16. Remove socket head bolts (29) that attach the gear-end bearing housing (3) to air cylinder (1).
17. Using bearing housing puller EQ144211-6, remove gear-end bearing housing. Install fixture and place
hydraulic cylinder between rotor shaft and fixture as shown in FIGURE 6-1. Apply pressure back and forth
between both rotor shafts evenly until bearing housing is free. Bearings (14), shims (39), and internal slingers
(11) will be removed in this process.

18. Reinstall gear-end bearing housing with two bolts (29) and rotate unit so drive-end is up.
19. Remove drive-end bearing housing (4) by repeating process in step 17.
20. Match mark rotors by making small punch marks on end of meshing lobes.
21. Using 3/4-10 UNC eye bolts and a hoist, remove both rotors (2) from cylinder.
22. Rotate unit so gear-end is up.
23. Remove two bolts (29) and remove gear-end bearing housing.
24. Position blower assembly horizontally.
25. Inspect piston rings (10) on both ends of both rotors for signs of damage and abnormal wear. Remove piston
rings from each of the four ring carriers (9).
26. Inspect ring carriers for signs of damage and abnormal wear. Piston ring carrier replacement is typically not
required. If no damage is visible, skip step 27.
27. Remove ring carrier by placing rotors in a vertical position and heating ring carriers evenly with a
torch. Caution should be used when performing this procedure as rotor can be damaged by uneven and/or
extreme heating.
28. Inspect inserts (7) in bearing housings (two in each bearing housing) for signs of damage and abnormal wear.
Insert replacement is typically not required. If no damage is visible, skip step 29.
29. Remove insert by removing retaining rings (8) and using a hydraulic press and suitable driver tool. It must be
pressed from air side of bearing housing.
