SINGLE SHANK RIPPER
21. INSTALLATION (Refer to Fig. 17.15)
1. Clean mating surfaces of mounting frames (1 and 4) to rear main frame.
2. Using hoist on cylinder pin (2) place mounting frame (1) into position. Install hardware and
torque the bolts to 3100 ± 5 [%] [Nm]. Remove pin (2) from mounting frame (1).
3. Using hoist on cylinder pin (2) place mounting frame (4) into position. Install hardware and
torque the bolts to 3100 ± 5 [%] [Nm]. Remove pin (2) from mounting frame (4).
4. Attach hoist to draft frame (9) and place in position in mounting frames (1 and 4). Install
mounting pins (5), being careful not to damage bushings (8), and secure with plate and
hardware. Hoist draft frame (9) and support with blocking.
5. Attach hoist to cylinder pins (13) on tool beam (17) and place in position. Secure tool beam
(17) to draft frame (9) with pins (16), plates and hardware. Position suitable blocking under
tool beam (17).
6. Install ripper lift cylinders (7), refer to SECTION 10C.
7. Install ripper pitch cylinders (6), refer to SECTION 10C.
8. If removed, install shank (18 or 19) to tool beam (17).
MULTI SHANK RIPPER
22. REMOVAL (Refer to Fig. 17.16)
WARNING! Before working at the machine, be sure that the blade and ripper
have been lowered to the ground, engine is OFF, the drive train neutral lock lever
is in locked (ON) position and parking brake is set. The starting switch and the
electrical system master switch are turned OFF, keys are removed and the
controls are tagged to prevent inadvertent engine starting.
WARNING! Due to the considerable weight and bulk of each bulldozer
component, a suitable hoist or lifting device MUST be used. Remove each
component separately using suitable blocking on the remaining components.
IMPORTANT: Disconnected hydraulic lines must be capped with the correct size plastic cap.
If caps are not available, use tape or rubber stoppers. Openings must never be plugged with rags.
This practice could introduce dirt or lint into critical hydraulic components. Tag all disconnected
lines to facilitate proper installation.
1. Position suitable blocking under draft frame (9) and tool beam (16). Remove pitch cylinders
(6), refer to SECTION 10C. Reinstall mounting pins (2 and 13) in mounting frame (1 and 4)
and tool beam (16).
2. Remove ripper lift cylinders (7), refer to SECTION 10C. Reinstall mounting pins (2 and 11) in
mounting frame (1 and 4) and draft frame (9).
3. Attach hoist to cylinder mounting pins (13) at tool beam (16) and take out slack in hoist.
Remove draft frame pins (15) and lift tool beam (16) from ripper. If necessary, remove shanks
(17) from tool beam (16)
