TD-25M EXTRA DRESSTA
BULLGRADER „C“ FRAME
12. REMOVAL
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.
CAUTION! Due to the considerable weight and bulk of each bullgrader
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. Lower the blade (1, Fig.17.9) to the ground and install blocks under the front of the “C” frame (4).
2. Disconnect the lift cylinders from the “C” frame (4) by removing the pin locking hardware and
drive out the mounting pins. Hydraulically retract the rods and secure the cylinders to the main
frame radiator guard with the cylinder hanger and wire.
3. Disconnect left lower strut (3) from the “C” frame bracket by removing the lock pin and free the
strut trunnion from the “C” frame bracket. Flip the lower left strut (3) back away from the “C”
frame (4) and install blocks under the lower left strut (3). Repeat this procedure on the opposite
side of the machine.
4. Unscrew bolts (3, Fig. 17.11) and remove blade hoses connection cover (2) from “C” frame (1).
Repeat this step on the opposite side of the machine.
5. Machine with hydraulic tilt: Disconnect hoses (12, Fig. 17.10) from the right trunnion (26).
Remove hose guard (20) from the “C” frame and disconnect hoses (7 and 23) from the “C”
frame plate (11).
6. Disconnect the “C” frame (4, Fig. 17.9) from blade (1) by removing the cotter pin, mounting pin
(1.5) and drive out blade center pin (1.4). Using the hoist, remove the blade (1) with lower struts
(3) and upper struts (2) or tilt cylinders (2A).
7. Install blocks under the rear of the “C” frame (4) on each side of the machine. Unscrew two
trunnion cap bolts (5, Fig.17.11) and remove cap (4) with shims (6) from “C” frame (1). Repeat
this step on the opposite side of the machine.
8. Back the machine out from between the “C” frame (1).
9. Reassemble shims (6, Fig.17.11) and caps (4) to the “C” frame (1) and secure with bolts (5) to
prevent their damage or being lost.
