3.
