5. Draw out Gear wheel with ball race (pos. 8) and Ball retainer with balls (pos. 27).
6. Push out Stem (pos. 3).
If Ball races in Body (pos. 28.3) and on Gear wheel (pos. 8.1) are extremely worn they should be replaced together with 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. Alternatively, in many cases it is possible to purchase a complete Stem With Liners mounted for
your machine.
