Usage:
1. Start the machine, and put it on a level floor. Connect steering frame lock link (1). This will prevent side-to-side movement of the yoke during removal of the drum assembly.
2. To prevent movement of the machine, put wood blocks in front of and behind each rear wheel.
3. Put tool (A) under the rear of the frame as shown. Installation of tool (A) will keep the machine level during removal of the drum assembly.
4. On CS-431B Vibratory Compactors, fasten a hoist to front scraper assembly (2) as shown. Remove six bolts (3), three from each side, the washers and nuts that hold the front scraper assembly to the yoke of the machine. Remove the front scraper assembly. Weight of the front scraper assembly is 125 kg (275 lb).
5. Check the condition of rubber scraper blade (4). If the rubber scraper blade is worn or damaged, use new parts for replacement. To remove the rubber scraper blade, remove nine bolts (5), the washers and scraper retainer (6) from the scraper mount.

6. Put identification marks on hoses (7), (8) and (9) as to their location on the vibratory motor. Disconnect the hoses from the vibratory motor. Put plugs in the ends of the hoses to keep dirt and debris out of the hydraulic system.
NOTE: Steps 7 and 8 are for Vibratory Compactors which are not equipped with an electrical quick disconnect on wire (11).
7. Remove guard (10) from over the magnetic sensor.
8. Put identification marks on electrical wires (11) as to their location on the magnetic sensor. Disconnect the wires from the sensor.

9. Disconnect the hose (12) from the front hydraulic secondary brake. Put a plug in the hose to keep dirt and debris out of the hydraulic system.
NOTE: When the two jack stands [tool (B)] are installed under the yoke as shown in Photo C32966P1, be sure they will not interfere with the drum assembly during its removal.
10. Raise each side of the yoke with a floor jack approximately 12.7 mm (.50 in). Install tool (B) under each side of the yoke as shown. This will relieve the tension on the rubber shock mounts for the drum assembly.
11. Put a wood block in front of and behind the drum assembly so it can not roll after the mounting hardware used to hold it to the yoke is removed.
12. Remove nine bolts (13), the washers and nuts that hold the drum assembly on the propel side of the yoke. Remove two bolts, nuts and washers (14) that hold the secondary brake to the yoke. The secondary brake will stay attached to the brake disc even after the brake mounting bracket is disconnected from the yoke.
13. Remove eight bolts (15), the washers and nuts that hold the drum assembly on the vibratory side of the yoke.
14. Remove spacers (16) from between the vibratory side of the yoke and the front and rear shock mount spacers.
15. Remove retainer plate (17) that holds the hydraulic hoses for the vibratory motor to the left side of the yoke.
16. Remove the retainer plate that holds the hoses for the vibratory motor at the left rear inside corner of the yoke. Move the hoses for the vibratory motor clear of the yoke. They can be draped over the yoke on the left rear side.
17. Fasten a hoist and strap as shown to rear shock mount spacer (20). Remove eight bolts (19), the washers and the nuts that hold the shock mount spacer to the shock mounts. Remove the shock mount spacer. Weight of the shock mount spacer is 24 kg (54 lb). Remove the front shock mount spacer in a similar manner.
18. Check the condition of rubber shock mounts (18). If the mounts show any indication of severe cracking, fatigue or breakage, use new parts for replacement. To remove rubber shock mounts (18), remove the four bolts, washers and nuts that hold each mount to the vibratory arm.

Because of the limited clearance between the yoke and drum assembly on each side, the drum assembly must be held straight during removal. It may be necessary to refasten the hoist, because the drum assembly is slightly heavier on the secondary brake side. Also, prior to removal of the drum assembly, be sure all hydraulic hoses are clear of the drum assembly. |
19. Fasten a hoist to drum assembly (21) as shown. Remove the wood blocks from in front of and behind the drum assembly. Raise the drum assembly until it just off of the floor. While keeping the drum assembly level, remove it from the yoke. Weight of a smooth drum assembly is 1882 kg (4150 lb). Weight of a padded drum assembly is 2132 kg (4700 lb).
20. On CS-431B Vibratory Compactors, fasten a hoist to the rear scraper assembly. Remove the four bolts, washers and nuts that hold the rear scraper assembly the the yoke. Remove the rear scraper assembly. Weight of the rear scraper assembly is 125 kg (275 lb). Check the condition of the rear rubber scraper blade. If the blade is worn or damaged, use new parts for replacement. To remove the rubber scraper blade, remove the six bolts, washers, nuts and the scraper retainer from the scraper mount.
21. If the drum assembly is to be disassembled, drain the lubricant from the vibratory bearing lube reservoir. Position the drum so the drain plug, which is located on the vibratory side of the drum, is at its lowest position. Remove drain plug (22) to drain the lubricant. The capacity of the drum is 18.9 liters (5 U.S. gal).
NOTE: The following steps are for the installation of the drum assembly.
22. Fill the vibratory bearing lube reservoir with lubricant to the correct level. See, "Vibratory Bearing Lube Reservoir" in the Operation & Maintenance Manual.

Do not reuse elastic filled stop nuts during installation of the drum assembly. The used nuts should be discarded and replaced with new parts. |
23. On CS-431B Vibratory Compactors, reinstall the rear scraper assembly in the yoke. Leave the rubber scraper blade on the scraper assembly loose. It will be adjusted after completing the installation of the drum assembly.
| NOTICE |
|---|
Do not damage any hydraulic hoses or electrical wires when the drum assembly is positioned in the yoke. |
24. Fasten a hoist to drum assembly (21) as shown. Put the drum assembly in position in the yoke. Ensure that the flat portion of the right hand drum support (23), is facing upward as shown.
25. Install four rubber shock mounts (18) on the vibratory arm, if they were removed.
26. Install front and rear shock mount spacers (20).
27. Install retainer plate (17) that holds the hydraulic hoses to the left side of the yoke.
NOTE: It may be necessary to move the drum assembly up and down or back and forth to put the mounting bolt holes on the vibratory side and the propel side in alignment with each other.
28. Install four spacers, two on each spacer, (16) between the vibratory side of the yoke and the two shock mount spacers. Install eight bolts (15), the washers and nuts that hold the drum assembly on the vibratory side of the yoke.
29. Install nine bolts (13), the washers and nuts that hold the drum assembly on the propel side of the yoke. Install two bolts washers and nuts (14) that hold the secondary brake to the yoke.
30. Raise each side of the yoke with a floor jack, and remove tool (B) from under each side of the yoke.
31. Check the condition of the o-ring seal in hose (12). If the seal is worn or damaged, use a new part for replacement. Connect the hose to its original location on the front hydraulic secondary brake.
32. Connect electrical wire (11) to the magnetic sensor on the drum support assembly (vibratory side). Install guard (10) over the magnetic sensor, if it was originally removed.
33. Check the condition of the o-ring seals in hoses (7), (8) and (9). If the seals are worn or damaged, use new parts for replacement. Connect the hoses to their original locations on the vibratory motor.
34. Fasten a hoist to front scraper assembly (2), and put it in position in front of the drum assembly between the arms of the yoke. Install six bolts (3), the washers and nuts that hold it. Leave the rubber scraper blade loose until completing the installation of the drum assembly.
35. Remove tool (A) from under the frame of the machine. Remove the wood blocks from in front of and behind the rear wheels. Disconnect the steering frame lock link.
36. Adjust the clearance between the rubber scraper blades and the drum assembly. See, "Drum Scrapers" in the Operation & Maintenance Manual.
37. Fill the hydraulic oil tank to the correct level. See, "Hydraulic Tank" in the Operation & Maintenance Manual for the correct filling procedure.
