6.5 Hub Subassembly
Disassembly
1. Remove Nozzles (pos. 22). Nozzles are untightened with a wrench on the faces of the Nozzles.
2. Remove Screws (pos. 17) and Spring washer (pos. 16) from Hub cover (pos. 21).
3. Draw out Hub (pos. 23) together with Hub cover (pos. 21), Ball race (pos. 21.1), Ball retainer with balls (pos. 27) and Bevel
gear (pos. 20). If Hub cover (pos. 21) clings into Body, knock carefully with plastic hammer on outer diameter to loosen.
If Ball races (pos. 20.1) and in Bevel gear (pos. 21.1) are extremely worn, they should be replaced as well as the Ball retainer
with balls (pos. 27). How to replace Ball races see page 34.
If blue liners on Stem are extremely worn, they can be replaced. This part requires that a precise procedure is followed to
accomplish installation. It is highly recommended that an authorized Alfa Laval Tank Equipment Service Center perform the
replacement when necessary.
