⇒ Determine the wear on the following parts (Fig. ’D’) and compare it with the
permissible values mentioned in clearance table 0330−1:
− Scraper rings 2 and 6
− Sealing rings 3 and 4
D Parts which are beyond the admissible tolerance must be replaced. If neces-
sary remove scraper rings 6 from ring supports 5 and replace them with new
